以常规聚合度聚合的乙烯醇（PVA,聚合度1 700～2 600）为原料,以二甲基亚砜（DMSO）为溶剂,乙醇为凝固剂,甲醇为萃取剂,采用干湿法纺丝制备高强度的PVA纤维,最高强度可以达到19.4 cN/dtex。使用扫描电子显微镜对PVA纤维样品进行观测,纤维样品的形貌结构十分均匀,这对提高PVA纤维的断裂强度十分有利。

Polyvinyl alcohol fibers with a high tensile strength reaching to 19.4cN/dtex is produced by dry-jet wet spinning,In the spinning process the conventional polymerization degree PVA（the degree of polymerization is between 1 700 and 2 600）,dimethyl sulfoxide（DMSO） as the solvent,ethanol as the coagulator,and methanol as the extractant are used.The homogeneous morphology of the fiber samples can be found through scanning electron microscope,and it is helpful for raising PVA fiber＇s tensile strength.
