What is the difference between polyester high-elastic yarn and nylon high-elastic silk? The composition is different. One is nylon and the other is polyester. The price is different; the elasticity is different.
High-elastic yarn : English abbreviation FDY, which introduces stretching during the spinning process, can obtain a wound wire with high orientation and moderate crystallinity, which is a fully drawn yarn. Conventional stretched yarns of polyester and nylon are all chemical fiber filaments. The high-elastic silk fabric is smooth and soft, and is often used to weave silk fabrics. It has a wide range of uses in clothing and home textiles. Among them, in order to eliminate the gloss of the fiber, a section containing anatase type titanium oxide (T iO 2) is used to reduce the gloss of the fiber. If you want to get colored high-elastic yarn, you can add masterbatch during spinning or put the finished silk into the dyeing bucket for dyeing.
Low- elastic yarn: English abbreviation DTY, which is a finished yarn that is continuously or simultaneously stretched on a texturing machine and deformed by a twister. DTY network wire: Network wire refers to the filament in the network nozzle, which is acted upon by the jet stream, and the filaments are entangled with each other to form a periodic network point. Network processing is mostly used for the processing of POY, FDY and DTY. The low-elastic network wire manufactured by the combination of network technology and DTY technology has the fluffiness and good elasticity of the textured yarn, and has many periodicity and network points, which improves the filament. The tightness eliminates the need for several processes in textile processing and improves the ability of the tow to pass through the water jet loom.
The difference between high elastic wire and low elastic wire : low elastic wire is a finished wire which is continuously or simultaneously stretched and deformed on one machine. The 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 process. It can be used for low-speed spinning, high-speed stretch winding, and two processes in one spinning. Completed on the combined machine, the production line has low production cost, stable finished product quality, less broken yarn and good dyeing uniformity. The low elastic fiber is crimped and the high elastic fiber is straight.
