<p>The present invention relates to a breathable waterproof film, and more specifically, to a high elastic breathable waterproof film manufactured by matching specific properties of a polyurethane film and a fiber, and to a manufacturing method thereof and a fabric for sportswear comprising the same. The purpose of the present invention is to provide a high elastic breathable waterproof film which maintains properties such as elasticity, moisture permeability, waterproofing property, etc, and naturally transfer-prints a pattern which can reduce air resistance, thereby being applied to ice skating outfits. To this end, as the high elastic breathable waterproof film with decreased surface friction drag, the present invention comprises the polyurethane film and the elastic fiber, wherein the tensile strength of the polyurethane film has 95 ~ 105% in comparison with the tensile strength of the elastic fiber.</p> |
