Nylon POY

预取向丝（POY）(有光、半消光、全消光)

英文全称Pre-Oriented Yarn,在纺丝高速下，纤维产生一定的取向，结构较不稳定。其性能主要有伸长率偏大，一般都在60~72%左右；强度偏小，躲在3.7~4.0Cn/dtex之间；上色深等优点。POY是DTY的上一级原料，主要用于生产DTY。

The Pre-Oriented Yarn obtain a certain oriented during the high speed spinning and its structure is unstable.Its main features is a higher elongtation which is at 60-72% and a lower tenacity which is at 3.7-4.0 Cn/dtex,as well as the dyeing quality is deep. POY is raw material for Dty production.
