Lin Kuo-lung elucidates: some makers use artificial gums in place of food-grade cornmeal for sizing, making the towels stickier the more you wash with them. And before dyeing, the fabric must undergo six hours of steaming in order to bleach it white and cook away the sizing agent; otherwise impurities will render the towel less absorbent.
林國隆指出，有人用人工膠材取代食用玉米粉來漿紗，結果越洗越黏；進行染色前的「漂白」時要高溫蒸煮 6 小時，徹底把漿紗煮掉，否則黏附的雜質會讓毛巾不吸水。
