Investigation on Effect of Acid Wash with Thermocol Ball on Physical Properties of Knitted Garments

Washing is considered as the final process of garments finishing. Acid washing is one kind of finishing treatment used for making sewn garments aesthetic, fashionable, soft, comfortable and also adding value to the final garments. This paper investigates the effect of the acid washing (with thermocol balls and potassium permanganate) on different physical properties of three knitted garments (Single Jersey 100% Cotton T-shirt, Single Jersey 95% Cotton 5% Spandex T-Shirt and 1 × 1 Rib100% Cotton T-Shirt). Typical washing procedures and techniques were followed and then physical properties were analyzed under standard condition. It is observed that fabric weight, CPI, WPI, spirality and shrinkage increase while bursting strength, stitch length absorbency decrease after washing treatment. pH of all the samples is under controlled and lies between 7 to 8. There is no change in pilling, colorfastness to wash, water and dry rubbing while a little bit decrease in wet rubbing.
