Zusammenfassung:The utility model relates to a high-air-permeability and liquid-impermeability sheet for a disposable absorption article. The fabric comprises at least one superfine fiber breathable waterproof net layer, through holes for communicating the surface layer and the bottom layer of the superfine fiber breathable waterproof net layer are formed in the superfine fiber breathable waterproof net layer; the size of the through holes is 0.5-10 [mu] m, and humidity discoloration coatings extending in the longitudinal length direction of the superfine fiber breathable waterproof net layer are arranged atintervals in the center of the surface layer of the superfine fiber breathable waterproof net layer in the transverse width direction. The high-breathability and liquid-impermeability sheet is of a two-layer structure or a three-layer structure. The high-breathability and liquid-impermeability sheet is formed by fixedly connecting the layers through the pricking points, meanwhile, the breathability of the high-breathabili
