Abstract As lightweight and comfortable wool products have become the mainstream of the market, the surface treatment technology of wool fiber has been widely observed. Here, we treated wool fibers by ultrasonic bath and oxidation in a composite method that was better able to improve the wetting properties of wool fiber. Using this approach, we investigated the main factors influencing the effect of treatment and established the regression equations of multiple indices on processing conditions; after testing and optimization, the optimum technological parameters were obtained and experimentally verified. In addition, test results revealed that the ultrasonic-oxidation treatment in the optimum process led to the disulfide bonds (S-S) of wool fiber breaking and being oxidized, but showed less effect on the fiber's supramolecular structure; the wool fiber surface became smoother and more uniform, which resulted in a greatly increased wettability; there was a remarkable decrease in contact angle, and the rate of moisture absorption and desorption was enhanced in response to optimal treatment. These findings are significant for the potential industrial application of wool fiber as a moisture-absorbing material in textile products.

Abstract In recent years, with the increase in global awareness of environmental problems, the term “sustainability” became more important for apparel manufacturers and consumers. Therefore, recycling of wastes plays a significant role in environmental sustainability by converting the wastes into raw materials. This study focused on recycled cotton-included fabrics, to evaluate the effect of these fabrics on thermal comfort properties. In this context, first, the 45% recycled cotton/55% polyester blended yarns and 50% virgin cotton/50% blended yarns were obtained. Afterwards, single jersey and rib-structured fabrics were knitted using these yarns. The thermal comfort tests were performed on the fabrics and four long sleeve rounded neck shirts then were manufactured using these fabrics to test by the thermal manikin method. Results showed that the yarns including recycled cotton led to a decrease in the values in air permeability of the fabrics and in the effective clothing insulation of the garments. In contrast, it was observed that, including recycled cotton increased the thermal resistance values of the fabrics.

Abstract Nowadays, intensive rivalry forces enterprises and brands to strive for differentiation. Use of marketing strategies, which can allure the consumers, effectively is one of the ways of differing oneself from one's rivals. Sensory marketing strategy, which affects the buying behavior and perception of consumers by alluring their senses, is one the marketing strategies whose importance and use have increased in recent years. This strategy also has been intensively used by enterprises that produce and market clothing products, which are one of the basic needs of consumers. In this context, this research study aims to analyze the effects of sensory marketing on clothing-buying behavior. The research aims to reveal how consumers in Turkey, which is one of the leading global clothing exporters and at the same time which is one of the significant markets, are affected by sensory marketing factors during the clothing purchase process. In accordance with the aim of the research, a survey was conducted of consumers who live in the three biggest cities of Turkey and whose ages are 18 and over. The data, which were obtained from field research, were analyzed statistically and suggestions are made to enterprises and brands that produce clothing products and/or market clothing products, on the basis of the study's findings.

Abstract Transport of liquid water is one of the basic producer requirements to ensure the suitable physiological comfort of drivers. This paper deals with the investigation of car seat covers’ efficiency from the point of view of their moisture management. Two methods were used for the evaluation of moisture transport in the car seat cover structures. Both of them use a thermography system for water transport detection. The first method evaluates dynamic water spreading in cross-section in the frontal plane; the second one examines horizontally dynamic spreading of liquid drops on the upper face of the sample. The tested materials were designed to understand the role of the middle layer of textile sandwich car seats in their moisture management behavior. The same PES woven structure in the top layer was used for all tested samples. Knitted spacer fabric (3D spacer fabric), polyurethane foam, and nonwoven were used as padding in the middle layer in car seat covers. In summary, the distribution and transport of liquid moisture in a sandwich structure are fundamentally affected by the middle layer of composite, especially by material composition and the value of porosity. The best results were shown in 3D spacer fabric for car seat covers.

Abstract Among the different nanostructures that have been demonstrated as promising materials for various applications, three–dimensional (3D) nanostructures have attracted significant attention as building blocks for constructing high-performance nanodevices because of their unusual mechanical, electrical, thermal, optical, and magnetic properties arising from their novel size effects and abundant active catalytic/reactive sites due to the high specific surface area. Considerable research efforts have been devoted to designing, fabricating, and evaluating 3D nanostructures for applications, including structural composites, electronics, photonics, biomedical engineering, and energy. This review provides an overview of the nanofabrication strategies that have been developed to fabricate 3D functional architectures with exquisite control over their morphology at the nanoscale. The pros and cons of the typical synthetic methods and experimental protocols are reviewed and outlined. Future challenges of fabrication of 3D nanostructured materials are also discussed to further advance current nanoscience and nanotechnology.

Abstract The demand for polyester fiber is increasing gradually day by day. Because of its good strength, low manufacturing cost, and ease of modification, polyester fiber has distinct characteristics, whereas cotton is well known for its comfort. Blending these fibers improves the performance of yarns. In this study, cotton/polyester was blended in different ratios to evaluate yarn performance. Three groups of yarn: rigid, core, and dual-core-spun, have been produced to examine the yarn’s performance. From the study, it has been found that increasing the polyester blend ratio increases the yarn strength and elongation but decreases the yarn unevenness and imperfections. Among the group, having more core components decreases yarn strength, unevenness, and imperfection but increases elongation. From the statistical analysis, except strength, all other properties have good interaction on yarn type and blending ratio. Pearson correlation also indicated that elongation and hairiness have a good correlation with yarn type where, except for hairiness, all other properties have shown a strong positive correlation on blending ratio.

Abstract Reinforcement of fibers was carried out by adding carbon black (CB), and hydroxylated and carboxylated carbon nanotubes (CNTs) into electrospinning solution containing doped polyaniline (CSA-PANI) and polyacrylonitrile (PAN). CB/CSA-PANI/PAN and CNT/CSA-PANI/PAN electrospun nanofiber composite membrane was formed in high-voltage electric field. The CSA-PANI/CB/PAN fiber membrane was found to be more brittle than the MWCNTs/CSA-PANI/PAN fiber membrane. The average diameter of the CSA-PANI/CB/PAN nanofibers increased with CB addition, while the average diameter of CNT-added MWCNTs/CSA-PANI/PAN nanofibers decreased with increasing CNT concentrations. Upon greater CB and CNT addition, agglomeration occurred, and the surface of the fibers was raised slightly. The fracture strength of the nanofiber membrane was greatly improved with 1% added CB but then decreased upon further CB addition. Upon addition of CNTs, the fracture strength of the nanofiber membrane first increased and then decreased, and the addition of carboxylated CNTs was more advantageous for improving the fracture strength of the fiber membrane. The electromagnetic shielding performance of the fiber membranes was essentially the same for different radiation frequencies. Upon addition of CB and CNTs, the electromagnetic shielding performance of the fiber first increased and then decreased, with a more pronounced decrease obtained by the addition of CB.

Abstract A study of polyvinylchloride-coated woven polyester fabric welding potential was conducted using continuous ultrasonic welding machines. The effect of cooling air, anvil wheel status, anvil wheel width, material surface contact, and welding gap on seam strength was studied. Three main welding parameters with different levels were selected based on 5 and 10 mm welding widths using old and new anvil wheels with and without cooling air. A lapped type of seam was applied under full factorial design. A microstructure was captured to examine the formation of welding joints, and seam tensile properties were determined. Comparative analysis of comparable welding parameters was analyzed for a gap against pressure and amplitude against power. The actual weld phenomenon was also analyzed based on the recorded machine parameters. The results showed that auxiliary parameters had a significant effect on seam strength. A microscopic image of a welded seam indicated that cooling air reduced the number and size of holes produced. Weld seam with controlled pressure or power provided higher seam strength than that of the controlled gap or amplitude. The actual phenomenon of welding parameters was important to evaluate weld seam quality, whereby the obtained results indicated good quality at lower power and pressure.

Abstract This article presents a method for modeling the material characteristics of synthetic fabrics based on static tensile test results with consideration of material orthotropy. Material characteristics were determined for fabrics under load at three different angles in relation to their orthotropy. The fabrics examined were the following: polyester fabrics Bratex and Ortalion, cotton fabric with nylon and elastin fabric (poplin), and Gore-Tex membrane fabric. Considering the material mechanical characteristics, the differences were in grammage, maximum strain, and tensile strength. The study allowed us to determine the nonlinear elastic dependency between strain and stress. Test results were implemented within the Abaqus/Explicit framework for the purpose of performance of verification simulations. The correlation between simulated and experimental results was established. A high degree of similarity allows us to classify the obtained material model as usable in simulation work.
