Patent number: 7846296Abstract: An absorbent paper sheet is treated with an aqueous wax dispersion such that the sheet includes a fused wax and emulsifier residue in an amount of from about 1 to about 20 weight percent of the sheet based on the combined weight of the fiber, wax residue and an emulsifier residue in the sheet. The fused wax emulsion operates to make at least one surface of the sheet laterally hydrophobic, exhibiting a moisture penetration delay of at least about 2 seconds and less than about 40 seconds as well as a typical contact angle with water at one minute of at least about 50 degrees. There is thus provided absorbent products which exhibit both absorbency and resistance to moisture penetration. The treated sheet further exhibits microbial barrier properties, impeding transfer of bacteria, for example, through the sheet. There are produced tissue products which resist moisture penetration from propelled liquids as well as sequester sorbed liquids in the interior of the tissue.Type: GrantFiled: October 16, 2007Date of Patent: December 7, 2010Assignee: Georgia-Pacific Consumer Products LPInventors: Phuong V.

Patent number: 7419568Abstract: The present invention relates to cross-linked cellulosic fiber having improved absorbency characteristics when compared to conventional cross-linked fibers. The cross-linked cellulosic fiber is obtainable by reacting pulp in the sheet or fluff form with one or more reagents selected from organic molecule having acid and aldehyde functional groups “acid aldehydes.” The invention also relates to a method of producing the cross-linked fiber. The method includes heating the treated cellulosic fibers to promote intrafiber cross-linking. The cross-linked fibers are characterized by having an improved centrifuge retention capacity, fluid acquisition rate, resiliency, absorbent capacity, absorbency under load, and other absorbent properties. The inventive cross-linked fibers are useful in forming absorbent composites, and in particular absorbent cores for use in absorbent articles.Type: GrantFiled: June 21, 2005Date of Patent: September 2, 2008Assignee: Rayonier TRS Holdings Inc.Inventors: Othman A. Hamed, Harry J. Chmielewski, Dana B. McBee

Publication number: 20080128103Abstract: Method and arrangement for processing a paper or board web (1) or similar fibre web, in which method a processing mixture is spread onto the surface of the web. hi the method, the web (1) to be processed is lead from a press nip (8) and pressed between rolls (8) in this nip. Before the web enters the nip, such an amount of processing mixture is spread onto at least one side of the web (1), that the processing mixture is still wet when it enters the nip.Type: ApplicationFiled: December 1, 2005Publication date: June 5, 2008Inventors: Jussi Kangas, Vilho Nissinen, Petri Paiva, Petri Paloviita

Patent number: 7351308Abstract: A method is disclosed for application of compositions onto non-woven webs, such as paper webs. The present invention is also directed to products made from the process. In general, the method includes applying a composition to a non-woven web using a non-impact printer, such as an ink jet printer. The composition is applied, in one embodiment, as droplets that remain as discrete shapes on the substrate. In this manner, treated areas and untreated areas are formed on the web. Through this process, the water absorption and control properties of the web can be adjusted as desired while simultaneously treating the web with a composition that improves the physical and/or chemical properties of the web.Type: GrantFiled: March 3, 2006Date of Patent: April 1, 2008Assignee: Kimberly-Clark Worldwide, Inc.Inventors: John J. Urlaub, Thomas G. Shannon

Patent number: 7320742Abstract: A packaging device and method for absorbing and reducing moisture as well as a manufacturing process for such device. The packaging device is a container made from paperboard such as containerboards or linerboards with a corrugated medium. The paperboard is insulated with moisture absorbing additives comprising charcoal, activated charcoal, activated carbon, or substances mostly comprised of carbon. Perforations may be added in the boards to further permit moisture to reach the corrugated medium, permitting further absorption by the additives embedded within the corrugated medium in between the boards. This packaging device and method is favorable for storing or transporting objects which are sensitive to or would benefit from low moisture/humidity conditions.Type: GrantFiled: October 12, 2005Date of Patent: January 22, 2008Inventors: Kevin J. O'Neill, Albert J. Salese
