There are many kinds of compound glues in the shoe material market, and the types and materials are also different. Traditional shoe material bonding generally uses water glue, which is complicated in process, high cost of shoemaking, poor air permeability, and poor shaping effect. In addition, shoes are prone to mold during long-distance transportation, especially when shipped by sea, causing huge losses to manufacturers. Therefore, hot-melt adhesive films are often used in the shoe material market for compounding, which can effectively solve this type of problem.
At present, there are many types of hot melt adhesive films in the shoe material market, such as PES hot melt adhesive omentum, TPU hot melt adhesive omentum, EVA hot melt adhesive omentum, PA hot melt adhesive omentum, PA hot melt adhesive film, and TPU hot melt adhesive film. Melt adhesive film, EVA hot melt adhesive film, etc. can be used for the compounding of shoe materials. Some are suitable for shoe upper compounding, some are suitable for insole compounding, and some are suitable for shoe sole compounding. Today, this article mainly talks about shoe upper bonding Applicable hot melt adhesive film, taking leather shoes and sports shoes as examples:
The upper composite of leather shoes and sports shoes is mainly based on TPU hot-melt adhesive membrane. This hot-melt adhesive membrane has high bonding strength and resistance to washing. The use of this kind of membrane to bond the upper has good air permeability and resistance. Mildew, non-loose surface, strong adhesiveness of the film, and no need to use needle and thread to reinforce, the adhesive place is soft, comfortable to wear, and the entire upper is more beautiful. Generally, when manufacturers choose hot-melt adhesive omentum composite, they pay attention to the problem of omentum weight. The weight directly affects the bonding degree of the upper. The higher the bonding strength, the heavier the omentum weight will be. If there are other special needs, such as waterproofing, then you can choose TPU hot melt adhesive film. TPU hot melt adhesive film has low composite temperature, good elasticity, and waterproof. It is quite suitable for composite shoe uppers.
