Abstract:

To develop a kind of waterproof and breathable heat retention laminated composite fabric, the waterproot and moisture permeable laminated composite fabrics were prepared from woven fabric, thermoplastic polyurethane (TPU) film, porous sponge, and polar fleece fabric as the basic materials, with moisture-curable polyurethane hot-melt adhesive by laminating 2 or 3 times. The micro-morphological structure of the laminated composite fabrics were observed and analyzed, and influencing factors on waterproof, moisture permeable, peel strong performance and warmth retention property were studied. It was obvious that the waterproof and moisture permeable and peeling strength laminated composite fabrics with porous sponge were slightly reduced but the warmth retention ratio was greatly increased by about 30% . And the solution to insufficiency of the heat retention property of the laminated composite fabric using in extremely cold environment region was basically solved.

Key words: porous sponge, thermoplastic polyurethane film, laminated composite fabric, heat retention property
