Abstract
Wool gabardines were treated with alkaline proteases, and their tensile strerigth and dyeing behavior were obtained. Enzylon ASA 30 and Alcalase 2.5L DX did not show much effect on the weight loss of wool, but Esperase 8.0L decreased the weight of wool to a great extent. Pretreatment of wool with dichloroisocyarturic acid before protease-treatment increased the weight loss of wool considerably. Weight loss was accompanied by serious strength decrease and the use of sodium sulfate in the protease-treatment had not effect on the strength retention, only lowering the weight loss of wool. Protease-treatment of wool increased dyeability considerably, which may be due to the change in the inner structure of wool fiber by protease.
