    摘要: The present invention relates to breathable absorbent articles like baby diapers, adult incontinence articles and in particular to sanitary napkins or pantiliners. According to the present invention the articles are provided with an apertured backsheet for breathability. At least one of the breathable layers of the backsheet comprises a resilient, three dimensional web which consists of a liquid impervious polymeric film having apertures. The apertures form capillaries which are designed such that the backsheet provides an increased barrier to liquid passage out of the article and maintains water vapor permeability when the web is exposed to compressive pressure.

    摘要: The present invention relates to a composite laminated structure comprising a substrate and an apertured layer joined together by means of a layer of an adhesive composition. The laminated structure is made extensible in designated zones by mechanical straining and the adhesive composition provides both an effective connection of the layers forming the composite laminated structure and an improved processability of the laminated structure by mechanical straining. The composite laminated structure preferably constitutes side flaps in a disposable absorbent article such as a sanitary napkin.

    摘要: A disposable absorbent article which is substantially flat prior to use for wearing adjacent a body discharge area, having a body facing surface and a garment facing surface. The disposable absorbent article includes a liquid pervious topsheet, a backsheet, and an absorbent core intermediate the topsheet and backsheet. The absorbent core has a body facing surface and a garment facing surface, and has an expanding layer for expanding the article into a tridimensional structure while being worn by a user. The expanding layer includes a number of smaller expanding elements that are activated by body fluids, are decoupled from one another, and are capable of expanding substantially in only one direction upon activation by body fluids.

    摘要: A disposable absorbent article is provided which is substantially flat prior to use for wearing adjacent a body discharge area having a longitudinal centerline and a lateral centerline orthogonal thereto, and defining longitudinal and lateral directions respectively. The disposable absorbent article includes a liquid pervious top sheet, a back sheet joined to the top sheet, and an absorbent core intermediate the back sheet and the top sheet. The absorbent core includes an expanding member for expanding the article into a tridimensional structure while being worn by a user. The expanding member is activated by body fluids. The top sheet is capable of expanding as the absorbent article expands upon activation by body fluids.
