Polyester DTY (Draw Textured Yarn) is produced through the false twist texturizing process, which involves simultaneous drawing and twisting of the yarn. More specifically, DTY is the result of a secondary texturizing process using friction discs applied to POY (Partially Oriented Yarn) under heat and tension, leading to changes in the yarn's appearance.
This process reduces the elongation of POY and imparts crimp and waviness to the yarn. The main goal is to achieve physical and visual characteristics similar to natural fibers. DTY yarn is commonly used in men’s shirts, women’s coats, warp knitting, car seat covers, upholstery fabrics, and floor coverings such as carpets and rugs.
