摘要
用６０Ｃｏγ射线研究了丙烯酸在聚酯短纤维织物上的辐射接枝共聚反应。探索了单体浓度、辐射剂量、阻聚剂等对接枝率的影响，并且测试了所得接枝物的吸湿性、染色性和物理机械性能。随着接枝率的大幅度提高，纤维织物的吸湿性和染色性有明显的提高，但纤维织物的机械性能将有所下降。
Radiation graft of acrylic acid on polyester staple fibre has been studied by using γ radiation of 60 Co to obtain hygroscopicity. The effects of monomer concentration, irradiation dose and the type of polymerization inhibitor were investigated. The results show that the hygroscopicity and dyeability improve significantly with the big increase of grafting rate, while the mechanical strength of the fabric lowers somewhat.
