An absorbent article, preferably a disposable absorbent article such as a diaper, is disclosed having an absorbent core which imparts increased wearing comfort to the article and makes it thin and dry. The absorbent core useful for an absorbent article comprises a substrate layer, a discontinuous layer of absorbent material, and a layer of thermoplastic material. A second surface of the discontinuous layer of absorbent material is in at least partial contact with a first surface of the substrate layer. Portions of a second surface of the layer of thermoplastic material are in direct contact with the first surface of the substrate layer and portions of said second surface of the layer of thermoplastic material are in direct contact with a first surface of the discontinuous layer of absorbent material. A process for providing a storage layer for an absorbent core useful in an absorbent article is further disclosed.

This invention is directed to a process for making solid, typically particulate, water-swellable material comprising coated water-swellable, preferably hydrogel-forming polymers, which are coated with a coating agent, which is such that it does not rupture when the polymers swell in a liquid, e.g., water or saline water. Hereto, the coating agent is extensible in wet state and comprises thereto a wet-extensible material that has a tensile stress at break in the wet state of at least 1 MPa. Typically, the coating agent comprises thereto an elastomeric polymeric material. The invention also relates to solid (particulate) water-swellable material obtainable by the process of the invention.

An absorbent article having a backsheet, an absorbent core, a topsheet, and a genital coversheet. The topsheet has an opening positioned to allow exuded fecal material to pass therethrough when the article is worn by a wearer. The genital coversheet is positioned across a portion of the aperture and covers the wearer's genitals. A void space is formed between the genital coversheet and the absorbent core and a void space is formed between the topsheet and the absorbent core.

Absorbent article with urine-permeable coversheet

The invention relates to an absorbent, disposable article, preferably a diaper, having a backsheet and a topsheet comprising a first waist region, a second waist region, and a crotch region interposed there between, a longitudinal axis, and an opening, which provides a passageway to a primary void space for receiving bodily exudates therein, positioned between the topsheet and the backsheet, whereby the opening is positioned in at least the crotch region along the longitudinal axis; whereby the topsheet is elasticated; and whereby the article has a shortened article portion, as defined herein, which has a shortened article length L, a stretched shortened article length Land a contracted shortened article length L, whereby the article and/or its topsheet has an specific elastic profile and/or a specific ratio of Lto L. The article preferably has a slit opening with on each side elastic regions, preferably in the shape of an X, as shown in FIG., and preferably making an angle with the adjacent topsheet and thereby bending away from the void space underneath the topsheet.

Articles with elasticated topsheets

This invention is directed to absorbent structures and preferred absorbent articles, comprising solid, typically particulate, water-swellable material that comprises coated water-swellable, preferably hydrogel-forming polymers, which are coated with a coating agent, which is such that it does not rupture when the polymers swell in a liquid, e.g., water or saline water. Hereto, the coating agent is extensible in wet state and comprises thereto a wet-extensible material that has a tensile stress at break in the wet state of at least 1 MPa. Typically, the coating agent comprises thereto an elastomeric polymeric material.

An apertured laminate web which may be used as a topsheet on a disposable absorbent article, such as a diaper. The laminate web is formed of a liquid pervious first material and a liquid pervious second material attached to the first material. The first material has an effective open area of at least about 10% and a plurality of apertures with an effective size of at least than 0.2 square millimeters. The second material has an effective open area of at least about 10% and a plurality of apertures with an effective size of at least 0.2 square millimeters. The apertures of the second material are aligned with the apertures of the first material. The second material preferably has a hydrophilicity which is greater than the hydrophilicity of the first material.

The invention relates to an absorbent, disposable article, preferably a diaper, having a backsheet and a topsheet comprising a first waist region, a second waist region, and a crotch region interposed there between, a longitudinal axis, and an opening, which provides a passageway to a primary void space for receiving bodily exudates therein, positioned between the topsheet and the backsheet; whereby the opening is positioned in at least the crotch region along the longitudinal axis; whereby the topsheet is elasticated; and whereby the article has a shortened article portion, as defined herein, which has a shortened article length L, a stretched shortened article length Land a contacted shortened article length L, whereby the article and/or its topsheet has an specific elastic profile and/or a specific ratio of Lto L.

The present invention relates to absorbent articles for retaining body fluids such as urine, menses, or fecal material. In particular, the absorbent article of the present invention comprises a liquid handling member that collapses at a pressure between 2756 Pascal (0.4 psi) and 3447 (0.5 psi) in order to reduce the likelihood of causing skin marking.

The present invention relates to a process for converting a continuous structure into discrete, spaced apart elements by means of an expandable support web. First, the continuous structure is combined with a support web comprising longitudinal expansion means. Then, after separation of the continuous structure into discrete elements, the discrete elements are spaced apart by expanding the support web. The process of the present invention is particularly well suited for the industrial manufacture of articles comprising fragile discrete elements supplied to the production process in continuous form.
