【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。更多还原

【Abstract】 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 infrared 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 BTCA was proceeded.更多还原
