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 used primarily in texturizing to make textured yarn (DTY). The filaments are stretched or drawn up to five times their original size during the spinning process 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. As a result, POY is generally had lower tenacity and less uniform than fully oriented yarn (FOY). Additionally, POY can also use in draw warping for weaving and warp knitted fabrics.
POY yarn is available in different luster, for example, semi-dull POY, full dull and bright POY. The bright POY has shininess due to the filaments' cross-sections. The fabric is made from bright POY also has a bright luster.
Polyester POY is mainly available in raw white color and various colors. The Dope-Dyed technology has much more efficient when colors on POY and the yarn gets evenly colored at every part. Color master-batch is mixed with the raw material to make the dope-dyed POY. Dope-dyed POY can be used to make the Dope Dyed DTY yarn.
Recycled Polyester Partially Oriented Yarn is made from R-Pet and recycled plastic bottles. It is such a great way to divert plastic waste from landfills. In addition, 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 yarns. 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.
