Hot melt, also known as low melting point fiber, is one of the fastest growing functional fibers in recent years. The products can be divided into two categories: polyester hot melt and nylon hot melt. By adjusting the raw material properties, the melting point can be controlled between 85 and 180 ° C. Hot melt and other fiber fabrics are made into fabrics, and then the fabrics are placed under high temperature and bonded together under dry heat or wet heat conditions. At present, hot melt is widely used in flying shoe uppers, curtain yarn, carbon fiber fabric surface shaping, chenille yarn, bondi yarn, high-end suit lining and other fields. It is a high-tech product with huge market prospects.
Fly-Woven upper is one of the important applications of hot melt. Since Nike revolutionized the launch of Nike Flyknit Racer using Flykint technology in 2012, well-known domestic and foreign manufacturers such as Adidas, Anta, and Li Ning have followed up, making Flyknit an important upper material in addition to cloth, leather and leather. Compared with traditional shoemaking processes, this product has the characteristics of low carbon and energy saving in terms of the use of raw materials, upper manufacturing, and molding. First, in terms of the use of raw materials, polyester and nylon fibers are more cost-effective than traditional leather, and the production process is simple, eliminating the tanning and finishing processes of leather, reducing waste and wastewater pollution; second, the shuttle and nylon fibers are combined together. The upper molding eliminates the cutting and sewing processes of traditional shoemaking and reduces the waste of the upper. Finally, during the setting process, due to the low melting point of the hot melt wire, the setting temperature is only about 180°C, which also saves electricity costs compared to traditional high temperature and high pressure setting. Therefore, the birth of the Fly-Woven upper is revolutionary and an important part of low-carbon life.
