固定化中性蛋白酶在羊毛针织物防毡缩处理中的应用

研究了用固定化中性蛋白酶进行羊毛针织物防毡缩处理工艺,进行了单因素分析实验,通过正交试验确定了固定化中性蛋白酶处理工艺参数。结果表明:固定化中性蛋白酶用量5%(owf),温度50℃,pH值7.0,处理时间60 min时处理效果较好。比较了游离蛋白酶与固定化蛋白酶用于羊毛针织物的防毡缩整理试验,固定化蛋白酶处理羊毛针织物防毡缩效果提高37.6%,失重率降低45.2%,强力损伤降低52.7%,白度提高23.2%,起毛起球提高了2级,这将为羊毛针织物防毡缩整理用酶奠定基础。

Study on the immobilized neutral proteinase on shrink-resist finishing of wool fabrics

In this paper,we researched the technology of the shrink-resist finishing of wool fabrics with the immobilized neutral proteinase,prcessed the single-actor experiment.The application technological parameter of the immobilized neutral proteinase was optimized by the orthogonal experimental design.The result showed that the amount of the immobilized neutral proteinase was 5%(owf),the treating temperature was 50 ℃,the treating pH value was 7.0 and the treating time was 60 min.The results finishing the wool fabrics with the free and immobilized neutral proteinase were compared.The result showed that the shrinkage effect was increased 37.6%,the weight loss percentage was descended 45.2%,the strength loss percentage was descended 52.7%,the whiteness was increased 23.2% and the anti-pill rate was raised by level 2.This will establish the basis of the industrializing enzyme on shrink-resist finishing of wool knitted fabrics.
