PUR Hot Melt Adhesive for Bra Underwear Fabric to Foam Bonding 20kg
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.
Advantages
Excellent Bonding Strength
The adhesive provides strong and durable adhesion between fabric and foam substrates. After full curing, the bonded laminate maintains excellent integrity during garment manufacturing, daily wear, washing, and long-term use.
Fast Strength Development
Advanced fast-curing formulations can achieve rapid green strength after lamination, allowing laminated materials to be cut and processed within a short period of time. This helps manufacturers reduce production lead times and improve workflow efficiency.
Soft and Comfortable Hand Feel
Unlike traditional bonding methods that may create stiff laminate structures, PUR adhesive forms a flexible bond line that preserves the softness and elasticity of both fabric and foam. The finished garment remains comfortable against the skin and retains excellent wearability.
Superior Heat Resistance
The cured adhesive network exhibits outstanding thermal stability, helping prevent delamination and bond failure during heat-intensive manufacturing processes such as molding, pressing, and garment finishing.
High Washing Durability
The adhesive maintains bond performance after repeated laundering and exposure to moisture, perspiration, and daily wear conditions, ensuring long-term garment durability.

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: Does the adhesive affect the softness of the foam?
A: No. The adhesive is formulated to maintain the softness, resilience, and comfort of the foam. The laminated material remains flexible and comfortable for intimate apparel applications.
