摘　　要：用ＳＥＭ，ＩＲ，ＤＳＣ等研究了聚醋酸乙烯（ＰＶＡｃ）醇解纺丝得到的聚乙烯醇（ＰＶＡ）纤维的形态结构、分子结构及热性能。用纤维电子强伸仪研究了纤维的力学性能。证明由ＰＶＡｃ醇解纺丝可得到强度和模量分别为１３．２７ｃＮ／ｄｔｅｘ和３５０．１０ｃＮ／ｄｔｅｘ的高性能ＰＶＡ纤维。The morphological, molecular structure and thermal properties of the PVA fibers obtained from PVAc alcoholysis spinning process were studied by means of SEM, IR and DSC. The mechanical properties of the fibers were determined by electron tensile tester. It was proved that PVA fibers with tensile strength 13.27 cN/dtex and modulus 350.10 cN/dtex can be obtained from PVAc alcoholysis spinning process.
