What is Partially Oriented Yarn (POY)?
Partially oriented yarn is produced from the melting and extrusion (melt spinning) of the polyester chip or flake. 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.
So the term partially oriented yarn refers to multi-filament that is only partially stretched. POY is generally lower tenacity and less uniform than fully oriented yarn (FOY). POY is mainly used in texturizing to make textured yarn and can also be used in draw warping for weaving and warp knitting of fabrics.
