蜗牛酶在棉织物生物精练中的应用

探索了将蜗牛酶用作棉织物生物精练的可行性。首先,利用分光光度法分别测定了不同温度和pH值条件下蜗牛酶体系中纤维素酶、果胶酶及淀粉酶的酶活,优化了蜗牛酶体系的作用条件。其次,将蜗牛酶用于棉织物精练,考察了蜗牛酶处理对棉织物果胶去除率、棉蜡去除率以及减量率的影响。结果显示:在蜗牛酶质量浓度为15 g/L时,果胶去除率和棉蜡去除率分别达到50.7%和39.4%,减量率为4.2%。最后考察了蜗牛酶精练对织物润湿性能和白度的影响,结果显示,蜗牛酶处理可以大幅提高织物润湿性能,但是对织物白度的改善有限。

Application of Snailase in Cotton Fabric Bio-Scouring

The paper studied the possibility of the snailase in pre-treatment of cotton fabric. Firstly, the enzyme stability of snailase was studied in detail. The activity of cellulase, amylase and pectinase was determined under different pH and temperature. The process conditions for snailase complex wereoptimized. Secondly, gray cotton fabric was scoured by snailase in the optimal condition. Results showed snailase has a good effect on pectin and wax removal. When the concentration of snailase reached 15 g/L, pectin removal and cotton wax removal efficiency was about 50.7% and 39.4%, while the weight loss was 4.2%. At last, the scouring effect of snailase such as wetting time and whiteness was tested. The results showed that the wetting time of cotton fabric decreased quickly, while the whiteness changed slightly.
