摘　　要：采用LiCl/DMAc溶剂系统对活化处理后的棉纤维进行溶解,通过单因素试验和正交试验优化棉纤维的溶解工艺,分析棉纤维溶解过程中LiCl质量分数、溶质和溶剂质量比、温度和高温时间等的影响。结果表明:当LiCl质量分数为9%,溶质与溶剂质量比为1∶100,温度为110℃,高温时间为2.5 h,最后得到的溶解液均匀,颜色透明,溶解效果极佳。The activated cotton fiber is dissolved by LiCl/DMAc solvent system, and the dissolving process of cotton fiber is optimized by single factor test and orthogonal test. Effects of the mass fraction of LiCl, mass ratio of solute to solvent, temperature and reaction time at high temperature in the dissolving process of cotton fiber are analyzed. The optimized results show that when the mass fraction of LiCl is 9%, the mass ratio of solute to solvent is 1∶100, the temperature is 110 ℃, and the reaction time at high temperature is 2.5 h, the final solution is uniform and transparent, the dissolving effect is good.
