Abstract: Abstract：To improve the current situation that the traditional wool shrink-proofing process can not meet the ecological requirements, this paper focused on the shrink-resistant finishing of Gabardine and Valitin by the eco-friendly combination of H2O2/cutinase/protease. The results showed that the use of cutinase obviously enhanced the shrink-proofing effect. And the shrinkage rates of Gabardine and Valitin after finishing reached 0.25% and 6.5%, respectively, which had met the IWS standard of machine-washable. Moreover, results from the dye absorbing rate and alkaline solubility showed that relative to the sample treated without cutinase, the one treated with cutinase had higher dye absorbing rate and lower alkaline solubility, which suggested that cutinase could break the scales of wool surface to a higher extent. Thus, looser structure in the scales made the further treatment of protease take place more possibly in the scales, reducing the hydrolysis to woolen cortex by protease.
