摘　　要：研究了LiCl/DMAc(氯化锂/二甲基乙酰胺)体系溶解纤维素浆粕的最佳工艺条件,加入交联剂丁烷四羧酸(BTCA)、催化剂次亚磷酸钠(SHP)制成纤维素溶液并制得纤维素膜;对该膜进行了红外光谱、断裂强力、折皱回复角和透湿性测试分析。结果表明纤维素膜与BTCA发生了交联反应,并明显提高了纤维素膜的抗皱性能。The cellulose pulp were dissolved using LiCl/DMAc system. The crosslink agent BTCA and catalyst SHP were added into the solution. The cellulose membranes were prepared from the cellulose spinning solution. The Fourier infrated spectroscopic （FT-IR）, tensile strength, crease recovery angle and moisture permeability of the cellulose films were tested and analyzed. The results showed that the anti-crease property of cellulose film was improved and the crosslinking reaction between cellulose film and BT- CA was proceeded.
