Publication number: 20030139718Abstract: An absorbent composite having a reticulated core and a fibrous stratum is disclosed. The core and stratum are integrally formed, and the stratum is coextensive with a surface of the core. In one embodiment, the composite includes strata on opposing surfaces of the core. The core includes a fibrous matrix and absorbent material. The fibrous matrix defines voids and passages between the voids, which are distributed throughout the composite. Absorbent material is located within some of the voids. On wetting, absorbent material located in these voids is expandable into the void. Methods for forming the composite and absorbent articles that include the composite are also disclosed.Type: ApplicationFiled: November 13, 2002Publication date: July 24, 2003Applicant: Weyerhaeuser CompanyInventors: Peter A.

Publication number: 20030139717Abstract: An absorbent fibrous foam composite comprising a fluid intake capacity of at least 15 g/g, a vertical wicking distance of at least 10 cm, and an absorbency under zero load of at least 15 g/g. The absorbent fibrous foam composite comprising a water insoluble fibrous material and a superabsorbent material. The absorbent fibrous foam composite made by forming a slurry of water, a water-insoluble fiber, and a binding agent. A water-swellable, water-insoluble superabsorbent material is added to the slurry and the temperature is lowered until the water freezes. The frozen water is then removed by sublimation process and an absorbent fibrous foam recovered. The Gelation Time, which represents a fluid absorption rate of superabsorbent during the preparation, is critical to preparing uniform absorbent freeze-dried foams and can be adjusted by various mixing conditions and physical and chemical superabsorbent treatments.Type: ApplicationFiled: December 14, 2001Publication date: July 24, 2003Inventors: Jian Qin, Xiaomin Zhang, Sridhar Ranganathan, Yong Li

Patent number: 6533989Abstract: An apparatus and process for forming an absorbent web (26) includes an airlaying of a first fibrous stratum (28), and an airlaying of an intermediate fibrous stratum (40) onto the first fibrous stratum. A liquid, wet-strength agent is distributed onto fibers of the intermediate fibrous stratum, and at least a second fibrous stratum (28) is airlaid onto the intermediate fibrous stratum (40). The method is desirably configured to operatively form or join the intermediate fibrous stratum (40) with the first and second fibrous strata, and render the intermediate fibrous stratum (40) substantially non-dispersible in an aqueous liquid. In a particular aspect, the strata of the web (26) can be operatively compressed prior to curing the wet-strength agent. In another aspect, the liquid wet-strength agent can be distributed onto the fibers of the intermediate fibrous stratum (40) during an airlaying of the intermediate fibrous stratum.Type: GrantFiled: August 3, 2000Date of Patent: March 18, 2003Assignee: Kimberly-Clark Worldwide, Inc.Inventors: Anthony John Wisneski, Yong Li, Michael Franklin Kalmon

Patent number: 6524348Abstract: The invention is directed to a method of making carboxylated cellulose fibers whose fiber strength and degree of polymerization is not significantly sacrificed. The method involves the use of cyclic nitroxide free radical compounds as a primary oxidant and a hypohalite salt as a secondary oxidant in an aqueous environment. Preferably the oxidized cellulose is then stabilized against D.P. loss in alkaline environments and color reversion with a reducing agent such as sodium borohydride. Alternatively it may be treated with an oxidant such as sodium chlorite. The method results in a high percentage of carboxyl groups located at the fiber surface. The product is especially useful as a papermaking fiber where it contributes strength and has a higher attraction for cationic additives. The product is also useful as an additive to recycled fiber to increase strength. The method can be used to improve properties of either virgin or recycled fiber.Type: GrantFiled: August 17, 2000Date of Patent: February 25, 2003Assignee: Weyerhaeuser CompanyInventors: Richard A. Jewell, Joseph Lincoln Komen, Bing Su, S. Ananda Weerawarna, Yong Li

Patent number: 6437214Abstract: A distinctive absorbent article includes an absorbent core having multiple absorbent layers, wherein the absorbent layers interact in such a manner which preferentially locates absorbed liquid in an appointed, high saturation wicking layer. The localization of the liquid within this wicking layer increases the potential of this layer to move liquid through capillary action due to the higher saturation level and increased amount of liquid available. The intake capability of the absorbent system is maintained or improved over current systems by keeping a second layer of the absorbent system at low saturation levels through as many insults of the product as possible, while providing optimum intake performance through appropriate control of the composite properties.Type: GrantFiled: January 6, 2000Date of Patent: August 20, 2002Assignee: Kimberly-Clark Worldwide, Inc.Inventors: Rob David Everett, Thomas Gerald Bolwerk, Richard Norris Dodge, II, Violet May Grube, Yong Li, Debra Jean McDowall, Shannon Kathleen Melius, Lawrence Howell Sawyer, David Louis Zenker, Xiaomin Zhang, Sylvia Bandy Little, Billie Jean Matthews, Sridhar Ranganathan, Stanley Michael Gryskiewicz
