The invention belongs to the field of mask base cloth, and discloses high-strength high-water-absorption high-air-permeability mask base cloth and a preparation method thereof. Bamboo and hemp fibersare subjected to cotton carding, lapping and spunlace to be prepared into double-layer non-woven fabric, nano bacterial cellulose is sprayed to the non-woven fabric through a spraying method, and thehigh-strength high-water-absorption non-woven fabric is prepared through drying and winding. The natural antibacterial activity of the bamboo and hemp fibers is well retained, and the strength, waterabsorbability and air permeability of the non-woven fabric are improved. The non-woven fabric prepared by the invention not only has good antibacterial activity, but also has high strength, high waterabsorption, good air permeability, very good market prospect and simple preparation process.
