Microporous films made of polytetrafluoroethylene resin are made of biaxial tensile method by using the pore forming properties of polytetrafluoroethylene resin. The membrane surface can reach about one billion per square centimeter of micropores, each pore diameter (0.1 m-0.5 m) than water molecule diameter (20 M-100 m) small hundreds of times, than water vapor molecules (0.0003 m-0.0004 m) in ten thousand times. The water vapor can pass, and not through the water, and the microporous structure can achieve excellent waterproof function; also because of the extremely small hole and vertical irregular bend, the wind can not through, which has the characteristics of wind and warmth. The composite and other fabrics, widely used in military medical clothing, clothing, leisure clothing, fire, gas, water operations and other special protective clothing, outdoor sports clothing, shoes, hats, gloves and other accessories, sleeping bags, tents, umbrellas and other materials.
