摘要
将睛纶废丝在碱性条件下水解，经中和、洗涤后，加入交联剂甲醛反应，制得高吸水性树脂。实验表明，甲醛最佳用量为０．２２％左右，所得树脂吸水率稳定在６００～８００ｇ／ｇ。
Waste acrylic fibres were hydrolyzed under alkaline condition and cross-linking agent formaldehyde was added after neutralization and cleansing for reaction to get high water-absorption resin. Experiments showed that optimum use of formaldehyed was ablut 0.22% and resin water absorption gained was stabilized at 600-800g/g.
