摘　　要：文章采用纱线捻度仪对涤纶纤维的单次扭转极限进行测试,并在此基础上分析了纤维在不同扭转程度下的拉伸性能和拉伸弹性变化,结果表明扭转后的涤纶纤维其断裂强度、初始模量和断裂比功均有所减少;拉伸弹性中塑性变形减少,缓弹性变形增加,弹性回复率增大。This paper used yarn twist tester to test the single torsion limit of polyester fiber,and on this basis the tensile property and tensile elasticity of the fiber were tested under different torsion degrees.The results showed that the breaking strength,initial modulus and specific work of rupture of the twisted polyester fiber were decreased.In the tensile elasticity,the plastic deformation was decreased,the slow elastic deformation was increased and the elasticity was increased.
