本文探讨了PTT纤维的性能，并详细介绍了PTT弹性纱线筒子纱、PTT复合纤维面料以及PTT地毯等特殊PTT纤维产品的染整加工工艺。
This paper covers the properties of PTT fiber and in detail elucidates the dyeing and finishing process of PTT elastic yarn cheese, PTT composite fiber material and PTT carpet etc.
在高速络纱时，由于惯性作用，筒子的回转会导致纱线张力的波动。
At high winding speeds, due to inertia, the rotation of the spool may lead to tension variations in the yarn.
如果筒子质量对后道加工性能不利的话，纱线质量再好也没有多大意义。
The best yarn quality is of little use if the package quality adversely affects the downstream processing properties.
