Abstract
A topsheet for body fluids absorbent article having a plurality of liquid-pervious apertures, the topsheet including an upper fibrous layer having a relatively low density and a lower fibrous layer having a relatively high density. Around each of the apertures, the first and second fibrous layers are integrated together so that the topsheet has a density progressively increasing from an upper surface towards a lower surface of the topsheet and has, in the proximity of the lower surface, a density further higher than in the second fibrous layer. The topsheet thus formed improves so that an upper surface thereof can be maintained in a dry state during use of the article having the topsheet.
