摘要
综述了国内外吸湿性聚丙烯腈(PAN)纤维的研究现状;阐述了PAN纤维的吸湿机理及影响吸湿性的因素;详细介绍了改善PAN纤维的吸湿性的化学方法和物理方法;PAN纤维吸湿改性化学方法有通过聚合和共聚引进亲水基团、与亲水物质接枝共聚、对纤维表面进行碱减量处理、纤维表面的亲水整理、等离子体处理等;PAN纤维吸湿改性物理方法有与亲水性物质共混、纤维结构微孔化、纤维截面异形化和表面粗燥化等;指出开发吸湿性能好、服用舒适的PAN纤维是今后PAN纤维的主要发展方向。
The research status of hygroscopic polyacrylonitrile （PAN） fibers was reviewed in China and abroad. The hygroscopic mechanism and the influential factors bearing upon the hygroscopicity of PAN fiber were described. The chemical and physical technologies for improving the hygroscopicity of PAN fiber were introduced in details. The chemical teehnolgies included hydrophilic group introduction by polymerization and eopolymerization, grafting copolymerization with hydropbilic material, alkali dec- rement treatment or hydrophilic finishing on the fiber surface, plasma treatment. The physical technologies included blending with hydrophilic material, fiber micropore formation, fiber cross section shaping, fiber surface roughening. It was pointed out that the development trend of PAN fiber should be focused on PAN fibers with favorable hygroscopicity and clothing comfort.
