摘要: 为提高羊毛酶法防毡缩整理效果,分别进行了基于角质酶预处理的羊毛Savinase碱性蛋白酶和木瓜蛋白酶加工,考察了二步法协同处理对羊毛减量效果的影响。研究结果表明,相同酶浓度条件下,Savinase较木瓜蛋白酶具有稍高的酶解效率,试样失重率较高;相同失重率条件下,木瓜蛋白酶处理羊毛较Savinase处理样具有稍好的润湿性,碱溶解度与水洗毡缩率也略低,表明角质酶、木瓜蛋白酶组合处理中羊毛纤维鳞片水解去除效果较好。XPS元素分析结果验证了木瓜蛋白酶较Savinase更趋于水解模式的羊毛酶解加工。

Abstract: The enzymatic treatments based on the combined use of cutinase and protease (alkaline protease of Savinase or papain) treatments were contrastively studied. The effects the two-step combined treatments on wool anti-felting were investigated. The results indicated that Savinase treatment was more efficient than papain treatment during wool processing, it led to more weight loss after wool enzymatic incubating. For the wool fabric treated with papain, when the weight loss was similar to that of the sample treated with Savinase, the wettability of the former was more satisfactory, the alkaline solubility and shrinkage percentage were also appreciably lower, revealing that the extent of scale removal was more remarkable during cutinase-papain treatment. The data obtained by the XPS method further showed that papain seems to degrade the scales more efficiently in hydrolysis mode than the protease of Savinase during wool enzymatic processing.
