摘　　要：为提高羊毛表面的亲水性,利用氯化1-丁基-3-甲基咪唑离子液体对羊毛角蛋白的良好溶解能力,将其用作羊毛蛋白酶预处理。将离子液体预处理和蛋白酶处理联合,完成对羊毛表面的亲水化改性。结果显示,离子液体预处理对羊毛蛋白酶法处理后纤维的润湿性能有明显促进作用。经过联合处理后,织物润湿时间下降,纤维吸水量增加,润湿接触角测试显示织物表面自由能降低。通过减量率测试和XPS分析可以看出,离子液体预处理有效促进了蛋白酶对纤维的水解效果,预处理后纤维表层亲水性基团增加,促进了织物润湿性能的提高。In order to improve the wettability of wool,an ionic liquid（IL）1-butyl-3-methylimidazolium chloride which has a good solubility for wool keratin was employed as a pretreatment step in protease processing for the hydrophilic modification of wool.The effect of IL pretreatment combined with protease process on the wettability of wool fibers and fabric was analyzed through wetting time,water uptake and contact angle tests.The results revealed that IL pretreatment could sufficiently improve the efficiency of protease processing.The wettability of wool samples after the combined treatments was improved.The water wetting time and contact angle of wool fabric decreased quickly while water uptake of wool fibers increased.The tests of weight loss and XPS showed that IL pretreatment improved the hydrolyzation efficiency of protease,and thus inducing more hydrophilic protein groups exposed.
