ATY Polyester(AIR-TEXTURED YARN) air textured yarn: invented by the United States DuPont, the principle is to use jet method of air jet technology for the processing of the tow, forming irregular kinks, the tow has fluffy loop yarn . The key equipment is a jet deformable nozzle, when the filaments into the nozzle with low overfeed rate, hot air stream along the direction of operation of the tow to disperse the jet. The tow is fixed under deformation and heat setting in the nozzle. The nozzle design needs to reduce the gas consumption and improve the interlacing effect. The Y-shaped design can make the yarn knot stable with the same length between the knots. Jet deformable yarn is not a yarn with loose fiber tips, but purely mechanical production of irregular lap knots and kinked filaments, loop knot silk is the adjacent filament winding, heat treatment and the formation of the fixed.

Physical properties: air-textured yarn in bulk, air permeability, gloss, softness and other aspects of pre-deformation than the original silk. The fineness is 10-15% higher than the original, the boiling water shrinkage is maintained at about 3%, but the strength is reduced by 40% because only a small proportion of the monofilaments are stretched but they bear the full load of the tow.

DTY Polyester Yarn (Draw texturing yarn) Also known as polyester elastic yarn, is a continuous or at the same time on a machine tensile, deformation of the finished product after the wire. DTY network wire: Network wire is the network of nozzles in the nozzle, the role of jet stream, monofilament intertwined with each other at a periodic network of filaments. Network processing and more for the POY, FDY and DTY processing, network technology and DTY technology combined with the manufacture of low-elastic network of silk, both the deformation of silk fluffy and good flexibility, there are many periodic and network points to improve the filament The tightness, eliminating the need for a number of textile processing processes, and to improve the ability of the tow through the water jet loom.
