Determination of para-aramid single Fabric shear by yarn pull-out and analysis by statistical model
Fibers and Polymers, 2013Co-Authors: Kadir BilisikAbstract:The aim of this study was to determine the para-aramid Fabric shear by the pull-out method. The Fabric sample dimensions and the number of pull-out ends were identified as important parameters. Fabric shear depended on Fabric Density. Fabric shear strength increased when the number of pulled ends increased. When the Fabric length increased, Fabric shear strength generally increased. The number of pulled ends and the Fabric sample dimensions influenced the Fabric shear rigidity. Shear jamming angles were found based on the number of pulled ends. The results showed that para-aramid Fabric shear could be measured by yarn pull-out test.

analyses and statistical modeling of crimp extension stage of single and multiple yarn ends pull out in textured polyester woven Fabric
Journal of Industrial Textiles, 2013Co-Authors: Kadir Bilisik, Oguz Demiryurek, Gaye YolacanAbstract:The aim of this study was to understand the crimp extension stage of yarn, being pulled out of Fabric. Polyester woven Fabrics were used to conduct the pull-out tests. Yarn pull-out crimp extension depends on sample dimensions, Fabric Density, Fabric weave, crimp ratio and the number of pulled ends in the Fabric. Results showed that multiple and single yarn pull-out crimp extensions of long samples were higher than those of short samples, and the multiple yarn pull-out crimp extension was higher than that of the single-yarn pull-out force, and the crimp extensions in Fabrics were proportional to their crimp ratios. Satin Fabric weave showed high weft directional single and multiple pull-out crimp extension compared to plain and ribs Fabric weaves. The developed regression model may be helpful for the design of multifunctional Fabrics in technical textile applications.

experimental determination of yarn pull out properties of para aramid kevlar woven Fabric
Journal of Industrial Textiles, 2012Co-Authors: Kadir BilisikAbstract:The aim of this study was to determine the pull-out properties of the para-aramid woven Fabrics. Para-aramid Kevlar 29® (K29) and Kevlar 129® (K129) woven Fabrics were used to conduct the pull-out tests. K29 and K129 woven Fabrics had high and low Fabric densities, respectively. For this reason, yarn pull-out fixture was developed to test various K29 and K129 Fabric sample dimensions. Data generated from single and multiple yarn pull-out tests in various dimensions of K29 and K129 woven Fabrics included Fabric pull-out forces, yarn crimp extensions in the Fabrics, and Fabric displacements. Yarn pull-out forces depended on Fabric Density, Fabric sample dimensions, and the number of pulled ends in the Fabric. Multiple yarn pull-out force was higher than single yarn pull-out force. Single- and multiple-yarn pull-out forces in K29 (tight Fabric) were higher than those of K129 (loose Fabric). Yarn crimp extension in K29 and K129 Fabrics depended on crimp ratio in the Fabrics and Fabric Density. High crimp rati...

Gamma radiation shielding effectiveness of cellular woven Fabrics
'SAGE Publications', 2018Co-Authors: Özdemir Hakan, CamgÖz BerkayAbstract:WOS: 000418377600009Lead-shielding products, such as lead aprons, are important materials for personal protection of physicians and patients from X-ray (gamma) radiation during medical operations. However, lead has environmental disadvantages such as high toxicity. The aim of this study was to manufacture an environmentally friendly and flexible textile-based radiation shielding material. In this work, 3/1 twill and some cellular woven Fabrics were produced with conductive core yarns, and gamma radiation shielding effectiveness of these cellular woven Fabrics were investigated and compared with that of the 3/1 twill woven Fabric, which are commonly used as uniforms and were not studied previously in any other literature. The effects of weave on the structural characteristics of Fabric such as the conductive weft yarn Density, Fabric thickness, and fullness were analyzed graphically and statistically. It is observed that with indenting and protruding, structure cellular woven Fabrics performed better gamma radiation shielding performance than the 3/1 twill woven Fabrics. The sample B1, woven with cellular weave 1, has the highest gamma radiation shielding effectiveness, thanks to the highest Fabric thickness. In addition, the increase in the conductive core yarn Density improved the gamma radiation shielding effectiveness of the woven Fabrics

Inst Natl Cercetare-Dezvoltare Textile Pielarie-Bucuresti, 2018Co-Authors: Özdemir Hakan, CamgÖz BerkayAbstract:WOS: 000428652100007Lead aprons that are lead-shielding products are generally used for personal protection of physicians and patients from X-ray (gamma) radiation during medical operations; lead has environmental disadvantages, with high toxicity, though. Therefore, the aim of this research was to produce an environmentally friendly and flexible textile-based radiation shielding material. In this work, 2/2 twill, 3/1 twill, Herringbone, Whipcord, which are twill derivatives, Barathea and Crepe woven Fabrics, which are sateen derivatives, woven with textured steel yarns, which have soft feeling and flexibility, and gamma radiation shielding effectiveness of these Fabrics were investigated and were not studied in the references. The effects of Fabric structural characteristics such as weave, conductive weft yarn Density, Fabric thickness and porosity on these properties were analysed graphically and statistically. It is observed that with the biggest thicknesses and lowest porosities, Barathea and Crepe woven Fabrics performed better gamma radiation shielding performance than other woven Fabrics. The samples F1 and E1, woven with Barathea and Crepe weave, have the highest gamma radiation shielding effectiveness, thanks to the highest Fabric thicknesses and lowest porosities. In addition, the increases of textured steel yarn Density improved the gamma radiation shielding effectiveness of woven Fabrics

Statistical Modeling of Thermal Properties of Biobased Compostable Gloves Developed from Sustainable Polymer
Fibers and Polymers, 2018Co-Authors: Muhammad Maqsood, Gunnar SeideAbstract:Polylactic acid (PLA) is a biodegradable and compostable polymer obtained from annually renewable resources and is acknowledged to be sustainable and non-polluting polymer with substantial commercial prospective as a textile fiber however, there is lack of literature on apparel applications of this polymer. Therefore in this study it was aimed to develop biobased compostable gloves from PLA draw textured melt spun yarns and to examine the effect of yarn linear Density, Fabric structure and stitch Density on thermo-physiological comfort and moisture management properties of PLA based gloves. 100 % PLA based multifilament yarns of two different linear densities were melt spun and later draw textured on false twist texturing machine to be used for gloves knitting. Single jersey and rib structures were produced with two different stitch densities to investigate their effect on thermal conductivity, thermal resistance, relative water vapour permeability, air permeability and moisture management properties of the gloves. Minitab statistical software was employed to analyze the results of test samples. The coefficients of determinations (R^2 values) presented good estimation capability of the established regression models. The outcomes of this research may be useful in determining suitable manufacturing requirements of PLA based gloves to accomplish precise thermo-physiological and moisture management properties.

modeling the effect of elastane linear Density Fabric thread Density and weave float on the stretch recovery and compression properties of bi stretch woven Fabrics for compression garments
Journal of The Textile Institute, 2016Co-Authors: Muhammad MaqsoodAbstract:The aim of this study was to investigate the effect of elastane linear Density, thread Density, and weave float on the stretch, recovery, and compression properties of bi-stretch woven Fabrics for compression garments. Fabric samples were produced using elastane core-spun cotton yarns both in the warp and weft. The elastane linear Density, Fabric thread Density, and weave float size were used as input variables while Fabric contraction, subgarment pressure, Fabric stretch, and recovery were taken as response variables. Two different elastane linear densities, i.e. 44 and 78 dtex, two different thread densities, and three different weave designs, i.e. 1/1 plain, 2/2 z-twill, and 3/3 z-twill were used. The results of Fabric samples were analyzed in Minitab statistical software. The coefficients of determinations (R-sq values) of the regression equations showed good prediction ability of the developed statistical models. The findings of the study may be helpful in deciding appropriate manufacturing specifica...
