摘　　要：在纺丝液中添加聚马来酸和丁烷四羧酸,采用干喷湿法纺丝工艺制备了含有多元羧酸的莱赛尔纤维,研究了多元羧酸对莱赛尔纤维结构和性能的影响。结果表明,在纺丝液中添加多元羧酸制备的莱赛尔纤维截面孔隙分布不均匀,结晶度有所下降,可显著降低纤维的原纤化程度。其中,添加丁烷四羧酸制备的莱赛尔纤维几乎没有发生原纤化。Polymaleic acid and butane tetracarboxylic acid are added into the spinning solution,and Lyocell fiber containing polycarboxylic acid is prepared by dry spray wet spinning process.The results show that the cross-section pore distribution of Lyocell fiber prepared by adding polycarboxylic acid in spinning solution is not uni-form,the crystallinity is decreased,and the fibrillation degree of the fiber can be significantly reduced.Among them,the Lyocell fiber prepared by adding butane tetracarboxylic acid has almost no fibrillation.
