摘　　要：探讨了二氯异氰尿酸盐(DCCA)、蛋白酶、MTG酶处理对羊毛纤维强力、碱溶解度和摩擦因数的影响。结果表明:DCCA和蛋白酶处理使得羊毛纤维强力明显下降、碱溶解度增加,使羊毛纤维受到一定程度的损伤。经DCCA和蛋白酶处理后再用MTG酶处理,纤维强力提升至原样的98.9%,碱溶解度降低了20.59%,揭示了MTG酶通过催化纤维大分子交联而起到一定"补强"作用。总体而言,MTG酶处理使得纤维DFE值增加。The effects of DCCA,protease,MTG enzyme on wool breaking strength,alkali solubility and friction coefficient were studied.The strength and alkali solubility of the wool fibers decreased after the DCCA and protease treatment,indicating that the wool fibers suffered certain damage.The strength could be increased to 98.9% of the blank sample and the alkali solubility was decreased by 20.59%,which revealed that the MTG enzyme has a function of strength recovery through catalyzing the cross-linking of fiber macromolecules.In addition,MTG enzyme treatment would generally improve the DFE（directional friction effect） values.
