Effects of cutinase on the enzymatic shrink-resist finishing of wool fabrics
A novel microbial cutinase from Thermobifida fusca WSH04 was applied in the pretreatment of wool fabrics followed by protease treatment, aiming at improving the wettability of the samples by hydrolyzing the Outmost bound lipids in the wool surface. Cutinase pretreatment could increase the efficacy of the Subsequent protease treatment by improving the wettability, dyeability, and shrink-resistance of the wool fabrics. The data obtained by the XPS method showed the changes of elemental concentration in the wool surface after cutinase pretreatment. Compared with the fabrics treated with hydrogen peroxide and protease, the combination of cutinase and protease treatments produced better results in terms of wettability and shrink-resistance with less strength loss. The anti-felting property of the fabrics treated with the enzymatic resist-shrink technique is very promising to meet the commercial standard. (C) 2009 Elsevier Inc. All rights reserved.
