Lamination Machines for Membrane Bonding
topic
Lamination machines bond functional membranes including expanded PTFE, polyurethane microporous, and polyester-ether block copolymer membranes to face and backing textile layers using hot melt adhesive, polyurethane adhesive, or direct thermal bonding methods, with adhesive layer application, lamination nip temperature and pressure, and curing time controlling bond strength and the preservation of membrane breathability through the adhesive layer.
Role
Produces the waterproof breathable three-layer laminates used in premium outdoor performance clothing, protective workwear, and military fabrics by bonding the functional membrane between textile face and backer layers while maintaining the membrane's breathability and waterproof performance, with adhesive coverage percentage and continuity being the critical lamination parameter governing both bond strength and the proportion of membrane area that remains permeable to water vapour.
