In this study an attempt has been taken to find out the influence of stitch length knit structure and yarn type on the pilling and abrasion resistance of major weft knitted single jersey fabrics The knit structures were selected as Plain Polo pique Single Lacoste and Double Lacoste made from Ne Cotton PC Polyester Cotton and CVC Chief Value of Cotton yarns with varying the stitch length of mm mm mm mm and mm The results revealed that smaller stitch length promotes both pilling and abrasion properties It was also found that pilling resistance of Double Lacoste structure was the highest in all types of yarns and stitch lengths although its abrasion resistance was the lowest Moreover the fabrics made from cotton yarns had better pilling performance than blended yarns but its abrasion resistance was the lowest among them
