(Taylor & Francis, 2020-03-05) Gunaydin, Gizem Karakan; Ceven, Erhan Kenan; ÇEVEN, ERHAN KENAN; Gurarda, Ayca; GÜRARDA, AYÇA; Akgun, Mine; AKGÜN, MİNE; Bursa Uludağ Üniversitesi/Mühendislik Fakültesi/Tekstil Mühendisliği Bölümü.; 0000-0003-3283-4117; AAG-4653-2019; AAG-9756-2021
Flame retardancy and water repellency are frequently applied finishing processes for drapery fabrics. These two treatments should require special attention when they are applied consecutively. This research aims to investigate the effect of sequential finishing processes by utilizing of different flame retardant chemical ratio (0, 60 and 90 g/l) and fluorocarbon based water repelling substance ratio (0, 10 and 30 g/l) on hydrophobic, flammability, air permeability and stiffness properties of the drapery fabrics. According to the results of statistical analyses, it was determined that fabric burning behaviour, air permeability and stiffness properties were significantly influenced from the process types with different finishing substance ratios and from the weft yarn density as well as from the interaction of process type and weft yarn density at 0.05 significance level. Additionally, process type was a significant factor on water repellency of drapery samples however weft yarn density and the interaction of weft yarn density and the process type were not influential factors on water repellency at significance level of 0.05. For both warp and weft fabric directions, lowest damage zone at the length and width with the ignition source was obtained from the samples which were only treated with flame retardancy process without water repellency (90-0 coded process). The most satisfying results in terms of water repellency were obtained from the samples treated with 60-30 coded process where 60 g/l FR and 30 g/l water repellent chemical substances were utilized respectively. Drapery fabrics treated with 60-0 coded process revealed the best windproof feature indicating the lowest air permeability.

(Inst Natl Cercetare-dezvoltare Textile Pielarie-bucuresti, 2016-01-01) Çeven, Erhan Kenan; Aytaş, Hüseyin; ÇEVEN, ERHAN KENAN; Aytaş, Hüseyin; Uludağ Üniversitesi/Mühendislik Fakültesi; 0000-0003-3283-4117; AAG-4653-2019; EMH-5235-2022
This paper is focused on the selected parameters that influence the abrasion and friction properties of composite yarns containing metal wire. In the experimental study, the composite yarns containing metal wire were produced on a hollow spindle twisting machine according to the method of covering. The composite yarns containing metal wire were produced with seven different cover yarns varying in their raw materials and structures. These were: polypropylene, cotton, polyester/cotton core-spun, continuous filament polyester, continuous filament nylon 6.6, polyester/polyester core-spun, and polyester cut fiber yarns. These yarns were cross covered over stainless steel (SS) wires having two different diameters of 50 pm and 100 pm. The performance tests selected for these yarns were abrasion and friction as because these types of yarns are vulnerable to rubbing. Abrasion tests of composite yarns containing metal wire were performed with a modified crockmeter test instrument while the friction tests were carried out by using a yarn friction coefficient measurement device. According to the results of the statistical analyses performed using the experimental values obtained from the tests, abrasion resistance and friction properties of the composite yarns were affected by the yarn parameters like cover yarn type and wire diameter.

Knitted fabrics with a wide range of fabric construction varying in fibre type, yarn type is frequently preferred by consumers owing to their high comfort properties. Today new, functional and biodegradable, natural fibre based raw materials are mostly considered for knitted fabrics and clothing designs with a sustainable consumer manner. Collagen peptide added fibres are the recent improved regenerated cellulosic fibres which are known to be providing a skin friendly texture with high thermal and moisture comfort. Within this study, some performance properties such as thermal properties, water vapour permeability, water vapour resistance, air permeability as well as bursting strength of greige and dyed knitted samples made of 100 % Tencel (TM), Modal, Cupro, Umorfil (R), combed cotton and carded cotton yarn were evaluated. ANOVA test was performed for the statistical evaluation of yarn and fabric properties. According to ANOVA results, regenerated cellulosic yarn type of knitted fabrics and the process type (untreated greige fabric or dyed fabric) were generally significant factors on mentioned performance properties of knitted fabrics. The results of experiments also revealed that beside the regenerated cellulosic fibres, new developed collagen peptide added Umorfil (R) fibre may be used as the raw material of knitted fabrics for sport garments with satisfying comfort results.

Different yarn spinning methods with different fiber combinations provide an optimization for the consumer requests of durability, functionality, comfort, and price. Vortex yarns and the fabrics produced from these yarns have aroused interest for the last years owing to lower yarn production cost and the satisfying fabric comfort properties. Within this work, core-spun vortex knitted fabrics of three different yarn count (400, 300, and 200 dtex) with six different core yarn type (70 dtex Polyvinyl alcohol, 110/36 dtex/filament polyester yarn, 80/36 dtex/filament polyester yarn, 110/333 dtex/filament micro polyester yarn, 50/96 dtex/filament, 120 dtex staple polyester vortex yarn) and two different sheath sliver types (100% viscose, polyester-viscose blended sliver) were studied. Moisture management transport property (MMT), water vapor permeability, and air permeability properties of those knitted fabrics were evaluated comparatively. Obtained results were statistically evaluated using three-way ANOVA test. It was determined that core yarn type, sheath sliver type, and yarn linear density were generally influential factors on MMT, water vapor permeability, air permeability properties of the core-spun vortex fabrics at significance level of 0.05. Correlation analyses between yarn hairiness and water vapor permeability as well as between yarn hairiness and air permeability were indicated. The conducted work provides an initial phase toward a better understanding of influence of some core-spun vortex yarn parameters on comfort properties of knitted fabrics.

In recent years, garments made of fabrics with elastane are highly preferred. A garment made of fabric with elastane is able to stretch by about 10-30% and recovery immediately after release. In the apparel industry, sewing should not prevent the fabric from stretching in the garments made from woven fabrics with elastane. The elasticity of the seams of the garments consisting of elastic fabrics is very important. In this study, it is aimed to examine the stretch and permanent elongation properties of different stitch types of garments made of elastane woven fabrics. For this purpose, 5 different stitch types were selected as lockstitch, zig zag stitch, two thread chain stitch, three thread overlock stitch and five thread overlock stitch, and these stitches were sewn at different stitch densities (3 - 4 and 5 stitches / cm), with different sewing threads (spun polyester, core spun (poly / poly), nylon and elastic sewing thread) with different ticket numbers (80 and 120). The stretch and permanent elongation values of the sewn fabric samples were examined.

According to test results, cotton/Tencel Buldan fabrics indicated similar comfort properties with the 100% cotton Buldan fabric properties. Additionally the lowest thermal absorptivity was observed from 100% cotton Buldan fabrics which give the warmth feeling among the evaluated samples.
Literature survey on abrasion problem in chenille yarns
(Pamukkale Univ, 2006-01-01) Çeven, Erhan Kenan; ÇEVEN, ERHAN KENAN; Özdemir, Özcan; ÖZDEMİR, ÖZCAN; Bursa Uludağ Üniversitesi/Mühendislik Fakültesi/Tekstil Mühendisliği Bölümü.; 0000-0003-3283-4117; AAG-4653-2019
Chenille yarns are traditionally used in the manufacture of furnishing fabrics, fashion knitwear, and as decorative threads in many types of broad and narrow fabrics. Chenille yarn has a very distinct weakness-it does not have very good inherent abrasion resistance. When the yarns are in use, clearly the abrasion resistance of the chenille yarn is crucially important. Either during further processing or during the eventual end-use, any removal of the effect yarn forming the beard will expose the ground yarns, which in turn will result in a bare appearance. To avoid this undesirable result, several options are available. Therefore, the studies on this area are about the investigation of the influences of some material types and machine parameters on the abrasion resistance of chenille yarns and fabrics produced with these yarns. In this paper, the experimental studies about the abrasion properties of chenille yarns in yarn, knitted and woven fabric forms are summarized.
