Patent number: 9539344Abstract: The invention relates to creped prebiotic tissue products. The tissue products comprise prebiotics in sufficiently high amounts to have a prebiotic effect in use, without negatively affecting tissue product properties, such as tensile strength, stiffness or softness. Thus, in certain embodiments the present invention provides soft, durable creped prebiotic tissue products that are able to improve the growth of healthy bacteria such as Bifidobacterium spp. or Lactobacillus spp. without promoting growth of enteropathogenic bacteria. The tissue products provide these benefits yet have a GMT greater than about 500, a Stiffness Index less than about 20 and a TS7 value less than about 10.Type: GrantFiled: September 30, 2014Date of Patent: January 10, 2017Assignee: Kimberly-Clark Worldwide, Inc.Inventors: Michael Andrew Zawadzki, Jeffrey Janne Johnson, David William Koenig, Amy Lynn Vanden Heuvel, David Andrew Moline, Rebecca Ann Vongsa, Cathleen Mae Uttecht, Donald Eugene Waldroup

Patent number: 9410292Abstract: The disclosure provides a multilayered tissue web comprising treated cellulosic fibers selectively disposed in one or more layers, wherein the tissue layer comprising treated fibers is adjacent to a layer comprising untreated fiber and which is substantially free from untreated fiber. Generally the treated fibers have a rate of substitution of about 0.02 to 0.07. In this manner, the disclosure provides a multi-layered tissue web having treated fiber selectively incorporated therein, where the tissue web has basis weight greater than about 10 grams per square meter (gsm), such as from about 10 to about 50 gsm, a sheet bulk greater than about 8 cc/g, such as from about 8 to about 15 cc/g and Stiffness Index less than about 15, such as from about 8 to about 12.Type: GrantFiled: December 20, 2013Date of Patent: August 9, 2016Assignee: KIMBERLY-CLARK WORLDWIDE, INC.Inventors: Stephen Michael Lindsay, Michael Andrew Zawadzki, Jian Qin, Mike Thomas Goulet, Cathleen Mae Uttecht, Donald Eugene Waldroup, Deborah Joy Calewarts, Kenneth John Zwick

Publication number: 20150038934Abstract: A surge material for use in disposable absorbent personal care products includes a wearer-facing surface, a plurality of elongate grooves in the wearer-facing surface, and a plurality of apertures disposed in the grooves and extending through the surge material. The surge material can also have an average material plane and including a plurality of ridges extending in a z-direction from the average material plane, a plurality of grooves alternating with the plurality of ridges, wherein the grooves extend in the opposite z-direction from the average material plane, and a plurality of apertures through the surge material, wherein the apertures are disposed only in the grooves. The surge material can also include a hydrophobic treatment agent disposed on the ridges and a hydrophilic treatment agent disposed within the grooves.Type: ApplicationFiled: July 31, 2013Publication date: February 5, 2015Applicant: Kimberly-Clark Worldwide, Inc.Inventors: Virginia Lee Day, Frank Paul Abuto, Donald Eugene Waldroup

Publication number: 20140357743Abstract: A method is presented for forming a collapsed foam film-like structure, the method including positioning a composition applicator adjacent to a hot non-permeable dryer surface, producing a first frothed dispersion or frothed solution from a first dispersion or solution, applying the first frothed dispersion or frothed solution to the dryer surface, allowing the first frothed dispersion or frothed solution to convert to a collapsed foam film-like structure, and scraping the collapsed foam film-like structure from the dryer surface. The method can further include producing a second dispersion or solution, blending the first dispersion or solution and the second dispersion or solution, frothing the blended dispersion or solution, applying the blended frothed dispersion or frothed solution to the dryer surface, and allowing the frothed dispersion or frothed solution to convert to a collapsed foam film-like structure.Type: ApplicationFiled: May 30, 2013Publication date: December 4, 2014Applicant: Kimberly-Clark Worldwide, Inc.Inventors: Keyur Desai, Jian Qin, Jeffrey Frank Jurena, Frank Paul Abuto, Susan Elaine Shawver, Donald Eugene Waldroup, Deborah Joy Calewarts
