摘　　要：用不同醇解度的聚乙烯醇进行冻胶纺丝 ,得到了醇解度为 99 5 %、93%、86 %的聚乙烯醇纤维 ,研究了不同醇解度下纤维中的氢键及其对纤维力学性能的影响。结果表明 ,相对较低的醇解度可以有效控制纺丝过程中氢键的形成 ,提高易拉伸性和纤维的力学性能。Spun poly (vinyl alcohol) with different degrees of alcoholysis by gel-spinn ing method and drew them,then got a series of PVA fiber with alcoholysis degree 99.5%,93% and 86%.Analyzed these fibers with FT-IR and NMR,and measured the stren gth of them.The results showed that partially alcoholized PVA with lower degree of alcoholysis could decrease the chance of H-bond formation,and increase dr aw ability and fiber strength.
