摘要
以聚丙烯纤维为基体,以丙烯酸(AA)为单体,在石英大试管内通过紫外光照射,使丙烯酸单体接枝到纤维表面,研究了一些因素对纤维的接枝率和回潮率的影响。实验结果表明:光敏剂浓度为0.25mol/L,浸泡时间为1.5h,单体浓度为0.9mol/L,光照时间为2.25h时,聚丙烯纤维的接枝率和回潮率较高。
The graft copolymerization of acrylic acid onto polypropylene fiber was studied by photochemical initiation in the quartz test tube. The grafting percentage and moisture regain of the polypropylene fiber is greatly influenced by the some factors. The results show that the optimum reaction conditions are as follows： the photosensitizer concentration 0.25 mol/L, the soak time 1.5h; the monomer concentration 0.9mol/L, the irradiation time 2.25h.
