  • Patent number: 6808790
    Abstract: Paper sheets useful for tissues, paper towels, napkins, disposable absorbent products and the like can be made to exhibit a high degree of wet resiliency. This property is achieved by using a combination of high yield pulp fibers (such as bleached chemithermomechanical pulp fibers) and a wet strength agent in an uncreped throughdrying process. The resulting product, when wetted, can spring back after being crumpled in one's hand.
    Type: Grant
    Filed: May 23, 2002
    Date of Patent: October 26, 2004
    Assignee: Kimberly-Clark Worldwide, Inc.
    Inventors: Fung-jou Chen, Mark Alan Burazin, Michael Alan Hermans, David Henry Hollenberg, Richard Joseph Kamps, Bernhardt Edward Kressner, Jeffrey Dean Lindsay

  • Patent number: 6273996
    Abstract: Low-density uncreped through-air-dried webs containing bleached chemithermomechanical pulp fibers and a wet-strength resin are calendered to significantly increase density and reduce caliper. When wetted, these webs substantially return to their original caliper and density and substantially regain their original fluid-handling characteristics. Consequently these webs are very thin when dry and thick when wet. They can be used for a wide variety of applications, including paper towels, wipers and fluid-handling components for infant care and personal care products.
    Type: Grant

    Assignee: Kimberly-Clark Worldwide, Inc.
    Inventors: David Henry Hollenberg, James Ellis Horton, Jr., Andrew Michael Lake
  • Patent number: 6221211
    Abstract: A multi-ply tissue contains an internal indicia, such as a printed pattern applied to the center ply, which is visible through the outer plies of the tissue and which indicates the presence of some unique ingredients within the tissue product.

  • Patent number: 5981645
    Abstract: A creping adhesive is described which provides the ability to readily control glass transition temperature (Tg) and adhesion and which can be easily removed from dryer surfaces. The creping adhesive contains a crosslinkable polymer and preferably an ionic crosslinking agent such as metal cations having a valence of three or more.

    Assignee: James River Corporation of Virginia
    Inventors: David Henry Hollenberg, Phuong Van Luu, Stephen Risley Collins
  • Patent number: 5795377
    Abstract: Papermaking sludge can be modified to a modeling clay-like consistency by the addition of one or more dispersing agents, such as polyacrylamide. The modified papermaking sludge can be formed into a number of useful products, such as paper sheets or extruded products.
