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. 

Anahtar Kelimeler

düz örme kumaş, elastan, yıkama devir sayısı, uzama yüzdesi (%), geri toparlanamama yüzdesi (%), elastik toparlanma (%)

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.
