Sportswear, the clothing including footwear, worn during sports or physical exercise, has an increasing demand and the sports apparel with improved comfort properties have become more popular than ever. Enhancing the wearer’s comfort is possible by engineering fabric structures by incorporating suitable fibers. For doing so, in this study, bilayered spacer fabric samples were produced from sustainable fibers namely, recycled PA66 and PA6-Umorfil yarns, together with 44 dtex elastane. A PA6 FDY monofilament yarn was employed as the spacer yarn. The results showed that comfort properties of sports apparel can be improved by using recycled and Umorfil poliamide fibers in different parts of the garments depending on the intended use and purposes. Use of such sustainable fibers in the fabric structure is not only suitable for achieving active sportswear comfort but also is respectful to the environment.

Aramid fabrics are used to produce most of the flame resistant protection clothes to fulfil the protection requirements. Even though aramid fibers have good thermal stability and flame resistance properties, fabrics used in protective clothing age and loss some of their essential functions under various environmental and operational conditions during their lifetime. These conditions cause serious limitations in the use of clothing. In this study, various woven fabrics produced from aramid (Nomex, Kevlar) fabrics were exposed to accelerated aging tests under varying temperature and time period in order to construct Neural Network models to predict weight loss and tensile strength loss percentages of the fabrics. The results of Artificial Neural Network models demonstrate that regression values are 0.98405 for weight loss percentages and 0.99935 for tensile strength loss percentages of the fabrics. Accordingly, the proposed Artificial Neural Network models are correctly constituted and the losses in determined fabric properties is successfully predicted.

Polyurethane materials can be used industrially in different ways, some of which can be used as textile materials or as auxiliary materials applied to textile materials. Polyurethane stands out as a widely used polymer for coating textile products used in outdoor applications, because of high stability at low temperature, flexibility, no or very little volatile organic component content, high water resistance, pH stability, excellent solvent resistance, weather resistance, and many other chemical and mechanical properties. In the study, cotton, polyester, and viscose fabrics were coated with polyurethane and aged under UV light to investigate the causes and behaviors of the mechanical degradation effects of UV on the coating material and fiber. The results indicate that the PU coating process improves the mechanical properties of textile materials while being exposed to UV rays deteriorates the fabric structure. The deterioration in the structure of raw and coated fabrics with the effect of UV increased the air permeability. According to the results of DSC analysis, the increase in the time of UV exposure did not create significant differences in terms of thermal degradation temperatures in both cotton and viscose fabrics. The glass transition temperatures (Tg) increase with more exposure to UV rays, and the UV exposure time had a negative effect on the melting temperature (Tm) and enthalpy (ΔH) of coated polyester fabrics.

This paper aims to investigate the influence of sewing thread properties, sewing process and repeated washing cycles on the strength reduction of sewing threads and seam strength of sewn samples. For this purpose, twenty-four commercial sewing threads with different types and linear densities were selected for the present study. The samples were sewn with specific sewing parameters. Half of the fabric samples were then subjected to 10 washing cycles. After sample preparation, the change in tensile properties after sewing and washing was calculated and the seam strength of the sewn and washed-sewn samples was measured. It was observed that the breaking strength of each parent thread was significantly higher than its corresponding sewn and washed-sewn thread strength. Considering the strength loss after sewing and after washing, it was found that, among the different types of sewing threads, the samples sewn with core-spun threads showed lower strength loss, while the samples sewn with cotton threads showed the highest loss. Moreover, the values of seam strength after washing are higher for PES-Co core-spun thread and mercerized cotton thread than before washing. However, an opposite trend was observed for the samples sewn with polyester spun and PES-PES core-spun thread. High correlations were observed between the parent thread and the strength of the sewn thread, the strength of the washed-sewn thread and the seam strength before washing.

Garment cut wastes from apparel industries are used for various applications in various industries. Normally garment cut wastes and recycled fibres from garment cut wastes are used in textile, furniture, carpet, paper, automobile, construction, and agricultural industries in low mechanical performance applications. In this research, composites are developed by using recycled fibres obtained from garment cut wastes as reinforcement and with different types of matrices. Recycled fibres used as reinforcements are obtained from garment cut wastes of cotton, polyester and cotton/polyester fabrics to develop these composites. These composites are developed by using Epoxy resin, Kaolinite, Polypropylene sheet as matrices. Reinforcements and matrices have used in different compositions and combinations to develop these composites. The main advantages of this type of composites are to combine the different properties of different materials to obtain unique and high-performance material. Technical properties like thickness, mass per unit area, Tensile strength, Flexural strength, Impact strength, Water absorbency and Scanning Electron Microscope of developed composites were tested and analyzed. The outcome of the results demonstrates that many of the composite proportions with different blend, reinforcement and matrcies show superior mechanical performances when compare it with each other, and it can be recommended for many potential applications.

The influence of the clothing type, and the laundry washing parameters have a huge impact on the number of microfibers/fibers being shed during the domestic laundry trails. Distressed and damaged clothing were identified as one of the important aspects of microfiber (MFs) pollution. Although some of the factors affecting the MFs shedding are still to be explored, thus there is a need for rigorous methods of identification and quantification to understand this shedding. A novel method was adopted using different combinations of wash loads and their corresponding temperature, wash duration, and agitation on the amount of MFs being shed. Results concluded that recycled polyester fleece and distressed jeans showed heightened shedding levels (approx. 49% of total emission). When real consumer laundry was compared to laboratory laundry, consumer domestic laundry is producing 110% more MFs than the laboratory tested fabrics. High temperature and increased wash time have a positive correlation (p-value

In this experimental study, it was aimed to research the possibilities of improving the dyeing properties of 100% polyester fabrics. For this purpose, the polyester fabrics were pretreated with sodium hydroxide and chitosan. The hydrophility of the pretreated fabrics were researched and they were then dyed with acid dye at 90 ⁰C. After dyeing processes, the CIEL*a*b* color values, color strength, fastness properties (to washing, water, perspiration, and rubbing) of dyed samples were investigated, and the bursting strength of the undyed and dyed samples was also tested. The results showed that it is possible to improve the dyeing properties of 100% polyester fabrics via chitosan application and that the polyester fabrics can be dyed with acid dyes at low temperatures after being cationized with chitosan following the NaOH application.

In this research, a new method developed with pixel coordinates is presented to obtain 3D body measurements from 2D images, to eliminate the need of the body to take measurements and to solve unfit problem in e-shopping. Front and side photographs are processed with new developed programmes named PixelList1.0 and Python 2.0. The sharp silhouettes, presented in authors’ another publication, are benefited with algorithms to reach pixel coordinates of feature points. Number of pixels in between feature points are saved, absolute values of differences consecutively are calculated, and 3D body measurements in pixels are obtained with different mathematical models. A conversion coefficient is introduced and size of a pixel is calculated accurately, 0.239 cm/pixel. 3D body measurements in centimeters are obtained by multiplying number of pixels by the size of one pixel in circle, ellipse, and hippodrome circumference equations. An overall accuracy rate of 93 % is concluded with the ellipse circumference equation.

Thin films produced by deposition of metal oxides on different surfaces show semi-conductor properties that are sensitive to the surrounding atmosphere components. With their optical, electrical, and structural properties, CdO metal oxides are used in a variety of fields ranging from optoelectronic materials to gas sensors. CdO thin films can be produced by different methods such as spray pyrolysis, SILAR, sol-gel spin coating and dip coating technique. The sol-gel dip coating technique, which is simple, accessible, adjustable, and repeatable based on desired parameters, is widely used in the production of CdO thin films. In this study, CdO metal oxide thin films were coated on polyamide, acrylic and cotton yarns by sol-gel dipping method in three different molarities of 0.1 M, 0.3 M and 0.5 M starting solutions. Structural properties of CdO thin film coated yarn samples were investigated using SEM and EDX analyzes were performed. The sensor tests of the yarn samples for LPG gas were carried out in the specially designed gas sensor measurement system and in the gas chamber. The 0.5 M CdO thin film coated cotton yarn samples showed better semiconductor properties and gas response than the other samples.

In this study yarn unevenness, diameter variation, hairiness and strength properties of slub yarns with various slub structures were investigated. The yarns (Ne20) in different slub thickness (1.2, 1.4, 1.6 and 1.8), slub length (1 – 3, 5 – 7 and 10 – 12 cm.), slub frequency (0.5, 3 and 6 pcs/m) and slub ramp length (1, 2 and 4 cm.) were produced from PET fibers. The multipopulation slub yarn which have two-slub length was also spun. The measurements of the yarns were made on the Fancy Yarn Profile of the Uster Tester 5 and the Uster Tensojet devices. The values of the test result were analyzed and evaluated statically. The slub parameters were found significant effect on the unevenness and strength properties of the yarns. As the slub thickness, slub length and frequency increased, the yarn unevenness, hairiness increased and the yarn strength decreased. Ramp length was found statistically significant for yarn breaking strength and elongation.
