▎ 摘　　要

NOVELTY - The fabric has a main body provided with a graphene polyurethane composite film layer (1) and a fabric layer (2). The fabric layer is formed by a warp and a weft weaving, where a thickness of the fabric layer is about 100 m-180 m. A density of the fabric layer is about 95g/m. The graphene-polyurethane composite film layer is uniformly coated on a surface of the fabric base layer, where the graphene polyurethane thickness of composite film layer is about 50 m-60 m. A weft yarn is made of nylon fiber, terylene (RTM: Synthetic polyester fiber) fiber silk thread and adhesive fiber ice wire strand. A twisting coefficient of the warp and weft is about 1000-1500. USE - Waterproof air permeable fabric. ADVANTAGE - The fabric increases micro Brownian motion active molecular distance, increases surface of the graphene of the microporous film hole polyurethane composite film layer, enhances permeability and ensures water drop does not pass through when reducing the temperature, reduces surface of the microporous film hole of a graphite alkene polyurethane composite film layer, improves heat preservation effect. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a waterproof air permeable fabric preparation method. DESCRIPTION OF DRAWING(S) - The drawing shows a perspective view of a waterproof air permeable fabric. ' Graphene polyurethane composite film layer (1) Fabric layer (2)
