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.
