What is drawn textured yarn (DTY)?
DTY refers to Drawn Textured Yarn. Draw Textured Yarn are produced by simultaneously twisted and drawing polyester partially oriented yarns (POY) using high speed texturizing machines. These yarns are also called Air Textured Yarns (ATY) as the texturizing on the yarn is produced by using an air jet. It is a mechanical method. In the air-jet texturizing process a cold air-stream is used to produce bulked yarns of low extensibility.
This process of texturing can produce permanent distortions, crimps, loops, coils, or crinkles on the yarns without destroying the essential continuity of the filaments. This method not only improves the texture of the yarns but also gives yarns a soft and woolly feel. This process of texturing increases the warmth and comfort of the fabrics which are made using these types of yarns. This is mainly because the loops or crimps can entrap a multitude of small pockets of air which prevent the air movement through fibers and hence holds the fabric together.
Drawn textured yarns are mainly used in weaving & knitting of fabrics for making clothes, home furnishings, seat covers, bags, and many other uses. Depending on the type of section of filaments, DTY yarn can be in Semi Dull or Full Dull or Bright or Trilobal Bright.
