摘要： 为了研究PTT/PET双组分长丝针织物布面不匀的问题，利用PTT/PET双组分长丝在无缝针织机上进行试织，通过无缝针织工艺的调整无法消除PTT/PET针织物布面这种随机性“条阴状不匀”,对PTT/PET双组分长丝结构及模拟织物整理工艺处理后的长丝结构进行研究，探明了该类长丝的“条阴状不匀”的成因，发现其左右螺旋且不断翻转的三维卷曲是布面“随机性条阴状不匀”的形成根源；通过改进纺丝工艺制得了新型PTT/PET双组分丝，从根本上消除了该类针织物布面的“随机性条阴状不匀”，且其织物布面均匀美观。

Abstract: To study the unevenness on the surface of PTT/PET plain knitted fabric, seamless knitted fabrics with PTT/PET were woven on trial basis. The “random strip unevenness” which couldn’t be eliminated by technical adjustments on the surface of PTT/PET plain fabrics was analyzed by studying the original configuration of PTT/PET and the configuration of PTT/PET after simulated finishing process. It was found that the three-dimensional endless spiral crimps of PTT/PET is the cause of “random strip unevenness”. Based on this, a new kind of PTT/PET filaments was made by improving the spinning process. The “random strip unevenness” was disappeared on the surface of knitted fabric made of the new PTT/PET filaments, and it appears uniform and aesthetic.
