The difference between polyester high elastic yarn and nylon high elastic yarn
High elastic yarn: FDY in English, which introduces stretching during the spinning process to obtain winding yarn with high orientation and medium crystallinity, which is a fully drawn yarn. Conventional fully drawn yarns include polyester and nylon, both of which are chemical fiber filaments. High-elastic silk fabrics feel smooth and soft and are often used to weave silk-like fabrics. It has a wide range of uses in clothing and home textiles. In order to eliminate the luster of the fiber, slices containing anatase titanium dioxide (TiO2) are used to reduce the luster of the fiber. If you want to obtain colored high-elastic yarn, you can add color masterbatch during spinning or put the finished yarn into a dyeing bucket for dyeing.
Low stretch yarn: DTY in English, is a finished yarn that is continuously or simultaneously stretched on a texturing machine and deformed by a twister. DTY network yarn: Network yarn refers to filaments in which the single filaments are entangled with each other and form periodic network points under the action of jet airflow in the network nozzle. Network processing is mostly used for the processing of POY, FDY and DTY. The low-elastic network yarn produced by combining network technology and DTY technology not only has the fluffiness and good elasticity of deformed yarn, but also has many periodicity and network points, which improves the performance of filament yarns. The tightness eliminates several steps in textile processing and improves the ability of the tow to pass through the water-jet loom.
The difference between high-elastic yarn and low-elastic yarn: Low-elastic yarn is a finished yarn that is continuously or simultaneously stretched and deformed on a machine. High-elastic yarn is a fully drawn yarn, which has nothing to do with the production process. It is used as the code name for the one-step spinning and drawing process. It can use low-speed spinning, high-speed drawing and winding, and the two processes are performed in one spinning and drawing process. Completed on a combined machine, this production line has low production costs, stable quality of finished products, less wool breakage, and good dyeing uniformity. Low stretch fibers are curly and high stretch fibers are straight.
