Based on the pore forming characteristics of polytetrafluoroethylene plastic resin, the microporous film was made by biaxial tensile method. The surface of the membrane can reach more than one billion micropores per square centimeter. The diameter of each micropore (0.1 μ m-0.5 μ m) is hundreds of times smaller than that of water molecule (20 μ M-100 μ m) and tens of thousands of times larger than that of water vapor molecule (0.0003 μ m-0.0004 μ M); In addition, because the holes are extremely small and irregularly bent in the longitudinal direction, the wind can not pass through, so they have the characteristics of windproof and heat preservation.
