Introduction
PUR Hot Melt Adhesive for Bra and Underwear Fabric-to-Foam Bonding. JCC-5023 is specifically designed for fabric-to-foam bonding applications in bras, underwear, and other intimate apparel products. It provides a reliable and durable bonding solution for laminating textile fabrics to various foam materials, enabling manufacturers to produce comfortable, seamless, and high-quality garments with improved production efficiency.
In modern intimate apparel manufacturing, fabric-to-foam lamination plays a critical role in creating molded bra cups, foam-lined underwear, seamless bras, sports bras, shapewear, and other functional garment components. The adhesive serves as the bonding layer between the outer fabric and foam core, ensuring excellent adhesion while maintaining the softness, elasticity, and comfort required for close-to-skin applications.
Manufacturing Process
A typical fabric-to-foam lamination process involves:
- Application of molten PUR hot melt adhesive onto the fabric or foam substrate.
- Lamination of fabric and foam under controlled temperature and pressure.
- Initial cooling to achieve immediate handling strength.
- Moisture-curing reaction that gradually forms a highly crosslinked polyurethane network.
- Subsequent cutting, molding, sewing, or assembly operations.
The fast-curing characteristics of the adhesive can support accelerated production schedules, including short waiting times before cutting and further processing.
Suitable Substrates
The adhesive is compatible with a wide range of materials commonly used in intimate apparel manufacturing, including:
Fabric Materials
- Nylon fabrics
- Polyester fabrics
- Spandex/Elastane fabrics
- Microfiber fabrics
- Lace fabrics
- Mesh fabrics
- Knitted fabrics
- Functional sportswear fabrics
Foam Materials
- Polyurethane (PU) foam
- Bra cup foam
- Molded foam cups
- Memory foam
- High-density foam
- Low-density foam
Packing and Storage
- Unopened, it can typically be stored in a cool, dry place at 15–30°C for 6–12 months.
- Once opened, use promptly and keep sealed or under nitrogen protection.
- Packaging: 20kg or 200kg for one barrel.
FAQ
Q: Can it replace TPU films or other membrane hot-press processes?
A: In most applications, PUR hot melt adhesive can replace TPU films or PA films used in hot-press bonding, offering lighter, softer, and washable bonds, while also reducing material costs.
Q: Does the adhesive provide good heat resistance?
A: Yes. After curing, the adhesive forms a crosslinked polyurethane network that offers excellent heat resistance, helping prevent delamination during molding, pressing, transportation, and storage.
Q: What's the Validity Period of PUR hot melt adhesive
A: 6 months.
