The invention discloses a method for making a novel mask, and preparation of a transparent sponge film material used for making the mask; the transparent sponge film is selected as a sponge with a transparency of more than 60%, and the transparent sponge film is divided into a multi-layer structure, an outer layer, an inner layer and several intermediate layers. Floor. The shape of the mask made by the present invention can be flat type, strap type, duckbill type, arch shape, etc.; breathing will become difficult as the fabric aperture becomes smaller and water absorption, and then the gas entry channel will gradually transfer from the center to the outside, when the whole is When there is difficulty, it will prompt you to change the mask; before using the outer layer, moisten it with 20-50% of the saturated water absorption, and use it after 1-5 minutes; when the user breathes, the water vapor in the exhalation will wet the glue It releases sodium chlorite and acid substances, and the two react to generate chlorine dioxide, sterilize and filter the air, have good sterilization and deodorization effects, and can prevent the excessive water vapor of ordinary masks and affect the disinfection effect.
