聚乳酸纤维的碱处理及对染色性能的影响
Alkali treatment of polylactic acid fiber and its effect on dyeing
摘要
Abstract
The effects of sodium hydroxide concentration,reduction temperature and time on alkali treatment effect of polylactic acid fiber were studied,and the change of dyeing performance of polylactic acid fiber after alkali treatment was analyzed.The results showed that the reduction rate of polylactic acid fiber increased with the increasing of sodium hydroxide concentration,increasing of reduction temperature,expanding of reduction time,and the concentration of sodium hydroxide showed linear correlation.The strength of the fiber decreased obviously with the increasing of the reduction rate.After alkali treatment,dyeing percentage of polylactic acid fiber increased,but the color strength (K/S value) did not increase.In the actual production,the required reduction rate could be obtained by controlling the process conditions as required.关键词
