Abstract
A moisture-permeable waterproof laminated fabric comprising a water-repellant base fabric and at least one porous film provided on one surface of the base fabric. The porous film is formed of a synthetic polymer composed chiefly of a polyamino acid urethane resin and has numerous fine pores provided by microcells which are continuous in the direction of its thickness. The laminated fabric has satisfactory waterproofness and moisture permeability as required for munition, survival and sport uses.
