In the current era of continuous innovation in shoe-making techniques, Fei-woven uppers have emerged as a standout due to their unique advantages, and nylon thermal fuse plays a crucial role in this process.

Nylon hot melt filament has many characteristics, which bring significant improvements to the flying fabric upper process. Its melting point is low, usually between 85℃ and 90℃. This characteristic enables it to melt rapidly when the melting point is reached in either dry or wet heat conditions, replacing chemical adhesives such as glue to closely bond other fibers together. Compared with traditional adhesives, nylon hot melt filament avoids volatile substances and dust pollution, is more environmentally friendly and non-toxic, and can also significantly save process flows and reduce downstream production costs.

In terms of strength and wear resistance, nylon thermal fuse performs exceptionally well. It has a high breaking strength. The breaking strength of long polyamide fibers used in textiles is 5.0-6.4g /d, and its wear resistance ranks among the top in all textile fibers. When applied to the flying fabric upper of shoes, it can greatly enhance the durability of the upper, effectively reduce wear and tear, and significantly extend the service life of the shoes.

Excellent dyeability is also a major highlight of nylon thermal fuse. Although polyamide fibers are slightly more difficult to dye than natural fibers, they are easier to dye than other synthetic fibers. Through acid dyes, a rich variety of colors can be produced, fully meeting different design requirements and providing a broad space for the appearance design of fly-woven shoe uppers.

In terms of elasticity and fit, nylon itself has good elasticity and flexibility. After being made into hot melt wire and used for fly-woven shoe uppers, the shoe uppers can stretch and contract freely with the movement of the feet, making them more comfortable to wear and closely adhering to the feet. They can also provide good support during sports. Moreover, the physical and chemical properties of nylon hot melt filament are stable, and it is less affected by external environmental factors. Under different temperature and humidity conditions, it can ensure that the quality and performance of the flying woven shoe upper remain consistent.

In the production process of flying woven shoe uppers, weft weaving and flying weaving are often used. However, although the shoe materials made by these methods have good lateral elasticity, their shape retention is relatively poor. The addition of nylon hot melt filament has effectively solved this problem. When combined with weaving, it can effectively enhance the skeletal support and stability of the shoe material, making the flying woven upper not only comfortable to wear but also maintaining a good shape.

Nylon hot melt wire, with its unique properties, has brought about multiple improvements in environmental protection, durability, aesthetics and comfort to the fei-woven upper process, promoting the continuous development and innovation of Fei-woven uppers in the shoe-making field.
