摘要/Abstract

摘要： 采用4种不同捻系数(280、320、360、400)的PTT短纤纱做为研究对象,对其主要力学性能(强伸性、拉伸回复性以及蠕变性能)进行了研究。通过纱线的强伸性能实验,初步得出了PTT短纤纱的临界捻系数范围在360左右;定伸长反复拉伸实验证明了PTT短纤纱具有良好的弹性回复性能;同时,由蠕变实验可以看到捻系数的大小对其弹性回复性影响不显著。并引入四元件模型对纱线的蠕变性能进行了模拟,模型拟合的参数与实验结果可以较好地吻合。

Abstract: The mechanical properties(action stretch,elastic recovery and creeping) of four kinds of PTT staple yarns with twist factor of 280,320,360,400 respectively were studied.Action stretch experiments of the yarns were performed and it was found that the critical twist factor of PTT staple yarn was around 360. Its good elastic recovery was demonstrated by constant rate of extension test and creep test showed that twist factor has insignificant effect on its elastic recovery.The creeping property of the yarn was analogized by a four-element analogous model and the result obtained is coincident with that of the experiment.
