Publication number: 20050065237Abstract: This invention is directed to a process for making surface treated absorbent gelling material by treating partially swollen absorbent gelling polymers, which have a specific water content with a treatment agent, such as a coating agent, and subsequently removing at least part of the water. The treatment agent thus typically forms a shell on the polymers or part thereof, which can extend when the polymers swell in water; thus, the treatment shell or coating does not rupture when the polymers swell in a liquid, e.g., water or saline water, the coating being extensible in wet state. The treatment agent comprises preferably an elastomeric polymeric material. The invention also relates to surface-treated absorbent gelling material obtainable by the process of the invention, and to products, e.g., disposable absorbent articles, comprising such material.Type: ApplicationFiled: August 5, 2004Publication date: March 24, 2005Inventors: Mattias Schmidt, Axel Meyer, Bruno Ehrnsperger, Stephen Goldman, Michael Divo, Edward Urankar

Publication number: 20050043474Abstract: 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.Type: ApplicationFiled: August 5, 2004Publication date: February 24, 2005Inventors: Mattias Schmidt, Axel Meyer, Renae Fossum, Bruno Ehrnsperger, Stephen Goldman, Michael Divo, Edward Urankar

Patent number: 6643994Abstract: 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.Type: GrantFiled: January 22, 2001Date of Patent: November 11, 2003Assignee: The Procter & Gamble CompanyInventors: Michael Divo, Ludwig Busam, Christofer Fuchs

Patent number: 6436508Abstract: The present invention relates to absorbent article such as sanitary napkins and panty liners comprising a topsheet, absorbent core, and backsheet which are breathable by the incorporation of a breathable backsheet and have a reduced tendency to exhibit garment wet through. The backsheet comprises at least one air permeable layer such as an apertured formed film or fibrous layer which is applied and preferably coated with a non-soluble, liquid swellabe material, such as polyvinyl alcohol. Upon contact with fluid discharge, the material swells and closes the apertures of the layer, thereby reducing air permeability and preventing the passage of liquid through the layer and thus through the backsheet onto the garment of the wearer of the article.Type: GrantFiled: April 19, 2000Date of Patent: August 20, 2002Assignee: The Procter & Gamble CompanyInventors: Fabio Ciammaichella, Michael Divo, Italo Corzani

Patent number: 6248202Abstract: A process for manufacturing individual layered structures and the structures themselves. A continuous layered structure is provided. The continuous layered structure has designated cutting regions and includes a particulate material between the layers. At least one of the layers is permeable to liquids. A thermoplastic material in liquid state is applied to the continuous layered structure over at least part of the designated cutting regions to provide the designated cutting regions with a joining means. The thermoplastic material is made of natural or synthetic polymers, or mixtures thereof. The thermoplastic material has a softening point, as measured according to the ASTM Method E 28-67, lower than 120° C.; a viscosity at 130° C. lower than 0.05 Pa.s; and a temperature range in which the viscosity changes between 0.05 Pa.s and 0.35 Pa.s which is greater than 5° C. The thermoplastic material is allowed to set.Type: GrantFiled: June 4, 1999Date of Patent: June 19, 2001Assignee: The Procter & Gamble CompanyInventors: Italo Corzani, Michael Divo
