The market for chemical fiber hot melt bonding materials is constantly evolving. Downstream industries such as footwear and apparel, home textiles, and industrial textiles have continuously raised their requirements for the stability and compatibility of hot melt raw materials. polyester thermal fuses, as the mainstream bonding raw materials, have different batch qualities, which directly affect the bonding effect of the finished products and the production yield. Coiling Group's high-tech chemical fibers focus on nylon hot melt filaments, polyester thermal fuses, TPU special fibers, and various hot melt net membranes. Based on industry practice, let's discuss the core points of polyester hot melt filament procurement.

When purchasing polyester hot melt filaments, prioritize selecting specifications based on your own process and end product positioning. Different melting points and fineness of polyester hot melt filaments have significantly different applicable scenarios. Key indicators such as melting point range, fineness, and oil content need to be paid attention to, matching the temperature of the hot press equipment and processing techniques. For applications in shoe materials, home textiles composites, and reinforcement of industrial fabrics, the toughness of the filament and the bonding performance after hot melting are all different. Do not simply refer to common market specifications; instead, combine your own hot press process conditions for sample verification to avoid problems such as adhesion failure or fabric surface defects when running the machine.

1. First, focus on the process: The melting point range is more crucial than the melting point number.

Hot melt filaments are not necessarily better with a lower melting point. The key is whether it can fit into your existing production line. The setting temperature, pressing time, running speed, and synchronization with the main fiber's thermal shrinkage will all affect the final bonding effect. A lower melting point may cause post-processing dyeing and finishing to melt prematurely; a higher melting point may lead to poor adhesion. It is recommended to provide the process parameters to the supplier and conduct sample verification by running the machine to compare, rather than just selecting based on the parameter table.

2. Then, consider the batch size: Sample qualification does not mean batch stability.

What truly affects costs is often batch consistency. Pay close attention to fluctuations in fineness and strength, the dispersion of thermal shrinkage rate, as well as roll forming and breakage conditions. Run a small batch trial production before placing an order, produce continuously at normal speed, and then measure peel strength and water washing resistance. Compared to unit price, rework rate, downtime, and customer complaints are the more costly aspects.
