摘　　要：介绍了腈纶废丝的碱法水解、酸法水解、加压水解3种水解方式及其工艺条件,腈纶废丝水解产物在制备新型功能纤维、离子交换纤维、高吸水性树脂、絮凝剂、采油堵水剂、印染助剂及粘结剂等方面的应用;指出了腈纶废丝的回收利用存在的一些问题;提出应强化腈纶废丝水解的研发,减少催化剂用量,控制回收成本,进一步拓宽水解产物的应用领域。Three kinds of hydrolysis process and their conditions for PAN fiber waste were introduced, namely alkali hydroly- sis, acid hydrolysis and pressured hydrolysis. The apphcation of the hydrolysis products of PAN fiber waste was reviewed in the fields of novel functional fiber, ion exchange fiber, super absorbent resin, flocculants, plugging agent for oil production, textile auxiliaries and adhesive. It was pointed out that the recovery of PAN fiber waste faced some problems and the research of PAN fi- ber waste hydrolysis process should be enhanced, the amount of catalysts be reduced, the recovery cost be controlled, the appli- cation field of the hydrolysis products be further widened.
