The issue of clothing is one of the problems that come with ageing. Despite the need, there is no athlete for women aged 65 and over in the market. In this study, first, a survey was conducted on the issuesfaced by women over the age of 65 while using athlete. The functional and comfortable special athlete for summer and winter was designed to solve and eliminate the problems by analysing the obtained results. In the study, first, 100% cotton, 100% bamboo, 100% viscose, cotton/bamboo and cotton/viscose blended fabrics were produced in a single jersey knitting structurefor summer athlete. 100% cotton fabric was produced in the interlock knitting structure for winter athlete. Second, these fabrics were pre-treated, and the finishing treatments to provide some functional properties such as softness (cationic, microemulsion and macroemulsion silicones) and antibacterial properties were applied to these fabrics. After the finishing treatments, tests and analyses were carried out, and the fabric weight, elasticity and bursting strength tests were carried out to determine the physical properties of the fabrics. To determine the comfort properties of the fabrics, air permeability, water vapour permeability and thermal comfort properties tests were performed. According to the results, the functional and comfortable summer and winter athlete were determined and produced for older women. At the end of the study, a clothing trial was also made with the produced woman athletes.

This study investigated the thermal comfort properties of knitted fabrics produced from newly engineered Umorfil® yarns and their blends with Tencel®, wool, acrylic and polyester yarns. Single jersey-knitted fabrics were produced with 50/50% blended yarns (Umorfil®/Tencel®, Umorfil®/wool, Umorfil®/acrylic, and Umorfil®/polyester) and with 100% Umorfil® yarn for comparison. In this regard, the thermal comfort properties (thermal conductivity, thermal resistance, thermal absorptivity), air permeability, relative water vapour permeability, water absorbency, and wicking characteristics of these fabrics were measured and evaluated statistically. The results revealed that, 100% Umorfil® and 50/50% Umorfil®/Tencel® fabrics provided better characteristics in terms of thermal conductivity, air permeability, water absorbency, wicking behaviours, and colder feelings for the use of fabrics in hot climate products. It is also suggested that owing to the synergistic effect of these two materials, the blend of Umorfil® with Tencel® enhanced the thermal comfort and liquid moisture transmission capacities of the fabrics.

In recent years, the importance and use of wet-white tanning technology have increased due to the increase in environmental and health concerns. On the other hand, this technology still has problems related with fixation of dyestuff and fatliquoring agents during wet-end processes. In this study, the effect of the use of different commercial amphoteric retanning agents in different ratios on dyestuff consumption was investigated. For this purpose, amphoteric polymers were used at the beginning of dyeing process of syntan tanned leathers and the concentrations of remaining dyestuff after the process have been measured using UV-Vis Spectrophotometer for each trial. From the results it was concluded that the use of amphoteric polymers in retanning of wet-white tanned leathers significantly decreased the remaining dyestuff in the floats. Also, the physical and mechanical properties of the final leather were not adversely affected up to the use of 6 wt% the amphoteric polymer.

In this study, biodegradable polycaprolactone (PCL) nanofibers were copper (Cu) electroplated in a more environmentally friendly bath compared to conventional electroplating baths. The Cu-plating mechanism and determination of the optimum parameters for the production of Cu-plated PCL nanofiber mats were explained. PCL nanofibers were produced on metal frames by electrospinning. Cu-electroplating needs a conductive surface. To provide this, a gold/palladium mixing was sputtered on the PCL samples with different sputtering thicknesses. After determining the minimum sputtering thickness, the samples were Cu-plated for 1,3,5 and 30 minutes in the electroplating bath. Surface properties of the samples were evaluated after nanofiber production, Au/Pd sputtering and electroplating, respectively. Elemental analyses, mapping and electrical characterizations were also performed after electroplating. The Cu-coated areas gave a sheet resistance in the range of milliohms indicating a highly conductive structure. Every step of the study is described in detail to provide insight for further studies.

In this work, the Ultra High Molecular Weight Polyethylene [UHMWPE] fabric sample was coated using hand-lay technique with polyester resin and two types of fillers to improve the impact resistance property. The matrix comprises polyester resin with fillers like, Coconut shell powder and Boron carbide separately, in four different weight ratios [0%, 10%, 20% and 30%]. The influence of Coconut shell powder as well as Boron carbide on impact energy absorbing characteristics of the composites was studied. The impact resistance was found to be higher with the use of fillers. The Coconut shell powder provided better impact resistance about 45% higher than the Boron carbide. The average total energy absorbed by the Coconut shell powder sample ranged from 68 J to 69 J whereas the control sample absorb 47 J. Similarly the Boron carbide too provided better impact resistance by 19-36% compared with the control sample. The average total energy absorbed by the sample ranged from 56 J to 64 J. Results reveal that the increase in the percentage of Coconut shell powder filler did not significantly increase the impact resistance of UHMWPE whereas an increase in the percentage of Boron carbide improved the impact resistance, however higher percentages were found to reduce the impact resistance.

Green polymers have gained popularity in recent decades because of the rising pollution in the world. Poly(butylene succinate) (PBS) is an aliphatic polyester and a relatively new polymer. PBS is regarded as one of the most promising materials for various applications due to its exceptional processability and regulated biodegradability and attracts the attention of many researchers. The application fields of its products when combined with the solution blow spinning (SBS) method, may be expanded to textiles, food, packaging, filters, batteries, and biomedical due to its outstanding biodegradability, processability, and thermal and chemical resistance. Therefore, this study focused on the SBS process as a PBS polymer solution to scale up the nanofibers manufacturing process to the commercial level. In this research, PBS nonwovens were produced by an SBS apparatus. The effects of spinning parameters (solution concentration, air pressure, and flow rate) on the average fiber diameter were studied. The PBS solution blown nonwovens was characterized by scanning electron microscopy. A software was used to measure fiber diameter and distribution. PBS nonwovens were mostly on a nanometer scale with the presence of a few defects. A full factorial design was used to the test data for statistical analysis to investigate how solution concentration, air pressure, and flow rate influenced average fiber diameter. The impact of process control factors is examined using analysis of variance. Results have shown that solution concentration significantly influenced of mean diameter. The fast and economic feature of the SBS process, as well as the environmentally friendly nature of the PBS polymer, may considerably contribute to the industrial-scale manufacturing of nanofibrous nonwoven made from this polymer.

An investigation of Poisson’s ratio of a series of spun bonded non-woven fabrics, differing in areal density, number of layers, testing directions and finishes, is reported. The Poisson’s ratio value is found to be higher with increase in the number of layers of spun bonded fabric assembly of fabrics of same Grams per Square Metre (GSM). The contraction in cross direction is higher than in the machine direction. Since spun bonded non-woven fabrics are anisotropic in nature, the Poisson’s ratio values range from 0 to 0.728 for the various extension levels that have been considered depending on the direction of action of the tensile force in the machine (MD) and cross directions (CD). The relationship between Young’s modulus & bending rigidity is poor. Flexural rigidity and Young’s modulus in machine direction are higher than in cross direction.

A bioretanning agent was developed as an alternative to conventional synthetic retanning agents to pave the way for sustainability in the leather industry. Tanned solid waste shavings obtained from leather processing was utilized to produce a proteinic sub-structure for constitution building block of the bioretanning agent's backbone. The protein hydrolyzates were acquired with different molecular weights and the hybrid biopolymers were obtained by grafting the hydrolyzates with acrylic acids (AAc) and acrylamides (AAm). To evaluate the properties imparted by the designed bioretanning agent, it was incorporated into the leather in the retanning processes and compared to the control samples fabricated with conventional procedures. Penetration of hybrid biopolymer into the matrix for retanning was achieved easily, and using low and high molecular weight biopolymers have been recorded by 20% and 23% of improvement on the mechanical performance of the leather samples, respectively. The ratio of the hydrolyzate and AAm/AAc was found to be fitted at 1:2 for both. Furthermore, as per the evaluation of the leathers retanned by novel biopolymer, the results were promising in terms of technical viability and revealed that the biopolymer usage could enhance the mechanical performance of the leather while benefiting from the waste-to-wealth approach.

In parallel to the development of new fiber and yarn technologies, different fibers and yarns have been used in denim fabric production and breaking the market dominance of 100% cotton yarn in the denim market. In recent years, the use of elastane fibers for denim fabric production has rapidly increased thanks to their movement comfort. This study examines the strength and elasticity properties of denim fabrics containing core yarns. For this purpose, different weft yarns were used in the production of denim fabrics. While 100% cotton ring yarn was used as warp for all fabrics, cotton ring, cotton OE-rotor, cotton / PBT-elastane dual-core, cotton / elastane core and cotton-PET / elastane core yarns were used as weft. Within the scope of the study, tensile strength, tearing strength and bursting strength tests were carried out on denim fabrics. In addition, denim fabrics contain core spun yarns were tested for elasticity in the weft direction, which is the direction of core yarns used. When the results were examined, it was seen that tensile strength and breaking elongation are higher for the fabrics containing core yarn in general. Fabrics produced with dual-core yarns have the highest tearing strength values. In addition, the bursting strength values of fabrics containing core yarn are higher than fabrics without core yarn. It was seen that the elasticity values of denim fabrics produced using core yarn are generally above 50%. However, the highest growth values were seen in the fabrics with the highest elasticity.
在新纤维和纱线技术不断发展的同时，不同的纤维和纱线被用于牛仔布生产，打破了100%棉纱在牛仔布市场的主导地位。近年来，由于弹性纤维的运动舒适性，其在牛仔布生产中的应用迅速增加。本文研究了含芯纱牛仔布织物的强度和弹性性能。为此，在牛仔织物的生产中使用了不同的纬纱。所有织物的经纱均采用100%纯棉环纱，纬纱采用纯棉环纱、纯棉oe -转子纱、纯棉/ pbt -弹性双芯纱、纯棉/弹性芯纱和纯棉- pet /弹性芯纱。在研究范围内，对牛仔布进行了拉伸强度、撕裂强度和破裂强度试验。另外，对含包芯纱的牛仔布织物在包芯纱使用方向的纬向进行弹性测试。结果表明，含芯纱织物的抗拉强度和断裂伸长率一般较高。用双芯纱生产的织物具有最高的撕裂强度值。此外，含包芯纱织物的破裂强度值高于不含包芯纱织物。结果表明，采用包芯纱生产的牛仔面料弹性值一般在50%以上。然而，在弹性最高的织物中，生长值最高。

However, the highest growth values were seen in the fabrics with the highest elasticity.","PeriodicalId":22221,"journal":{"name":"Tekstil Ve Konfeksiyon","volume":" ","pages":""},"PeriodicalIF":0.6,"publicationDate":"2023-01-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48297393","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study investigates the effects of fabric properties and ultrasonic welding on the performance of surgical gowns. For this purpose, eight spunlace fabrics with different structural properties were provided. First, the fabrics’ thickness, tensile strength, elongation at break, air permeability, drape behavior, and surface friction properties were investigated. Then the fabrics were sewn with the ultrasonic sewing machine. Afterward, the sewn fabrics’ seam strength, air permeability and drape behavior were tested. The results were statistically evaluated. Based on the data obtained, a detailed comparison was made between the fabrics with respect to the expectations of the surgical gowns. The higher the polyester content in the fabric, the higher the fabric strength, seam strength and air permeability. However, viscose-rich fabrics have a softer hand and are easier to drape compared to polyester fabrics. Moreover, sewing process leads to a decrease in the drape and air permeability of the fabrics.
