摘　　要：通过差示扫描热分析仪(DSC)、干热收缩测试仪研究经编土工格栅原料聚酯长丝的结晶性能,分析热处理温度、时间对其热收缩性能、断裂强度、断裂伸长率及定伸长强度的影响。结果表明:热处理温度和时间对该长丝断裂强度的影响不明显,但对断裂伸长率和伸长强度的影响明显。The crystal properties of polyester filament for warp-knitted Geo-grids were studied by DSC and dry heat shrink apparatus. The effect of temperature and time of heat treatment on performance of heat shrinkage, intensity, break elongation and fixup-elongation intensity are also studied. The results show that the temperature and time of heat treatment have little influence on the intensity of the polyester filament, but have evident influence on break elongation and fixup-elongation intensity.
