DTY is a type of polyester filament yarns produced by processing POY through a texturing process. This process disperses, curls and entangles the filaments composing the POY yarn, which gives DTY a fluffy appearance and gives it the properties of both natural fiber and synthetic fiber. DTY is typically used to produce fabrics and textiles for high-end apparel, high-end sportswear, high-end sports shoes, high-end sports bags, home furnishings and zipper tapes.
