摘要
通过毡缩率、减量率、纱线强力等评价指标,探讨了预处理剂[H2O2、二氯异氰脲酸盐(DCCA)]对羊毛蛋白酶防毡缩整理的影响.结果表明:经H2O2预处理,毛纤维表面粗糙度增加,织物毡缩性加大,再经酶处理后织物的防毡缩效果改进较少;DCCA预处理可使毛织物的毡缩率下降,结合酶处理可进一步提高织物的防毡缩效果.此外,由于氧化(H2O2)与氯化(DCCA)对毛纤维表层结构反应的选择性不同,预处理+酶两步法处理后织物的减量率与毡缩性间的相关性也有差异.
Through evaluation of shrinkage, weight loss percentage and wool yarn strength, the influences of the preliminary agents [H2O2,dichlorinated isocyanurate （DCCA）] on shrink-resistance performance of wool fabric treated by proteases were studied. The results showed that the surface roughness of wool fibers was increased after H2O2-treated, and the felt of wool fabric was increased. Accordingly, the shrink-resistance effect of wool fabric was improved after enzyme treatment. DCCA pretreatment could decrease the index of shrinkage of wool fabric, and the shrink proofing effect of fabric could be further increased by combining with protease treatment. Furthermore, wool fabrics have different correlation between shrink-resistance and weight loss percentage after two steps treatment （DCCA pretreatment and enzyme treatment） because different surface structure reaction sites of wool were selected by oxidation （H2O2） and chlorination （DCCA）.
