Embodiment Construction
[0016] See figure 1 The present invention relates to a waterproof and warmth-preserving layered composite fabric, which in turn includes an outer layer 1, a middle layer 2, and an inner layer 3. The outer layer 1 and the middle layer 2 are pressed together, and the outer layer 1 is a windproof, waterproof and breathable membrane, The layer 3 is a thermal insulation layer, and the inner layer 3 is attached to the middle layer 2.
[0017] The windproof, waterproof and breathable membrane is a microporous polyurethane membrane.
[0018] The microporous pore diameter of the microporous polyurethane membrane is 100-500 microns.
[0019] The outer layer 1 is also provided with a protective layer 4, and the protective layer 4 is a polyvinylidene fluoride sprayed film.
[0020] The middle layer is made of fabric, and the fabric includes an anti-wetting layer. The specific structure is: an anti-wetting layer and a napping layer are compounded on the upper and lower surfaces of the anti-wettin...
