The Combined Use of Cutinase, Keratinase and Protease for Wool Bio-antifelting

摘要：

In this paper, a cutinase from T. fusca and a keratinase from B. subtilis were applied to the enzymatic pretreatment of wool followed by protease treatment, respectively, aiming at improving the anti-felting property of wool without obvious fibre damages. The results demonstrated that cutinaseprotease process presented better wettability and shrink resistance to wool than keratinase-protease process and individual protease treatment. The combined use of cutinase, keratinase and protease treatments endowed wool fabrics with more satisfactory properties, including better wettability, lower area shrinkage with acceptable strength loss. This could be attributed to that cutinase pretreatment partially removed the hydrophobic lipids from wool epicuticle, simultaneously increased the accessibility of keratinase towards the substrate of disulphide cross-linkages, making the subsequent proteolytic reactions efficiently occur in the wool scales.
