This paper deals with three types of washing (enzyme, softener, Silicone) effects on 100% cotton
Single Jersey T-shirt, Slub Single Jersey T-shirt, Double Lacoste (5% Lycra) Polo shirt, Single jersey
CVC (T-shirt) and PC single Jersey (T-shirt). Typical industrial washing procedures and techniques
were followed and then physico-mechanical properties were analyzed under standard condition.
It is observed that after washing, weight of each garments has increased from 5% to 36%; stitch
length of the constituted fabric has decreased from 1% to 10% approximately; CPI has increased
23% for CVC fabric only for enzyme treatment and for other process it has a little bit or no wash
effects. Same effects found for WPI except 100% cotton and Double Lacoste. Shrinkage property
both for lengthwise and widthwise remains the same except CVC and Double Lacoste knitted garments
and spirality has almost unchanged except 100% cotton and slub fabric. Both the dry and
wet rubbing properties have improved after any types of wash except 100% cotton on Silicone
wash. Water absorbency property has increased; pH of all the samples is under controlled and lies
between 4.5 and 5.0. But there is no significant change of colorfastness to wash and stain after
these washing treatments.
