ELASTAN İÇERİKLİ ATKILI ÖRME KUMAŞLARIN BAZI FİZİKSEL ÖZELLİKLERİNİN YIKAMA ÖNCESİ VE TEKRARLI YIKAMALAR SONRASINDA KARŞILAŞTIRILMASI

Öz

Bu çalışmada aynı elastan oranına sahip ancak farklı zemin ipliklerden üretilen düz örme kumaşların esneme (%), geri toparlanamama (%) ve elastik toparlanma özelliklerine yıkama tekrar sayısı ve kumaş tipinin etkisi incelenmeye çalışılmıştır. Düz örme 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 vorteks iplik, %100 pamuk ring iplik olarak seçilmiştir. Numuneler tekrarlı yıkama işlemine tabi tutulmuş olup her yıkama devri sonrasında sererek kurutma yapılmıştır. 1,5 ve 10 devir yıkama sonrası kumaş gramajları belirlenmiştir.  Numunelerin çubuk ve sıra yönlü esneme yüzdesi (%), geri toparlanamama yüzdesi (%) ve elastik toparlanma yüzdesi (%) ölçümleri için Fyrma kumaş ekstensiyometresi kullanılmıştır. Kumaş tipi ve yıkama devir sayısı faktörlerinin elastan örme kumaşların esneme ve geri toparlanamama özelliklerine etkisini incelemek amacıyla iki faktörlü ANOVA testi uygulanmıştır.

Comparison of the Selected Physical Properties of Elastane Weft Knitted Fabrics Before and After Repeated Launderings

Öz

It was aimed to investigate the influence of washing cycle and fabric type on stretching (%), unrecovered elongation (%) and elastic recovery properties of plain knitted fabrics made of different ground yarn types having the same elastane ratio (%). For the plain knitted fabrics; Elastane ratio was kept constant as 5% for all fabric types whereas the ground yarns were selected as 70% polyester 30% cotton vortex yarn, 70% polyester 30%viscon ring yarn, 70% polyester 30%cotton ring yarn, 100%viscon vortex and 100% cotton ring spun yarns respectively. Knitted samples were objected to repeated laundering and flat dried after each washing cycle. Fabric weight (g/m²) after the washing cycles of 1, 5 and 10 were premeasured. Fryma fabric extensometer device was used for determining the stretching ratios (%), unrecovered elongation (%) and elastic recovery (%) of the samples both in wale and course way. Two-Way ANOVA was performed in order to investigate the influence of washing cycle and fabric type on stretching (%) and unrecovered elongation (%) properties of the elastane knitted fabrics.
