▎ 摘　　要

NOVELTY - Producing a multilayer polyurethane membrane, comprises coupling a first support layer defined by a film of polyurethane and a second layer defined by a polyurethane film added with a determined quantity of graphene powder, a pigment and a solvent substance. USE - The process is useful for producing a multilayer polyurethane membrane which is useful in a multilayer fabric, preferably for the realization of articles of clothing of industrial work, and sports (claimed) e.g. technical-sport clothes, shoes and industrial work clothes. ADVANTAGE - The process produces the multilayer polyurethane membrane which provides the multilayer fabric with high impermeability and high windproof and thermal shock resistance capacities, and thus can be optimally used in clothing for use in industrial, technical and/or sport sectors. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for multilayer polyurethane membrane obtained by the above process.
