摘要(Abstract)：

分析了经三种不同工艺路线生产的缝纫线用高强低缩、低伸型涤纶长丝的物理性能与微观结构,指出了针对不同档次产品的需求,可以选用不同的工艺路线。
The properties and microstructure of high tenacity, low shrinkage and low elongation PET sewing yarn made by three different process routes were analyzed. It was pointed out the products with different quality level were produced by suitable process route.
