FDY polyester yarn fully drawn yarn introduces the stretching effect in the spinning process to obtain a wound yarn with high orientation and medium crystallinity, which is a fully drawn yarn.
DTY (Draw texturing yarn) is also called polyester low-stretch yarn. It is the finished yarn after continuous or simultaneous stretching and texturing on a machine. Both components are polyester, but the spinning process The different craftsmanship leads to different yarn effects.
Generally, FDY is mostly used for artificial silk and other fabrics, which feel smooth and soft. DTY low-stretch silk and DTY network silk are mostly used for sports fabrics.
If FDY polyester yarn introduces the stretching effect during the spinning process, a wound yarn with high orientation and medium crystallinity can be obtained, which is called FDY for short. In addition to the general properties of polyester drawn yarn, the tow has a network that produces periodic local entanglement points, which increases the cohesive force and improves the bundling. It is not easy to produce wool and breakage during weaving; Good performance, low shrinkage, high heat resistance and thermal stability, low thermal shrinkage, poor moisture absorption, poor electrical conductivity, and good physical properties. It can be directly used for weaving, mainly in the clothing and textile industries.
False twisted textured yarn is called DTY, also called stretch yarn. DTY network yarn: the network yarn refers to the filament in the network nozzle, the filaments are intertwined with each other through the action of the jet airflow to form periodic meridian points. Network processing is mostly used in the processing of POY, FDY polyester yarn and DTY. The low-elastic network yarn produced by the combination of network technology and DTY technology not only has the bulkiness and good elasticity of textured yarn, but also has many periodicity and network points, which improves The tightness of the filament eliminates several processes in the textile processing and improves the ability of the tow to pass through the water jet loom.
