The present invention relates to disposable absorbent articles such as sanitary napkins, panty liners, baby diapers, adult incontinence articles and sweat pads. According to the present invention the absorbent article in the region designated for liquid deposition on its wearer facing surface has a single layer topsheet onto which liquid to be absorbed is provided during use of the article. The absorbent article includes a backsheet forming the liquid barrier surface and a unitary absorbent core between the topsheet and the backsheet. Importantly the unitary core provides improved liquid handling to the absorbent article and increases the masking, i.e. ability to hide stains due to absorbed liquid, of the article. This is particularly beneficial in the context of articles for absorption of liquids with high color intensity, such as menstrual liquid or urine of older adults.

Disposable absorbent article with unitary topsheet and unitary absorbent article

Absorbent members and methods of making the same are disclosed. In one embodiment, the absorbent member is a unitary absorbent fibrous web having a density profile through its thickness. In one embodiment, the density profile of the fibrous web is skewed toward one of the surfaces of the fibrous web. In such embodiments, the maximum density of the web may be located outside of the central 30% zone of the thickness of the web. In one embodiment, the method involves subjecting a precursor web to at least one cycle (or pass) through a mechanical deformation process. Typically, the method involves subjecting the precursor web to multiples cycles (or passes) through a mechanical deformation process.

Methods of making absorbent members having skewed density profile

Absorbent members and methods of making the same are disclosed. In one embodiment, the absorbent member is a unitary absorbent fibrous web having a density profile through its thickness. In such an embodiment, the density profile may be relatively centered through the thickness of the web and the maximum density of the web is located between about 35% and about 65% of the distance through the thickness of the web.

Multilayered unitary absorbent core

A composite web adapted for use as a component in a disposable absorbent article is disclosed. The composite web comprises a first fibrous layer and a second layer, the first and second layers each comprising a body-facing side and a garment-facing side and are disposed in a face to face relationship to form a laminate. The first fibrous layer comprises a fibrous web of randomly oriented fibers with respect to an X-Y plane, and a plurality of discrete regions of fiber reorientation at least on the body-facing side thereof, and a plurality of fibers having portions reoriented in a direction substantially orthogonal to the X-Y plane and extending toward the garment-facing side.

Inverse textured web

A substantially flat disposable absorbent article 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 a layer of compressed, cellulose based, linear fibers for expanding the article into a tridimensional structure while being worn by a user. The layer of compressed, cellulose based, linear fibers is activated by body fluids.

Disposable absorbent article comprising expandable fibers and being capable of self-shaping in use

A resilient, three dimensional, perforated plastic webs which allow passage of water vapor and preferably air, and are resistant to the transmission of aqueous fluids at least in one direction. According to the present invention the perforated plastic webs consist of a liquid impervious polymeric film having open and closed capillaries. More than half of the capillaries are closed and preferably shorter than the capillaries with aperatures, and provide the resilient three dimensional web with an increased resistance crush and to collapse the capillaries under compression. The resilient, three dimensional, perforated plastic webs can be used as one of the layers of a backsheet in an absorbent articles, such as, sanitary napkins, pantiliners. baby diapers, adult incontinence, and the like.

Resilient, three dimensional polymeric film comprising open and closed capillaries, and absorbent article with improved backsheet comprising the film

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.
