| Abstract: | The research progress in high-performance polyvinyl alcohol (PVA) fiber was reviewed in recent years. The production technologies of PVA with ultrahigh relative molecular weight mass and high stereo-tacticity were introduced. The gel spinning process of high-performance PVA fiber was described, and the influential factors including fiber structure, drawing process, solvents, coagulant varieties and coagulation bath temperature, etc. were discussed. The developing trend and application prospects for high-performance polyvinyl alcohol fiber were predicted. It was pointed out that the development of PVA fiber should be focused on high polymerization degree and high stereo-tacticity. |
