摘　　要：以甘蔗渣为原料,通过醚化处理,并以N,N’-亚甲基双丙烯酰胺为交联剂,制取醚化交联甘蔗渣纤维。其制备工艺为:碱液用量10mL;碱液浓度40%;碱化时间1.5h;交联剂用量为原料用量的7%;碱醚比2.5∶1(摩尔比);无水乙醇溶剂用量25mL。醚化交联甘蔗渣纤维的最高吸水倍率为52.8g/g。Cross-linked etherification bagasse fiber was produced by etherification and crosslinking way. Property of absorbing water and holding water for the bagasse fiber were discussed. Etherification and crosslinking condition was defined as： sodium hydroxide 40%, 10 mL, alkalified time 1.5 h, the amounts of crosslinking agent 7%, the ratio of sodium and etherification 2.5 ： 1 （mol/mol）, ethyl alcohol dosage 25 mL. Results showed that water absorbability of the etherification and crosslinking fiber could reach 52.8 g/g.
