摘　　要：探讨超声波技术在棉PLA混纺织物酶退浆中的应用效果及退浆工艺优化。分别采用常规酶退浆与超声波酶退浆对棉PLA混纺织物进行退浆,比较了退浆后织物的退浆率、白度和经向断裂强力,并对超声波酶退浆条件下的酶浓度、双氧水浓度、精炼剂浓度、保温温度和保温时间及pH值进行了优化。试验结果表明:与常规酶退浆相比,超声波作用下的酶退浆可使棉PLA混纺织物的退浆率和白度明显提高,但断裂强力有一定程度下降;超声波作用下的酶退浆较理想工艺为退浆酶浓度5 g/L,双氧水浓度8 g/L,精炼剂浓度8 g/L,保温温度70℃、保温时间50 min,pH值7.5。认为,将超声波技术应用在织物酶退浆中具有节能减排的实际意义。Application effect of ultrasonic technology in cotton PLA blended fabric enzymes desizing and desizing processing optimization were discussed. Conventional enzymes desizing and ultrasonic enzymes desizing were adopted respectively on cotton PLA blended fabric. Desizing rate,whiteness and breaking strength in warp direction were contrasted. Enzymes concentration, hydrogen peroxide concentration, refining agent concentration, holding temperature, holding time and pH value in ultrasonic enzymes desizing condition were optimized. The test result shows that compared conven- tional enzymes desizing, desizing rate and whiteness of cotton PLA blended fabric are higher obviously when adopting ultrasonic enzymes desizing, while the breaking strength is reduced in certain degree. In ultrasonic enzymes desizing processing, the better processing should be enzymes concentration 5 g/L, hydrogen peroxide concentration 8 g/L, refining agent concentration 8 g/L,holding temperature 70 ℃ ,holding time 50 min and pH value 7.5. It is considered that significance of energy saving is larger by applying ultrasonic enzymes desizing technology.
