摘　　要：为降低传统的羊毛防毡缩整理工艺对环境的污染,研究了氩气低温等离子体(LTP)及蛋白酶/LTP复合处理的方法对羊毛织物的防毡缩整理.通过测定羊毛织物的毡缩率、等离子体电子密度等,结合电镜观察羊毛纤维表面鳞片的变化情况,讨论了LTP的作用原理.结果表明:以LTP处理羊毛织物时,电子密度随功率或压强的增大而增大,当功率和压强保持一定,电子密度不随时间变化;LTP对羊毛纤维的刻蚀程度随功率增大、时间延长而增强;MG酶/LTP复合整理优化条件为MG酶浓度0.8 g/L,LTP功率250 W,压强35 Pa,时间5 min,处理后羊毛织物毡缩率为2.28%,此种复合的整理工艺提高了单一工艺处理的效果,达到国际羊毛局机可洗标准.To reduce the pollution of traditional wool shrink-proofing process to the environment, this paper focused on the wool fabric modification with LTP （low temperature plasma） in argon, and protein enzyme/LTP compound treatment for shrink-proofing. By means of the measurement of shrinkage rate of the fabric, electron density of the plasma and through the observation of the scales of wool , the effect of LTP to the fabric was discussed. The results showed that the elec-tron density increased when the power or the pressure of LTP treatment increased, but it didn＇t change with time on a given condition of the power and the pressure. The etching extent on surface of wool fibers could be enhanced by the increase of power and time. The optimum conditions of protein enzyme/LTP compound treatment were obtained as the following, the Protex Multiplus G concentration is 0.8 g/L, LTP power is 250 W, pressure is 35 Pa and treatment time is 5 min. The shrinkage rate of finished wool fabric could attain to 2.28 %, which is better than that of singular treatment and meets the IWS standard of machine-washable.
