El objetivo de la investigación fue determinar la variación de las características textiles y longitud de fibra al descerdado manual del vellón de vicuña, así como evaluar la influencia del sexo, edad, sitio de muestreo del vellón, y lugar de procedencia de la vicuña sobre las características de calidad de la fibra. El descerdado manual se realizó en 77 muestras de vicuñas provenientes de tres provincias del departamento de Apurímac, Perú. Las características textiles de la fibra antes y después del descerdado fueron evaluadas usando el equipo OFDA 2000 y mediante el análisis de varianza, prueba de t y Tukey (α=0.05). La calidad de fibras descerdada es superior a la fibra no descerdada, debido a la reducción del diámetro medio de fibra (DMF) (-1.68 μm), desviación estándar de DMF (DE) (-0.73) y finura al hilado (FH) (-1.27 μm) y al incremento del porcentaje de fibras <30 µm (FC) (1.12%) y de la curvatura media (CU) (6.75°/mm). En fibra descerdada los juveniles tienen un DMF más fino (12.24 μm) que las adultas (13.01 μm), el DMF del costillar medio es más fino (12.39 μm) respecto a paleta (12.81 μm) y grupa (12.77 μm). Asimismo, se encontró variación de las características textiles (DE, CV, FC, y CU) y longitud de fibra entre los vellones de las tres provincias de Apurímac. En conclusión, el descerdado manual reduce el diámetro medio de fibra y su desviación estándar, y aumenta la curvatura media y el confort de la fibra, mejorando las propiedades de calidad y uniformidad del hilo.

The objective of the current examination is to identify the dynamic relationship between the textile industry and energy intensity. The study evaluates the asymmetric impact of textile manufacturing on energy intensity in leading Asian economies based on textile dominance. China, Indonesia, India, Pakistan, Bangladesh, Malaysia, South Korea, Thailand, Japan and Vietnam are dominant in textile manufacturing. In the present study we used yearly textiles and clothing data from top ten selected Asian textile manufacturing countries from 1990 to 2018. The results of quantile-on-quantile regression (QQ) confirmed that textiles and clothing (T&C) production have a positive and significant impact on energy intensity in all countries. The results further suggested that a low level of T&C production increases the level of energy intensity in all selected countries. On the other hand, the results of Granger causality in quantiles confirm a bidirectional causal relationship between T&C production and energy intensity in all selected countries except Thailand and Japan, where a uni-directional causal connection between textile and clothing manufacturing and energy intensity can also be found. This study recommends that governments and investors need to invest more in green and advanced technologies to reduce the energy intensity in Asian economies.

The fouling of surfaces such as textiles is a major health challenge, and there is a continuous effort to develop materials and processes to overcome it. In consideration of this, this study regards the development of antifouling functional nanoencapsulated finishing for the cotton textile fabric by employing a layer-by-layer dip coating technique. Antifouling textile finishing was formulated by inducing the nanoencapsulation of the antifouling functional group inside the hydrophobic polymeric shell. Cotton fabric was taken as a substrate to incorporate antibacterial functionality by alternatively fabricating multilayers of antifouling polymeric formulation (APF) and polyelectrolyte solution. The surface morphology of nanoencapsulated finished textile fabric was characterized through scanning electron microscopy to confirm the uniform distribution of nanoparticles on the cotton textile fabric. Optical profilometry and atomic force microscopy studies indicated increased surface roughness in the coated textile substrate as compared to the uncoated textile. The surface thickness of the fabricated textile increased with the number of deposited bilayers on the textile substrate. Surface hydrophobicity increased with number of coating bilayers with θ values of x for single layer, up to y for 20 bilayers. The antibacterial activity of the uncoated and layer-by-layer coated finished textile was also evaluated. It was significant and exhibited a significant zone of inhibition against microbial strains Gram-positive S. aureus and Gram-negative E. coli. The bilayer coating exhibited water repellency, hydrophobicity, and antibacterial activity. Thus, the fabricated textile could be highly useful for many industrial and biomedical applications.

Die Umsetzung von Prozessketten zur automatisierten Fertigung von 3D-Preforms im industriell etablierten Stempelumformverfahren ist aufgrund hoher Investitionskosten für kleine und mittlere Unternehmen bisher nicht wirtschaftlich tragbar. Die neuentwickelte Prozesskette wirkt dem entgegen und verspricht, komplexe 3D-Preforms bei geringer Prozesszeit sowohl textil- als auch lastgerecht herzustellen und dabei Ausschussquoten aufgrund von Drapierfehlern sowie den Verschnitt zu senken. Implementing process chains for the automated manufacturing of 3D textile preforms based on the established industrial stamp forming technology is not economical for small- and medium-sized enterprises due to high investment costs for small batch sizes and variable geometries. The new process chain counteracts by manufacturing complex 3D preforms at low processing times, both textile- and load-conform, while reducing scrap rates from draping errors and offcut.

In recent years, new textile materials have been developed through the use of nanotechnology-based tools. The development of textile surfaces with self-cleaning properties has a large combined potential to reduce the environmental impact related to pollution. In this research work, three types of textiles substrates (cotton, Entretela, and polylactic acid (PLA)) were functionalized with titanium dioxide nanoparticles (TiO2) using chemical and mechanical processes (padding). During the functionalization process, two different methods were used, both of which allowed a good fixation of nanoparticles of TiO2on textile substrates. The samples were examined for morphology and for photocatalytic properties under visible light irradiation. A study aimed at evaluating the effect of pH of the aqueous solution of TiO2nanoparticles was performed in order to promote interaction between TiO2and the dye solution rhodamine B (Rh-B). The TiO2nanoparticles were characterized by X-ray diffraction (XRD). The measurement of the zeta potential of the TiO2nanoparticle solution proved to be always positive and have low colloidal stability. Chromatography (HPLC and GC-MS) analyses confirm that oxalic acid is the intermediate compound formed during the photodegradation process.

In the textile industry important step is the development of testing methodology to monitor the quantity of nanoparticles that get into the environment from nanoparticles containing textile materials. In the study analyzed the method based on the use of conductometer for textiles testing with nano-size metal oxides content to determine the persistence of nanoparticles/ions in the water after textile soaking/washing. Compared results acquired in the experiments with nanofibre webs manufactured by electrospinning from pure polyvinyl alcohol (PVA) and PVA/ZnO composite. The nanofibre webs were soaked in distilled water and obtained samples of water tested with conductometer. The results of the experiments confirm that measurements taken with the conductometer are fairly stable and repeatable; the equipment is suitable for measurements in distilled water for nanoparticles/ions detection. The measurements of the solution’s specific electric conductance allows to pinpoint the nanoparticles/ions concentration, but for this purpose, must be created the database that contains the resources needed for the calculations and methodology for sample preparation.

Fibre batteries are pioneering as flexible power solutions because they can be woven into textiles. Textile batteries offer a convenient and seamless way to power future wearable electronics. However, current fibre batteries are only centimetres long because longer fibre batteries are difficult to produce and they are thought to have significantly higher internal resistances that compromise electrochemical performance. Here, we show our discovery that internal resistance of fibre battery has a hyperbolic cotangent function relationship with fibre length, where it firstly decreases before leveling off as length increases. Systematic studies confirm this is true for different fibre batteries. We thus produce metres of high-performing fibre lithium-ion batteries via an optimised industrial process. Our mass-produced fibre batteries had high certified energy density based on the total weight of a lithium-cobalt-oxide/graphite full battery including packaging. Over 80% capacity can be maintained after bending for 100,000 cycles, indicating high flexibility. We show fibre batteries woven into safe and washable textile by industrial rapier loom can wirelessly charge a cellphone or power a health management jacket integrated with fibre sensors and textile display.

Textile materials are an essential part of contemporary architecture, the environment, and urban spaces due to their unique appearance and qualities, as it is now possible to achieve both a structural function and an aesthetic quality with textiles. As colour is one of the most important characteristics of textile material, it is also important to understand the relationships between colour and textile material with different surface qualities. In order to explain the complexity of different textile materials and the appearance of colours, which consequently affects the colour properties, this paper analyses this phenomenon. The presented research analyses the dependence of the reproduction quality and colour appearance on fabrics of different construction and structural characteristics, i.e., the texture of the textile material, printed using digital inkjet technology. The aim of this work is to investigate the influence of various structural features of textiles on the colour appearance of digitally printed textile substrates, to monitor the quality of colour reproduction, and to analyse the behaviour of a reactive dye droplet on textile substrates. Printing of a particular shape was performed using a Dimatix Materials Printer DMP-2831 piezoelectric inkjet device (provided by the J. Stefan Institute, Ljubjana, Slovenia; manufactured by Fujifilm Dimatix Inc., 2230 Martin Avenue, Santa Clara, CA, USA). The behaviour of the ink delivered by the needle of the tensiometer DSA20E, Kruess GmbH (provided by the J. Stefan Institute, Ljubjana, Slovenia; manufactured by Kruess Scientific Instruments (Shanghai) Co., Ltd. Futong Dong Dajie 10 Baoneng Center, Tower B, Room 605 Chaoyang District, Beijing 100102, China), on the surface of the fabric was analysed. The samples were digitally printed on a Mimaki digital printer Tx2-1600 (provided by University of Ljubljana Faculty of Natural Science and Engineering, Slovenia EU; manufactured by Mimaki, 2182-3 Shigeno-Otsu, Tomi-city, Nagano, Japan), with reactive dyes, which were first pretreated in a bath with a specific solution. The statistical method of image analysis and microscopic imaging were used to obtain the characteristics of the porosity, texture, and roughness parameters. All results are presented from colouristic analysis based on the objectification of colour and colour differences. The objective values of the parameters of lightness (L*), chroma (C*), and hue (h°) show the significant influence of the structure and properties of the substrate on colour reproduction, and significant changes were obtained, which were confirmed by the evaluation of the colour differences. The results confirm the influence of the substrate structure on colour properties. Furthermore, it is essential to consider this complexity in the context of environmental colour design when utilising (coloured) textile installations/materials in architecture and urban spaces, i.e., in the environment.

This study employed quantitative method to assess various creative works that utilize Adinkra symbols and find out if theusage of the symbol is in agreement with Hierarchy of Needs Theory. The objectives of the study are to explore the symbolismof Adinkra symbols through literature review and to analyse the relationship between the actual philosophical meanings ofAdinkra symbols and the artist’s philosophy behind the use of these symbols. The sampling method used was Stratifiedsampling and Random sampling. Sixty (60) creative works were stratified into these strata: Sculpture, Graphic design, Jewelryand Textile works. Random sampling was also used to sample 15 creative works from the total number of creative works ineach stratum. The data was collected through “Pinterest” (online visual discovery tool). The study found 53% of Adinkrasymbols properly used in relation to the functions of the product. However, 47% of the Adinkra symbols were not in agreementwith the Maslow’s needs. In addition, most of the adinkra symbols used in textiles and jewelry works are basically for aestheticpurposes irrespective of the meaning of the symbol. The textile products accounted for the highest percentage (55%) of adinkrasymbols that do not conform to Maslow’s Needs.

Due to the late start and low level of modern home textile design in China, there are many problems in the development process, such as insufficient design creativity, serious plagiarism, insufficient differentiation, and lack of national characteristics. The fundamental reason is that China's home textile design education is backward. Through design education, a large number of home textile designers with professional quality have been trained, reshaping the understanding of society and colleges on home textile design, and thus improving the level of domestic textile design.In addition, textile design should also conform to the trend of social development. While improving the level of pattern design, it should integrate more comfortable emerging technology fabrics, and combine fashion with technology, thus promoting the innovative development of home textile design.

Detailed knowledge on natural dyes is important for agronomy and quality control as well as the fastness, stability, and analysis of dyed textiles. Weld (Reseda luteola L.), which is a source of flavone-based yellow dye, is the focus of this study. One aim was to reduce the required amount of dyed textile to ≤50 μg for a successful chromatographic analysis. The second aim was to unambiguously confirm the identity of all weld flavones. By carrying out the extraction of 50 μg dyed wool with 25 μL of solvent and analysis by reversed-phase UHPLC at 345 nm, reproducible chromatographic fingerprints could be obtained with good signal to noise ratios. Ten baseline separated peaks with relative areas ≥1% were separated in 6 min. Through repeated polyamide column chromatography and prepHPLC, the compounds corresponding with the fingerprint peaks were purified from dried weld. Each was unequivocally identified, including the position and configuration of attached sugars, by means of 1D and 2D NMR and high-resolution MS. Apigenin-4′-O-glucoside and luteolin-4′-O-glucoside were additionally identified as two trace flavones co-eluting with other flavone glucosides, the former for the first time in weld. The microextraction might be extended to other used dye plants, thus reducing the required amount of precious historical textiles.

Textile materials can be easily used as a support for the nano-decoration with active particles in order to gain new features such as self-cleaning, antimicrobial efficiency, water repellency, mechanical strength, color change and protection against ultraviolet radiations. In this context, our present research reports the fabrication and characterization (physico-chemical analysis and surface morphology) of cotton fabrics treated with reduced graphene oxide decorated with two types of TiO2 nanoparticles co-doped with 1% iron and nitrogen atoms (TiO2/rGO NPs) and synthesized in different hydrothermal conditions by a simultaneous precipitation of Ti3+ and Fe3+ ions to achieve their uniform distribution or after a sequential precipitation of these two cations for obtaining a higher concentration of iron on the surface of Ti4+ oxyhydroxide. Further, the antimicrobial efficiency of these TiO2/rGO-treated textiles and their influence on human cells were assessed. We demonstrated the successful development of TiO2/rGO coating of cotton fabrics which are harmless for human skin cells and inhibit the growth of Staphylococcus aureus and Enterococcus faecalis. These findings confirm their great potential as novel graphene-based materials for biomedical and photocatalytic applications and this approach could be used for the large-scale fabrication of innovative self-cleaning and antimicrobial textiles.

Human activity recognition has become an attractive research area with the development of on-body wearable sensing technology. Textiles-based sensors have recently been used for activity recognition. With the latest electronic textile technology, sensors can be incorporated into garments so that users can enjoy long-term human motion recording worn comfortably. However, recent empirical findings suggest, surprisingly, that clothing-attached sensors can actually achieve higher activity recognition accuracy than rigid-attached sensors, particularly when predicting from short time windows. This work presents a probabilistic model that explains improved responsiveness and accuracy with fabric sensing from the increased statistical distance between movements recorded. The accuracy of the comfortable fabric-attached sensor can be increased by 67% more than rigid-attached sensors when the window size is 0.5s. Simulated and real human motion capture experiments with several participants confirm the model’s predictions, demonstrating that this counterintuitive effect is accurately captured.

One of the reasons for the low demand for domestic textile fabrics is the incomplete satisfaction of consumers' requirements with regard to the quality and price of products, as well as the insufficient use of the Russian certification system as a source of reliable information (advertising) of quality as a set of consumer properties and safety of manufactured products. The paper tests cotton knitted fabrics with various attachments of synthetic fibers and provides recommendations for choosing a rational scheme for their certification in order to use them for the production of various layers of garments.

Piezoelectric materials have attracted more attention than other materials in the field of textiles. Piezoelectric materials offer advantages as transducers, sensors, and energy-harvesting devices. Commonly, ceramics and quartz are used in such applications. However, polymeric piezoelectric materials have the advantage that they can be converted into any shape and size. In smart textiles, polyvinylidene fluoride (PVDF) and other piezoelectric polymers are used in the form of fibers, filaments, and composites. In this research, PVDF nanofibers were developed and integrated onto a knitted fabric to fabricate a piezoelectric device for human body angle monitoring. Scanning electron microscopy and X-ray diffraction analyses were used to study the morphology and to confirm the beta phase in fibers. The results reveal that the nanofibers made from solutions with high concentration were smooth and defect-free, compared to the fibers obtained from solutions with low concentration, and possess high crystallinity as well. Under high dynamic strain more output voltage is generated than under low dynamic strain. The maximum current density shown by the device is 172.5 nA/cm2. The developed piezoelectric nanofiber sensor was then integrated into a knitted fabric through stitching to be used for angle measurement. With increasing bending angle, the output voltage increased. The promising results show that the textile-based piezoelectric sensor developed in this study has a great potential to be used as an angle measuring wearable device for the human body due to its high current density output and flexibility.

The wireless communication systems are applied in different applications such as computers, mobile phones, satellites and antennas for off-body communication. A lot of efforts were made to have the antennas in a smaller size, flat and with better performance. In the last decade the rigid antennas are replaced with textile in order to be flexible and to be integrated into garments in order to have wearable textile systems. The textile antennas can find use in medical, military and first responders monitoring. The conductivity of the antennas can be achieved by using coated textile materials which are available in the market, conductive threads for embroidery or conductive inks. When using the conductive coated textile it is necessary to cut the patch in the desired pattern but using a simple cutting tool sometimes is not very precise and accurate. Thus in our study we decide to screen print with silver conductive inks on Polyester and Cotton/Polyester substrates. The screen printed antennas are than washed in order to conform that antennas for off-body communication integrated in garments can be easily washed five times.

We report the investigation of temperature-dependent magnetic properties and photocatalytic activity ofCoFe2O4−Fe3O4magnetic nanocomposites (MNCs) synthesized by hydrothermal process. Room-temperature magnetic hysteresis (M-H) loops result enhanced saturation magnetization of 90 emu/g and coercivity (HC) of 530 Oe forCoFe2O4−Fe3O4MNCs. With decreasing temperature to 20 K,HCincreases from 500 Oe to 6800 Oe, and the M-H loops exhibit exchange coupling feature betweenCoFe2O4andFe3O4. Low- and high-temperature-dependent magnetization measurements confirm that the blocking temperature lies above 300 K and the presence of two magnetic phase transitions corresponding toCoFe2O4andFe3O4, respectively. The photocatalytic activity of the MNCs has been examined on the reduction of methyl orange (MO), a colored compound used in dyeing and printing textiles. The observed results suggest that theCoFe2O4−Fe3O4MNCs act as an excellent photocatalyst on the degradation of organic contaminants and degrade 93% of MO in 5 hours of UV irradiation. The photocatalytic activity of MNCs is attributed to remarkably high band gap energy and small particle size. Also, the MNCs with a reproducible photocatalytic activity are well separable from water media by applying external magnetic field and acts as a promising catalyst for the remediation of textile wastewater.

The indigo dyed linen textiles are one of the most popular textiles in most of historical periods in the Egyptian civilization. This study aims to investigate the role of indigo dye in preventing, reducing or inhibiting the deterioration of ancient Egyptian linen textiles. In this study linen textiles were experimentally dyed by indigo dye. Undyed and dyed linen were artificially aged by light, heat, soil and fungi. The change in the physical and chemical properties of the undyed and indigo-dyed linen textiles after being artificially aged were determined by various methods such as tensile strength and elongation, the crystallinity index (CrI) by using X-ray diffraction, the surface morphology by using Scanning Electron Microscope (SEM) and spectrophotometric measurements of the colour were calculated. The results confirm that indigo dye inhibits and reduces the deterioration of linen textiles. These results confirm that indigo dyed linen textiles are more durable than undyed ones. They may explain why archaeologists discover dyed linen textiles in better condition than undyed ones. Also, they explain why the Museums in Egypt have dyed linen textiles in better quality than undyed ones.

Background: Personal health monitoring with wearable electronics has gained momentum in the recent years due to its usage in flexible textile-based sensors/electrodes for recording of physiological vital parameters. Such system provides scope for long term ambulatory ECG measurement and motion tracking applications. The selection /design of textile sensors play a vital role as it has to overcome skin irritations, improve the skin-electrode impedance required for conductivity. The composition of textile materials, shape and size of the textile electrodes contributes significantly towards the conductivity. Objective: To assess the proposed Cardif system for its suitability to introduce in the clinical routine Method: The proposed textile electrodes were designed using knit jersey conductive material. The skin –contact impedance of the proposed textile material, was measured using two electrode impedance method and measurement was done for different age groups by varying the frequency. Results: The measurement results showed that the impedance was decreasing with increasing frequency and was found to be below 1.5Mohm/cm2 in the frequency range of 20Hz to 1KHz for three different age groups. The performance of the CARDIF was assessed using heart rate, RR interval, SNR as well as qualitative assessment through visual inspection and were compared with gel based disposable Ag/AgCl electrodes. Qualitative and quantitative analysis was performed and the various results confirm the proposed textile electrodes for continuous patient monitoring applications.

The permanent anti-mold protection of textile surfaces, particularly those utilized in the manufacture of outdoor sporting goods, is still an issue that requires cutting-edge solutions. This study attempts to obtain antifungal nanocoatings on four selected fabrics used in the production of high-mountain clothing and sleeping bags, and on PET foil as a model substrate, employing the cold plasma technique for this purpose. Three plasma treatment procedures were used to obtain such nanocoatings: plasma-activated graft copolymerization of a biocidal precursor, deposition of a thin-film matrix by plasma-activated graft copolymerization and anchoring biocidal molecules therein, and plasma polymerization of a biocidal precursor. The precursors used represented three important groups of antifungal agents: phenols, amines, and anchored compounds. SEM microscopy and FTIR-ATR spectrometry were used to characterize the produced nanocoatings. For testing antifungal properties, four species of common mold fungi were selected: A. niger, A. fumigatus, A. tenuissima, and P. chrysogenum. It was found that the relatively best nanocoating, both in terms of plasma process performance, durability, and anti-mold activity, is plasma polymerized 2-allylphenol. The obtained results confirm our belief that cold plasma technology is a great tool for modifying the surface of textiles to provide them with antifungal properties.

Purpose The purpose of this paper is to investigate how the firm’s internal factors influence employee engagement (EE), which, in turn, enhances the performance of textile employees. Furthermore, the present study pursues to address the indirect effect of EE on the relationship between the firm’s internal factors and employee performance. Design/methodology/approach Data were taken from 355 participants working in textile mills through a survey approach. Structural equation modeling was run to confirm the proposed model and structural relationships. Findings Results highlight that internal communication and reward and recognition are significantly related to EE, except for work‒life balance. Furthermore, EE has a significant effect on the performance of textile employees. Practical implications The present study helps the textile managers to improve employee performance while focusing on the firm’s internal factors of engagement. Proactive internal communication and reward system will help to bring a competitive edge and achieve the organizational goals. The findings also provide managers the information to reduce the organization interruptions in enhancing EE and performance. Originality/value This study covered the hidden gap in the previous literature on EE and performance, especially in the field of the textile sector by employing Kahn’s theory of engagement.

Purpose The purpose of this paper is to present the determination of human thermal comfort with wearing clothes, with different water vapor permeability. Currently, the predicted mean vote (PMV) equation is widely used to determine thermal sensation scales of human comfort. However, moisture permeability of clothes has been not taken in account where the heat is lost from a human body due to water vapor diffusion through clothes. Design/methodology/approach In this study, the heat loss is derived based on the real structure of textiles, causing water vapor pressure difference between air on skin and ambient air. The PMV equation is modified to differentiate a thermal sensation scale of comfort although patterns of clothes are the same. Interview tests are investigated with wearing clothes from three types of textiles: knitted polyester, coated nylon–spandex, and polyurethane, under various air conditions. Findings The moisture permeabilities of knitted polyester, coated nylon–spandex and polyurethane are 16.57×10−9 kg/m2 s•kPa, 9.15×10−9 kg/m2•s•kPa and 2.99×10−9 kg/m2•s•kPa, respectively. The interviews reveal that most people wearing knitted-polyester clothes have the greatest cold sensations under various air conditions since moisture permeability is the highest, compared to coated nylon–spandex, and polyurethane leather. Correspondingly, the predicted results of the modified PMV equation are close to the actual mean votes of interviewees with a coefficient of determination R2=0.83. On the other hand, the coefficient of determination from the predicted results of the conventional PMV equation is significantly lower than unity, with R2=0.42. Practical implications In practice, this quantitative determination on human thermal comfort gives some concrete recommendations on textile selection of clothes for acceptable satisfaction of thermal comfort under various surrounding conditions of usage. Originality/value The modified PMV equation effectively determines human comfort on a thermal sensation scale due to the moisture permeability of clothes. To make generic conclusion, experimental results of additional three textiles, such as plain weave/lining polyester, knitted spandex, and open structure polyester, are reported. They confirm that the modified PMV equation effectively determines human comfort on a thermal sensation scale due to the moisture permeability of clothes.

This paper discusses colorants found in Tumulus MM, the tomb of King Midas or his father, at Gordion, the capital of the Phrygian kingdom. Chromophores, colorants, and auxiliaries are preserved largely independent of the textiles they once colored. The Tumulus MM textiles are now fragmentary due to the degradation processes that occurred inside the tomb chamber. For DHA 26 (Vienna, Austria, 2007), we discussed a group of golden-yellow fragments from Tumulus MM that appeared to be tabby cloth but were skeletal lattices of goethite, αFeOOH (yellow ochre), as identified by FTIR, with SEM/EDS, XRD with molybdenum Kα radiation, NIR, and Raman spectroscopy. The “dyeing” has been replicated using a patented method; originally it may have involved a controlled redox reaction, based on our preliminary experiments. Amidst the goethite lattices, some skeletal fragments were green, with near-black lines within the yarn spiral, identified as indigo by FTIR at the time. Other masses with colorations of red, orange/brown, and purple with deep red veins did not yield identifiable inorganic coloration profiles with SEM/EDS. A purple fragment (2003-Tx-6 Front) was assayed by ICP-MS for mordants and for bromine, but neither could be found. Recently, direct analysis in real time mass spectrometry (DART-MS) enabled us to successfully detect organic colorants. For one fragment, indoxyl, isatin, indigo, and leuco-indigo were identified. One striated red-to-brown mass (2003-Tx-3) contained alizarin, purpurin, xanthopurpurin, lucidin, and other madder substituents; it also contained indigo/isatin but neither indoxyl nor leuco-indigo. Other beige-brown masses like 2003-Tx-5 sometimes contained alizarin, xanthopurpurin, rubiadin, and lucidin but rarely purpurin or indigo-related compounds. The purple (2003-Tx-6) shared the madder analogues with browner hues. The versatility appears related to that found in Anatolian pile carpets and flat weaves. Our new analyses confirm that the Phrygian textile colorists were indeed superb, versatile dyers.

The industry uses color masterbatch mixing process and spinning for dope dyeing. There are color mending and color passivation appearance problems, and the process is inapplicable to functional apparel textiles. In this study, dyeable modified polypropylene (PP) fabric with disperse dye will be developed. The modified polyester material and PP for compounding processing with a compatibilizer will be used to make chips and the quality engineering method will be applied to analyze the optimum spinning process parameters. The fabric will be used to validate the dye washing fastness and light fastness in order to implement the dyeability of PP modified disperse dye. The optimum processing parameters to develop dyeable PP fiber will be studied. The modified materials are made into fiber by melt spinning, and the fuzzy C means technique is combined with the stem cells algorithm to design and analyze the processing parameters for the quality characteristics of tensile strength and elongation. The optimum fully drawn yarn is made. The tensile strength of the fiber of optimum parameter design is 3.66 g/d, higher than the 3.36 g/d of the pure PP fiber; the elongation is 38.65%, higher than the 36.66% of pure PP fiber, meaning the optimization method could improve the characteristics in melt spinning process, and conform with the standards of the textile industry. The fiber derived from the optimum parameters is woven into fabric for the disperse dyeing test and the validation of washing fastness shows the washing fastness is Level 3–4, meaning that the developed modified PP fabric has good dye-uptake and fastness.

This paper aims to confirm how China's representative industry, the cotton textile industry, was influenced by external transactions before the reform and open door era, and what role it played in the Chinese economy.
In the China’s cotton textile industry, raw cotton showed a significant level of self-sufficiency through domestic cotton cultivation. This result was because the Chinese government effectively implemented a cotton production increase policy through the planned economic system.
In addition, few imports were made because cotton products were produced enough to meet domestic demand. Rather, by exporting cotton products that exceed domestic demand, food and facilities could be imported as export price.
As a result, the China’s cotton textile industry has become a leading export industry. It contributed to economic growth by acquiring foreign currency through the export of cotton products and helping to solve the problem of foreign currency shortage in the early stages of economic development.
Compared to the case of Korea, Korea and China showed different patterns in the external trade of raw cotton and cotton products, but their roles in the economy were similar.
In conclusion, the China’s cotton textile industry increased production by importing raw cotton, which was insufficient through external transactions, and it can be said that it contributed to the development of the cotton textile industry and the development of the Chinese economy by exporting cotton products.

In 1985, a short article of mine on Chibcha textiles in the British Museum (the Bunch collection) appeared in Antiquity (Broadbent 1985). In July of that year, while in Bogotá for the 45th International Congress of Americanists, I had an opportunity to examine a fine new collection of textiles in the Gold Museum (Museo del Oro) from the museum of Pasca, a small town near the southern edge of Chibcha territory. According to Cardale (1986). they are said to come from caves on the Páramo de Pisba. Although my analysis of them was somewhat sketchy, the time available being very limited, they seem to confirm the distinctive features I observed in the Bunch collection. I was allowed to take small samples of three of them for radiocarbon dating at the University of California, Riverside (UCR) dating facility. It therefore seems appropriate to present this short note as a sequel to the previous paper.

Abstract Printing is the process of transferring a specific pattern or design onto the surface of textile fabric. In the printing process, screen printing is one of the fundamental printing methods on textiles and is widely used worldwide. However, screen-printed fabrics have specific properties like fastness, water absorbency, and whiteness index that increase the end-use properties of the printed fabrics. There are several factors that affect the technical characteristics of printed fabrics. This research focuses on an experimental approach to ascertain and confirm the pre-treatment process as one of the most important factors in pigment dye screen-printed fabrics. The main raw material used in this research was 100% cotton fabric with a plain weave structure. The experimental method used in this research involved the pre-treatment (singeing, scouring, and bleaching) process with different recipes and four samples. Screen-printed fabric after printing was tested for its technical properties using standard test methods. The results of a one-way ANOVA (Analysis of Variance) were analysed using MINITAB and Microsoft (MS) Excel software. The results indicate superior fabric technical properties like color fastness to rubbing and washing, coupled with improved water absorbency and excellent whiteness index values of samples printed after bleaching with Hydrogen Peroxide (H2O2). In this research, we conclude that printed fabric after bleaching with H2O2 has the best color fastness, and bleaching with NaOCl is the next one. However, printed fabric has a low fastness property after scouring and singeing.

We have little empirical evidence about the environmentally friendly, intention of owner-managers of small- and medium-sized enterprises (SMEs) in emerging country context despite recent developments of proenvironmental, practices. The main objective of our study is to address this gap by exploring the antecedents of environmentally friendly intentions among SME owner managers in, emerging market context. To achieve this objective, we test our, hypotheses in the textile–clothing industry in Tunisia. The textile–clothing industry represents high ecological risk due to the waste discharged into the environment. Our empirical observations confirm that the reasoned action approach is particularly robust to predict environmentally friendly intentions of SME owner-managers in an emerging market context.

The design and development of a novel route for the preparation of efficient photocatalysts for the treatment of polluted water is an essential need. Due to rapid expansion of pharmaceutical and textile industries, the discharge of drugs and sewage contaminants leads to water contamination. To address these issues, hydrothermally synthesized Ni–Cd–S/rGO nanocomposite with a cauliflower structure was developed. The prepared nanocomposite was studied using advanced characterization techniques to confirm crystal structure, surface morphology, optical studies and material composition in detail. Further, the photodegradation process of textile-based Methylene Blue (MB) and Methyl Orange (MO) dyes using Ni–Cd–S/rGO nanocomposite with desired time interval under natural sunlight was also investigated. The maximum photocatalytic performance of > 90% was achieved for the photocatalyst. The photodegradation rate can be maintained after 5 recycling tests in the presence of MB and MO dyes. The remarkable degradation efficiency, high rate constant and reusability of the Ni–Cd–S/rGO nanocomposite make it an excellent choice for textile effluent treatment.

From the textile manufacturers’ point of view, coarse and medullated fibers are undesirable in the production of fine woolen materials, but highly desirable in the production of textiles and yarns with special effects, especially in carpet production. For sustainability, the entire sheep fleece should be used, including the coarse and medullated fibers. The raw wool must be scoured to obtain clean wool fibers without damage or excessive fiber entanglement, with a certain moisture content, low dirt content and residual grease for further processing, and proper color. In order to remove the impurities in raw wool with maximum efficiency, save energy and minimize the environmental impact, this study investigated the changes in some fiber properties during the scouring process due to the effect of the enzyme complex on coarse wool fibers. The effects were studied through the amount of clean wool fibers and impurities within the fleece, the fiber diameter and color. Conventional and enzyme scoured coarse wool were bleached with an unconventional bleaching agent, percarbonate, and compared to bleaching with hydrogen peroxide to achieve higher whiteness and brilliant color with minimal fiber property changes. The changes after the bleaching process were determined based on the sorption of moisture and dyes and the color parameters. The bio-innovative pretreatment with enzyme complex scouring and percarbonate bleaching resulted in excellent fiber properties even for coarse wool. SEM analysis was performed to confirm these results. Taking into account the sustainability of the process and environmental protection, enzyme complex scouring and percarbonate bleaching are recommended as pretreatment processes for raw coarse wool.

Application of Fenton's Reagent in the Textile Wastewater Treatment Under Industrial Conditions Application of reactive dyes is very popular in textile industry as these dyestuffs are characterized by good fastness properties. Constapel et al in 2009 estimated the production of this type of dyes for over 140,000 Mg/year. The reactive dyes are mostly (50%) employed for coloration of cellulosic fibers, however they can also be applied on wool and nylon. Unfortunately, they possess a low degree of fixation (50÷90%), since the functional groups also bond to water, creating hydrolysis and the excess of dyes applied cause a colored pollution of aqueous environment. Moreover, dyeing process requires the use of: electrolytes in the form of aqueous solutions of NaCl or Na2SO4 in the concentration up to 100 g/dm3, alkaline environment (pH > 10) and textile auxiliary agents (including detergents). Therefore, the wastewater generated during the reactive dyeing processes is characterized by high salinity, pH value and color, and due to low value of the BOD5/COD ratio are nonbiodegradable. The successful methods of textile wastewater treatment could be Advanced Oxidation Processes (AOPs), amongst which the Fenton reagent seems to be most promising as it is the cheapest and easy in use. Based on the newest literature survey it was found that many successful tests with Fenton reaction were performed mainly in decolorization. However, not enough attention was devoted to decolorization of real industrial wastewater containing dyes, detergents and salts NaCl, or Na2SO4. The experiments carried out in a laboratory scale were focused on the impact of NaCl and textile auxiliary agent (liquid dispersing and sequestering agent) on an inhibition of decolorization process by Fenton's reagent. The objects of the investigation were synthetic mixtures simulating the composition of real textile wastewater as well as the real industrial wastewater generated in the reactive dyeing. The inhibition of the Fenton decolorization in the presence of NaCl and liquid dispersing and sequestering agent was demonstrated. Additional experiments using pulse radiolysis were carried out in order to confirm the inhibition of chloride in the decolorization process.

An electrocardiograph records the periodic voltage generated by the heart over time. There is growing demand to continuously monitor the ECG for proactive health care and human performance optimization. To meet this demand, new conductive textile electrodes are being developed which offer an attractive alternative to adhesive gel electrodes but they come with their own challenges. The key challenge with textile electrodes is that the relationship between the manufacturing parameters and the ECG measurement is not well understood, making design an iterative process without the ability to prospectively develop woven electrodes with optimized performance. Here we address this challenge by applying the traditional skin−electrode interface circuit model to woven electrodes by constructing a parameterized model of the ECG system. Then the unknown parameters of the system are solved for with an iterative MATLAB optimizer using measured data captured with the woven electrodes. The results of this novel analysis confirm that yarn conductivity and total conductive area reduce skin electrode impedance. The results also indicate that electrode skin pressure and moisture require further investigation. By closing this gap in development, textile electrodes can be better designed and manufactured to meet the demands of long−term ECG capture.

Strengthening of reinforced concrete elements can be carried out using a variety of materials and techniques. One of such materials is textile reinforced concrete (TRC). This material consists of a matrix, usually made of mortar, and textile as reinforcement. This study aims to produce mortar that meets the characteristic of a TRC matrix with respect to an adequate bond strength. The type of mortar developed in this study was fibre reinforced polyvinyl acetate (PVA) modified mortar. The bond strength of this material to the parent concrete was tested by the slant shear method. The results indicate that the amount of PVA content affects the magnitude of the bond strength. The higher the PVA content, the higher the bond strength. The results also confirm that the relationship between the bond strengths and their corresponding compressive strengths tends to be linear.

This paper addresses the design, simulation, manufacturing, and experimental test of textile dipole antennas based on advanced embroidery techniques. The proposed dipoles are intended to operate at the 2.45 GHz industrial scientific and medical radio band for wireless body area network applications. Two medium stitch density embroidery patterns have been studied, satin fill and contour fill, implemented according to the ISO 4915:1991 301 stitch type standard. The impact and viability of these embroidery techniques over the dipole performance in cotton and felt textile substrates are reported. Test results confirm notable antenna parameter results in terms of return loss, radiation pattern, realized gain, and efficiency. In particular, contour pattern has been revealed as the best embroidery manufacturing technique in terms of quality factor and losses, whereas the satin pattern fits the resonance frequency of the antenna with a higher degree of accuracy.

Purpose The purpose of this paper is to propose a model to measure maturity in value co-creation practices and to evaluate its relationship with the market performance of textile companies. Design/methodology/approach The data were obtained through quantitative research with 100 companies of the Brazilian textile sector. A structural equation modeling was performed to verify the relationship between the constructs of the proposed model. Findings The results confirm the proposed model and show that, in addition to a direct impact, the relationship between the maturity of value co-creation practices and market performance also occurs indirectly, by meeting customer expectations. Value co-creation processes can meet customer expectations, leading the company to better market performance. Originality/value A model for assessing the maturity of value co-creation practices enables companies to diagnose their current situation, thereby supporting them in managing these practices and leading to better market performance.

The article proposes a creative method for reducing textile waste from the sewing industry. A street fashion collection of denim clothing has been created. A combination of three approaches was used: the concept of a capsule wardrobe when selecting the types and styles of clothing in the collection; upcycling as an idea for reusing sewing products; a moulage draping method in developing patterns of the garment. To confirm the results, physical samples of the products were sewed. The proposed approach develops the creative thinking of the designer and individual skills of the clothing pattern maker. The anti-consumer attitude of clothing customers to the planet’s resources is being nurtured. The effect is also enhanced by the focus on denim products, whose production is one of the largest in the textile industry. The approach opens up a market niche with the ability to set up a small business online.
