Stab-resistant clothing has been used for centuries by soldiers. Today, it is also used by policemen and other people in dangerous jobs or situations. While chain-mail or metal inserts in protective vests are heavy and uncomfortable, lightweight and bendable alternatives are currently the subject of investigation. Special textile fabrics offer a certain level of stab-resistance that can be improved by different coatings. In this study, we investigated composites of different flexible 3D printing materials, used for the fused deposition modelling (FDM) technique, on woven fabrics. Besides the adhesion between both parts of these composites, the quasi-static stab-resistant properties were investigated and compared with those of pure textile fabrics and 3D prints, respectively.

Textile wastewater, which consist of a complex mixture of synthetic dyes and other organic and inorganic compounds derived from various wet chemical textile processes, can have a harmful effect on the environment; therefore, it must be properly treated before being discharged into municipal wastewater treatment plants and natural water bodies. In this scientific review, the main physical, chemical and biological processes for the removal of dyes from textile wastewater are presented, focusing on photocatalysis, which is a promising advanced oxidation process. The mechanism of photocatalysis is described and the methods used to determine the efficiency of photocatalytic degradation of dyes are presented. Recent studies involving single photocatalytic treatments of real textile wastewaters in the presence of TiO2 and ZnO as catalysts are presented. The advantages of combined processes of photocatalysis in conjunction with other chemical, physical and biological treatments to increase the efficiency of wastewater treatment are discussed. Accordingly, photocatalysis combined with H2O2, photocatalytic ozonation, a hybrid system of photocatalysis and membrane filtration, and coupled photocatalytic-biological processes are described.

Knot configurations serve as the foundation for postoperative tissue repair. Loosening surgical knots during or after tying might lead to an unsuccessful suture and compromise the outcome. This investigation was carried out to study the mechanical properties of knotted silk sutures that are made from braided structures with three different diameters. A maximum tensile strength (33.24 N) and minimum breaking elongation (15%) of dry suture, maximum tensile strength (22.6 N) and minimum breaking elongation (13.6%) of wet suture were achieved with five throws and a diameter of 0.3 mm with surgeon’s square knot.

3D printing on textiles has great potential to influence developments in various industries. It enables the production of new, potentially personalised products in areas such as technical textiles, protective clothing, medical products, fashion, textile and interior design. 3D printing can also contribute to waste-free production processes. In the method of 3D printing on textiles, the material is applied directly to the textile substrate to create 3D objects, patterns or designs on the surface. The fused deposition modelling (FDM) technology, where thermoplastic filaments are extruded and deposited in thin layers based on a 3D model, is widely used for this purpose. A precise control of factors such as temperature and speed is essential in FDM to regulate the flow of polymer material during the printing process. The most commonly used polymer for 3D printing on textiles using FDM is polylactic acid (PLA). Acrylonitrile butadiene styrene (ABS) is another widely used material, known for its low shrinkage rate and high printing accuracy, while thermoplastic polyurethane (TPU) is used due to its exceptional mechanical properties, e.g. tensile strength, flexibility, durability and corrosion resistance. Good adhesion between 3D printed objects and the textile surface is essential for the production of quality products. Adhesion depends on various factors, e.g. textile properties, printing parameters and the type of polymer used. The composition of the woven fabric, including the areal density, warp and weft density, yarn count, fabric thickness and weave pattern, significantly affects the adhesion strength of the 3D printed polymer. When considering double weaves, which allow different materials in the upper and lower layers, better adhesion properties are found than at single weaves. A cross-sectional analysis revealed that the polymer penetrates deeper into a double-woven fabric, resulting in improved adhesion. In general, the study highlights the advantages of double weaves for 3D printing applications on textiles.

The aim of the study was to analyse the impact of various consumer attributes on the fast fashion consumption pattern. The effect of consumer age, family income and family size on the percentage of monthly income spent on clothing and percentage of monthly clothing consumption spent on fast fashion by consumers in NCR (National Capital Region) of India was studied in this research. Causal research was employed in this study. Correlations among the variables were established using the response surface methodology (Box-Behnken experimental design) to understand whether the impact is significant or not. Control factors, studied at 3 levels of variation, were age, monthly family income and family size. The responses for the experiment were the percentage of monthly income (per person) spent on clothing and the percentage of monthly clothing consumption spent on fast fashion. The study revealed that age and monthly family income have a strong influence on the percentage of monthly income spent on clothing, while family size has a negligible or no effect on the percentage of monthly income spent on clothing. It was also found that age, monthly family income and family size have a strong influence on the percentage of monthly clothing consumption spent on fast fashion. The demand for fast fashion and clothing is rising at a very high rate, which has made it hard for retail brands and apparel manufacturers to meet the consumer expectations. The analysis of consumer behaviour provides the advantage to fashion brands in anticipating and meeting consumer demands in a more efficient manner to create brand loyalty.

The use of nanomaterials to functionalise textiles offers new opportunities for chemical modification of textile fibres’ surfaces to achieve multifunctional protective properties. In this study, novel coatings were tailored on cotton fabric by embedding a mixture of TiO2 and ZnO nanoparticles (NPs) of different molar ratios into a chitosan polymer matrix. The excitation energies of the TiO2+ZnO composites generated in the coatings ranged from 3.20 eV to 3.25 eV, indicating that the photocatalytic performance of the functionalised cotton was driven by UV light. The presence of TiO2+ZnO composites increased the UV protection factor (UPF) of the cotton fabric from 4.2 for the untreated sample to 15–21 for the functionalised samples. The UPF values of the coatings slightly decreased after repeated washing. The ZnO in the TiO2+ZnO composites conferred biocidal activity to the coatings, which were resistant to washing at higher ZnO concentrations. In addition, the TiO2 in the TiO2+ZnO composites was responsible for the enhanced photocatalytic self-cleaning of the functionalised cotton, which was observed during the initial period of illumination at lower ZnO concentrations in the composite. The main advantage of these TiO2+ZnO composite coatings is their multifunctionality, which cannot be provided by single-component TiO2 or ZnO coatings. Moreover, these coatings have wide-ranging practical applications, as they were composed of commercially available nanomaterials and were applied using conventional pad–dry–cure equipment.
利用纳米材料功能化纺织品，为纺织纤维表面的化学改性提供了新的机会，从而实现多功能防护性能。在本研究中，通过将不同摩尔比的TiO2和ZnO纳米粒子(NPs)的混合物包埋在壳聚糖聚合物基体中，在棉织物上定制了新型涂层。TiO2+ZnO复合材料的激发能在3.20 eV ~ 3.25 eV之间，表明功能化棉的光催化性能是由紫外光驱动的。TiO2+ZnO复合材料的存在使棉织物的UV防护系数(UPF)从未处理样品的4.2提高到功能化样品的15-21。反复洗涤后，涂层的UPF值略有下降。TiO2+ZnO复合材料中的氧化锌使涂层具有良好的杀菌活性，耐高浓度氧化锌的洗涤。此外，TiO2+ZnO复合材料中的TiO2负责增强功能化棉花的光催化自清洁，这是在复合材料中较低ZnO浓度的初始照明期间观察到的。这些TiO2+ZnO复合涂层的主要优点是其多功能性，这是单组分TiO2或ZnO涂层所不能提供的。此外，这些涂层具有广泛的实际应用，因为它们由市售的纳米材料组成，并使用传统的垫干固化设备进行应用。

Titanium dioxide exhibits photocatalytic properties under ultraviolet (UV) irradiation. In this study, an environmentally friendly, fast and efficient technique for bleaching cotton fabrics is presented, utilising the photocatalytic property of TiO2. Raw cotton fabric samples were treated with TiO2-containing and TiO2-free treatment solutions (hydrogen peroxide and sodium hydroxide) under UV irradiation in order to bleach the samples. The results showed that cotton fabrics treated with TiO2 were bleached satisfactorily without severe strength loss.

Using the exhaustion-pad-dry-rinse method, chitosan was applied to alkaline-scoured and bleached cotton yarns in a solution with concentrations ranging from 0.2–1% to achieve good antimicrobial activity against the bacteria Escherichia coli (Gram-negative) and Staphylococcus aureus (Gram-positive). Studied samples were also assessed by measuring the amount of introduced chitosan, amount of accessible amino groups, mechanical properties, whiteness index and the b* colour coordinate. Alkaline-scoured and bleached cotton yarns treated with all concentrations of the chitosan solution showed good antimicrobial activity against Escherichia coli and Staphylococcus aureus. Better antimicrobial activity was achieved against Escherichia coli. Increasing the concentration of chitosan solution deteriorated the mechanical properties of chitosan-treated cotton yarns. The optimal concentration of chitosan solution incorporated in the exhaustion phase to obtain chitosan-treated yarns with good antimicrobial activity and mechanical properties was 0.6%. The best antimicrobial treatment should minimise potential economic costs while providing functionality.

The textile industry, where clothing industry has an important share, is one of the most polluting industries in the world, wherefore clothing consumption has a significant impact on the environment. The consumption of clothing has been increasing quickly along with the growth of the middle classes in developing nations and the fast-fashion business model. At the same time, consumers are becoming more and more aware of the importance of sustainability, and they have been changing their consumer behaviour accordingly. In this study, we focused our attention on awareness of the environmental impact of clothing production and consumption from the point of view of consumer knowledge, linked to different generations, marital statuses, living environments, family income and type of purchasing store. The study reveals a high-level consumer-evaluated knowledge regarding the effects of clothing production and consumption, but also still the purchasing preference in fast fashion stores.

The sensitivity of chitosan to environmental conditions and processing conditions can stress its structure and cause degradation of this polymer on various application carriers. The stability of chitosan in a designed textile structure of standard polyester fabric with chitosan was analysed in a multiple washing process with a standard detergent by studying the properties before and after 10 washing cycles. The chitosan was coated on standard and alkali treated polyester fabrics. Washing was performed with an ECE A reference detergent at 60 °C according to the Standard protocol HRN EN ISO 6330 in 10 cycles. The washing stability of chitosan onto polyester fabrics was monitored by a staining test, zeta potential, breaking force, breaking elongation, pilling propensity, touch, whiteness, moisture transport, antimicrobial activity and morphological features. The staining test confirmed the wash stability of chitosan coated on alkali hydrolised polyester fabrics, while the chitosan coated on standard polyester fabric disappeared. Zeta potential proved to be the significant parameter for determining chitosan` stability. The tensile properties of fabric samples were harmonised with other characterisation parameters. Coating of polyester fabric with chitosan increased the elasticity of all samples. The antimicrobial activity of polyester fabrics coated with chitosan against Staphylococcus aureus was reduced by 20% after 10 washing cycles. All the characterisation parameters proved that polyester fabric as a chitosan carrier should be surface modified for designing a stable bioactive textile structure of chitosan and polyester.
壳聚糖对环境条件和加工条件的敏感性会影响其结构，并导致其在各种应用载体上的降解。通过研究10次洗涤前后的性能，用标准洗涤剂多次洗涤，分析了壳聚糖在设计的标准涤纶织物结构中的稳定性。将壳聚糖涂覆在标准和碱处理的涤纶织物上。根据标准方案HRN EN ISO 6330，用ECE A参考洗涤剂在60°C下进行10次洗涤。通过染色试验、zeta电位、断裂力、断裂伸长率、起球倾向、触感、白度、水分输送、抗菌活性和形态等指标监测壳聚糖在涤纶织物上的洗涤稳定性。染色试验证实了涂覆在碱水解聚酯织物上的壳聚糖的洗涤稳定性，而涂覆在标准聚酯织物上的壳聚糖则消失。Zeta电位是决定壳聚糖稳定性的重要参数。织物样品的拉伸性能与其他表征参数一致。用壳聚糖对涤纶织物进行涂层处理，提高了所有样品的弹性。经壳聚糖涂层处理的涤纶织物经过10次洗涤后，对金黄色葡萄球菌的抗菌活性降低了20%。所有的表征参数都表明，作为壳聚糖载体的聚酯织物需要进行表面改性，以设计稳定的壳聚糖和聚酯生物活性织物结构。

The stability of chitosan in a designed textile structure of standard polyester fabric with chitosan was analysed in a multiple washing process with a standard detergent by studying the properties before and after 10 washing cycles. The chitosan was coated on standard and alkali treated polyester fabrics. Washing was performed with an ECE A reference detergent at 60 °C according to the Standard protocol HRN EN ISO 6330 in 10 cycles. The washing stability of chitosan onto polyester fabrics was monitored by a staining test, zeta potential, breaking force, breaking elongation, pilling propensity, touch, whiteness, moisture transport, antimicrobial activity and morphological features. The staining test confirmed the wash stability of chitosan coated on alkali hydrolised polyester fabrics, while the chitosan coated on standard polyester fabric disappeared. Zeta potential proved to be the significant parameter for determining chitosan` stability. The tensile properties of fabric samples were harmonised with other characterisation parameters. Coating of polyester fabric with chitosan increased the elasticity of all samples. The antimicrobial activity of polyester fabrics coated with chitosan against Staphylococcus aureus was reduced by 20% after 10 washing cycles. All the characterisation parameters proved that polyester fabric as a chitosan carrier should be surface modified for designing a stable bioactive textile structure of chitosan and polyester.","PeriodicalId":22555,"journal":{"name":"TEKSTILEC","volume":" ","pages":""},"PeriodicalIF":0.7,"publicationDate":"2023-06-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48281300","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
