Polyester Drawn Textured Yarn (DTY)
Polyester Drawn Textured Yarn
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 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.
Tire cord Fabric
products
Superior product properties make the reinforcing material of choice for high-performance tires, hoses and composites.
Fabrics & Cords
Depending on the specifications of our customers the yarns are twisted, corded or processed into cord fabrics. The cord fabrics can also be dipped for excellent adhesion to rubber.
Sodium Sulfate
Sodium sulfate is a by-product of the production process and is used for detergent, glass, cement, coating, textile and chemical applications.
Applications
Tires & Runflat Tires
Due to the superior properties of fibers are used for high-performance tires and original equipment tires and constitute the only appropriate reinforcement for state-of-the-art runflat tire types.
Mechanical Rubber Goods
An excellent volume constancy is one of the major benefits of brake hoses reinforced with and in addition to its favorable mechanical properties, resistance to chemicals and its good processing features make it popular for the use in hose applications.
Composites
reinforced plastics stand out due to their excellent balance between stiffness and stability/resistance on the one hand and impact strength on the other. Learn more about this rather new field of application for here.
