[0002] In the textile industry, DTY generally refers to stretched textured yarn, also known as false-twist textured yarn or low-stretch yarn. This is a polyester filament obtained by stretching and false-twist-texturing POY. DTY is widely used in knitting or weaving various clothing fabrics. For example, fabrics made from polyester low-stretch yarn are characterized by their fluffy, soft, and elastic feel, and are widely used in textiles, clothing, and other industrial fields.
