There are significant problems in the production, use and waste management of petroleum-based polymers due to the increasing plastic waste problem, exceeding limit of the greenhouse gas emissions and decreasing fossil resources. The textile sector is the second sector that causes the plastic waste problem after the packaging sector. About 65% of the total yarn produced in the textile industry consists of yarns obtained from petroleum-based polymers. Biopolymers come to the fore in studies carried out within the scope of sustainability philosophies such as using of renewable raw materials, recycling at the end of their life and decomposition without harming the nature. In this study, it is aimed to produce biobased and biodegradable polybutylene succinate (PBS) polymer into multifilament yarn by melt spinning method and examine the effect of different winder speeds on the textile values of PBS yarns. In this context, multifilament yarns with round cross-sections were produced at 4 various winder speeds. The linear density, elongation (at Fmax) and tenacity of the produced yarns were obtained by performing analyzes, and also cross-sectional images of the filaments were also taken. The results suggested that the elongation (at Fmax) and dtex values decrease, and the tenacity value increases due to increasing winder speed. Additionally, the cross-section properties of the PBS multifilament yarn are smooth round sections and that the filaments in a yarn have similar diameters to each other.

In this study, cotton fabrics were treated with temperature-water responsive nanocomposites consisting of shape memory polyurethane (SMPU) and cellulose nanowhiskers (CNWs), for smart crease recovery/retention functions besides breathability with dynamic porosity. The smart crease recovery/retention functions were determined in air/water at different temperatures and relative humidity simulating laundry and drying processes and air permeability test was conducted at different fabric temperatures. Also, physical-mechanical properties (weight, thickness, bending rigidity, and strength) and washing fastness properties were evaluated. Fourier-transform infrared (FT-IR) and scanning electron microscope (SEM) analyses confirm the SMPU-CNW nanocomposite presence on fabric. Test results show that the treated cotton fabrics have not only dual responsive shape memory properties providing smart permeability, but also dynamic crease recovery/retention with enhanced mechanical properties. This method could contribute t ecological and economic aspects of sustainability as a result of less energy and polymer consumption with non-ironing property and treatment procedures and low chemical footprint.

The aim of this study is to investigate the influence of knitting structure and metal wire amount on the electromagnetic shielding effectiveness (EMSE) of knitted fabrics comparatively. Single jersey, single pique, weft locknit, and cross miss fabrics involving stainless steel or copper wires were produced on a flat knitting machine. A free space measurement technique was used for the EMSE measurements in an anechoic chamber. The variance analysis results of the EMSE values reveal that the effect of knitting structure, metal wire type, metal wire amount, and incident wave frequency is highly significant. It was observed that fabrics with tuck and miss loop structures had higher EMSE values than single jersey fabrics. It was found that single pique fabrics had higher EMSE values than single jersey fabrics that contain twice as much metal wire. It indicates that changing the knitting structure is more effective than changing the metal wire amount.

Phase change materials (PCMs) can store and release latent heat by making phase transitions between solid-solid or liquid-solid phases at specific temperature ranges. In the preparation of silk fibroin (SF) and chitosan (CHI) based phase change microcapsules and foam structures, the usage of virgin coconut oil (VCO) as a phase change agent was investigated, both forms were successfully prepared and characterized. Scanning Electron Microscope (SEM) and optical microscope with heating block analyzes were performed on microcapsules. SEM, Fourier-transform infrared spectroscopy, and differential scanning calorimeter analyzes were performed on foams. SF and CHI-based microcapsules had homogeneous size distribution and were thermally stable up to 60°C. Characteristic properties of the foam structures changed with the amounts of SF and CHI, and phase change occur at around 25°C, the melting temperature of VCO, resulting in energy absorption of 0.5287 W/g. Microcapsule and foam PCMs obtained can be used in different medical and thermoregulated textile applications.

Washed denim garments represent a popular field of fashion design, and environmental effects of denim washing are being increasingly explored since the process has adverse impacts on the environment due to its chemical discharge and other pollutant emissions that affect water sup-plies. As one of the biggest suppliers of denim apparel manufacturing worldwide, Turkey has also faced problems of high water consumption and pollution. To reveal the pressure on the envi-ronment caused by the denim washing sub- sector in particular, the water related environmental negative impacts in the industry need to not only be quantified, but also reduced. Accordingly, the study was conducted to develop a sustainable washing process for blue jeans for a medium scaled, commercial denim apparel washing plant. The results showed that the sustainable washing approach displayed superior performance with 36% lower grey water footprint (GWF), lower environmental impact in all categories, 28% lower overall energy demand, 50% lower natural gas and 36% lower direct water resource consumption with similar garment quality and washing effect attained.

Bacterial cellulose (BC) is a popular biomaterial which is used in innovative research in many fields thanks to its unique properties. In this study, BC as bio nonwoven structures are produced in Kombucha culture using ‘acetobacter xylinum’ bacteria in a static culture setting. Bio nonwoven surfaces are produced with the sandwich composite model. They use 15-25-60% cotton/ viscose/ polypropylene nonwoven surface fabric and 80-20% polypropylene /viscose nonwoven surface fabric while creating bio nonwoven surfaces. Water retention, porosity, dust retention, FTIR (Fourier Transform Infrared Spectrophotometer), SEM (Scanning Electron Microscope), and TGA (Thermogravimetric Analysis) analysis of the obtained BC structures are investigated. As a result of the analysis, it is determined that the BC and BC composite structures, which have undergone hydrogen peroxide and sodium hydroxide applications, have properties that can be used for medical purposes.

Efficient use of capacity is significant to enable apparel businesses to work cost-effectively and provide timely service to their customers. The increase in assembly-line efficiency is associated with lower operating costs. Therefore, the main purpose of balancing assembly lines is to manufacture products as profitable and as quickly as possible. In this study, we consider a single-model assembly line balancing problem with workforce and machine constraints in the sewing department of an apparel company. We develop an integer programming (IP) model to optimally balance the shirt production line, considering parallel machines in each stage of the line and various operational constraints such as cycle time and precedence constraints, task machine eligibility, the number of operators available. The IP model can either minimize the number of open workstations or both, minimize the number of open workstations and assign tasks in subassembly parts as close to each other as possible. The model has been run under various scenarios using LINGO 15.0 optimization software. Additionally, we have balanced the shirt production line using the Ranked Positional Weight Method (RPWM). The IP model outperforms the RPWM results across all scenarios and finds 33 stations and 86.8% efficiency compared to 38 stations and 75.4% balance efficiency with the RPWM.

The weak bonds between the layers of a part produced by the Fused Deposition Modeling (FDM) method causes damage at an early stage. To overcome the strength problem, FDM parts are manufactured with engineering thermoplastics or reinforced with carbon/glass fiber. Although these studies provided partial improvement on the mechanical strength of the part, the bond strength between the layers was not significantly improved. In this study, we aimed to reduce the negative effect of the weakness in the interlayer bond strength on the strength of the final part. Therefore, a composite laminate was applied on a polylactic acid (PLA) core produced by the FDM method. Weight measurement, tensile test, three-point bending test and weight drop test were performed on the produced test samples. Tensile and bending test results indicates that the composite layer applied on the core produced by the FDM method has a positive effect on the mechanical strength and bending properties. It is concluded that the study will be a source for future research on moldless composite production.

It is common to use open-end rotor yarn in the production of denim fabric, which is preferred by people of all ages and social status due to its durability and comfort. Recently, the demand for stretch denim fabrics that can take the body's shape due to the elastic fibers in its structure has been increasing. However, producing elastane-containing yarns in the rotor spinning system is not as practical as ring spinning. For this reason, this study aimed to use the staple Sustans® fibers with high elasticity in the rotor spinning system together with cotton fibers and reflect the good elasticity and elongation properties of Sustans® fibers to the rotor yarns and denim fabrics. In the study, the staple Sustans® fibers based on PTT (Polytrimethylene Terephthalate) were spun with cotton fibers in the rotor spinning system. Then denim fabrics were produced using these yarns in the weft. Later, strength (breaking and tear), dimensional stability (dimensional change after washing, fabric elasticity and growth), abrasion resistance and pilling tests were applied to the produced denim fabrics. Thus, the effects of using Sustans® fibers on the strength, dimensional stability, abrasion and pilling properties of denim fabrics were analyzed. As a result of the study, the dimensional change and growth values after washing were developed by using Sustans®. Although good dimensional stability was observed in the samples, the degree of elasticity was lower than expected. The use of Sustans® at rates of 50% and above improved the pilling values of the fabrics. In addition, it has been determined that the use of Sustans® in terms of abrasion resistance has a more positive effect at the end of long wear periods.

This study aimed to develop a vibro-haptics feedback based smart corset to stimulate humans to be in ideal posture by monitoring the spline in thoracic vertebrae of T5-T12 levels, and provide a vibro-tactile stimuli to human's skin at lumbar L3 level. A corset contains a microcomputer, sensors and an actuator was implemented on 12 participants for 2 cases to determine its efficiency. In the first case, tactile stimuli was not provided to the participants, while in the second case tactile stimuli was ensured. The results showed once the vibro-tactile stimuli was represented to the participants, their posture regime improved significantly with a value of 53.13±23.14 %. Moreover, it was also observed that their non-ideal postural duration significantly decreased. These results suggest that the corset provides vibro-tactile feedback that encourage humans in seated posture to beneficial postural habits while using computers.
