Double-layer mask material, double-layer mask and preparation method of double-layer mask

The invention discloses a double-layer mask material, a double-layer mask and a preparation method thereof.The double-layer mask material comprises a first film layer and a second film layer, a temperature sensing fiber layer is arranged between the first film layer and the second film layer, and the first film layer and the second film layer are attached together through the temperature sensing fiber layer; the two mask layers are bonded together through the temperature sensing fiber layer, physical compounding is adopted, the mask is safer than bonding, the selectable base cloth materials are wider and higher in quality, the mask cloth cannot be layered, and the water permeability and the air permeability of the mask base cloth are not affected. According to the preparation method of the double-layer mask material, the mask layers can be bonded through thermal compounding, a complex technological process is not needed, and the yield cannot be greatly influenced. The double-layer mask has higher liquid carry
