The bonding types of woven fabrics mainly refer to the combination of different woven fabric layers or other material layers through various processes to form composite fabrics with specific properties and appearance. This bonding technology can greatly broaden the application range of woven fabrics and improve their functionality and aesthetics. The following are some common types of woven fabric bonding:
1. Hot melt adhesive bonding
- Principle: Use the characteristics of hot melt adhesive melting at high temperature to bond two or more layers of woven fabrics together.
- Features: Fast bonding speed, high production efficiency, and high bonding strength.
- Application: Widely used in the production of composite fabrics in clothing, shoes, hats, luggage and other industries.
2. Polyurethane (PU) coating bonding
- Principle: Coat a layer of polyurethane material on the surface of woven fabrics, and make it tightly bonded to the fabric through drying, curing and other processes.
- Features: It has good waterproof, windproof, moisture permeability, and is wear-resistant and aging-resistant.
- Application: Suitable for outdoor clothing, sports equipment and other fields with high functional requirements.
3. Composite film lamination
- Principle: Compound one or more layers of polymer film (such as PTFE film, TPU film, etc.) with woven fabrics through a special process.
- Features: It can give the fabric multiple functions such as waterproof, breathable, and warm, and it is light, thin and soft.
- Application: Commonly used in the fabric production of outdoor clothing such as down jackets and jackets.
