Patent number: 7300547Abstract: 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: November 6, 2003Date of Patent: November 27, 2007Assignee: Georgia-Pacific Consumer Products LLCInventors: Phuong V.

Patent number: 6596126Abstract: Modified polysaccharides (such as starches, gums, chitosans, celluloses, alginates, sugars, etc.), which are commonly used in the paper industry as strengthening agents, surface sizes, coating binders, emulsifiers and adhesives, can be combined into a single molecule with modified aliphatic hydrocarbons, which are commonly utilized, in conjunction with cationic moieties, as softeners, debonders, lubricants and sizing agents. The resulting molecule is a modified polysaccharide having an aliphatic moiety which can provide several potential benefits, depending on the specific combination employed, including: (a) strength aids that do not impart stiffness; (b) softeners that do not reduce strength; (c) wet strength with improved wet/dry strength ratio; (d) debonders with reduced linting and sloughing; (e) strength aids with controlled absorbency; and (f) surface sizing agents with improved tactile properties.Type: GrantFiled: January 20, 2000Date of Patent: July 22, 2003Assignee: Kimberly-Clark Worldwide, Inc.Inventors: Thomas Gerard Shannon, Daniel Arthur Clarahan, Mike Thomas Goulet, Wen Zyo Schroeder

Publication number: 20030131962Abstract: Textile materials, including paper webs, treated with a polyvinylamine polymer and a second agent that interacts with the polyvinylamine polymer is disclosed. The second agent added with the polyvinylamine polymer can be, for instance, a polymeric anionic reactive compound or a polymeric aldehyde-functional compound. When incorporated into a paper web, the combination of the polyvinylamine polymer and the second agent provide improved strength properties, such as wet strength properties. In an alternative embodiment, the polyvinylamine polymer and the second polymer can be applied to a textile material for increasing the affinity of the textile material for acid dyes.Type: ApplicationFiled: December 18, 2001Publication date: July 17, 2003Applicant: Kimberly-Clark Worldwide, Inc.Inventors: Jeff Lindsay, Tom G.

Patent number: 6582556Abstract: This invention pertains to security paper and methods of making such security paper. The invention comprises a light-colored base paper having a non-protection area of a first thickness, and a protection area of a second thickness on at least one major surface of the base paper wherein the first thickness is greater than the second thickness. The base paper comprises colorant whereby the protection area exhibits a translucence when viewed using transmitted light, and exhibits the colorant as a darker color indication, relative to the non-protection area, when viewed using reflected light. Transmission of light through a combination of paper fibers and the colorant of the invention, both being disposed at the protection area, is discernibly different from transmission of light through the non-protection areas of the base paper, when viewed with a human eye.Type: GrantFiled: March 14, 2002Date of Patent: June 24, 2003Assignee: Appleton Papers Inc.Inventors: Adam Vincent Missell, Joseph John Tremblay, Kathleen Elizabeth Wyles

Publication number: 20030106658Abstract: The invention relates to a process for producing a coated paper web. According to the process, a paper web is formed from a fibrous raw material in a paper machine, the paper web is coated with a pigment-containing coating mix, and the coated paper web is calendered. According to the invention, the paper web is coated with a coating composition that contains as the mineral pigment mainly a mixture of gypsum and calcium carbonate, the amount of gypsum being at minimum 10% by weight of the total amount of gypsum and calcium carbonate. With mixtures of calcium carbonate and gypsum, such as mixtures of PCC and gypsum and mixtures of PCC, ground carbonate and gypsum, there are obtained simultaneously a sufficient gloss and smoothness as well as a brightness and opacity better than with PCC-kaolin pastes.Type: ApplicationFiled: July 18, 2002Publication date: June 12, 2003Inventors: Teuvo Ilmonen, Soili Hietanen, Markku Leskela

Publication number: 20030085009Abstract: The present invention is a method for uniformly applying a foam to a wet tissue web is provided. Specifically, a foam is first formed from a liquid-based composition and a gas, such as air. Once formed, the foam is applied by a foam applicator to the wet tissue web. In one embodiment, for example, the foam applicator applies the foam with a flexible scraper contacting the wet tissue web during the application of the foam. When applied with the foam, the wet tissue web typically has a solids consistency less than about 95% by dry weight of the tissue web. In some embodiments, one or more vacuum slots may be utilized in conjunction with the foam applicator to facilitate uniform application of the foam to the wet tissue web.Type: ApplicationFiled: November 5, 2001Publication date: May 8, 2003Inventors: Joseph George Capizzi, Strong C.

Publication number: 20030056917Abstract: In the manufacture of tissue products from cellulose fibers, it is often desirable to enhance physical properties by the addition of chemical additives, including for example debonding agents. These additives serve to prevent or disrupt interfiber or intrafiber hydrogen bonding. Depending upon the nature of the chemical additive, debonding agents may also act as softening agents. During the papermaking process, chemical additives of this type can be added to fiber slurries in the wet end of a papermaking machine. Alternately, such additives may be sprayed upon tissue layers during manufacture, prior to assembly into multi-ply tissue structures. The chemical additives may include quaternary ammonium salts or organofunctional polysiloxanes. The chemical additives may include quaternary ammonium salts or organofunctional polysiloxanes or polysiloxanes. Some of the quaternary salts which may be used include salts comprised in part of imidazoline heterocyclic nitrogen ring structures.Type: ApplicationFiled: September 3, 2002Publication date: March 27, 2003Applicant: Kimberly-Clark Worldwide, Inc.Inventor: Graciela Jimenez
