Application of Snailase in Cotton Fabric Bio-Scouring

Abstract:

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.
