Patent number: 8766031Abstract: An absorbent article, preferably a disposable absorbent article such as a diaper, is disclosed that provides an improved immobilization of absorbent polymer material when the article is fully or partially urine loaded. This absorbent core is useful for providing an absorbent article of increased wearing comfort. Specifically disclosed is an absorbent core useful for an absorbent article comprising a substrate layer and absorbent material, the absorbent material comprising an absorbent polymer material, the absorbent material optionally comprising absorbent fibrous material, the absorbent fibrous material not representing more than 20% of the weight of absorbent polymer material, wherein the absorbent material is immobilized when wet such that the absorbent core achieves a wet immobilization of more than 50%, preferably of more than 60%, 70%, 80% or 90% according to the Wet Immobilization Test described herein.Type: GrantFiled: March 13, 2007Date of Patent: July 1, 2014Assignee: The Procter & Gamble CompanyInventors: Uwe Jurgen Becker, Ludwig Busam, Bruno Johannes Ehrnsperger, Torsten Lindner, Siegfried Link, Volker Maier, Sanaul Kabir Siddiquee, Gabriele Stiehl, Thomas Tombuelt

Publication number: 20140135726Abstract: 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.Type: ApplicationFiled: January 23, 2014Publication date: May 15, 2014Applicant: The Procter & Gamble CompanyInventors: Ludwig BUSAM, Uwe Jurgen Becker, Michael Divo, Bruno Johannes Ehrnsperger, Roland Engel, Torsten Lindner, Siegfried Link, Volker Maier, Sanaul Kabir Siddiquee, Gabriel Stiehl, Thomas Tombuelt-Meyer

Patent number: 8616867Abstract: A method and apparatus for forming a batt of particulate material which may be used in an absorbent article. The apparatus may include a vacuum zone, an air impermeable fence zone adjacent to the vacuum zone, and an air permeable fence zone adjacent to the vacuum zone. The air permeable fence zone may comprise an ambient air entry conduit in communication with an ambient air exit port. The method may include providing a laydown drum and a first web of material, positioning the first web of material substantially adjacent to the laydown drum, generating a vacuum through the laydown drum, depositing particulate matter onto the first web of material, and rotating the laydown drum.Type: GrantFiled: July 9, 2012Date of Patent: December 31, 2013Assignee: The Procter & Gamble CompanyInventors: Darrell Ian Brown, Bradley Edward Walsh, Joseph Allen Eckstein, Horst Blessing, Volker Maier, Siegfried Link
