(POY)
Polyester Partially
Oriented Yarn
Polyester Partially Oriented Yarn (POY) is produced from the melting and extrusion of the polyester chip or flake, made directly from PTA and MEG by using spinning and take-up process and mainly used in texturizing to make textured yarn (DTY). During the spinning process the filaments are stretched or drawn up to five times of 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 tenacity and less uniform than fully oriented yarn (FOY). Additional, POY can also be used in draw warping for weaving and warp knitting of fabrics.
HOW MANY LUSTERS?
POY yarn is available in different luster, for example, semi-dull POY, full dull and bright POY. The bright POY has the shininess in itself due to the cross-sections in the filaments. The fabric which is made from bright POY also has the bright luster.
HOW MANY COLORS?
Polyester POY yarn is mainly available in raw white color and also available in various different colors. POY is usually colored by the Dope Dyed technology as it is more efficient and the yarn gets evenly colored at each and every part. Color master-batch is mixed with the raw material to make the dope dyed POY. Dope dyed POY yarn can be used to make the Dope Dyed DTY yarn.
Recycled Polyester
Partially Oriented Yarn
Recycled polyester partially oriented yarn is made from recycled polyester, often called R-Pet, which is made from recycled plastic bottles. It is a great way to divert plastic waste from our landfills. The production of recycled polyester requires fewer resources than new fibers and generates fewer CO2 emissions.
There are 2 ways to recycle polyester. Firstly, for mechanical recycling, plastic is melted to make new yarn. This process can be done a few times before the fiber loses its quality. Secondly, chemical recycling involves breaking down the plastic molecules and reforming them into yarn. This process maintains the quality of the original fiber and allows the material to be recycled infinitely, but it is more expensive than the first process.
