Patent number: 11590035Abstract: An absorbent article including an absorbent core having a fluid distribution layer and fluid storage layer, the fluid distribution layer being formed of two or more sub-layers. A first sub-layer has a first amount of multiple component binder fibers or crosslinked cellulose fibers, or a combination thereof. A second and/or subsequent sub-layer comprises treated or untreated pulp and a second amount of multiple component binder fibers, crosslinked cellulose fibers, or a combination thereof. The % by weight of the first sub-layer of the first amount of multicomponent binder fibers and/or crosslinked cellulose fibers is greater than the % by weight of the second or subsequent sub-layer of the second amount of multiple component binder fibers and/or crosslinked cellulose fibers.Type: GrantFiled: May 15, 2019Date of Patent: February 28, 2023Assignee: The Procter & Gamble CompanyInventors: Cagda Biasutti, Carola Elke Beatrice Krippner, Michele Mazzeo, Henning Roettger, Reno Volkmer

Publication number: 20190350773Abstract: The present invention relates to absorbent hygiene articles, such as baby diapers, adult incontinence or feminine hygiene articles that incorporate an absorbent system. It is particularly suited for articles which are intended to receive more than one liquid gush load, as the absorbent system comprises an intermediate liquid storage member that holds the liquid of a gush and gradually releases it to an ultimate storage member exhibiting a smaller size than the intermediate storage member.Type: ApplicationFiled: May 15, 2019Publication date: November 21, 2019Inventors: Cagda Biasutti, Carola Elke Beatrice Krippner, Michele Mazzeo, Henning Roettger, Ralf Ehmke

Patent number: 10322039Abstract: The present invention relates to a layers layered absorbent element for use in a disposable absorbent article comprising a top layer and a bottom layer. The top layer is a fibrous nonwoven layer having a basis weight of from 20 to 100 gsm, a thickness from 0.25 to 5 mm, is formed with fibers having an average length from 26 to 200 mm and it has a fixed height saturation at 5 cm above 40%. The bottom layer is in direct contact with the top layer and comprises superabsorbent polymer (SAP) and cellulosic fibers. A plurality of fibers protruding from the bottom layer penetrate into the top layer.Type: GrantFiled: June 3, 2015Date of Patent: June 18, 2019Assignee: The Procter & Gamble CompanyInventors: Mariangela Caputi, Norbert Matthais Stelzer, Michele Mazzeo, Carola Elke Beatrice Krippner, Gerard A. Viens, Christopher Philip Bewick-Sonntag, Remo Bellucci

Patent number: 9439816Abstract: The present disclosure is directed to disposable absorbent articles comprising a structured fibrous web, the structured fibrous web comprising thermally stable, hydrophilic fibers that are thermally bonded together using heat producing a base substrate that is thermally stable. The base substrate is textured via mechanical treatment to increase its thickness and optionally modified via over bonding to improve its mechanical and fluid handling properties. The structured fibrous web provides optimal fluid wicking and fluid acquisition capabilities and is directed toward fluid management applications.Type: GrantFiled: May 6, 2014Date of Patent: September 13, 2016Assignee: The Procter & Gamble CompanyInventors: Eric Bryan Bond, Carola Elke Beatrice Krippner, John Brian Strube

Publication number: 20150342789Abstract: The present invention relates to a method for making a layered absorbent element, for use in disposable absorbent articles, which comprises a top layer and a bottom layer. The method includes providing a fibrous nonwoven layer having a basis weight from about 20 gsm to about 100 gsm, and a thickness of from about 0.25 mm to about 5 mm, providing an air laid or a wet laid manufacturing line comprising a forming screen, placing said nonwoven layer onto said forming screen, forming onto the nonwoven layer an air laid or wet laid layer comprising fibers and superabsorbent polymers by depositing these materials onto the nonwoven layer using an air laid or wet laid process where the nonwoven layer acts as forming screen. The resulting material is then compressed.Type: ApplicationFiled: June 3, 2015Publication date: December 3, 2015Inventors: Mariangela CAPUTI, Norbert Matthais STELZER, Michele MAZZEO, Carola Elke Beatrice KRIPPNER, Gerard A.
