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.

It is produced by a process similar to POY manufacturing except that the yarn is produced at higher spinning speeds coupled with intermediate drawing integrated in the process itself .this allows stabilization through orientation and crystallization.

DTY a is fully drawn, fully oriented polyester multi filament yarn with soft crimp, high bulk and texture with cotton feel and very high durability and retention properties. This is manufactured by texturing partially oriented yarn using texturing machines. DTY is suitable for fabric end uses like outer/inner garments, skin-clinging garments, furnishing and upholstery etc.
