Patent number: 12226296Abstract: Provided is a method for producing an absorbent article comprising a water-absorbing resin having an excellent initial water absorption speed under load even substantially without adding a liquid permeability enhancer. The method steps for producing the water-absorbing resin includes the step of polymerizing a monomer while adding certain polyalkylene glycol thereto so as to generate, during or after the polymerization, a crosslinked hydrogel polymer containing the polyalkylene glycol of a specific molecular weight, wherein the crosslinked hydrogel polymer has a centrifuge retention capacity within a given range and a final water-absorbing resin to be obtained has various physical properties (CRC, AAP, SFC, FSR) being within given ranges.Type: GrantFiled: March 18, 2022Date of Patent: February 18, 2025Assignee: The Procter & Gamble CompanyInventors: Carolin Michaela Borgmann, Heike Opper, Arsen Arsenov Simonyan, Yoshiro Mitsukami, Keisuke Kikuchi

Patent number: 8791320Abstract: This invention is directed to super-absorbent material, which comprises a super absorbent polymer core that is coated with an organic, polar coating agent, and whereby the particulate super-absorbent material has a contact angle and a corresponding cos CAm (as defined herein), whereby the cos CAm is more than 0.3, and whereby, when said coating agent is in the form of particles, said coating agent particles have a (weight) mean particle size of from 0.001 to 1 micron. The material is useful for absorbent structures and absorbent articles (comprising such structures). The coated super-absorbent material is typically present in said absorbent structure at least at a concentration of 50% by weight of the structure, preferably even 80% or even 90%. The invention also provides a process for making the absorbent material.Type: GrantFiled: November 8, 2007Date of Patent: July 29, 2014Assignee: The Procter & Gamble CompanyInventors: Bruno Johannes Ehrnsperger, Heike Opper, Udo Friedel Schoenborn

Patent number: 8414553Abstract: The present invention relates to a disposable absorbent article, such as a diaper, training pants, adult incontinence article, having a specific topsheet with an opening to receive bowel movement waste (BM) and which is such that it masks the waste present underneath said topsheet. The topsheet is air permeable and it has a uniform pore size distribution with small pores only and it has a low surface energy and therefore an alcohol repellency of at least 7, typically at least 9 or even preferably 10.Type: GrantFiled: August 10, 2010Date of Patent: April 9, 2013Assignee: The Procter & Gamble CompanyInventors: Anja Schuehle (Née Hoffmann), Joerg Mueller, Heike Opper, Georg Pescher, Mattias Schmidt

Patent number: 7597689Abstract: A disposable absorbent article with a backsheet and a first topsheet, is capable of being at least partially in contact with the wearer's skin when in use. The first topsheet being a fibrous three-dimensional web, having bonded regions where the fibers are bonded to another, and unbonded regions, where the fibers are unbonded to one another. The fibers extend from at least one unbonded region into at least two bonded regions, typically in the form of loops. The bonded regions form the support structure for the unbonded regions, and the surface area of the unbonded regions is at least 2 mm2. The topsheet has a thickness (caliper) of between 0.1 and 5 mm.Type: GrantFiled: November 7, 2003Date of Patent: October 6, 2009Assignee: The Procter & Gamble CompanyInventors: Anja Hoffmann, Joerg Mueller, Heike Opper, Georg Pescher, Mattias Schmidt
