Interview: Li Binhong talk eddy current spinning core yarn development
October 31, 2018
Li Bin, director of National Textile Product Development Center, is a new type of yarn. In the world, only Texas Huayuan Eco-Technology Co., Ltd. can produce this unique yarn. Vortex spinning core yarn used in Japan's Murata eddy spinning equipment, because it compensates for the weak twist twist spinning, weak enough weakness, it is considered by some experts as "the perfect yarn." However, due to the market's lack of awareness of this yarn, the downstream product development lags behind, and the prospect of vortex spinning core-spun yarn is not optimistic. Recently, the reporter of China Textile Economy Information Network interviewed Director Li Binhong of China Textile Product Development Center on the eddy spinning core-spun yarn and asked her to talk about his own opinion on the development of eddy spinning core-spun yarn. CTEI: vortex spinning core yarn is what the characteristics of the main areas of application are those? Li Bin Hong: Eddy current spinning core yarn has its unique advantages. Jet vortex spinning is a kind of high-speed rotation of the compressed air stream to the skein twist yarn wrapped into yarn spinning method. Vortex spinning core-spun yarn is a kind of double structure yarn, which has two parts: core fiber and outsourced fiber. The core fibers are arranged in parallel and have no twist. The outsourced fiber is regularly spiral wrapped on the core fiber surface. Therefore, during the process of yarn spinning, the core yarn is at the center of the swirling flow of the vortex spinning core yarn and is gradually wrapped by the layer of the peripheral short fibers rotating with the gas flow, so as to prevent the worsted yarn In the inner and outer layers of fiber due to the force difference, there is the phenomenon of internal and external fiber transfer, and its special wrapping yarn structure and wrapped yarn structure, the eddy current spinning core wrapping effect is better. Polyester or other synthetic filament as the core, outsourcing of cotton fibers such as cotton fiber or regenerated cellulose fiber, both to improve the strength of the yarn, but also to ensure the yarn moisture absorption fast-drying, good breathability, made of fabric Organized, fluffy. And based on its special yarn structure, the finished product can have good homogeneity during dyeing. Since eddy spinning can process pure cotton yarn, and has the advantages of high spinning speed, so in the early 21st century has been rapid development. MVS yarn has the structure of ring yarn, with more features and popular features, yarn hairiness is less, reducing the phenomenon of pilling fabric, dyeing performance and wear resistance, the fabric has a smooth appearance, good hygroscopicity, quick-drying And other advantages. Vortex spinning core yarn products are mainly used for knitted sweatshirts, casual wear, home textile products, product applications are more extensive. CTEI: What kind of product do you think eddy spinning is best for? Li Binhong: MVS (Murata Vortex Spinner) (jet vortex spinning, the reporter note) is still a good type of chemical fiber cotton, especially cellulose fibers and blends. Such as Tencel, Modal, bamboo fiber and other new cellulose fiber jet vortex spinning machine production, can significantly improve the yarn quality and improve the style of the fabric. With wool, silk, linen, chemical fiber and other fiber blended yarn used as high-end knitted sweaters yarn, adding a low percentage of cashmere, can further improve the sweater feel and wearing comfort, improve product added value. CTEI: Do you have any suggestions on the application of vortex spinning core-spun yarn in the industrial chain? Bin Li: Any one product chain applications rely on the close cooperation between upstream and downstream. The development of new fibers has provided new opportunities for the development of vortex spinning technology and also provided more styles for new product innovation. To strengthen the cooperation between upstream and downstream to form integrated innovation is the only way for Chinese textile enterprises and will be more conducive to the popularization and application of new technologies. CTEI: Do you think the development prospects of domestic vortex spinning core yarn? Li Bin Hong: Now there are several spinning methods, different spinning methods to form a different yarn structure and yarn characteristics, each spinning method has its own characteristics, structure of the yarn have their own characteristics. To make a spinning method to be universal application, the key to see whether the development of distinctive, marketable products. The future of different spinning methods, according to the market demand for fabric style to decide, which depends on the different structural characteristics of yarn applications. The future of the spinning market will show the coexistence of a variety of spinning methods, the diversification of product structure, a variety of spinning methods will penetrate each other, complement each other, the characteristics of various yarns will be further integration and development, which also gives yarn Line product application development has brought tremendous room for development.
