What is DTY ?

Views:1031     Author:Site Editor     Publish Time: 2017-11-26      Origin:Site

Drawn Textured Yarn (DTY) 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 Bright or Trilobal Bright depanding 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. Different heating techniques can be used to make the yarn set for specific use - 1 Heater DTY is normally woolly & more stretchable as compared to DTY with 2 Heater. Also the 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 100 - 120 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. Polyester DTY yarn can also be twisted to high twists like 1500 TPM or 4000 TPM (twist per meter). 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.

 

Polyester DTY yarn can also be obtained in various colors by the dope dyed technology or by conventional dyeing. Dope dyed DTY is usually packed on paper bobbins whereas Raw White DTY that will be used for dyeing is loosely packed on perforated plastic tube so that all the yarn can be easily dyed when the bobbin is dipped in color. DTY is mainly produced in large quantity in China, India, Taiwan, Indonesia & Malaysia and is exported world-wide.
