Patent number: 7419570Abstract: The present invention discloses a process and a method providing a high bulk tissue which is both strong and soft. Specifically, it has been discovered that certain low pressure printing technologies may be used to deliver a bonding material to the surface of a high bulk paper web such as an uncreped, through-dried web. The bonding material may be applied to the web either before, during or after the web is softened with a mechanical straining process which will decrease the web bulk by no more than 20% of the initial bulk in order to increase the web softness. The web may be softened by any of a variety of mechanical straining processes such as, for instance, microcreping, microstraining, rush transfer, or other low-compressive softening methods. The cured bonding material on the web may not only increase the bulk of the web when dry and wet, but also increase the wet resiliency and the wet strength of the web.Type: GrantFiled: November 27, 2002Date of Patent: September 2, 2008Assignee: Kimberly-Clark Worldwide, Inc.Inventors: Fung-Jou Chen, Jeffrey D.

In an alternative embodiment of the method, the suspension has a pH value of under 4 at the time of addition of the aluminum containing component and a phosphorus containing component.Type: GrantFiled: February 23, 2007Date of Patent: October 30, 2007Assignee: Kronos International, Inc.Inventors: Lydia Drews Nicolai, Siegfried Blümel

Publication number: 20070218796Abstract: A paper composite for use on billboards, including at least one water-resistant paper outer layer impregnated with a polymeric resin, and having one or more pigmented or clear coatings suitable for high quality printing on the surface of the paper, the composite optionally also including a reinforcing lightweight polymeric fabric. A method of applying a visible textual or pictorial image to a billboard includes attaching a composite of this invention, with an image on it, to the billboard. A method of forming a composite of this invention includes adhering together a polymeric fabric and a paper sheet and, either before or after the adhering step, impregnating the paper sheet with a first synthetic polymeric resin in an amount sufficient to render the sheet water-resistant and thereafter applying a coating layer on the paper sheet.Type: ApplicationFiled: March 16, 2007Publication date: September 20, 2007Inventor: Peter C.

Patent number: 7270876Abstract: A unique primer emulsion chemistry yields excellent adhesion of polyethylene terephthalate (PET)resin to clay coated paperboard (with high starch content)at reduced coatweights of the primer emulsion and the resin as compared to other primer and tie-resin chemistries currently employed for moisture barrier applications. A primer used for adhesion enhancement is an ammonium catalyzed, self-crosslinking copolymer of ethylene-vinyl acetate with N-methylol acryl amide functional groups attached to a polymer backbone. Use of the primer in amounts up to about 0.5 pounds per ream permits PET coatweights of as low as 10–12 lbs per ream and lower for some applications.Type: GrantFiled: November 26, 2003Date of Patent: September 18, 2007Assignee: International Paper CompanyInventors: Ladislav Bednarik, Vivek Rohatgi, David V.

Patent number: 7247391Abstract: The present invention concerns a method of producing a calendered, coated fibrous web, according to which method a fibrous web is coated with a coating colour containing a coating pigment, and the coated fibrous web is calendered. According to the invention, at least 1%, preferably 10 to 100% of the weight of the pigment comprises calcium oxalate, and calendering the coated web by online calendering. The properties of the calcium oxalate pigment are so advantageous for calendering that it is possible to obtain a reasonably high gloss already with a machine calender (online calendering), which will eliminate need for a separate offline calender in the production line of matt surface papers.Type: GrantFiled: June 25, 2002Date of Patent: July 24, 2007Assignee: M-real OyjInventors: Kirsi Nissinen, Petri Silenius

Patent number: 7241508Abstract: An improved pigment-coated paper is provided which enables the use of a non-acidic basesheet in the manufacture of a fragrance release paper. The non-acidic basesheet, compared to the conventionally used acidic basesheet, is brighter and less brittle, and therefore imparts improved visual effects and reduces the likelihood of cracking. The clay-based coating composition is mildly alkaline when wet (pH between 7.5 and 8.5) and upon drying on the basesheet, becomes mildly acidic (pH between 6.0 and 7.0). A method of making the improved pigment-coated paper using a non-acidic basesheet in the manufacture of a fragrance release paper is provided, comprising the steps of preparing the basesheet, applying the premixed pigment coating composition using rollers and blade leveling devices, and drying the pigment coating composition. A fragrance sample construction, for use in magazines, catalogs, leaflets, etc.Type: GrantFiled: October 12, 2005Date of Patent: July 10, 2007Assignee: West Linn Paper CompanyInventors: Christopher James Corrigan, David Randolph Goss
