碱处理棉纤维结构及其在LiCi/DMAc中的溶解特性
Structure and dissolution characteristics in LiCl/DMAc of cotton cellulose after pretreated with NaOH solution
摘要
Abstract
Cellulose was pretreated with NaOH solution. Crystal structure changes of cellulose pretreated with different conditions were investigated, and the change of crystallinity and crystal size was characterized by X ray diffraction. The solubility and stability of solution of cotton cellulose after pretreated with NaOH solution. The results indicate that after pretreated, crystal structure of cellulose changed very obviously, X ray diffraction peaks of cellulose decreased very obviously, crystallinity and crystal size also changed, and changed very obviously with NaOH concentration, but the pretreatment temperature and time have little effect on the changes. Pretreated cellulose can dissolve in LiCl/DMAc, and can dissolve completely in LiCl/DMAc solution with 10% of LiCl concentration. Cotton cellulose/LiCl/DMAc solution begin to phase separation after 48 h, then formed gel, and separate out solvent.关键词
