The first stratum serves as a liquid acquisition stratum that rapidly acquires and then transfers liquid to the second stratum. The second stratum serves to withdraw liquid from the first stratum and further serves as a temporary storage stratum. Methods for forming the unitary stratified composite are also disclosed.Type: GrantFiled: November 13, 2002Date of Patent: October 24, 2006Assignee: National Institute for Strategic Technology Acquisitions and CommercializationInventors: Peter A. Graef, Colin Elston, Daniel T. Bunker, Fred B. Howard, Jeffrey D. Mathews, Shahrokh A. Naieni, Charles E. Miller

Patent number: 6998017Abstract: An improved method for imprinting a paper web during a wet pressing event is disclosed which results in asymmetrical protrusions corresponding to the deflection conduits of a deflection member. In one embodiment, differential velocity transfer during a pressing event serves to improve the molding and imprinting of a web with a deflection member. Improved deflection members are also disclosed. Improved tissue webs produced are also disclosed having useful sets of physical and geometrical properties, such as a pattern densified network and a repeating pattern of protrusions having asymmetrical structures.Type: GrantFiled: May 9, 2003Date of Patent: February 14, 2006Assignee: Kimberly-Clark Worldwide, Inc.Inventors: Jeffrey Dean Lindsay, Mark Alan Burazin, Fung-jou Chen, Michael Alan Hermans, Philip Sim Lin, Kenneth Curtis Larson

Patent number: 6979386Abstract: A tissue product containing a cellulosic fibrous material and less than about 10 wt. % of a superabsorbent material (e.g., fibers, particles, etc.) is provided. In some instances, the superabsorbent material can absorb between about 100 to about 350 grams of an aqueous solution per gram of superabsorbent material. In some embodiments, the superabsorbent material can be applied at the stock-preparation stage of a papermaking process, and can be provided in a dry or preswollen state.Type: GrantFiled: August 22, 2000Date of Patent: December 27, 2005Assignee: Kimberly-Clark Worldwide, Inc.Inventors: Palani Raj R. Wallajapet, Dale A. Burghardt, Sheng-Hsin Hu

Patent number: 6964725Abstract: The present invention is a tissue product comprising at least one tissue sheet. Each tissue sheet comprises a first side and an opposing second side. At least one tissue sheet comprises selectively treated pulp fiber treated with at least one hydrophobic chemical additive distributed non-uniformly in the z-direction within the tissue sheet. The tissue sheet has a % z-directional hydrophobic chemical additive gradient between the first side of the tissue sheet and the second side of the tissue sheet of about 20% or greater.Type: GrantFiled: November 6, 2002Date of Patent: November 15, 2005Assignee: Kimberly-Clark Worldwide, Inc.Inventors: Thomas Gerard Shannon, James Daniel Lorenz, David Andrew Moline, Troy Michael Runge, Thomas Hampshire Schulz
