Lewis, Erin. "Between yarns and electrons: A method for designing electromagnetic expressions in woven smart textiles." Artifact 9, no. 1 (December 1, 2022): 23.1–23.25. http://dx.doi.org/10.1386/art_00023_1.
Abstract:
The design of woven smart textiles presents a discrepancy of scale where the designer works at the level of structural textile design while facets of the material express at scales beyond one’s senses. Without appropriate methods to address these unknown (or hidden) material dimensions, certain expressional domains of the textile are closed off from textile design possibilities. The aim of the research has been to narrow the gap that presents when one designs simultaneously at the scale of textile structure and electron flow in yarns. It does this by detailing a method for sensing, visualizing, and discussing expressions of electromagnetism in woven smart textiles. Based on experimental research, a method of textile surface scanning is proposed to produce a visualization of the textile’s electromagnetic field. The woven textile samples observed through this method reveal an unknown textural quality that exists within the electron flow – an electromagnetic texture, which emerges at the intersection of woven design and electromagnetic domain variables. The research further contributes to the definition of specific design variables such as: field strength and diffusion expanding the practice of woven smart textile design to the electromagnetic domain.

Abstract:
Modern textile consumers are increasingly becoming more watchful of the quality of the textiles that they purchase. This has increased the need for textile producers, especially artisan textile makers (e.g., knitters, tailors, dressmakers, seamstresses, and quilters), to improve the quality of their textile products. Information on several analytical tools that are commonly used for assessing the quality of textiles is abundant, but consumer-based tools for evaluating the quality of textiles remain limited. A consumer-based artisan textile-quality scale was developed using data collected from two focus groups (Phase 1) and a consumer quantitative study, n = 196 (Phase 2). Ten scarves and shawls were evaluated in the quantitative study and analysis of variance (ANOVA) was used to determine the differences between the mean textile ratings for all the statements. Coefficient alpha (final raw alpha = 0.87) was also used to assess if the statements were consistent in the way they measured the quality of the textiles. Pearson correlation tests were used to validate the six-statement quality scale that included statements such as overall attention to detail, the fabric is durable, and stitching is even and consistent. Artisan textile makers in the USA can use this scale to better meet the functional needs of their customers. Additionally, the process that was employed in the development of the six-statement quality scale can be used by researchers in other countries to understand better the key quality characteristics of artisan as well other textile products.

Abstract:
PurposeThe quality of produced textile fibers plays a very important role in the textile industry, and detection and assessment schemes are the key problems. Therefore, the purpose of this paper is to propose a relatively simple and effective technique to detect and assess the quality of produced textile fibers.Design/methodology/approachIn order to achieve automatic visual inspection of fabric defects, first, images of the textile fabric are pre-processed by using Block-Matching and 3-D (BM3D) filtering. And then, features of textile fibers image are respectively extracted, including color, texture and frequency spectrum features. The color features are extracted by using hue–saturation–intensity model, which is more consistent with the human vision perception model; texture features are extracted by using scale-invariant feature transform scheme, which is a quite good method to detect and describe the local image features, and the obtained features are robust to local geometric distortion; frequency spectrum features of textiles are less sensitive to noise and intensity variations than spatial features. Finally, for evaluating the quality of the fabric in real time, two quantitatively metric parameters, peak signal-to-noise ratio and structural similarity, are used to objectively assess the quality of textile fabric image.FindingsCompared to the quality between production and pre-processing of textile fiber images, the BM3D filtering method is a very efficient technology to improve the quality of textile fiber images. Compared to the different features of textile fibers, like color, texture and frequency spectrum, the proposed detection and assessment method based on textile fabric image feature can easily detect and assess the quality of textiles. Moreover, the objective metrics can further improve the intelligence and performance of detection and assessment schemes, and it is very simple to detect and assess the quality of textiles in the textile industry.Originality/valueAn intelligent detection and assessment method based on textile fabric image feature is proposed, which can efficiently detect and assess the quality of textiles, thereby improving the efficiency of textile production lines.

Abstract:
Stainless steel fiber is a new sort of soft industrial material developed in the past decades. The pure stainless fiber has a number of outstanding properties and is getting wider range of application in textiles which are used as industrial textiles. The tensile properties between stainless steel fiber and traditional textile fibers are quiet different. The property differences between stainless fiber and common textile fiber made the textile processing of stainless fiber difficult. Based on the testing of breaking force, breaking strength and breaking elongation rate, this paper analyzed the tensile characteristic of stainless fiber and discussed its effect on yarn quality.

Abstract:
Industrial textiles is designed with engineering structure textiles. Transportation textiles is one of the main types of industrial textiles. Automobile seat fabric is one of the decorative materials in automobile textile fabrics. The fabric should have soft handle, good air permeability, coordinate color, luxury and generous pattern, wear-resisting, anti-fouling, flame retardant, certain friction factor and antistatic property. In recent years, requirements for automobile textiles of safety, health, environmental protection is more and more high. In order to evaluate the automobile seat woven fabric quality, need to have a simple and effective standard. Quality indexes should be comprehensive. The test method of quality index should be operable. In the existing relevant standards, the test content is not consistent. The existing relevant standards are national standards, textile industry standards and automotive industry standards. Within textile industry standard FZ/T 24005-2010 wool textiles for chair, the technical requirements include safety specification, classification rules, physical quality rating, internal quality rating, appearance quality rating. For flame retardant performance, must meet the following requirements: damaged length ≤200mm, afterflame time ≤15s. Within national standard GB 8410-2006, flammability of automotive interior materials, for flame retardant performance, must meet the following requirements: burning rate ≤100mm/min. Within automotive industry standard QC/T 633-2009 the seats of passenger vehicles, for safety specification, seat fabric must meet the B grade in GB 18401. Based on some effective standard, established suitable standard for automobile seat woven fabric. The standard covers quality evaluation content, performance levels and the methods of test to be used to determine these performance levels.

Abstract:
Given their organic origin, textiles rank among the rarest archaeological finds. While the vast majority of these artefacts are preserved as small fragments or mineralised remnants, their detailed textile technology study provides interesting and important information about the use of textile techniques and the quality of processing. The most important information concerns the utilised textile materials, but for degraded textiles, these materials are among the most difficult information to obtain. Image analysis using electron microscopy (SEM) is a significant aide in this pursuit.

Abstract:
Abstract It is well known that textiles and textile products may contain hazardous compounds. Formally, all imported textiles and textile products must be registered through the Indonesian Custom. Ideally, the Indonesian Custom has the capability to detect chemicals of concern in textiles or textile products entering Indonesian territory. However, this is not the case, particularly for chemicals listed in the Stockholm Convention. The difficulties arise from the lack of identification regarding substances listed in the Stockholm Convention that might be present in textiles, textile products, and finished products. The Indonesian Government has initiated programs to assess the presence of persistent organic pollutants (POPs) in Indonesian territory. Results of the assessment were elaborated in the National Implementation Plan Document on POPs, which was updated recently. Not all substances listed in the Stockholm Convention can be described in depth. Some POPs such as short-chain chlorinated paraffins (SCCPs) and polychlorinated naphthalenes have not been included in Indonesian regulation, particularly in Indonesian Customs Tariff Book, making it extremely difficult to assess them. Nevertheless, a preliminary assessment of polybrominated diphenyl ethers and SCCPs has been carried out. Using the Tier 1 approach, it was revealed that 2,194 tonnes of SCCPs was imported from India to Indonesia, which was listed under HS code 38249090 that covered CP52 (containing 50–54% chlorinated paraffins). Furthermore, another prominent issue for chemicals of concern (CoC) in textiles was the use of lead-containing dyes, nonylphenols, and nonylphenol ethoxylates. The latter two compounds are known to be used in detergents and surfactants during textile manufacturing processes. At present, nonylphenols and nonylphenol ethoxylates are not listed in Indonesian laws for regulated chemicals in textiles and textile products, as well as in the wastewater quality standard for the textile industry. Therefore, to avoid circular economy obstacles of used textiles and textile products and support sustainable Indonesian textiles, a systematic inventory of CoC in textiles is very important.

Renne, Elisha P. "United Nigerian Textiles Limited and Chinese–Nigerian textile-manufacturing collaboration in Kaduna." Africa 89, no. 4 (November 2019): 696–717. http://dx.doi.org/10.1017/s000197201900086x.
Abstract:
AbstractIn 1964, the newly established Hong Kong-based Cha Group partnered with the Northern Nigerian Regional Development Corporation to open the United Nigerian Textiles Limited (UNTL) mill in Kaduna – the largest textile mill in Northern Nigeria. The Cha Group later expanded, building textile mills in other parts of the country. Both Chinese and Nigerian managers and workers were involved in UNTL mills, which by 1980 provided printed cotton textiles for the Nigerian market and for other markets in West Africa. Yet this Chinese–Nigeria collaboration could not overcome factors external to the textile-manufacturing industry. Declining infrastructure, erratic electricity, frequent changes in political leadership at the federal level, and the smuggling of less-costly imported textiles (often from China) undermined local textile manufacturing, while inflationary pressures associated with the national oil industry undermined agricultural production, exacerbating the difficulties of obtaining raw Nigerian cotton. In 2007, the UNTL mill in Kaduna closed, although it resumed production in December 2010, assisted by the 100 billion naira Cotton, Textile and Garment Development Fund. Cha Group officials also used their knowledge of the Nigerian textile market as the basis for the marketing of branded, high-quality manufactured textiles, known as Da Viva®, at company-franchised shops in major Nigerian cities. The Cha Group took advantage of digital innovation, both in the printing of these popular textiles and also by advertising them on an attractive website. This article considers the ways in which the United Nigerian Textiles Plc company has maintained production of grey cloth and printed textiles at its mills in Kaduna and Ikorodu-Lagos, along with the marketing of Da Viva® cotton prints, which suggests the continuing, if contradictory, possibilities for this Nigerian–Chinese textile-manufacturing collaboration.

[Comparative Study Of The Products Resulting From The Transformation Into Spinning Of The Fibers Of Three New Varieties Of Cotton]Abstract - In Mali, as elsewhere in Africa, varietal selection is the basis of the success of cotton growing. Cotton from Mali is almost entirely exported; fibers from cultivated varieties must meet market requirements in terms of the technological characteristics of fibers, key factors in the operation of the spinning mill. This comparative study was carried out on three new varieties of cotton A, B and C, from an experimental point. The objective of the study is to identify the varieties with the best varietal and industrial performance for popularization in commercial production by cotton companies. 1 representative sample of 100g of cotton fiber, 20 samples of 5m of carding and drawing slivers and 10m of rovings, 30 samples of 100m of yarn and 40 samples of 500mm of yarn were respectively taken per bale of each variety and at different stages of the transformation process by variety. These samples were tested on measuring devices under the required conditions at the CERFITEX textile metrology laboratory, Ségou - Mali.The analysis of variance (ANOVA) of fiber, sliver, roving and yarn data and the comparison of their main quality characteristics to that of world production with the application of USTER STATISTICS 2018 showed that cotton varieties A and B are clearly better than those of C.

Abstract:
The chemical recycle of cotton textiles and/or other cellulosic materials for the purpose of manufacturing regenerated high quality textiles fibres is a novel process. The objective of related research is based on the forecast of population growth, on resource scarcity predictions, and on the negative environmental impact of the textile industry. These facts lead the need of broadening the scope for long-term textile-to-textile recycle - as the mechanical recycle of natural fibres serve for limited number of cycles, still depends on input of virgin material, and offer a reduced-in-quality output. Critical analysis of scientific papers, relevant related reports, and personal interviews were the base of this study, which shows viable results in laboratorial scale of using low-quality cellulosic materials as input for the development of high-quality regenerated textile fibres though ecological chemical process. Nevertheless, to scale up and implement this innovative recycle method, other peripheral structures are requested, such as recover schemes or appropriate sort, for instance. Further researches should also be considered in regards to colours and impurities.

Abstract:
Post-consumer bio-based textile wastes are any type of garment or household article made from manufactured bio-based textiles that the owner no longer needs and decides to discard. According to the hierarchy of waste management, post-consumer textile waste should be organically recycled. However, there is still a problem with the implementation of selective collection of textile waste followed by sorting, which would prepare the waste for organic recycling. A technically achievable strategy for sorted textile waste materials consisting of only one type of fiber material, multi-material textiles are a problem for recycling purposes. Waste textiles are composed of different materials, including natural as well as synthetic non-cellulosic fibers, making bioprocessing difficult. Various strategies for recovery of valuable polymers or monomers from textile waste, including concentrated and dilute acid hydrolysis, ionic liquids as well as enzymatic hydrolysis, have been discussed. One possible process for fiber recycling is fiber recovery. Fiber reclamation is extraction of fibers from textile waste and their reuse. To ensure that organic recycling is effective and that the degradation products of textile waste do not limit the quality and quantity of organic recycling products, bio-based textile waste should be biodegradable and compostable. Although waste textiles comprising a synthetic polymers fractions are considered a threat to the environment. However, their biodegradable part has great potential for production of biological products (e.g., ethanol and biogas, enzyme synthesis). A bio-based textile waste management system should promote the development and application of novel recycling techniques, such as further development of biochemical recycling processes and the textile waste should be preceded by recovery of non-biodegradable polymers to avoid contaminating the bioproducts with nano and microplastics.

Abstract:
Avec la crise économique, la dynamique de développement industriel émanant de la grande entreprise travaillant sur anticipations longues, avec des équipements rigides et une organisation taylorienne du travail, a été radicalement remise en cause. Des régions entières, organisées autour des grandes entreprises, ont été particulièrement touchées par la récession et le chômage. Dans le même temps, des régions composées majoritairement de PME non seulement se maintiennent dans la crise, mais ont parfois atteint un développement économique notable. Cette évolution favorable des PME dans la crise signifie-t-elle que les systèmes industriels locaux sont à l’origine d'un nouveau mode de développement économique ? Pour répondre à une telle question, il nous paraît nécessaire de retracer les grandes lignes de développement d’un système industriel localisé. Cette analyse sera réalisée à partir des événements qui ont affecté ce système dans le passé, et en particulier des restructurations qui l’ont suivi. L’objet de cet article est d’analyser l’évolution de l’industrie textile dans la région de Roanne (ville industrielle française, proche de Lyon) à la fin des années 1980, en vue de rapporter l’émergence de nouveaux modèles de développement. La dispersion géographique et la petite taille des firmes qui, au milieu des années 60, apparaissaient comme un handicap face aux formes de modernisation imposées par la production en grandes séries, sont actuellement considérées comme des éléments de flexibilité et des facteurs de succès économique. Les principaux arguments de l’étude concernent les facteurs de développement propres aux systèmes industriels localisés. L’organisation de ia production nous apparaît comme le premier facteur de développement des systèmes industriels locaux. Les stratégies commerciales des firmes, en particulier, nous paraissent un facteur essentiel pour expliquer l’organisation d’un système productif local. Un troisième facteur d’analyse concerne le rôle des politiques de soutien au développement industriel local. Notre analyse du système textile est basée sur des entretiens avec des chefs d’entreprises, des responsables locaux administratifs et politiques. Nous avons relevé les modèles d’organisation de la production qui caractérisent le système industriel roannais avant la restructuration, pendant la crise, et après la restructuration. La première période, de 1964 à 1980, correspond à ce que nous avons appelé le « modèle de production traditionnel » ; le début des années 1980 voit l’éclatement du modèle traditionnel et l’émergence de nouvelles tendances issues des nouvelles stratégies commerciales et des changements dans la qualité des produits; la fin des années 1980 consacre la stabilisation de ces nouvelles dynamiques de développement industriel. Il reste à savoir si le système textile roannais, dans l’hypothèse où l’organisation actuelle se stabilise, constitue encore un système industriel local alors qu’il n’a plus de développement endogène et qu’il ne repose plus sur un modèle unique de développement

Abstract:
Abstract Wearable smart textiles have garnered significant interest due to their high flexibility, reusability, convenience and ability to work on home-based, real-life and real-time monitoring. Wearable smart textiles are shirts with inbuilt textile sensors that enable electrocardiogram (ECG) data to be collected more comfortably and smoothly outside the laboratory and clinical environment for a continuous and longer duration for ECG data collection. However, the existing ECG wearable smart textile main challenge is maintaining the quality and reliability of data across multiple wearable smart textile shirts. Therefore, this research analyses the capability of ECG morphology during Feature Extraction stages for different wearable smart textile shirts. This paper reports the experiment conducted on eleven healthy volunteers, either wearing the Hexoskin smart shirt or the HeartIn Fit shirt or both. ECG data were recorded while they are doing normal daily routine activities for at least 45 minutes. The study demonstrates a significant possibility of reliability in Feature Extraction stages at different time instances among subject and wearable smart textiles shirts. With R peaks average between 0.543 to 1.194 mV and R-R interval average between 0.625 to 0.799 seconds, the study concludes that both wearable smart textiles do not significantly differ in Feature Extraction stages. Thus, both wearable smart textiles gave a significant result, although both are affected by their wearer’s motion artefacts during the shifting of body postures and the wearer’s body physical states. Furthermore, the ECG morphology in this study has yielded a promising result in real life and as on-the-go ECG smart textile biometric readiness for future explorations.

Abstract:
Many electronic textile (e-textile) applications require a stretchable basis, best achieved through knitted textiles. Ideally, conductive structures can be directly integrated during the knitting process. This study evaluates the influence of several knitting and material parameters on the resistance of knitted conductive tracks after the knitting process and after durability testing. The knitting speed proves to be of little influence, while the type of conductive thread used, as well as the knitting pattern both impact the resistance of the knitted threads and their subsequent reliability considerably. The presented research provides novel insights into the knitting process for conductive yarns and possible applications and shows that choosing suitable material and processing methods can improve the quality and robustness of knitted e-textiles.

Abstract:
The textile and apparel production and consumption generate a huge amount of solid textile waste. Mechanical recycling is one main method to recycle cotton waste; however, shredding in mechanical recycling shortens fiber length and reduces fiber quality. As a result, the application of mechanically recycled textiles may be limited. This research investigated mechanical methods to recycle post-consumer cotton textile waste and designed and developed second-life products. This study applied research through design methodology and documented step-by-step textile and product development practices to communicate the results. Using the textiles from deconstructed end-of-use garments with a high cotton content (80% or higher), combined with other materials, the researchers developed yarns, and nonwoven, woven, quilted, tufted fabrics. The researchers tested textile properties such as “yarn” tensile strength and elongation, fabric thickness, thermal resistance, air permeability, and stiffness. Using fabrics developed from end-of-use cotton waste, the researchers designed and developed high-value products such as bags, decorative textile, a hat, cell phone and glasses cases, and garments to contribute to the sustainability and circularity of cotton.

"Preparation and Characterization of Non-Crimping Laminated Textile Composites Reinforced with Electrospun Nanofibers." Nanomaterials 13, no. 13 (June 27, 2023): 1949. http://dx.doi.org/10.3390/nano13131949.
Abstract:
This research investigated the use of electrospun nanofibers as reinforcing laminates in textiles to enhance their mechanical properties for use as smart and technical textile applications. Crimping plays a crucial role in textiles. Because of crimp, fabrics have extensibility, compressibility, and improved quality. Although crimping is inevitable for fabrics used in smart textiles, it is also a disadvantage as it could weaken the fibers and reduce their strength and efficiency. The study focused on preparing laminated textile composites by electrospinning a polyacrylonitrile (PAN) polymer onto textile fabric. The research examined the effect of electrospun nanofibers on the fabric by using a tensile testing machine and scanning electron microscopy. The results revealed that the prepared laminated textile was crimp-free because of the orientation of the nanofibers directly electrospun on the fabric, which exhibited perfect bonding between the laminates. Additionally, the nanofiber-reinforced composite fabrics demonstrated a 75.5% increase in the elastic moduli and a 20% increase in elongation at breaking. The study concluded that the use of electrospun nanofibers as laminates in textile composites could enhance the elastic properties, and prepared laminated composites will have the advantages of nanofibers, such as crimp-free elastic regions. Furthermore, the mechanical properties of the laminated textile composite were compared with those of the micromechanical models, providing a deeper understanding of the behavior of these laminated composites.

Abstract:
Renewable energy from thermal valorization plays a key part in today’s energy from natural cellulosic textiles that are resourceful biomass and safe from toxicity at high temperature treatments. The situation is opposite, when technical textiles are treated with synthetic chemical finishes adding functionality as anti-bacterial, water repellent or flame retardant, etc. Incineration of flame retardant textile results in possible unfavorable gases, toxic fumes and contaminated ash. Other thermal valorization techniques like gasification would assist in avoiding the formation of additional toxic hazards. Herein, gasification of flame retardant textile is carried out the likelihood to get quality gas composition. For comparative analysis, flame retardant textiles, after their flame retardant ability being revoked, are also gasified. The output gas components suggested that gasification can be a useful thermal valorization approach for flame retardant textiles and relevantly improved gas composition was seen in textiles with their flame retardant substrate/species being removed.

Abstract:
Materials science breakthroughs have regenerated high value fibres from end-of-life cellulose-based textiles that can be introduced into existing textile fabrication processes from raw material to textile product in established textile value chains. Scientific developments with regenerated cellulose fibres obtained from waste textiles suggest their potential to replace virgin resources. The current scale-up of regeneration technologies for end-of-life cellulose-based textiles towards pilot and commercial scales can potentially achieve a future materials circularity, but there is a lack of a long-term view of the properties of materials after consecutive recycling stages take place. Cellulose-based materials cannot be infinitely recycled and maintain the same quality, a factor which may provide new challenges for future textile processes in the context of the circular bioeconomy. This paper maps collaborative design and materials science projects that use regenerated cellulose obtained from waste feedstock according to materials in the value chain they seek to substitute. It also presents four new processes that use regenerated cellulose materials in relation to their intervention in the value chain (as determined in a PhD investigation). A framework is presented to demonstrate how these circular material design processes take place at earlier stages of the textile value chain after subsequent regeneration stages.

Abstract:
Bark extracts are important sources of natural dyes. They possess many functional properties of potential interest to the textile industry. Currently, textiles with eco-friendly functional finishing are increasingly sought for in medical and protective clothing due to stringent environmental laws and the associated toxicity of synthetic agents. In view of this, recent studies on bark extracts for multi-functional finishing of textiles, particularly for antimicrobial and UV protective finishing, is reviewed. Bark extracts from various trees are able to effectively impart antimicrobial resistance and UV protection properties to treated fabrics; however, their long-term sustenance and strength depend on a multitude of factors. However, the application of bark extracts on several types of textile fabrics have no significant impact on textile quality.

Abstract:
Textile waste constitutes a significant fraction of municipal solid waste sent to landfill or incinerated. Its innovative management is important to enhance sustainability and circularity. This review aims to present the latest policies and the state-of-the-art technologies in the collection, sorting and recycling of textile waste. Policies at global and regional levels are increasingly made to address the sustainability of the textile industry and integrate the concept of circular economy. They are crucial to driving changes and innovations in current textile waste management. The Internet of Things, big data, blockchain and smart contracts have been proposed to improve transparency, traceability and accountability in the textile waste collection process. They optimize collection routes, and transactions and agreements among stakeholders. The sorting of textile waste using near-infrared spectroscopy, optical sorting and artificial intelligence enables its separation based on composition, color and quality. The mechanical recycling of textiles regenerates fibers with the same or different applications from those of the original fabrics. Fibers have been used for making building and slope protection materials. Chemical recycling depolymerizes waste textiles using chemicals to produce monomers for new textiles or other materials, while biological recycling uses enzymes and microorganisms for this purpose instead of chemicals. Thermal recycling recovers energy and fuels from textile waste through pyrolysis, gasification and hydrothermal liquefaction. These innovations may have the drawbacks of high cost and scalability. This review contributes to decision making by synthesizing the strengths and weaknesses of the innovations in textile waste management.

Abstract:
The potential for using discarded viscose textiles to produce high-quality viscose fibres is limited by the low molecular weight of the cellulose and its continued reduction in the recycling process. Herein, we present a straightforward approach of reprocessing discarded viscose textiles while achieving high-quality recycled viscose fibres. Discarded viscose textile was defibrated and centrifuged, and the resulting fibres were reprocessed under industrially relevant conditions. The produced viscose dope was fluid and resulted in viscose fibres with properties comparable to fibres made from commercial wood cellulose pulp (titer ~2 dtex; dry elongation ~16%, dry tenacity ~15 cN/tex). To explore the potential for a more environmentally friendly production process, the steeping step was performed twice (double-steeping), thereby producing a more homogeneous viscose dope. Through double-steeping, the consumption of carbon disulfide (CS2) could be reduced by 30.5%. The double-steeping method shows to be a suitable approach to reprocess discarded viscose textiles while reducing the environmental impact of the viscose process associated with the use of CS2. Our work demonstrates that discarded viscose textile has the potential to be part of a circular textile value chain.

Abstract:
The need for ready-made clothing and home textiles produced from natural and synthetic fibres is increasing day by day in order to meet the needs of the increasing world population. Recently, the concepts of sustainability and recycling have gained importance in the textile industry. The rapid change in today's trends has developed disposable habits. Due to the rapidly changing fashion trends, the product variety has increased and mass production has been preferred. Therefore, the priority for customers to choose the products was not the material used, but whether they fit the current fashion trend. Thus, the use and production of natural fibres should be increased to reduce environmental pollution and meet production demand. Thanks to recycling, it is possible to reuse the waste textile materials that we leave to nature. Due to the increase in agricultural production costs, it has become difficult to obtain the raw materials used for textiles. When a life cycle system is created for raw materials that evaluate them until it is produced in nature and then return to nature, production with textile waste recycling can be advantageous. Using natural waste fibres instead of natural virgin fibres to produce home textile products both reduces costs and makes production easier. In this study, recycled (waste) cotton was obtained by shredding white, 100% cotton woven duvet covers and sheets purchased from a private hospital. A 50%-50% waste-natural blend was created from the cotton obtained. 54 wire reference fabrics were woven using open-end yarns numbered Ne24 and Ne12 produced from this blend. The physical characteristics of the fabric were investigated. The results obtained were analysed statistically and the effect of the blend created on the fabric quality was comprehensively examined.

International Journal of Progressive Sciences and Technologies 39, no. 1 (June 20, 2023): 127. http://dx.doi.org/10.52155/ijpsat.v39.1.5364.
Abstract:
Résumé—Contexte : Les effluents issus des industries textiles génèrent des charges chimiques importantes, ce qui pose un vrai problème à l’homme et à l’environnement. A Antananarivo, quelques industries textiles déversent leurs eaux usées fortement colorées dans la rivière Ikopa, avec ou sans traitement préalable. Cependant, ces eaux usées ont des impacts majeurs, directs ou indirects, sur la ressource en eau, car elles affectent la qualité de la rivière et les activités des riverains environnants. Objectif : L’objectif de cette étude est d’élaborer une méthode écologique pour éliminer le colorant d’indigo carmin (IC) qui est déversé directement dans la rivière Ikopa après le traitement de jeans (lavage et délavage) d’une entreprise franche. La décoloration a été réalisée par adsorption du colorant sur du charbon actif à base de coques de noix de coco (CACC). Méthode : L’adsorption est effectuée par mise en contact de l’indigo carmin / charbon actif (CACC) en poudre avec une vitesse d’agitation de 120 tr.min-1 . Les influences des paramètres liés aux conditions d’adsorption tels que le temps de contact, la quantité de l’adsorbant, la concentration du colorant ont été examinés. Après les différentes opérations, les échantillons sont ensuite filtrés, centrifugés et sont analysés par un spectrophotomètre UV-Vis à une longueur d’onde de 610 nm. Pour décrire les propriétés du mécanisme d’adsorption, on a aussi déterminé les modèles cinétiques et les modèles d’isotherme d’adsorption du colorant sur le CACC. Résultats : Le colorant d’indigo peut être éliminé à 98, 04 % pour une quantité optimum de 750 mg de charbon actif en poudre dans une solution expérimentale de 100 ml. La quantité de colorant adsorbée par le charbon est de 6,47 mg g-1. Le temps d'équilibre exact est obtenu en 40 minutes. On constate que la capacité d’adsorption augmente avec la masse de charbon grâce à la disponibilité des sites libres. En appliquant les équations cinétiques, on observe que le modèle de pseudo second-ordre décrit davantage l’adsorption de l’indigo carmin sur le CACC avec un coefficient de corrélation élevé (R2= 0,9998) et de qe,calc = 6,85 mg g-1. Le modèle de Freundlich est représentatif du processus d’adsorption du colorant IC, c’est-à-dire que l’adsorption est en multicouche et que la surface de l’adsorbant est hétérogène.Mots-clés: Effluent textile, indigo carmin, adsorption, rivière Ikopa, Antananarivo

Abstract:
Colonial chroniclers marveled at the quality and variety of textiles produced at the Postclassic center of Cholula. As a principal market center, textiles were produced for tribute and exchange, and other woven goods were manufactured for local consumption. This paper examines ethnohistorical and archaeological evidence to interpret the technology, materials, scale, and social relations of textile production. Original spindle-whorl data from the UA-1 domestic compound is contrasted with other whorls from Postclassic Cholula and from other sites in central Mexico. Results of this analysis indicate the complexity of pre-Columbian textile production and the significance of spinning and weaving in economic and social reconstructions of the past.

Abstract:
Textiles have been used in our daily life since antiquity in both economies and social relationships. Nowadays, there has never been a greater desire for intelligent materials. Smart fabric textiles with high-quality and high-performance fiber manufacturing with specific functions represented by clothing and apparel brands (such as astronaut suits that can regulate temperature and control muscle vibrations) are becoming increasingly prominent. Product applications also extend from the field of life clothing to the medical/health, ecology/environmental protection, and military/aerospace fields. In this context, this review proposes to demonstrate the recent advances and challenges regarding smart fabric textiles. The possibilities of innovative smart textiles extending the overall usefulness and functionalities of standard fabrics are immense in the fields of medical devices, fashion, entertainment, and defense, considering sufficient comfort as a parameter necessary for users to accept wearable devices. Smart textile devices require a multidisciplinary approach regarding the circuit design of the development of intelligent textiles, as the knowledge of intelligent materials, microelectronics, and chemistry are integrated with a deep understanding of textile production for optimum results.

Abstract:
The range and volume of textile products used every day is growing exponentiallythroughout the world, in both developed and developing countries. Therefore, the issues of waste Management and valorization become a challenge that requires depth economic and technical studies. In this setting, we aimed in this paper to give an added value of two kinds of textile wastes: yarns and textiles garments wastes collected from Blue denim manufacturer. A quality assessment of the reclaimed fibers shows satisfying physical and mechanical properties that allow them to be used to produce nonwoven textiles materials. A set of properties are investigated and results revealed that nonwoven structures can be considered as a good alternative for yarn and woven recycled fibers exploitation.

Abstract:
Additive manufacturing (AM) is a 3D printing technology that works by deposition of a material, layer by layer, creating 3D objects. The growth of these technologies has been exponential and the application of AM in the textile industry has also been a subject of increased interest in the past few years. The applications are not only for decorative purposes, but also for biomedical and other uses in e-textiles. However, a crucial point for making such assembly is the adhesion between the material and the textile substrate, as well as the premise of meeting demanding wash resistance requirements. This work aims to investigate the possibility of creating sensors by combining textiles with conductive polymeric filaments used in 3D printing. Merging the flexibility of use, mechanical properties and electrical conductivity of the polymeric filaments with the comfort and physical properties of the textiles can be a promising approach to create novel sensing structures. In this document, we give an overview of the recent state of the art of experimental research on adhesion in textile and polymer composites as well as an optimization of the printing parameters with a conductive filament, PI-ETPU. Some results from the printed samples in terms of print quality and electrical resistance are presented. Combining both topics, further work will include printing with conductive filament on textile substrates to study the possibly of creating sensing and electrical connections.

Abstract:
The aim of this report is to provide a summary of the latest developments in the textile archaeology of Greece and the broader Aegean from the Neolithic through to the Roman period, focusing in particular on recent research on textile tools. Spindle-whorls and loomweights appeared in the Aegean during the Neolithic and by the Early Bronze Age weaving on the warp-weighted loom was well established across the region. Recent methodological advances allow the use of the physical characteristics of tools to estimate the quality of the yarns and textiles produced, even in the absence of extant fabrics. The shapes of spindle-whorls evolved with the introduction of wool fibre, which by the Middle Bronze Age had become the dominant textile raw material in the region. The spread of discoid loomweights from Crete to the wider Aegean has been linked to the wider Minoanization of the area during the Middle Bronze Age, as well as the mobility of weavers. Broader issues discussed in connection with textile production include urbanization, the spread of different textile cultures and the identification of specific practices (sealing) and previously unrecognized technologies (splicing), as well as the value of textiles enhanced by a variety of decorative techniques and purple dyeing.

Abstract:
Textile-based supercapacitors incorporated into military uniforms enable the autonomy of wearable, physiological sensors that can be safer and more comfortable for the Warfighter. Previously, researchers have incorporated supercapacitor electrode components into common textiles such as cotton and polyester, but not in military-relevant textiles that have different fabric characteristics. In order to understand how current uniforms could be transformed into energy storage, a baseline for incorporating aforesaid components onto military textiles is needed. This paper describes how screen printing was used to assess the feasibility of the technique to incorporate electrode ink comprised of activated carbon and an acrylic binder onto military relevant textiles. Sheet resistance was used as a metric to evaluate the quality of screen prints, while electrochemical impedance spectroscopy and cyclic voltammetry were used to investigate the behavior of the most promising screen printed textile electrode using ionic liquid electrolyte (1-ethyl-3-methylimidazolium tetracyanoborate) and graphene foil as current collectors. It was found that the electrode ink favored military textiles that had a tighter weave and were partially composed of nylon. Screen printed spandex woven textiles were found to have the highest conductivity, attaining areal and gravimetric capacitances of 20 mF/cm2 and 4.21 F/gcarbon, respectively.

This review interested in using green chemistry application in dyeing textile fabrics with economic methods. It is also interested in application of nanotechnology in pre-treatment of wool fabric and dyeing with natural dyes. There is a great demand for antimicrobial textiles based on non-toxic and eco-friendly bioactive compounds. Consequently the review aimed to use natural compounds for treatment of textile fabrics before dyeing with natural dyes to enhance dyeing quality and antimicrobial activity.

Abstract:
The continuous and long-term measurement and monitoring of physiological signals such as electrocardiography (ECG) are very important for the early detection and treatment of heart disorders at an early stage prior to a serious condition occurring. The increasing demand for the continuous monitoring of the ECG signal needs the rapid development of wearable electronic technology. During wearable ECG monitoring, the electrodes are the main components that affect the signal quality and comfort of the user. This review assesses the application of textile electrodes for ECG monitoring from the fundamentals to the latest developments and prospects for their future fate. The fabrication techniques of textile electrodes and their performance in terms of skin–electrode contact impedance, motion artifacts and signal quality are also reviewed and discussed. Textile electrodes can be fabricated by integrating thin metal fiber during the manufacturing stage of textile products or by coating textiles with conductive materials like metal inks, carbon materials, or conductive polymers. The review also discusses how textile electrodes for ECG function via direct skin contact or via a non-contact capacitive coupling. Finally, the current intensive and promising research towards finding textile-based ECG electrodes with better comfort and signal quality in the fields of textile, material, medical and electrical engineering are presented as a perspective.

Abstract:
Sustainable methods of practice within the fashion and textile industry (FTI) often strive to employ a circular economy that aims to eliminate waste through the continual use of resources. Complex problems such as waste, consumption, and overproduction are heavily intertwined; the main aim of this paper is to report on research focused on re-examining the potential of food waste streams as a commercially viable and circular source of raw materials for the FTI. Herein, regenerated protein fibres (RPFs) from food production waste streams rich in protein have been chosen as the main topic of focus. RPFs have a rich and relevant history from a local manufacturing perspective during wartime and post-war clothing rationing (1941–1949) in the UK. RPFs were used to meet civilian needs for wool-based textiles as part of a wider series of ‘make do and mend’ strategies designed to manage the consumption of new textile products. However, RPFs demonstrated inferior quality in terms of durability when compared to wool-based textiles, a significant contributing factor to the consequent commercial phasing out of RPFs. In today’s take–make–waste model, the FTI landscape can be defined by speed, from slow (high-quality materials and construction, long-lasting products) to fast (seasonal, disposable, low-quality materials and construction), the latter infamous for dire environmental impacts. A key objective of this research is to review the association of quality and longevity within the context of a local and circular fashion economy in which textile quality and lifecycle analysis are holistically matched to the longevity of the textile, garment, or product to reduce waste across the supply chain.

Recycling 7, no. 4 (August 12, 2022): 57. http://dx.doi.org/10.3390/recycling7040057.
Abstract:
The fashion industry is becoming one of the largest emitters worldwide due to its high consumption of raw materials, its effluents, and the fact that every garment will eventually contribute to the vast amount of waste being incinerated or accumulating in landfills. Although fiber-to-fiber recycling processes are being developed, the mechanical properties of the textile fibers are typically degraded with each such recycle. Thus, tertiary recycling alternatives where textiles are depolymerized to convert them into valuable products are needed to provide end-of-life alternatives and to achieve circularity in the fashion industry. We have developed a method whereby cotton waste textiles are depolymerized to form a glucose solution, using sulfuric acid as the sole catalyst, with a high yield (>70%). The glucose solution produced in this process has a high concentration (>100 g/L), which reduces the purification cost and makes the process industrially relevant. This method can be applied regardless of the quality of the fibers and could therefore process other cellulosic fibers such as viscose. The glucose produced could subsequently be fermented into butanediol or caprolactam, precursors for the production of synthetic textile fibers, thus retaining the value of the waste textiles within the textile value chain.

Abstract:
The Quality Management System (ISO 9000) compelled manufacturers to consider the environment by reducing the use of raw materials and energy in processes and to adopt clean energy sources. The $2.5 trillion textile sector is the world's second-largest user of water, accounting for 20% of global water waste during the processes. In terms of waste, 85 percent of textiles are disposed of in landfills and only a part of the wastage is recycled. The researcher has worked on additive manufacturing technology using 3D printers for the cleaner production of textile fabrics. It uses less material than the traditional manufacturing methods as it allows to melt/fuse/bind only the required amount of filament to develop the textile products using zero-waste sustainable design strategies. A pilot study was conducted to understand the viability of the use of 3D printing technology for the production of textile material. Based on the feedback, the researcher developed 12 textile samples using different raw materials and 3D printing machines which was further evaluated. It was seen that the most suitable materials to manufacture textiles are thermoplastic polyurethane and thermoplastic polyethylene and the most suitable machine used to manufacture them is FDM and SLA technology. This technology fulfills the Sustainable Development Goal for cleaner production of textile products. It can be concluded that the use of additive manufacturing technology in the textile industry will be a promising production process to meet various requirements especially as the path from an idea to the finished fabric becomes quite easy and fast.

Abstract:
Abstract Electronic-embedded textiles or e-textiles preserve the form factor of typical apparel but have the ability to provide required electrical performance, enabling expanded functionality and comfort to the wearer. However, durable, reliable, and scalable manufacturing of e-textiles has remained one of the major challenges to large-scale development of garment-integrated applications of wearable technology. Moreover, there is a gap in our understanding of the impact of integration of electronics into textiles and challenges involved in manufacturing e-textile garments in mass. In this paper, we present the first manufacturing case study for electronic-embedded garments, to the best of our knowledge. We first developed a sensor-integrated fire-fighter turnout gear coat as an example e-textile product. Next, we performed a pre-production study to investigate the new variables that emerge from the prototyping phase to the production phase. To evaluate the challenges of manufacturing e-textiles in mass as compared to non-electronic garments, we produced 40 pieces each of regular and temperature sensing fire-fighter turnout gear coat liner garments using stitched surface-mount fabrication methods. The study results show that the average manufacturing time and cost to produce a sensor-integrated thermal liner are 3.27 and 3.44 times higher, respectively, than producing a regular thermal liner garment, given that all the materials, labor, and standard sewing methods and machines remain constant. Additionally, we show the impact on requisite worker skills and training and quality assurance methods to produce e-textile garments compared to regular garments. We illustrate high-potential areas where strategic product and production design that leverages existing machines and tools can reduce the impact that embedded technologies have on labor, equipment, and cost. We conclude that the stitched surface-mount manufacturing method could potentially be used as an alternative for manufacturing e-textiles in mass.

European Journal of Research and Development 2, no. 4 (December 31, 2022): 81–89. http://dx.doi.org/10.56038/ejrnd.v2i4.146.
Abstract:
Home textiles have many functions, as well as their aesthetic features for the decoration of homes, that will make people's lives more comfortable. In other words, home textile products are textiles that increase the quality of life and satisfy the daily essentials of individuals for a healthy sleep. It is observed that the home textile industry is becoming exceedingly competitive and products that provide customer satisfaction and offer quality are generally preferred in the global market. The objective of this study is to determine the thermal comfort properties of duvets by making thermal resistance measurements in home textile products and to reveal the effects of properties on sleep quality. In line with this objective, the air and heat permeability of the duvets were measured with the TOG (Thermal Overall Grade) value. As a result of the measurements, the effects of the fiber type and thickness of the filling material in the duvet layers, the fiber type and density of the fabrics and interlining on the TOG values were observed. According to the high or low TOG value, the thermal resistance properties of the duvets were determined with the effect of layer, thickness and material. As a result of this study, the fabric, interlining and filling materials in the duvet layers were standardized according to the TOG values obtained.

Abstract:
Idup Panak woven textil is one of the traditional textil in the Tenganan Pegringsingan Traditional Village. Idup Panak textil as a work of weaving art has its own uniqueness compared to other gringsing fabrics because it is made using leftover threads from other ready-made motifs. Idup Panak textil are starting to increase in existence and the quantity of sales is getting bigger. Of course, it is necessary to strengthen the principles of meaning and value in maintaining the quality of the textile, of course, in order to avoid a decline in cultural understanding. Departing from the problems above, this study aims to strengthen the construction of values and principles contained in the Idup Panak textile. The method used is a qualitative research method using interview techniques, observation and literature in data collection. This study uses symbol theory which will assist in analyzing the symbols contained in the Idup Panak Textil and the Communication Strategy Theory which functions in the development of the Idup Panak Textil so that all forms of principle values contained in the Idup Panak Textil are preserved. The results show that action has begun. duplication of Idup Panak Textil in order to meet consumer demand, this has resulted in craftsmen starting to experience social blindness which only prioritizes quantity and puts aside the meaning of value, it is very necessary to educate and supervise to face increasingly advanced developments bringing this tradition in a positive direction with meaning values that are still maintained .

Abstract:
Cotton is a highly variable natural material that is routinely blended during textile processing to create a uniform product. Harvesting and ginning can introduce some blending before the mill. Blending earlier in the supply chain could produce a more consistent and predictable product. There has been limited research on the benefits of in-field blending of cotton cultivars, especially from a textile perspective. Experiments were conducted over two seasons to determine the economic and performance impacts of in-field blending. The seed of three cultivars with different quality parameters were blended in combinations of two cultivars at 25% increments before planting. Crop maturity, lint yield, fiber quality, and textile processing were evaluated for both years. Some combinations resulted in differences in micronaire, fineness (linear density), and fiber length, which mostly followed the blend rates of the constituent cultivars. Although there were some statistical differences, no functional differences were observed for yield, textile processing, or textile quality. The most significant result was the movement of one set of blends from the base range of micronaire to the premium range. The results showed that infield blending of cultivars could be done without harming quality or resultant textiles, as long as the cultivars are carefully selected for similar seed characteristics and maturation timing. Individual producers will have to determine if the benefits and risks are worthwhile for their specific situation.

Abstract:
Electrocardiography (ECG) is an essential tool in assessing equine health and fitness. However, standard ECG devices are expensive and rely on the use of adhesive electrodes, which may become detached and are associated with reduced ECG quality over time. Smart textile electrodes composed of stainless-steel fibers have previously been shown to be a suitable alternative in horses at rest and during exercise. The objective of this study was to compare ECG quality using a smart textile girth band knit with silver and carbon yarns to standard adhesive silver/silver chloride (Ag/AgCl) electrodes. Simultaneous three-lead ECGs were recorded using a smart textile band and Ag/AgCl electrodes in 22 healthy, mixed-breed horses that were unrestrained in stalls. ECGs were compared using the following quality metrics: Kurtosis (k) value, Kurtosis signal quality index (kSQI), percentage of motion artifacts (%MA), peak signal amplitude, and heart rate (HR). Two-way ANOVA with Tukey’s multiple comparison tests was conducted to compare each metric. No significant differences were found in any of the assessed metrics between the smart textile band and Ag/AgCl electrodes, with the exception of peak amplitude. Kurtosis and kSQI values were excellent for both methods (textile mean k = 21.8 ± 6.1, median kSQI = 0.98 [0.92–1.0]; Ag/AgCl k = 21.2 ± 7.6, kSQI = 0.99 [0.97–1.0]) with <0.5% (<1 min) of the recording being corrupted by MAs for both. This study demonstrates that smart textiles are a practical and reliable alternative to the standard electrodes typically used in ECG monitoring of horses.

Sensors 19, no. 20 (October 12, 2019): 4426. http://dx.doi.org/10.3390/s19204426.
Abstract:
The interconnection between hard electronics and soft textiles remains a noteworthy challenge in regard to the mass production of textile–electronic integrated products such as sensorized garments. The current solutions for this challenge usually have problems with size, flexibility, cost, or complexity of assembly. In this paper, we present a solution with a stretchable and conductive carbon nanotube (CNT)-based paste for screen printing on a textile substrate to produce interconnectors between electronic instrumentation and a sensorized garment. The prototype connectors were evaluated via electrocardiogram (ECG) recordings using a sensorized textile with integrated textile electrodes. The ECG recordings obtained using the connectors were evaluated for signal quality and heart rate detection performance in comparison to ECG recordings obtained with standard pre-gelled Ag/AgCl electrodes and direct cable connection to the ECG amplifier. The results suggest that the ECG recordings obtained with the CNT paste connector are of equivalent quality to those recorded using a silver paste connector or a direct cable and are suitable for the purpose of heart rate detection.

Abstract:
Textiles are necessaries of human life. The fiber content is index of textile quality and how to measure it has important meaning. A method for testing fiber contents in mixture textiles by near infrared spectroscopy (NIR) was researched. The near infrared Spectra of samples in the range of 4000 cm-1 - 10000 cm-1 were obtained. Noise reduction and compression of spectra data was done by wavelet transform (WT). The reconstructed spectral signals were established based on WT and the correction models based on back propagation (BP) neural network were built. Comparisons between the BP neural network models at different analysis scale and the model of partial least square method (PLS) were given. When the structure of neural network is 11-9-2 for cotton/ terylene mixture samples and 21-13-2 for cotton/wool mixture samples, the best accuracy and fastest convergence speed is achieved. Experimental results have shown that this approach by Fourier transform NIR based on the BP neural network to predict the fiber content of textile mixture can satisfy the requirement of quantitative analysis and is also suitable for other fiber contents measurement of mixture textiles.

Abstract:
Purpose: The ultrasonic amplitude method for controlling the surface texture density of textile materials was first studied and used. Design/methodology/approach: For the first time, the surface texture density has been determined. The research was conducted using the ultrasonic method, rather than by mathematical calculations, which made it possible to invent a new approach to contactless quality control of textile materials. In order to identify the functionality of bicomponent textile material, formed from raw materials with opposite hygroscopic properties, two-layer knitted fabrics were chosen to protect the human respiratory organs. As a hydrophilic type of raw material used yarn with composition is as follows – cotton 34%, flax 33%, viscose 33%, and in the function of a hydrophobic raw material, polypropylene multifilament yarn. Using the ultrasonic method, studies of a new type of knitwear were carried out, the values of the surface density of the material were obtained. Products from this composition provide respiratory protection from dust and comfortable work in the area of road repairs up to 8 hours. Findings: The combination of natural and synthetic materials for individual masks allowed them to be used under different operating conditions. The problem of structure and design of materials was resolved through the use of computer technology and computer-aided design of textiles, and the possibility of applying the ultrasonic amplitude method to control the surface density of textile materials was substantiated. During the analysis of the results of experimental studies, it was found necessary to ensure the uniformity of the physical and mechanical properties of textile materials in the production process. Using the ultrasonic method, the thickness gauge was used to determine the surface density of various materials for the manufacture of personal protective equipment for road maintenance workers. Research limitations/implications: The method of measurement has been tested and has no limitations. However, the study was conducted on samples of textile materials that were manufactured in Ukraine and according to patents of authors. Practical implications: Individual masks for the protection of human respiratory organs are recommended for use by road workers and cyclists. Originality/value: The originality of the results of the article is the experimental data of studies on the content of textile materials and the accuracy of measuring their surface density by an ultrasonic contactless device.

Abstract:
Abstract A new technique in textile coloring, namely the ecoprint dyeing technique, has emerged which further proves the development of the textile industry. There are several techniques of ecoprint which are steaming technique, pounding technique and boiling technique. To produce a good eco print color, one must consider the ecoprint coloring technique, the type of textile material used, the type of mordant substance, the mass of the mordant substance, and the length of the coloring process. Mordant alum is more widely used as a fixator because it is easier to obtain and more affordable. Meanwhile, one of the natural coloring substances that can be used as natural dye is Jatropha leaves (Jatropha curcas L.). Researchers then further revealed the use of Jatropha leaves to color the textile because it has the potential to be used as natural fiber-based dyes for textiles. The independent variable used in this study is the ecoprint technique, including steaming (X1), pounding (X2), and boiling (X3). Meanwhile, the dependent variable is the quality of eco prints results with indicators including: colors difference and darkness. The data analysis method used in this research is descriptive and inferential statistics. The dyeing process on cotton cloth using alum fixation treatment and the bottom pounding method resulting the highest color darkness compared to other coloring methods. The bottom pounding method produces the darkest color. Statistical results of ANOVA test showed that there was a significant effect on the test results.

Abstract:
One of the ways to achieve the required level of quality of industrial products and, consequently, to increase the competitiveness of Russian manufacturers is to implement the task of optimising and unifying the nomenclature of products produced by enterprises. However, at present, due to the differences in the classification and coding systems of consumer products at the corresponding stages of its life cycle, there are problems with the unification of the nomenclature of industrial products, including textiles, since textile and light industry enterprises, trade organisations and customs authorities each use their own classification of these types of products. The paper analyses the functional capabilities of the currently existing coding systems for textile products, and also proposes and implements a method for matrix coding of textile products on the range of geosynthetic materials produced. In addition, the possibility of combining matrix coding of products with information about its manufacturer and quality in the framework of a two-dimensional barcode is shown.
