Hot melt adhesive and PUR hot melt adhesive are the most commonly used adhesives in textile processing, especially for high imitation clothing. It is widely used for bonding non-woven fabrics, carpet seams, fabric linings, zippers, and more. The hot melt adhesive used in the textile industry must have good bonding strength, excellent flexibility, and wash/dry cleaning resistance.

In addition, due to the fact that most of the fabric undergoes steam treatment during the solidification process, the adhesive is required to have high-temperature steam resistance, a softening point higher than 115 ℃, and appropriate crystallinity. Improve the thermal stability of rubber. For example, when polyamide is used as a matrix, its lower limit content is 45% (mass fraction). For fiber fabrics with excellent flexibility, hot melt adhesives are required to have low processing viscosity.

What are the specific uses of hot melt adhesive machines in the textile industry?

1. PUR hot melt adhesive used for fabric bonding
The labor intensity of clothing can be greatly reduced through bonding and sewing, resulting in high-quality imitation clothing that fits well and is sturdy. The hot melt adhesives used for fabric bonding mainly include polyamide, polyphenols, and polyurethane.
2. PUR hot melt adhesive and ordinary hot melt adhesive used for lining processing
Adhesive lining is made by uniformly melting rubber on the surface of the fabric. In use, cut the adhesive lining into the desired shape and size, and apply PUR hot melt adhesive on one side to heat bond to the back of other fabric materials. It is arranged in the high imitation clothing layer as the skeleton of high imitation clothing, simplifying the processing and time of high imitation clothing, making it lightweight, beautiful, comfortable, shape preserving, washable, and durable. Interlining processing usually requires hot melt adhesive to be colorless, odorless, soft, fast, dry, and moisture resistant, and the adhesive should not affect the fabric and be light resistant.

Various hot melt adhesives can be used for lining processing. Almost all types of hot melt adhesives can be used. The most commonly used are ethylene vinyl acetate (EVA) hot melt adhesive, polyamide hot melt adhesive, and high-pressure polyethylene (HDPE) hot melt adhesive. The melt powder and the hot melt adhesive used for different applications and processing methods are also different.


3. Hot melt adhesive used for carpet bonding
The carpet used for hot melt adhesive is mainly a copolymer of ethylene and other vinyl monomers, such as ethylene vinyl acetate copolymer, ethylene acrylic ester copolymer, etc. In most cases, ethylene vinyl acetate copolymer (EVA) is used.
