摘　　要：以Co60γ射线为辐射源,对聚丙烯纤维在空气中进行辐照,然后将样品置于丙烯酸水溶液体系中进行接枝反应,研究了辐射剂量、反应温度、反应时间等对接枝率的影响以及纤维的力学性能.结果表明:随着辐射剂量的增加,接枝率明显提高;70℃左右为最佳反应温度;接枝后的纤维仍有较好的力学性能.PP fibers are preirradiated by γ ray from Co^(60) in the air. The PP fibers are immerged into the solution of acrylic acid for grafting reaction. The influence of the preirradiation dosage, the reaction temperature, and the reaction time on the graft efficiency are studied. The mechanics performance of the fibers is also studied. The research shows that along with the increase of preirradiation dosage, the graft efficiency has obvious raising, the best reaction temperature is 70 ℃, and the fiber after grafting still has better mechanics performance.
