PA (Co-Polyamide) Hot Melt Adhesive Mesh Web
Breathable, Washable, Non-Elastic Net Bonding Interlining
Developed for invisible lamination, air circulation, and long-lasting washing resistance. The open mesh structure allows air and moisture vapor to penetrate freely, making it the ideal choice for sportswear, outdoor gear, and performance textiles.
Product Overview
PA co-polyamide hot melt adhesive mesh web is a breathable net-shaped thermoplastic bonding material. Different from solid hot melt films, its open mesh structure eliminates the rigid stiffening effect, keeping the original fabric soft while delivering superior wash and dry cleaning performance.
Core Advantages
Engineered to preserve fabric integrity while delivering uncompromising bond strength.
Excellent Air Permeability
Open mesh structure realizes free air and vapor circulation, eliminating uncomfortable plastic touch caused by solid adhesive layers.
Reliable Wash & Dry Clean
Endures over 15 industrial washing cycles and 10 dry cleaning runs without delamination or texture deterioration.
Non-Elastic & Soft Hand
No stretching or creeping deformation. Preserves original fabric softness, avoiding cardboard-like stiff feeling.
Invisible Lamination Effect
Low adhesive coating weight and transparent mesh ensure seamless bonding trace even on light-colored fabrics.
Wide Substrate Compatibility
Stably bonds fabric to fabric, fabric to leather and fabric to foam, without damaging inherent material properties.
Complete Model Specification
Standard configurations for various bonding requirements.
