Abstract:
In order to meet environmental requirerment, the aim of this study is to endow water repellency of wool fabric by using fluorine-free water repellent agent WS CONC., thus avoiding the potential risk for environment from fluoroalkyl compounds. The influence of concentration of water repellent agent WS CONC. and catalyst agent BC, curing temperature and time on water repellency of wool fabric was disscussed. Water contact angle was used to observe water rpellency of wool fabric. The results showed that the optimum finishing process was: 70 % take-up, fluorine-free water repellent agent WS CONC. 60 g/L, catalyst agent BC 60 g/L, curing at 170 ℃ for 70 seconds. After finishing, the initial water repellent level of wool fabric was 100, and 75 after 5 dry cleaning. The hand feeling of wool fabric was poor soft, color sightly yellowed, and strength increased.
