Abstract

See full text

An absorbent article including a liquid-permeable top layer, an absorbent core layer, and a breathable outer cover is provided with a breathable inner laminate between the absorbent core and the outer cover. The breathable inner laminate includes a breathable film and a nonwoven filament web, and is less breathable than the outer cover. The low to moderately breathable inner laminate substantially reduces perceived dampness occurring on the external surface of the highly breathable outer cover, following a liquid insult, when the article is being worn, without seriously hampering moisture flux out of the diaper. Direct pathways for moisture near the wearer's skin to exit the article are maintained, and a concentration gradient is enhanced. Alternate embodiments include an apertured absorbent core, or the absence of a nonwoven filament web wherein the film and the absorbent core are apertured together, or a surge layer positioned between the top layer and the absorbent core wherein the surge layer extends to fill apertures in the absorbent core.
