摘　　要：为了提高TGase催化羊毛接枝ε-PLL的反应程度,分别采用H_2O_2、高锰酸钾、DCCA预处理羊毛织物,分析比较了TGase催化羊毛接枝ε-PLL的释氨量、接枝织物染色性能、抗菌性能、润湿性能差异及纤维表面形貌变化。结果表明,预处理羊毛可促进TGase酶促反应的发生,但经不同预处理的羊毛TGase催化接枝ε-PLL的效果不同,其中采用DCCA预处理效果最好,其氨态氮释放量可达1.748μg/mL,织物润湿时间最短,对金黄色葡萄球菌的抗菌效果也最好。高锰酸钾预处理次之,过氧化氢预处理效果相对较差。In order to enhance reaction degree of TGase catalyzing ε-PLL grafted onto the wool fabrics, hydrogen peroxide, potassium permanganate and DCCA were used to pretreat wool fabrics. The ammonia release, dyeing property, antibacterial property,wetting ability and surface morphology of ε-PLL grafted wool fabrics catalyzed by TGase were corn pared. The results revealed that pretreatment of wool fabrics could improve the enzymatic reaction, but different pretreatment had different effect. DCCA pretreated wool fabrics showed the best effect with an ammonia release amount of 1. 748 μg/mL, the shortest wetting time and the highest rate of inhibiting bacteria for staphylococcus aureus. Potassium permanganate pretreatment followed DCCA pretreatment,and hydrogen peroxide pretreated wool fabrics showed the worst effects.
