Patent number: 6300259Abstract: A crosslinkable cellulosic fibrous product that includes cellulosic fibers and a crosslinking agent is disclosed. The crosslinkable cellulosic fibrous product can be formed as a web or sheet that has structural integrity and sheet strength sufficient to permit the fibrous web to be rolled, transported, and used in rolled form in subsequent processes. The crosslinkable fibrous product can be converted into a crosslinked fibrous product by subjecting the product to conditions sufficient to effect intrafiber crosslinking. Alternatively, the web can be fiberized and the resulting individual crosslinkable fibers combined with other fibers and/or other materials to provide a fibrous web containing crosslinkable cellulosic fibers. Subjecting such a web to crosslinking conditions provides a fibrous web that includes, in addition to other fibers or materials, crosslinked cellulosic fibers.Type: GrantFiled: April 26, 1999Date of Patent: October 9, 2001Assignee: Weyerhaeuser CompanyInventors: John A. Westland, Colin Elston

Publication number: 20010027072Abstract: The present invention is directed to a novel process of making N-isopropyl acrylamide (NiPAm) polymers based upon the reaction of poly(acrylic acid) and N-isopropylamine. The disclosed method of the present invention uses polyacrylic acid as a starting material to synthesize NiPAm polymers. In one embodiment, the present invention discloses a condensation reaction of an intermediate salt to form homopolymers, copolymers and terpolymers of N-isopropyl acrylamide (NiPAm) with acrylic acid and/or alkyl acrylates in a molten state, which is adaptable to a continuous reactive extrusion process. Binder compositions, water-dispersible products and thermoformable articles containing the NiPAm polymers are also disclosed.Type: ApplicationFiled: May 18, 2001Publication date: October 4, 2001Inventors: Pavneet Singh Mumick, Yihua Chang, James Hongxue Wang

Patent number: 6242073Abstract: An absorbent structure comprising freestanding osmotic absorbent sites disposed on or within a capillary substrate. The sites extend outwardly normal to the plane of the absorbent structure or fill apertures within the plane of the absorbent structure. Upon imbibing liquids, the sites of osmotic absorbent can expand without constraint from the substrate.Type: GrantFiled: May 24, 1995Date of Patent: June 5, 2001Assignee: The Procter & Gamble CompanyInventors: Dean Van Phan, Paul Arlen Forshey

Patent number: 6239050Abstract: A matrix for use in a method of photocatalytically decomposing organic compounds in a fluid includes a fiber glass mat substrate carrying a photocatalytic material. The fiber glass mat is made of randomly oriented glass fibers that have been substantially filamentized and needled whereby the filaments are interlocked. Adhesion of the photocatalytic material to the substrate is provided without requiring heat cleaning of the fiber glass by controlling the organic content of the fiber glass mat to be less than 1.0 percent by weight as measured by loss on ignition. This is achieved by using sizing compositions that preferably have little or no film forming polymer content.Type: GrantFiled: October 30, 1998Date of Patent: May 29, 2001Assignee: PPG Industries Ohio, Inc.Inventors: Kami Lammon-Hilinski, Anastasia Morfesis, Thomas P.

Patent number: 6239047Abstract: A wettable fiber or filament comprises a melt additive to a thermoplastic polyolefin such as polypropylene. The melt additive is a polyethylene oleiyl ether having the formula: R—O—{—CH2—CH2—O}x—CH2—CH2—O—H where x is an integer from 1-15, and R═CH3—(CH2)7—CH═CH—(CH)8— When the foregoing ether is added to a melt of polypropylene at levels of 2-15% by weight prior to the extrusion of the fibers or filaments, and the fibers or filaments are formed into fabrics, the fibers, filaments, or fabrics will exhibit permanent wettability, as well as excellent drape and softness. Such fabrics are useful, for example, as the skin contacting inner lining fabric of sanitary articles such as diapers, feminine hygiene products and the like.Type: GrantFiled: February 19, 1999Date of Patent: May 29, 2001Assignee: Polymer Group, Inc.Inventors: Valeria Griep Erdos, Carlos Viramontes, Rocio Guajardo
