During the spinning process of chemical fibers, each filament is a multifilament composed of multiple very thin single filaments. If compressed air is used to loosen the filaments during the spinning process, and they rotate and twist each other into a network shape, it is called network filament.
Network DTY wire
DTY wire is processed by network nozzles under the action of compressed air. It has a good effect in improving the aurora effect and waxy (resin) feel of DTY silk, and brings some unique style to DTY silk.
According to the current market situation, according to the different network degree and network fastness, there are weak network yarn, light network yarn, medium network yarn and heavy network yarn. Under normal circumstances, network yarns of various properties are produced by corresponding types of network nozzles to achieve the best results, that is, light network yarns are produced by light network nozzles, and heavy network yarns are produced by heavy network nozzles.
Light mesh, heavy mesh
The production of DTY medium-heavy mesh and light mesh refers to the number of networks (unit: number of networks/meter). DTY yarns will obtain network points after slight and short pulling. The number of webs is generally controlled by adjusting the air pressure. Of course, it is also related to the speed of the texturing machine and the draft ratio before and after the web nozzle. Too many webs (excessive webbing) may cause web spots on the surface of the fabric (due to web spots). Strong, the twist cannot be fully untwisted during the relaxing process, and the dye uptake rate is different during dyeing). Too few network numbers (excessive light mesh) will cause network points to loosen and fluff under tension during weaving or weaving preparation (the purpose of the network is to avoid hairiness and enhance yarn strength).
Textured yarn
Using the characteristics of synthetic fibers that are plasticized and deformed by heat, they are made under the action of machinery and heat. Straightened fibers turn into crimped fibers, which are called deformed fibers, also known as deformed filaments. Yarn composed of deformed fibers has bulk and elasticity and is called deformed yarn. Textured yarns are divided into two categories: one is mainly bulky, called bulked yarn, which is characterized by a bulky appearance and uses acrylic as the main raw material. It is mainly used for knitted outerwear, underwear, fleece and blankets. The other type is mainly elastic, called elastic yarn, and its characteristic is that the yarn can rebound quickly after being stretched. Stretch yarn is divided into two types: high elasticity and low elasticity. High-elastic yarns are mainly nylon, used for elastic shirts, pants, elastic socks, etc.; low-elastic yarns include polyester, polypropylene, nylon, etc. </p
