摘　　要：以氯化1-丁基-3-甲基咪唑离子液体为溶剂对木质纤维素进行溶解并纺丝,得到再生纤维素纤维,再使用戊二醛对再生纤维素纤维进行交联改性,研究其交联改性条件对再生纤维素纤维力学性能的影响。结果表明:经戊二醛交联后,再生纤维素纤维的断裂强度有明显的提高;在戊二醛质量分数为4%,反应温度为50℃,反应时间为30 min的交联条件下,所得再生纤维素纤维的断裂强度为3.2 cN/dtex。Lignocellulose was dissolved using 1-butyl-3-methylimidazolium chloride ionic liquid＇as the solvent and spun into regenerated cellulose fiber, which was subjected to crosslinking modification in presence of glutaraldehyde. The effects of crosslinking modification conditions on the mechanical properties of regenerated cellulose fiber were studied. The results showed that the breaking strength of regenerated cellulose fiber was greatly improved after crosslinking modified with glutaraldehyde. The breaking strength of regenerated cellulose fiber was -3.2 cN/dtex when the crosslinking conditions were as followed： glutaraldehyde mass fraction 4%, reaction temperature 50 ℃ and time 30 rain.
