POROUS FILM, MOISTURE-PERMEABLE WATERPROOF SHEET, COMPLEX, AND PROTECTIVE CLOTHING

摘要

The objective is to provide a porous film that is suitable as a base material for a protective clothing having excellent water pressure resistance and wearing comfort by reducing the internal heating of the worn clothing, as well as a moisture-permeable waterproof sheet and a protective clothing using the porous film. The objective is achieved with a porous film wherein the moisture permeability is 250 g/m2∙h or greater, the sum of the degrees of tensile elongation in the length direction and the width direction of the film is 100 to 500%, the water pressure resistance is 4,500 mm H2O or greater, and the ash content after incineration at a temperature of 850°C (JIS L 1013) is 0.5% by mass or less.
