Lyocell短纤维聚集态结构的测试研究

A Study on the Supermolecular Structure of Lyocell Staple Fiber

采用傅立叶变换红外吸收光谱(FTIR)、广角X射线衍射(WAXD)、小角X射线衍射(SAXD)、扫描电镜(SEM)、密度梯度、贝瑞克法和氮气吸附等近代测试方法,研究了溶剂纺干湿法再生纤维素纤维Lyocell的聚集态结构,发现了Lyocell短纤维具有的新特点.并较为详尽地分析了其特点.

By using a few modern test methods including FTIR,WAXD,SAXD,SEM and so on ,the supermolecular structure of solvent spinning regenerated cellulose staple fiber that named Lyocell by BISFA was studied in detail.Simultaneously,new characteristics of Lyocell staple fiber were discovered and analyzed.
