Promotional Effect of Ionic Liquid on the Enzymatic Shrink-Resistant Finishing of Wool Fabrics

Article Preview

Abstract:

In the paper, wool samples were pretreated by [BmiCl ionic liquid, followed by protease. The effect of ionic liquid pretreatment on the enzymatic shrink-resistant finishing of wool fabrics was studied. The results showed that the epicuticle was damaged by pretreatment, and the wettability of wool fabric was improved. These changes of wool surface made a promotional effect on proteolytic reactions. They could remarkably improve the accessibility of protease and thus increasing the efficiency of protease treatment. The weight loss of the sample pretreated with ionic liquid was dramatically increased, and the encouraging shrink-resistance was also achieved after the combination of ionic liquid and protease treatments.
