摘　　要：采用阴、阳离子交换树脂处理Ｌｙｏｃｅｌｌ纤维纺丝凝固浴,纯化回收凝固浴中的溶剂ＮＭＭＯ。研究结果表明,阴离子交换树脂脱色效果好,阳离子交换树脂能去除ＮＭＭＯ的分解产物吗啉和甲基吗啉,用回收后的ＮＭＭＯ作为溶剂纺出的纤维性能良好。The purification of the coagulation bath of Lyocell fiber and regeneration of NMMO using ion exchange resin were discussed. The results show that the anion exchange resin can effectively discolor the coagulation bath and cation exchange resin can remove decomposition products of NMMO. The properties of fiber which is made by recycle NMMO are almost equal to the one which is made by virgin NMMO.
