Research progress in modification technology for hygroscopic polyacrylonitrile fiber

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 technolgies included hydrophilic group introduction by polymerization and copolymerization,grafting copolymerization with hydrophilic material,alkali decrement 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.
