摘要/Abstract

摘要： 摘要：为改变传统羊毛防毡缩整理不符合生态要求的现状，论文采用H2O2/角质酶/蛋白酶全生态组合方法对华达呢和凡立丁两种羊毛织物进行了防缩整理。结果表明，经H2O2预处理/角质酶处理/蛋白酶处理后，华达呢和凡立丁织物毡缩率分别为0.25%和6.5%，达到国际羊毛局机可洗标准，角质酶的使用显著的提高了防缩效果。上染速率曲线和碱溶解度测试结果表明，与无角质酶处理相比，H2O2/角质酶/蛋白酶处理后试样的上染速率更快，碱溶解度略有减少，说明角质酶可能使羊毛鳞片层更疏松导致后续的蛋白酶处理有一种类似定向的作用，促使蛋白酶更多的集中处理了鳞片层，在一定程度上减少了蛋白酶对羊毛皮质层的水解。

Abstract: Abstract：To improve the current situation that the traditional wool shrink-proofing process can not meet the ecological requirements, this paper focused on the shrink-resistant finishing of Gabardine and Valitin by the eco-friendly combination of H2O2/cutinase/protease. The results showed that the use of cutinase obviously enhanced the shrink-proofing effect. And the shrinkage rates of Gabardine and Valitin after finishing reached 0.25% and 6.5%, respectively, which had met the IWS standard of machine-washable. Moreover, results from the dye absorbing rate and alkaline solubility showed that relative to the sample treated without cutinase, the one treated with cutinase had higher dye absorbing rate and lower alkaline solubility, which suggested that cutinase could break the scales of wool surface to a higher extent. Thus, looser structure in the scales made the further treatment of protease take place more possibly in the scales, reducing the hydrolysis to woolen cortex by protease.
