Application and application of TPU composite flame retardant fabric and composite flame retardant fabric

The microporous film was prepared by the method of biaxial stretching using the pore forming properties of PTFE plastic 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.
