超声波技术在棉PLA织物退浆中的应用
Application of Ultrasonic Technology in Cotton PLA Fabric Desizing
摘要
Abstract
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 conventional 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 a-gent 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.关键词
