Abstract—This research targets to remove fabric pill from spun polyester knitted fabric (pilling rate 1 out of 5) through laundering with a detergent containing alkaline cutinolytic esterase. After washing, fabric was graded for pilling rate, measured for color difference, and tested for weight loss and strength loss. Results indicated that fabric washed with detergent containing esterase had lower amount of pills (pilling rate 3-4) than that washed only with detergent (pilling rate 2-3). In addition, the former also showed better color appearance than the latter. However, the fabric weight loss and strength loss after washing with detergent containing esterase were slightly higher than that washing with only detergent.
Index Terms—Fusarium sp., cutinolytic esterase, laundry detergent, spun polyester, fabric pill.
