摘　　要：为了解决腈纶废丝及废弃的废旧腈纶织物资源化及增值利用问题,通过溶剂溶解、碱水解、热处理将腈纶转化成了超级吸水材料。研究了溶剂、物料配比、反应时间、后处理方法等因素对产物吸水率的影响。实验结果表明,在适当的原料配比下,只需水解20min,即可制得吸水率300倍、甚至500倍以上的吸水材料。A novel process was proposed to produce superabsorbent from waste acrylic fiber. The fiber was dissolved in aqueous solution of sodium sulfocyanate and sodium hydroxide and hydrolyzed at elevated temperature.After reaction, water and ethanol were added which resulted precipitation. The solid was separated, washed and thermally treated to get the superabsorbent. The effect of the reaction parameters on the water absorbing capacity of the product was investigated. The product prepared at optimum conditions can absorb distillated water more than 300, even500g·g^-1.
