Piribauer, Benjamin, and Andreas Bartl. "Textile recycling processes, state of the art and current developments: A mini review." Waste Management & Research: The Journal for a Sustainable Circular Economy 37, no. 2 (January 11, 2019): 112–19. http://dx.doi.org/10.1177/0734242x18819277.
Abstract:
World fibre production has been rising continuously over last decades and a tremendous increase is expected in the near future. The major portion of fibres goes to the textile industry whose main output streams are apparel and home textiles. With the transformation of these textile products from a basic human need to fashion items, their lifetime before disposal is steadily declining, while at the same time the complexity of their material composition is increasing. As a matter of fact, the amount of disposed items is increasing distinctively and the issue of a proper handling of end-of-life textiles is becoming more important. The objective of this mini review is, first to give a brief overview of the already available textile recycling methods, and subsequently it will discuss innovative developments of new recycling processes in the textile recycling sector. A special focus of this review lies on the emerging field of biochemical fibre recycling processes, which could become a major step on the way to a circular economy in the textile processing chain. Owing to the high selectivity of bio-catalysts, enzymes, these processes could be used to remove a specific fibre material from multi-component textiles. As the complexity of textiles is reduced, the recyclability is increased.

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:
The development of malodour on clothing is a well-known problem with social, economic and ecological consequences. Many people still think malodour is the result of a lack of hygiene, which causes social stigma and embarrassment. Clothing is washed more frequently due to odour formation or even discarded when permastink develops. The malodour formation process is impacted by many variables and processes throughout the textile lifecycle. The contact with the skin with consequent transfer of microorganisms, volatiles and odour precursors leads to the formation of a distinctive textile microbiome and volatilome. The washing and drying processes further shape the textile microbiome and impact malodour formation. These processes are impacted by interindividual differences and fabric type as well. This review describes the current knowledge on the volatilome and microbiome of the skin, textile and washing machine, the multiple factors that determine malodour formation on textiles and points out what information is still missing.

"Flexible Temperature Sensor Integration into E-Textiles Using Different Industrial Yarn Fabrication Processes." Sensors 20, no. 1 (December 21, 2019): 73. http://dx.doi.org/10.3390/s20010073.
Abstract:
Textiles enhanced with thin-film flexible sensors are well-suited for unobtrusive monitoring of skin parameters due to the sensors’ high conformability. These sensors can be damaged if they are attached to the surface of the textile, also affecting the textiles’ aesthetics and feel. We investigate the effect of embedding flexible temperature sensors within textile yarns, which adds a layer of protection to the sensor. Industrial yarn manufacturing techniques including knit braiding, braiding, and double covering were utilised to identify an appropriate incorporation technique. The thermal time constants recorded by all three sensing yarns was <10 s. Simultaneously, effective sensitivity only decreased by a maximum of 14% compared to the uncovered sensor. This is due to the sensor being positioned within the yarn instead of being in direct contact with the measured surface. These sensor yarns were not affected by bending and produced repeatable measurements. The double covering method was observed to have the least impact on the sensors’ performance due to the yarn’s smaller dimensions. Finally, a sensing yarn was incorporated in an armband and used to measure changes in skin temperature. The demonstrated textile integration techniques for flexible sensors using industrial yarn manufacturing processes enable large-scale smart textile fabrication.

Abstract:
The Textile Industry is one of the largest industrial sectors and the fifth largest exporter of the textiles employing 45 million workers in India. The Indian textile industry has changed its ways in the production of finished textiles, Energy is involved in each of stage processing. Thus, this study aims to evaluate the energy efficiency of the processes in the textile industry and identify opportunities for improvement in the process involving raw fabric to the finished textile product. The energy efficiency determination in an industry can be evaluated by the energy consumption of the respective process equipment in an industry which includes the performance evaluation of the textile manufacturing processes. This paper describes the operations in textile manufacturing such as weaving, yarn production, spinning, drying, and also the significance of PAT schemes in energy improvement opportunities for various industries, including the technical improvement studies and also provides the brief description on validating various unit operations and respective parameters that affect the performance of various process equipment such as stenter, heaters, compressors, motors, and other non-production equipment. This review paper also described the impact of PAT cycle 1 in validating the energy intensity of technologies used in textile industries and some important measures required to improve the energy efficiency of a process as this could improve the functioning of the system. The best available techniques in the process has also been discussed in the sections which can be implemented in practice for improving the energy efficiency of the processes.

Herald of Khmelnytskyi National University. Technical sciences 307, no. 2 (May 2, 2022): 153–58. http://dx.doi.org/10.31891/2307-5732-2022-307-2-153-158.
Abstract:
The article analyzes the socio-economic, technological, ecological characteristics of the life cycle of textiles, their impact on the environment and human health. According to the results, the directions of safe manufacture and use of textile products in order to preserve natural resources and human health are proffered. Analysis of socio-economic, technological, ecological characteristics of the life cycle of textile products showed that 45% of textile products can be reused, 30% are suitable for processing into technical textiles, 20% – textile fibers. Only 5% of used textile products are waste that needs to be disposed of. Extending the service life of textiles by 9 months can reduce energy, water and СО2 emissions by up to 30%, which contributes to the preservation of natural resources and human health. Based on the analysis, the following directions of safe manufacture and exploitation of textile products are proffered: – raising awareness of the impact of textile manufacturing on the environment and human health; – regardful use of natural and human resources; – reusing and upcycling of textile products; – recycling of waste materials and products to create new ones; – creation of prerequisites for safe exploitation and cleaning of textile products; – application of technologies of soft cleaning of textile products which reduce expenses of the electricity and natural resources at the same time; – reduction of the use of natural resources and emissions into the environment; – improving ecological and socio-economic indicators throughout the life cycle of textiles. Such recommendations allow manufacturers to improve the environmental safety of production processes, and consumers to buy with more rationality, use less clothing, reducing the generation of textile waste. These, in turn, are important factors that extend the service life of textiles, reduce the ecological impact on the environment and human health.

Abstract:
This paper gives an overview of atmospheric pressure plasma types used in the textile industry and recent developments in plasma treatments of textiles. It investigates the topic of the influence of atmospheric pressure plasma treatment on the surface properties of materials made from natural and synthetic fibers. Through plasma induced physical and chemical reactions occurring in the textile surface layer, significant modifications in micromorphology and reactivity can be achieved. In addition to cleaning, etching, and activation, great efforts have been made in the development of plasma polymerization processes under atmospheric pressure. Utilization of atmospheric pressure plasma technology in the textile industry offers a new perspective on surface modification and functionalization. This paper gives a summary of textile properties achieved using plasma and the underlying processes based on relevant findings obtained from prominent research.

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.

Suciati, F., D. B. Aviantara, Suherman, A. Purnomo, and M. Krauss. "Chemical of concern for raising awareness to Indonesian textile sustainability." IOP Conference Series: Earth and Environmental Science 1201, no. 1 (June 1, 2023): 012006. http://dx.doi.org/10.1088/1755-1315/1201/1/012006.
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.

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:
The development of textile finishing techniques and technologies outside of reports in world-wide publications is also very visible at subsequent fairs. At international fairs, such as ITMA, ATMA and FESPA, machine, equipment and dye manufacturers present new techniques and technologies. The development of chemical fibre processing nowadays goes mainly towards the “ecological optimisation” of technological processes as well as the economics of processes. In this article, the main development directions of the chemical treatment of textiles in the field of the pre-treatment, bleaching, dyeing, printing and finishing of textile products are discussed.

Abstract:
The textile industry is one of the most important polluters of the environment. The linear economic system, which dominates the sector, puts pressure on resources, pollutes and degrades the natural environment and its ecosystems and creates significant negative societal impacts on a local scale, regional and global. Given the multitude of technologies, which are growing exponentially, the complexity of current economic processes and society and the need to respond to growing environmental risk challenges, it is necessary to operationalize the textile sector through convergent solutions: disruptive innovation, circular economy, education for sustainable development. The article outlines the benchmarks of the spatial operational scale for creativity, innovation in the context of the textile field, from fiber to textiles, in the succession of (un)conventional, processing processes, on traditional production chains, finalized by specific activities for clothing production, respectively on multidisciplinary production chains, completed by activities specific to obtaining textile systems.

Abstract:
There is a lack of high correlation and reuse potential among multiple manufacturing data for textiles and apparel. Moreover, the material flow traceability between production workstations is not clear, making it difficult to detect potential production bottlenecks. This paper proposes a knowledge graph embedded time serial data-driven bottleneck analysis of textile and apparel production processes. Firstly, a dynamic information association model is established to organize global manufacturing information, including the static data and time-series data features. Also, a textile-corpus-oriented knowledge extraction model is designed to construct a time-series knowledge graph for textile and apparel production (TKG4TA). Then, a temporal knowledge-driven production process bottleneck prediction model is presented based on manufacturing knowledge in the textile and apparel industry. Of these, textile knowledge is transformed into embeddings using a graph convolutional network (GCN). In turn, the context-associated information features are learned by the long short-term memory (LSTM) to predict the bottlenecks in the textile and apparel production process. Finally, a typical process flow in a shirt manufacturing workshop is used as a case study. It shows that the F1 value of the proposed method for named entity recognition and relationship extraction is up to 80.3%, and 50.6%, respectively. The performance of the proposed model for bottleneck prediction is improved by 8.2% and 14.92% compared to only the use of GCN or LSTM in the mean absolute error. This model may provide a solid foundation for the temporal knowledge-graph-driven bottleneck analysis of shirt manufacturing.

Abstract:
The production of textiles has a strong impact on the environment due to both over-consumption and the practice of production processes requiring the use of substances to manufacture, treat, and dye fabrics. In this context, finding new ways and solutions to transform used textiles into by-products or inputs for production is a trump card for the future of the textile sector. This may be accomplished by developing a circular economy policy, which involves large investments with a payoff only in a medium to long-term perspective. The main aim of the present work is to provide a set of guidelines to guide textile industries in the transition from traditional production processes to a systemic approach in consideration of the circular economy. This could leverage the efficient use of regenerated wool, the reduction (or lack) of waste production, and the management of the end-of-life of the product.

Abstract:
Abstract Modern textile and clothing manufacturers can today use the entire range of conventional CAD/CAM systems together with new computer graphics and Internet-based technologies in order to strengthen their position on the market, building a completely new electronic-business offer. Graphical presentation of textile products and processing, or visualisation, presents a promising technology that can be treated as a potential enrichment of conventional computer aided technologies used today by the majority of advanced producers of textile fabrics, clothing, and other textile products. The article presents the results of research on designing computer software for visualising the fabric dyeing process. The program package produced enables the effective visualisation of two fabric dyeing processes: a Pad-Batch machine line for dyeing flat textiles in open-width state, and an HT overflow dyeing machine for fabric dyeing in rope form. Graphical applications of both dyeing processes can be used for both industrial and educational purposes. In this article, we focus more on presenting the program structure and functionalities for using the software to support the education of textile students.

Abstract:
Polymer based textile composites have gained much attention in recent years and gradually transformed the growth of industries especially automobiles, construction, aerospace and composites. The inclusion of natural polymeric fibres as reinforcement in carbon fibre reinforced composites manufacturing delineates an economic way, enhances their surface, structural and mechanical properties by providing better bonding conditions. Almost all textile-based products are associated with quality, price and consumer’s satisfaction. Therefore, classification of textiles products and fibre reinforced polymer composites is a challenging task. This paper focuses on the classification of various problems in textile processes and fibre reinforced polymer composites by artificial neural networks, genetic algorithm and fuzzy logic. Moreover, their limitations associated with state-of-the-art processes and some relatively new and sequential classification methods are also proposed and discussed in detail in this paper.

Abstract:
Textiles and Apparel (T&A) sector is one of the most significant industrial sectors and plays a major role towards contribution to national economy, employment generation and exports in developing countriesand most essential consumer goods industry. However, textile industry is accused of being one of the most polluting industries. Not only production but consumption of textiles also produces waste. To counter the problem, textile industry has taken many measures for reducing its negative contribution towards environment. One of such measures is textile recycling- the reuse as well as reproduction of fibers from textile waste. Recycling can be done through thermal, material, chemical and mechanical processes. Textile recycling is beneficial for environmental and economic conditions, reducing demand for textile chemicals, requirement of landfill space is reduced, consumption of less energy and reducing of water wastage. Market research, and efforts are needed to increase consumer awareness and to encourage manufacturers to increase the use of recycled textile waste into new products. Fashion consumption and sustainability are often opposing ideas. Fashion consumption is a highly resource-intensive, wasteful practice; and sustainability frowns on wasteful consumption. Sustainability in the fashion business is still an emerging agenda, not yet established, and many authors have recognised the importance of investigating how sustainability could be achieved

Abstract:
The article is devoted to the development of a mathematical model for the analysis of functioning interferonogenic supply chain of textile products. A mathematical model and method of analysis of the functioning of an integrated supply chain of textile products are proposed. A mathematical model contributing to cost reduction in the supply chain of textile products is recommended. The results show that the mathematical model of optimization of placement textile enterprises promotes the decrease of the expenses in the supply chain. The designated model will not only be helpful for managers and enterprises related to textiles, but also for other fields dealing with logistics and supply chains in planning and organization of transport processes.

Abstract:
Biodegradable polymers are currently discussed for applications in different fields and are becoming of increasing interest in textile research. While a plethora of work has been done for PLA in medical textiles, other biodegradable polymers and their textile application fields are studied less often, presumably due to higher costs and fewer market opportunities. However, some are emerging from research to pilot scale, and are already utilized commercially in packaging and other sectors but not, unfortunately, in textiles. The commercialisation of such polymers is fuelled by improved biotechnological production processes, show¬ing that textile applications are increasingly conceivable for the future. Additionally, commonly accepted definitions for biodegradability are probably misleading, if they are used to estimate the environmental burden of waste management or recycling of such materials. In this review, the current state of research in the field of biodegradable polymers for the application in textile materials is presented to identify emerging developments for new textile applications. It was clearly seen that PLA is most dominant in that field, while others facilitate new options in the future. The production costs of raw materials and the current patent situation are also evaluated. A special focus is placed on fibre raw materials, coatings, and additives for clothing and technical textiles. Fibre-reinforced composites are excluded, since polymers applied for the matrix component require very different properties compared to the textile materials. This represents a topic to be discussed separately. As a result, these new biodegradable polymers might serve as interesting coating materials for textiles that seem to sneak on to the textile market, as the patent search for such coating formulations suggests. Moreover, new biodegradable fibrous materials for clothing applications can be suggested, but some material properties must be addressed to render them processable on common textile machines.

Abstract:
The textile industry is under continuous pressure to develop and implement eco-friendly processes that offer high performance, acceptable costs and minimal environmental impact. Water is the processing medium to colour textiles and its use incurs a significant cost in terms of acquisition, purification, heating, rinsing, drying and disposal. In this study we examine the problems and potential solutions associated with water-based colouration, the application of pigment dyeing systems and the effect of fluorocarbon finishes and plasma processing on improving their surface and bulk properties.

Abstract:
Nanotechnology has proven its importance in almost all areas, and textile industry is not an expectation. Several applications of nanotechnology can be extended to attain the performance enhancement of textile manufacturing machines and processes. Using different methods like electro spraying and electro spinning, various materials have been used to increase additional functions in textiles. This treatment is applied to give textiles the desired handle, to make further processing easier and to improve the thermal and antistatic properties. In this manuscript, we have summarized the recent advances made in nanotechnology and the methods of fabricating functional fibers by electrospinning and melt spinning preparation. Applications of the nanotechnology in textile industries are also summarized in this paper with some novel ideas that can be utilized for the future research in this area.

Abstract:
The triboelectric nanogenerators (TENGs) have shown the most significant potential in developing a sustainable power source for wearable technologies. Among the various TENGs devices, the textiles are the most suitable candidates for harvesting biomechanical energy due to their excellent flexibility, biocompatibility, confirmability, and simple fabrication techniques. The advancement in the textile technologies enables a seamless integration of TENG into the clothing and accessories for efficient energy harvesting. Various approaches for developing textile-based TENGs are demonstrated mainly on weaving, knitting and combinations of different textile manufacturing processes. The potential of textile-based TENGs to provide sustainable energy for wearables makes them a promising avenue for future developments in the field of renewable energy technology. This paper provides a critical review of current developments in textile-based triboelectric nanogenerators as a sustainable power source, the effect of textile process parameters and the applications of TENGs for physiological monitoring.

Abstract:
This study aims to provide an overview of the latest research studies on the use of biopolymers in various textile processes, from spinning processes to dyeing and finishing treatment, proposed as a possible solution to reduce the environmental impact of the textile industry. Recently, awareness of various polluting aspects of textile production, based on petroleum derivatives, has grown significantly. Environmental issues resulting from greenhouse gas emissions, and waste accumulation in nature and landfills, have pushed research activities toward more sustainable, low-impact alternatives. Polymers derived from renewable resources and/or with biodegradable characteristics were investigated as follows: (i) as constituent materials in yarn production, in view of their superior ability to be decomposed compared with common synthetic petroleum-derived plastics, positive antibacterial activities, good breathability, and mechanical properties; (ii) in textile finishing to act as biological catalysts; (iii) to impart specific functional properties to treated textiles; (iv) in 3D printing technologies on fabric surfaces to replace traditionally more pollutive dye-based and inkjet printing; and (v) in the implants for the treatment of dye-contaminated water. Finally, current projects led by well-known companies on the development of new materials for the textile market are presented.

Abstract:
This paper highlights the potential of large-area hyperspectral imaging for process and quality control in established manufacturing and modification processes of technical textiles. In particular, it is focused on applications in lamination and impregnation of textiles. In case of lamination, NIR chemical imaging was applied to monitor the thickness of the adhesive layers inside the textile laminates and to detect lamination errors, whereas it was used to monitor the homogeneity of the functional finishes applied by impregnation. In both cases, low application weights ranging from only a few to several tens or hundreds grams per square meter have to be detected, which poses a challenge to the sensitivity of the method.

Abstract:
Effluents from dye and textile industries are highly contaminated and toxic to the environment. High concentration of non-biodegradable compounds contributes to increased biochemical oxygen demand (BOD) and chemical oxygen demand (COD) of the wastewater bodies. Dyes found in wastewater from textile industries are carcinogenic, mutagenic or teratogenic. Biological processes involving certain bacteria, fungi, activated carbon and carbon nanotubes (CNTs) are promising methods for treating the waste water. These methods are either inefficient or ineffective. These complexities necessitates search for new approaches that will offset all the shortcomings of the present solutions to the challenges faced with textile wastewater management. This article reviews the past and recent methods used in the treatment of the textile dye wastewater and the future opportunities for efficient treatment of textiles wastewaters.

Abstract:
Environmental contextMicroplastic fibres (MPFs) released from textiles are routinely found throughout the environment as an indicator of human impacts. The presence of MPFs in industrial wastewater effluents shows that attention should be placed not only on domestic release but also on the upstream processes of textile production. In the context of global MPF release, the ability to target and treat industrial effluents may significantly reduce a potentially major point source. AbstractMicroplastic fibres (MPFs) released from textiles are routinely found throughout the environment indicating human impacts on natural systems. The most common release pathway to the environment investigated are domestic textile laundering, transport through and retention in municipal wastewater treatment plants and subsequent application of processed sludge onto agricultural fields as soil amendment. A less-studied but potentially equally relevant source is releases further upstream in the textile production chain such as industrial wastewater effluents from textile processing mills. In this context, industrial wastewater from a typical textile wet-processing mill in China was sampled to estimate MPF release. Effluent was sampled and MPF fibre number and length were quantified by stereomicroscope. An average of 361.6±24.5 MPFs L−1 was identified in the mill effluent. MPF length was highly variable, yet 92% of all fibres were shorter than 1000µm. Additionally, the sampling strategy was used to identify the optimal volume necessary to adequately subsample the effluent. We found that total fibre counts were linearly correlated with sample volumes between 1 and 10L, but a sampling volume of 5L is suggested for good reproducibility, low standard deviation and ease of working volume. The significant abundance of MPFs in the industrial wastewater effluent emphasises that not only should attention be placed on domestic releases, but the production stage of textiles can also be responsible for MPF pollution. The ability to target and treat industrial effluents may significantly reduce a potentially major point source.

Abstract:
The textile industry uses the electrochemical techniques both in textile processes (such as manufacturing fibers, dyeing processes, and decolorizing fabrics) and in wastewaters treatments (color removal). Electrochemical reduction reactions are mostly used in sulfur and vat dyeing, but in some cases, they are applied to effluents discoloration. However, the main applications of electrochemical treatments in the textile sector are based on oxidation reactions. Most of electrochemical oxidation processes involve indirect reactions which imply the generation of hypochlorite or hydroxyl radical in situ. These electrogenerated species are able to bleach indigo-dyed denim fabrics and to degrade dyes in wastewater in order to achieve the effluent color removal. The aim of this paper is to review the electrochemical techniques applied to textile industry. In particular, they are an efficient method to remove color of textile effluents. The reuse of the discolored effluent is possible, which implies an important saving of salt and water (i.e., by means of the “UVEC Cell”).

Abstract:
In the preforming process, the textile is draped into the geometry of the structural part and afterwards consolidated with resin via injection. For preforming processes non-crimp fabrics (NCFs) have become increasingly popular for cost effective applications. For the realization of automated draping of two-dimensional textiles into three-dimensional complex geometries during the preforming process there is a high advantage for the use of tailored textiles compared to textiles with uniform material properties. Large flat surfaces require a high bending stiffness and low shear stiffness due to high structural stability of the textile and small radii of curvature require a low bending stiffness due to good drapeability of the textile. The bending and the shear stiffness of NCFs with a given layup can be influenced by the manufacturing parameters of the knitting yarn. With tailored NCFs it is possible to adapt the manufacturing parameters of the knitting yarn locally in the production direction to improve drapeability and handling of the textile in the preforming process. To use the high potential of tailored NCFs, the development of the new textile structure has to go hand in hand with the characterization and with the simulation of the draping process. An experimental approach and a modelling approach using a kinematic drape algorithm have been developed to define the local stitching parameters for tailored NCFs dependent on the geometry of the component part.

Abstract:
Textile wet processing is an energy-intensive and water-consuming process. Right from pretreatment to finishing several basic, auxiliary, and specialty chemicals are used during the manufacturing of textiles. There are two main processes, namely sizing and desizing which are mutually responsible for increasing the Biological Oxygen Demand (BOD) and Chemical Oxygen Demand (COD) values of liquid effluent emerging after the pretreatment process. This review describes in detail the types of commercial sizing agents depending on their origin, performance, and environmental profile. The review further throws light on the possibilities of extracting energy-efficient, value-added products from the residual waste and effluent. Such recovery mechanisms can enhance sustainability and bring circularity to textile wet processing.

Abstract:
In the context of the circular economy, materials in scientific development present opportunities for material design processes that begin at a raw state, before being introduced into established processes and applications. The common separation of the scientific development of materials from design intervention results in a lack of methodological approaches enabling designers to inform new processes that respond to new material properties. This paper presents the results of a PhD investigation that led to the development and application of a Material-Driven Textile Design (MDTD) methodology for design research based in the materials science laboratory. It also presents the development of the fabrication of a textile composite with regenerated cellulose obtained from waste textiles, resulting from the MDTD methodology informing novel textile processes. The methods and practice which make up this methodology include distinct phases of exploration, translation and activation, and were developed via three design-led research residencies in materials science laboratories in Europe. The MDTD methodology proposes an approach to design research in a scientific setting that is decoupled from a specific product or application in order to lift disciplinary boundaries for the development of circular material-driven fabrication and finishing processes at the intersection of materials science and design.

Abstract:
The textile industry is global, and most brands export their products to many different markets with different infrastructures, logistics, and regulations. A textile waste recovery system that works in one country may fail in another. European Union legislation (Directive (EU) 2018/851) mandates that post-consumer textile waste must be separately collected in all associated countries. This directive has also stated that, in January 2025, the rate of textile waste recycling in Europe should be increased. Local governments will be under pressure to improve the collection, sorting, and recycling of textiles. Supporting local governments could be part of a more long-term approach to managing high-value textile waste by implementing Extended Producer Responsibility, which would increase the recycling rate of textile companies. This would enable reuse of over 60% of recovered clothes, recycling into fibers of 35%, and only throwing away 5%. Today, most textile waste (85%) is disposed of as solid waste and must be disposed of through municipal or local waste management systems that either landfill or incinerate the waste. To increase reuse and recycling efficiency, textile waste should be collected and sorted according to the relevant input requirements. The dominant form of textile waste sorting is manual sorting. Sorting centers could be a future solution for intensifying the recycling of textile waste. Advances in textile waste management will require digitization processes, which will facilitate the collection, sorting, and recycling of textiles. It is very important that digitization will help to guide used products to recycling and encourage manufacturers to participate in the use and collection of product data. Currently, both the digitization of textile waste management and fiber recycling technologies are at the level of laboratory research and have not been implemented. The aim of this publication is to analyze the state of textile waste management, especially the various forms of recycling that involve a local governments and the textile industry.

Cellulose 28, no. 6 (March 2, 2021): 3869–86. http://dx.doi.org/10.1007/s10570-021-03753-6.
Abstract:
AbstractRecycling of textiles is of importance due to the large amount of waste generated from the increasing consumption and use worldwide. Cotton-rich pre-consumer textiles are considered as potential raw material for production of man-made regenerated fibres, but demands purification from the blends with synthetic fibres as well as the dyes and finishing chemicals. In this study we explore the use of different pre-treatments of pre-consumer textiles to meet specific parameters for production of fibres in the cold NaOH(aq) or cellulose carbamate process. The pre-treatments consisted of different bleaching sequences and were performed on both uncoloured and coloured pre-consumer textiles. For the uncoloured textile, degree of polymerisation and amount of inorganic content was efficiently reduced making the material suitable for both the cold NaOH(aq) and the cellulose carbamate process. In case of the coloured textile, the pre-treatments were able to remove the dye and decrease the inorganic content as well as reduce the degree of polymerisation but only sufficiently enough for production of fibres in the cellulose carbamate process. The work was able to prove a fibre-to-fibre concept while further optimisation of the regeneration steps is expected to improve the mechanical properties of the produced fibres in future studies.

Abstract:
It is known that the dyeing process used in laboratory conditions does not allow taking into account the influence of such parameters as the flow rate of the dye solution, the density when placing the dyed fibers, etc. In this regard, the article considers the use of a plant for dyeing textile materials, including dyeing fibers weighing 1-10 grams. In this regard, the article considers the use of a plant for dyeing textile materials, including dyeing fibers weighing 1-10 grams. The influence of the speed of movement of the dyeing system in the range of 1.1 to 1.8 m/min and the weight of the fiber in the dyeing volume in the range of 27.7-125 kg/m3 on the absorption of dyes from the dye bath was studied. When changing the speed of the flow of the dyeing system in the range of 1.1-1.43 m/min, an increase in the content of the dye on the fiber and an increase in the brightness of the color in the range of 37.5-48.9 are observed. It should be noted that with an increase in the flow rate of the dyeing system over 1.43 m/min, the amount of dye on the fiber decreases the brightness to 41.6. This can be judged from the results of measuring the brightness of the color and the coefficient of unevenness, which amounted to 11.24%. The use of the considered installation for dyeing textile materials in the conditions of dyeing shops of the finishing production of the textile industry will allow you to quickly introduce new dyeing recipes and significantly reduce the time for their practical implementation.

Abstract:
Thin, flat textile roofing offers negligible heat insulation. In warm areas, such roofing membranes are therefore equipped with metallized surfaces to reflect solar heat radiation, thus reducing the warming inside a textile building. Heat reflection effects achieved by metallic coatings are always accompanied by shading effects as the metals are non-transparent for visible light (VIS). Transparent conductive oxides (TCOs) are transparent for VIS and are able to reflect heat radiation in the infrared. TCOs are, e.g., widely used in the display industry. To achieve the perfect coatings needed for electronic devices, these are commonly applied using costly vacuum processes at high temperatures. Vacuum processes, on account of the high costs involved and high processing temperatures, are obstructive for an application involving textiles. Accepting that heat-reflecting textile membranes demand less perfect coatings, a wet chemical approach has been followed here when producing transparent heat-reflecting coatings. Commercially available TCOs were employed as colloidal dispersions or nanopowders to prepare sol–gel-based coating systems. Such coatings were applied to textile membranes as used for architectural textiles using simple coating techniques and at moderate curing temperatures not exceeding 130 °C. The coatings achieved about 90% transmission in the VIS spectrum and reduced near-infrared transmission (at about 2.5 µm) to nearly zero while reflecting up to 25% of that radiation. Up to 35% reflection has been realized in the far infrared, and emissivity values down to ε = 0.5777 have been measured.
