China Supplier 4ply Sock Yarn - Nylon Partial Oriented Yarn for Weaving and Warp Knitting – JIAYI

What is FDY?

Nylon partially oriented yarn, which is commonly known as nylon POY, is produced from the melting and extrusion (melt spinning) of the PA6 chip.  During the spinning process the filaments are stretched or drawn as much as five times their original size to orient the polymer to meet the desired evenness, strength, shrinkage, and elongation properties.  Therefore the term partially oriented yarn refers to multi-filament that is only partially stretched. POY is generally lower strength (3.7-4.0Cn/dtex) and larger elongation( about 65-72%) when compare with fully drawn yarn (FDY).
