High elastic yarn: FDY for short in English. Introducing stretching in the spinning process can obtain winding yarn with high degree of orientation and moderate crystallinity, which is fully drawn yarn. Conventional fully drawn yarns of polyester and nylon are all chemical fiber filaments. High elastic silk fabrics are smooth and soft to the touch and are often used for weaving artificial silk fabrics. Widely used in clothing and home textiles. Among them, in order to eliminate the luster of the fibers, a slice containing anatase titanium dioxide (TiO 2 ) was used to reduce the luster of the fibers. If you want to get colorful high elastic yarn, you can add masterbatch during spinning or put the finished yarn into the dyeing barrel for dyeing.
Low elastic yarn: DTY for short in English, is the finished yarn that is continuously or simultaneously stretched on a texturing machine and deformed by a twister. DTY network yarn: network yarn refers to the filament in which the filaments are entangled with each other and form periodic network points through the action of jet air flow in the network nozzle. Network processing is mostly used for the processing of POY, FDY and DTY. The low-elasticity 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 filament yarn. The tightness of the loom saves several steps in textile processing and improves the ability of the tow to pass through the water jet loom.
The difference between high-stretch yarn and low-stretch yarn: low-stretch yarn is the finished yarn after continuous or simultaneous stretching and deformation processing on one machine. High elastic yarn is fully drawn yarn, which has nothing to do with the production process. It is used as the code name of the one-step spinning and drawing process. Low-speed spinning and high-speed drawing can be used for winding. The two processes are spinning and drawing in one machine. Completed on the combined machine, this production line has low production cost, stable quality of finished products, less wool breakage, and good dyeing uniformity. Low elastic fibers are crimped and high elastic fibers are straight.
