The micropores with special structures are distributed on the surface of the waterproof and breathable film in a high density, so that the waterproof and breathable film can not only block leakage of liquid water, but also allow gas molecules such as water vapor to pass through. The main application fields of the waterproof and breathable film at present comprise personal hygiene care products, medical protective products (such as medical mattresses, protective clothing, operating gowns, operating sheets, hot compress patches, medical pillowcases and the like), special places of personal protective products, clothing liners, auxiliary materials for medicine packaging, building industry and the like. The existing waterproof breathable film production equipment mainly comprises a casting machine, a preheating system, a stretching system, a cooling shaping system and the like, wherein the stretching system and the cooling shaping system are used for forming a micropore structure on a film through stretching and shaping the film through the cooling shaping system, but the existing stretching system and the cooling shaping system are used for carrying out heat transfer on the film in a manner of adopting hot oil flowing in a roller, so that the roller is heated unevenly easily, the stretching unevenly is caused, the air permeability deviation among different parts of a final film finished product is larger, and the waterproof breathable film production equipment is difficult to be applied to the field requiring smaller air permeability deviation.
Through searching, for example, chinese patent literature discloses a waterproof breathable film stretching device [ application number: CN201922336384.5; publication No.: CN211390126U ].
