Zusammenfassung:The invention relates to a high-gas-permeability non-liquid-permeability sheet for disposable absorbing articles. The high-gas-permeability non-liquid-permeability sheet comprises at least one superfine fiber gas-permeability water-proof net layer, each superfine fiber gas-permeability water-proof net layer is provided with through holes communicated with the surface layer and the bottom layer ofthe superfine fiber gas-permeability water-proof net layer, each through hole is 0.5-10 micrometers in size, and the centers on the transverse width of the surface layers of the superfine fiber gas-permeability water-proof net layers are provided with humidity color-changing coatings which extend in the longitudinal length direction of the superfine fiber gas-permeability water-proof net layers atintervals. The high-gas-permeability non-liquid-permeability sheet is of a two-layer structure or a three-layer structure, and all the layers are formed by fixed connection of binding points; meanwhile, through the formation
