Drawn Textured Yarn (DTY) yarn is obtained when Polyester POY is simultaneously twisted & drawn. DTY yarn is mainly used in weaving & knitting of fabrics for making clothes, home furnishings, seat covers, bags and many other uses. DTY yarn can be in Semi Dull or Full Dull or Bright or Trilobal Bright depending upon the type of sections of filaments.
Technical Properties of DTY yarn can be moulded in several ways to make the yarn suitable for its vast uses. DTY yarn can be made with several combinations of Intermingle points – it can be Non-Intermingle (NIM) having 0 – 10 knots/meter or Semi-Intermingle (SIM) having 40 – 50 knots/meter or High-Intermingle (HIM) having 120 – 140 knots/meter. These knots are not actually the knots tied when two threads are broken but they are the tangle knots created by heating pressure. These Intermingle yarns, also known as interlaced yarn, are the replacement for lightly twisted yarns .Such twisted yarn can also be heat-set to make the yarn permanently thermo-set the twist. Catonic DTY is another variant of Polyester DTY that is mainly used in blankets. Catonic DTY is made from Catonic PET Chips.
