1. A manufacture method for polyurethane coated textiles using a reversible method, which comprises of application of a coat mixture including polyurethane, organic solvent, pigments and filling agents onto silicone or polypropylene paper, followed by drying, application of glue layer, gluing fabric or textile, drying again and then tearing the ready product off the paper, characterised in that the main component of the coat mixture is a solution in an organic solvent, preferably in dimethyl formamide, of linear or slightly branched polyurethane of molecular mass 30,000-60,000, preferably 35,000-45,000, modified with a linear or slightly branched plastomer such as polystyrene, vinyl chloride copolymer with vinyl acetate, vinyl polyacetate, methyl polymethacrylate, applied in an amount of up to 35 percent parts by weight in relation to polyurethane, preferably 10-20 percent parts by weight, if need be, with an addition of up to 5 percent, preferably 1-2 percent parts by weight, of silicone elastomer of molecular weight 300,000-500,000.
