    • 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.
    • 包括透液性顶层,吸收芯层和透气性外罩的吸收性物品在吸湿芯和外罩之间设置有透气性内层叠体。 透气性内层压板包括透气膜和非织造纤维网,并且比外盖更不透气。 低至中等透气性内层压板在物品被穿着时,在液体损坏之后,在高度透气的外罩的外表面上发生的感觉到的湿度,而不会严重阻碍水分从尿布流出。 保持穿着者皮肤附近水分离开物品的直接途径,并提高浓度梯度。 替代实施例包括有孔吸收芯,或不存在非织造纤维网,其中膜和吸收芯开孔在一起,或者位于顶层和吸收芯之间的浪涌层,其中浪涌层延伸以填充孔中的孔 吸收芯。
