利用等离子体并接枝麦芽糖提高聚丙烯布的亲水性

Hydrophilic Improvement of PP Fabric by Plasma and Grafting Maltose

为改善聚丙烯(PP)布的亲水性,先利用等离子体(空气,O2)预处理PP布使其表面引入反应性官能团;预处理之后,所引入的反应性官能团在架桥剂的存在下与麦芽糖反应,从而提高PP布的亲水性。试验所使用的架桥剂是乙二醇二缩水甘油醚(EGDE)和异氰脲酸三缩水甘油酯(TGIC)。结果表明:麦芽糖被成功接枝到PP布的表面,改性后PP布的亲水性在一定程度上得到了改善,并且在一定范围内能够被活性染料染色。

To improve the hydrophilicity of polypropylene （PP） fabric, the plasma of gas （Air, 02） is used for the pretreatment of PP fabric to produce reactive functional groups, then, the produced reactive functional groups on the PP surface are used to graft maltose in the presence of bridging agent in order to make PP fab- ric hydrophilic. The bridging agent is glycol diglycidyl ether （EGDE） and isocyanuric acid three glycidyl es- ter （TGIC）. The results show that maltose can be successfully grafted onto the surface of the PP fabric, the hydrophilicity of modified PP fabric is improved and the fabric can be dyed with reactive dye.
