Effect of Acid Wash on Appearance and Physical Properties of Terry and Interlock Knitted Dyed Garment

The closing step in finishing the garment manufacturing process involves washing, in particular for fashionable garments. Acid washing is a method used in garment finishing to make a valuable aesthetic for a garment. This study examines how two knitted garments—a terry (100% cotton) and an interlock (100% cotton)—are affected aesthetically and physically by acid washing using potassium permanganate and granular thermocol balls as an abrasive. Physical characteristics of the garments were examined after acid washing, and it was found that the garment weight in grams per square meter and spirality increased while their bursting strength reduced. Furthermore, colorfastness to wash, dry, wet rubbing, and pilling was unchanged. This work indicates that acid washing with thermocol balls is effective for making a faded look on terry and interlock garments for their value addition to customers.
