摘　　要：将超声波技术应用于聚乳酸/棉织物酶退浆处理,比较常规酶退浆工艺与超声波工艺对聚乳酸(PLA)纤维性能的影响,并通过单因素试验优化了超声波酶退浆工艺:双氧水8 mL/L,精练剂4 g/L,退浆酶5 g/L,处理液pH值7.5,超声波频率45 Hz。在超声波作用下,生物酶前处理织物退浆率提高(减重率提高15%),白度提高20%以上。Ultrasonic technique is applied to the enzyme pretreatment of PLA fabric. The effect of conventional enzyme desizing process and ultrasonic process on PLA fabric performance are compared. The optimum conditons of enzyme desizing process assisted with ultrasonic technique are： hydrogen peroxide 8 mL/L, scouring agent 4 g/L, desizing enzyme 5 g/L, pH ？. 5, ul- trasonic frequency 45 Hz. The weight loss rate of the pretreated fabric increases by 15%, and the whiteness increases by a- bove 20 %.
