摘　　要：采用酸性纤维素酶对纯棉、粘胶、竹浆织物进行酶水解处理,分析比较了水解处理前后织物的质量、断裂强力、折皱弹性、硬挺度、悬垂性等性能变化。结果表明棉、粘胶、竹浆织物经酸性纤维素酶水解处理后,竹浆织物的水解失重率最大,其次是粘胶织物;酶水解作用后,棉、粘胶、竹浆织物的坚牢性、外观形态保持性均降低,粘胶织物断裂强力损伤最严重,棉、竹浆织物的断裂伸长、折皱回复性降低严重,竹浆织物的硬挺度损伤最大,同时棉、粘胶、竹浆织物的悬垂性均得到改善,纯棉织物的提高最为显著。Acid cellulase was used for the hydrolysis treatment of pure cotton, viscose and bamboo fabric. The weight and fabric properties of breaking strength, wrinkle recovery, stiffness and drapability before and after hydrolysis treatment were compared and analyzed. The results showed that pure cotton, viscose and bamboo fabric treated by the acid cellulase, the rate of weight loss of bamboo fabric was the largest, followed by viscose fabric. Both of the fastness and appearance retention were decreased, and the viscose fabric damage of breaking strength was the most serious. The elongation of break and crease recovery of cotton and bamboo fabric lost seriously, and the stiffness injury of bamboo fabric was the greatest. The drapability of three kinds of fabric were all improved, and the improvement of pure cotton fabric was the most notable.
