摘要
选用Savinase蛋白酶对羊毛织物进行防毡缩处理,采用非氯氧化剂——双氧水作为前处理剂,通过Savinase蛋白酶酶活测试,确定初步的实验参数,采用单因素分析和正交试验相结合的方法,确定Savinase蛋白酶防毡缩整理的最佳工艺为:蛋白酶用量3%(owf)、p H值7、温度55℃,时间40 min、浴比1∶30。实验结果表明,Savinase酶对羊毛织物防缩整理可使羊毛缩率下降到5.60%,由此得出,Savinase蛋白酶整理可使羊毛织物获得较好的防缩效果。
In this paper, Savannas protease is selected to treat wool fabrics for shrink-resistance. It is studied that the effect of the non-chlorine oxidant H202 for pretreatment on protease treatment of the wool fabrics. It got the preliminary experimental parameters through testing of enzyme activity. Used two methods of single factor analyzed and multilevel orthogonal design to get the best process parameters： protease dosage 3% （owf）,pH value 7, temperature 55 ℃,time 40 rain,bath ratio 1：30. The result showed that the shrinkage of the treated fabric has reduced to 5.60% . As a result, protease treatment renders wool fabric good shrink resistance.
