魔芋多糖基活化剂在棉织物低温漂白中的应用
Application of konjac glucomannan-based activator in low-temperature bleaching of cotton fabric
摘要
Abstract
The konjac glucomannan-based activator synthesized in the lab was used as the low-tempera-ture bleaching auxiliary agent of hydrogen peroxide for cotton fabrics.The bleaching process was optimized by evaluating the influence of various conditions on bleaching performances of cotton fabrics and the activation mechanism of bleaching activator was also systematically investigated.The results indicated that the optimal bleaching process was as follows:activator 4 g/L,NaOH 50 mmol/L,temperature 70℃,time 60 min.The bleaching activator could promote the production of hydroxyl radical(HO·)and effectively reduce the bleaching temperature.The cost calculation results revealed that the application of bleaching activator could significantly reduce the production cost in terms of reagent consumption and energy consumption.关键词
