| 摘 要： | A process for the shrink - resist treatment of wool by protease with a hydrogen peroxide pretreatment (the Perzym process) has been studied. A protease, selected from several commercial proteases, has been found having higher activity in shrink - resist treatment, and its optimum technological conditions, which confer wool better shrinkproofing and less strength and elongation loss, have been obtained by an orthogonal factorial design approach. The study shows that it is possible for the wool to be conferred excellent machine washability by the Perzym process.
