摘　　要：采用低聚马来酸(PMA)和柠檬酸(CA)作为混合交联剂处理Lyocell纤维,以克服其易于原纤化的缺点,使其具备较强的抗原纤化性能。系统研究了PMA-CA的交联条件对Lyocell纤维抗原纤化性能及力学性能的影响规律,得到了PMA-CA与Lyocell纤维交联后处理的最佳实验条件;改性后的Lyocell纤维抗原纤化性能提高16.8倍,断裂强度只下降10.3%。红外光谱表明Lyocell纤维与PMA-CA发生了酯化反应,形成了网状交联结构,从而使Lyocell纤维的抗原纤化能力明显提高。Polymeric maleic acid(PMA)and citric acid(CA)was used as mixed crosslinking agent in crosslinking treatment for enhancing anti-fibrillation property of Lyocell fibers.The influence of PMA-CA crosslinking treatment conditions on anti-fibrillation property and mechanical property of Lyocell fibers was studied,and the optimal experimental conditions of cross-linking treatment of PMA-CA and Lyocell fiber were obtained.The anti-fibrillation property of Lyocell fibers is increased by 16.8times and the tenacity is decreased only 10.3%.FT-IR results indicate that the esterification reaction of Lyocell fibers take place and anti-fibrillation property of the Lyocell fiber is significantly improved.
