摘　　要：文章研究了利用超临界CO2流体对羊毛纤维进行预处理,再采用蛋白酶对羊毛纤维进行剥除鳞片处理,使羊毛纤维具有防毡缩性能。结果表明:经超临界CO2流体处理后,纤维的润湿性能明显提高;在相同的蛋白酶处理条件下,经超临界CO2流体预处理的羊毛纤维防毡缩性能提高,断裂强力下降较小。超临界CO2的最佳预处理条件为:压力15 MPa,温度80℃,时间30 min。This paper researched the wool that was pretreated by supercritical CO2 and shrink resistant finishing by enzymes.As the result,tbe fiber moistening was obvious raise after pretreated by supercritical CO2.When condition was the same,the shrink resistant of the wool treated with enzymes,was better than that one was not pretreated by supercritical CO2.The best condition of supercritical CO2 pretreated were pressure 15 MPa,temperature 80 ℃,time 30 min.
