摘　　要：用KES测试分析了PTT的短纤织物、DTY长丝织物和PTT/PET双组分并列复合长丝织物的弹性伸长率、弹性回复率、塑性变形及抗疲劳特性,并且将其性能与氨纶、普通化纤织物(涤纶、锦纶织物)进行比较发现,PTT各种形态织物的弹性伸长均比普通化纤织物的弹性伸长大,比氨纶织物的弹性伸长小;在低负荷下,其回复性能均比普通化纤织物小,塑性变形比普通化纤织物大;3种形态的PTT针织物中PTT/PET双组分并列复合长丝织物的弹性伸长最大,回复性能最好,PTT短纤织物的回复性能最差,塑性变形最大。KES was used to test the elastic extension, elastic recovery, plastic deformation and fatigue resistance of three kinds of fabrics made from PIT staple fiber, DTY and PTT/PET bicomponent fiber respectively and they were compared with those of urethane elastic fiber fabric and the common chemical fiber fabrics （PET and nylon）. It is found that the elastic elongation of all kinds of PTT fabric is longer than that of common chemical fiber fabrics, but less than that of urethane elastic fiber fabric; under low load condition, the PTT fabrics exhibit lower recovery and higher plastic deformation than the common chemical fiber fabrics; among the three kinds of PTT fabrics, PTT/PET fabric shows the maximum elastic elongation and the best stretch recovery, while PTT staple fiber fabric shows the lowest stretch recovery and highest plastic deformation.
