TY - JOUR T1 - Comparison of the Selected Physical Properties of Elastane Weft Knitted Fabrics Before and After Repeated Launderings TT - ELASTAN İÇERİKLİ ATKILI ÖRME KUMAŞLARIN BAZI FİZİKSEL ÖZELLİKLERİNİN YIKAMA ÖNCESİ VE TEKRARLI YIKAMALAR SONRASINDA KARŞILAŞTIRILMASI AU - Karakan Günaydın, Gizem AU - Kenan Çeven, Erhan AU - Eren, Hüseyin Aksel PY - 2019 DA - April Y2 - 2019 DO - 10.17482/uumfd.481041 JF - Uludağ Üniversitesi Mühendislik Fakültesi Dergisi JO - UUJFE PB - Bursa Uludağ University WT - DergiPark SN - 2148-4155 SP - 35 EP - 50 VL - 24 IS - 1 LA - en AB - It was aimed to investigate the influence ofwashing cycle and fabric type on stretching (%), unrecovered elongation (%) andelastic recovery properties of plain knitted fabrics made of different groundyarn types having the same elastane ratio (%). For the plain knitted fabrics;Elastane ratio was kept constant as 5% for all fabric types whereas the groundyarns were selected as 70% polyester 30% cotton vortex yarn, 70% polyester30%viscon ring yarn, 70% polyester 30%cotton ring yarn, 100%viscon vortex and100% cotton ring spun yarns respectively. Knitted samples were objected torepeated laundering and flat dried after each washing cycle. Fabricweight (g/m2) after the washing cycles of 1, 5 and 10 werepremeasured. Fryma fabric extensometer device was used fordetermining the stretching ratios (%), unrecovered elongation (%) and elasticrecovery (%) of the samples both in wale and course way. Two-Way ANOVA wasperformed in order to investigate the influence of washing cycle and fabrictype on stretching (%) and unrecovered elongation (%) properties of theelastane knitted fabrics. KW - plain knitted fabrics KW - elastane KW - washing cycle KW - stretching ratios (%) KW - unrecovered elongation (%) KW - elastic recovery (%) N2 - Bu çalışmadaaynı elastan oranına sahip ancak farklı zemin ipliklerden üretilen düz örmekumaşların esneme (%), geri toparlanamama (%) ve elastik toparlanma özelliklerineyıkama tekrar sayısı ve kumaş tipinin etkisi incelenmeye çalışılmıştır. Düzörme kumaşlar için elastan oranları tüm kumaşlar için sabit tutulurken (%5)zemin iplikleri sırasıyla; %70 poliester %30 pamuk vorteks iplik, %70 poliester%30 viskon ring iplik, %70 poliester %30 pamuk ring iplik, %100 viskon vorteksiplik, %100 pamuk ring iplik olarak seçilmiştir. Numuneler tekrarlı yıkamaişlemine tabi tutulmuş olup her yıkama devri sonrasında sererek kurutmayapılmıştır. 1,5 ve 10 devir yıkama sonrası kumaş gramajları belirlenmiştir. Numunelerin çubuk ve sıra yönlü esneme yüzdesi(%), geri toparlanamama yüzdesi (%) ve elastik toparlanma yüzdesi (%) ölçümleriiçin Fyrma kumaş ekstensiyometresi kullanılmıştır. Kumaş tipi ve yıkama devirsayısı faktörlerinin elastan örme kumaşların esneme ve geri toparlanamamaözelliklerine etkisini incelemek amacıyla iki faktörlü ANOVA testi uygulanmıştır.
