Patent number: 6051317Abstract: The invention relates to sheet-like absorbents for water and aqueous solutions, containing at a defined distributionA) at least one water-swellable synthetic and/or natural superabsorbent polymer, andB) at least one water-soluble synthetic and/or natural polymeras a matrix of sheet-like design wherein the superabsorbent component A) is integrated or fixed. The sheet-like absorbents have an increased absorptive capacity for water and aqueous liquids, particularly under load. They are manufactured by forming a sheet-like matrix from the water-soluble synthetic and/or natural polymers B) and providing same with said water-swellable synthetic and/or natural superabsorber A), e.g., by applying a solution of matrix B) on a surface, sprinkling same with component A), and drying the sheet-like structure thus obtained.Type: GrantFiled: August 20, 1997Date of Patent: April 18, 2000Assignee: Stockhausen GmbH & Co. KGInventors: Helmut Brueggemann, Kurt Dahmen, Dieter Lehwald, Roland Theilmann

Patent number: 5856245Abstract: A barrier web comprising a fabric that has been treated with a curable shear thinned thixotropic polymer composition, the fabric being adapted to be substantially impermeable to liquids, permeable to gases and impermeable to microorganisms. The barrier webs of the present invention are either impermeable to all microorganisms or are impermeable to microorganisms of certain sizes. The present invention also includes fabrics that are capable of either selectively binding certain microorganisms, particles or molecules depending upon what binding partners are incorporated into the polymer before application to the fabric.Type: GrantFiled: June 7, 1995Date of Patent: January 5, 1999Assignee: Nextec Applications, Inc.Inventors: J. Michael Caldwell, Peter Ellman

Patent number: 5853867Abstract: This invention concerns an absorbent composite a supporting member and a cationic absorbent polymer and anionic absorbent polymer particles fixed to the supporting member. This absorbent composite excels in absorbing capacity under pressure, vertical aspiration power, and flexibility and suffers only sparing exfoliation of an absorbent polymer. This invention further concerns an absorbent composite which contains an absorbent polymer in an amount of at least 30% by weight based on the total weight of the absorbent composite and, after absorbing a liquid, shows a value of not less than 3 for the expansion anisotropy specified by the following formula.Expansion anisotropy=(Ez/Ex+Ez/Ey)/2(wherein Ex, Ey, and Ez respectively represent coefficient of liner expansion in the directions of X axis, Y axis, and Z axis) and an absorbent article using the absorbent composite.Type: GrantFiled: September 13, 1996Date of Patent: December 29, 1998Assignee: Nippon Shokubai Co., Ltd.Inventors: Nobuyuki Harada, Yoshihiro Motono, Shigeru Sakamoto, Toshimasa Kitayama

Patent number: 5743895Abstract: The present invention is directed to an improved disposable diaper and method therefor. The disposable diaper achieves significant fluid absorbency through a wadding batt layer consisting solely of a combination of wood pulp and cotton pulp, rather than through a wadding batt layer comprising wood pulp and a superabsorbent polymer. In this fashion, the disposable diaper minimizes skin irritation that may be caused during rewetting when body waste fluids contacting the superabsorbent polymers carry a portion thereof back out through the diapers into contact with the skins of babies or children using the diapers. The disposable diaper also minimizes skin irritation caused when both the exterior portion of a diaper contacts a child's skin or the skin of a person touching the diaper, by the use of an outer and inner surface layer of a soft, cloth-like, non-woven bond material such as polyester.Type: GrantFiled: January 26, 1996Date of Patent: April 28, 1998Assignee: RMED International, Inc.Inventors: Edward Reiss, Brenda J.

Patent number: 5489469Abstract: A liquid-absorbent composite comprises (a) a water-absorbent polymer, (b) a water-insoluble inorganic material and (c) a water-insoluble hydrophilic fibrous material at a weight ratio between (a), (b) and (c) in the range of 100:5-1200:5-1200. It is very useful as the absorbent component for a sanitary napkin and a medical pad.Type: GrantFiled: May 28, 1993Date of Patent: February 6, 1996Assignee: Kao CorporationInventors: Takatoshi Kobayashi, Yukihiro Nakano, Zenbei Meiwa, Minoru Nakanishi, Tadashi Matsui
