摘　　要：采用Nexus 870傅立叶红外光谱分析仪和DSC热分析仪分析水溶性维纶纤维的化学结构和热学性能.同时,采用单纤维强力仪测试水溶性维纶纤维的力学拉伸性能.得到水溶性维纶纤维及其在80℃的水中溶胀后试样玻璃化温度分别为43.6℃和-2.2℃;水溶性维纶纤维红外光谱图与标准聚乙烯醇红外光谱图在波数1 236cm-1和621cm-1处存在明显差别;单纤维拉伸速度一定时,试样夹持长度小,单纤维的断裂强度略大、断裂伸长率大、断裂功小.The chemical structure of water-soluble polyvinyl alcohol fiber is tested and compared with standard polyvinyl alcohol by using Nexus 870-FTIR. Using TA 2910 DSC tests the thermo-property of water-soluble polyvinyl alcohol fiber. Using YG001N single-fiber tensile tester tests the tensile properties of water-soluble polyvinyl alcohol fiber. It is got that the glass temperature are 43.6℃ and -2.2 ℃ of water-soluble polyvinyl alcohol fiber and its solution swelled sample at 80℃ water, respectively. The IR has a difference at 1 236cm^-1 and 621cm^-1 for water-soluble polyvinyl alcohol fiber and standard polyvinyl alcohol. At tensile speed is constant, the fiber breaking strength and breaking elongation increases, and breakage work decreases when fiber length between two grasps is short.
