Publication A research on effect of surface treatment conditions on flammability and water repellency properties of drapery fabrics produced from micro polyester yarns(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-9756-2021Flame 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.Publication Peel resistance and stiffness of woven fabric with fusible interlinings(Inst Natl Cercetare-dezvoltare Textile Pielarie-bucuresti, 2019-01-01) Gurarda, Ayca; GÜRARDA, AYÇA; Kanık, Mehmet; KANIK, MEHMET; Çalışkan, Naime; Bursa Uludağ Üniversitesi/Mühendislik Fakültesi.; JTS-3559-2023Interlining is a layer of fabric placed between the garment fabrics to form and enhance the stiffness of the garment. The fusible interlining can be bonded to the fabric at a specific temperature, time and pressure. These parameters are very important for the peel resistance and stiffness of the fabric with fusible interlining.In this study, cotton woven face fabric and three different fusible interlinings(plain, twill and nonwoven fusible interlining) were chosen as experimental samples. Different fusing temperatures between 130 degrees C and 170 degrees C and different fusing times (5-10 and 15 sec) selected for fusing of the interlinings to the fabric. The purpose of this study is to investigate the effect of fusing temperature and time on peel resistance and stiffness of fabric with fusible interlinings. Results indicated that the stiffness of the fabric withcotton plain fusible interlining increased with increase fusing temperature and fusing time. Results indicated that the stiffness of the fabric withpolyester twill fusible interlining increased with increase fusing temperature and decrease fusing time. Results indicated that the stiffness of the fabric with polyamide nonwoven fusible interlining increased with increase fusing temperature until 140 degrees C and increase fusing time until 10 sec. Results indicated that the peel resistance between the cotton plain and polyester twill fusible interlining andface fabric increased with increase fusing temperature and fusing time.
