2026 Bra Cup Laminating Machine
2026-03-19
Bra cup (Underwear, intimate clothes) Laminating Machine is a multi-layer fabric/film/foam laminating equipment dedicated to bra cup/underwear production. The core is to firmly bond/laminate different substrates through specific processes, forming laminated/composite fabrics that are soft, breathable, waterproof, elastic, and warm.
Mainstream types and processes
1. PUR hot melt adhesive laminating machine (the most commonly used and high-end model):
Working principle: Moisture curing hot melt adhesive, solvent-free and environmentally friendly, irreversible strong adhesion, and water-resistant. Use PUR hot melt adhesive, heat and melt it, apply it, then press it with other materials, and cure it by absorbing moisture from the air;
Adhesive application method: dot coating/mesh transfer, suitable for fabric+TPU film, sponge+fabric, etc;
Core advantages:
- Environmental safety: solvent-free, no toxic emissions, in compliance with export standards.
- Durable and washable: Moisture reaction is irreversible, high adhesive strength, and washable.
- Soft to the touch: The amount of glue is controllable, and the finished product is breathable and elastic.
- Efficient and energy-saving: No need for solvent drying, relatively low energy consumption.
Main applications: Underwear fabrics, sponges, Lycra fabrics, as well as TPU/PE waterproof films, non-woven fabrics, etc.
Working principle: Using water-based or oil-based/solvent based adhesive, after scraping or spraying, drying in an oven or by drying roller and then laminating.
Core features:
- Low cost: Small initial investment in equipment and glue.
- Flexible adhesive types: Different adhesives can be selected according to needs.
- High energy consumption: Drying is required, resulting in relatively high energy consumption.
- Generally environmentally friendly: Oil based adhesives may have VOC emissions issues.
Main applications: mid to low end underwear, regular clothing, home textiles, etc.
- Working principle: relying on high temperature and high pressure+hot melt film/self resin composite.
- Core feature: Non adhesive composite: Pure physical process, extremely environmentally friendly.
- Main use: Suitable for seamless underwear and ultra-thin fabrics.
Core Structure and Process
- Structure: unwinding unit → gluing/heating unit → laminating pressing station → cooling and shaping → winding.
- Process: Base material unwinding and alignment → Glue coating/preheating → Pressing → Curing/cooling → Finished product rolling.
Application scenarios
- Bra: fabric+sponge+lining; seamless fabric+TPU film
- Thermal underwear: fabric+thermal cotton/film+lining
- Sports bra: elastic fabric+breathable film/antibacterial layer
Selection Recommendation
According to your actual needs, you can refer to the following selection directions:
• Pursuing high quality, environmental protection, and export
Preferred PUR hot melt Adhesive Laminating Machine. It has a good hand feel, is washable, and meets environmental standards, making it an ideal choice for producing mid to high end underwear and functional fabrics.
• Limited budget, focus on domestic sales, regular products
Consider a water-based/oil-based/solvent based adhesive laminating machine. Low equipment investment and mature technology can meet basic production needs.
• Production of seamless underwear and non-woven fabric products
A hot press laminating machine is a more suitable choice. It is efficient and environmentally friendly without glue.
Key technical parameters
When inspecting equipment, please pay attention to the following core parameters:
- Working width: commonly 1600-1900mm, determining the maximum width of the composite fabric.
- Production speed: Line speed range, such as 5-30 or 5-50 m/min.
- Total power: affects energy consumption, PUR models typically range from 50-60kW.
- Heating method: Thermal oil or electric heating, which affects temperature control accuracy and energy consumption.
- Control system: PLC+human-machine interface is mainstream and has a high degree of automation.
- Roll diameter: affects continuous production time.
