Savinase和木瓜蛋白酶处理对羊毛性能的影响

摘要

For improving the anti-felting effect of wool by enzymatic treatment, the wool samples that had been subjected to pretreatment with cutinase were treated with Savinase and papain, respectively. The effect of synergistic action of the two-step process on the weight loss of the samples was investigated. The experimental results revealed that under the same enzymatic concentration, Savinase treatment showed a little higher efficiency of enzymolysis and imparted the sample higher weight loss percentage than papain; under the same weight loss percentage, papain treatment rendered the sample better wettability, lower alkaline solubility and felting shrinkage than Savinase, indicating that the extent of scale removal was more remarkable during cutinase-papain treatment. The data obtained by XPS verified that papain seemed to degrade the scales more efficiently in hydrolysis mode than Savinase during wool enzymatic treatment.%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元素分析结果初步验证了木瓜蛋白酶较Savinase更趋于水解模式的羊毛酶解加工.
