Zusammenfassung:	PURPOSE:To produce a humidity permeable waterproof coating fabric excellent in humidity permeability and waterproof capacity. CONSTITUTION:A soln. of a synthetic polymer based on a polyurethane resin containing 1wt.% or more of an inorg. fine powder with an average particle size of 1mum or less and adsorption quantity of N,N-dimethylformamide of 200ml/100g or more is applied to a fabric twice by a wet coating method. By this constitution, a humidity permeable waterproof coating fabric having excellent humidity permeability and waterproof capacity and excellent in friction resistance and release resistance is obtained.
