Patent number: 7381664Abstract: Organic inherently conductive polymers, such as those based on polyaniline, polypyrrole and polythiophene, are formed in situ onto polymeric surfaces that are chemically activated to bond, ionically, the conductive polymers to the substrates. The polymeric substrate is preferably a preshaped or preformed thermoplastic film, fabric, tube, or a medical device for tissue repair regeneration and/or replacement, although other forms of thermoplastic and thermoset polymers can be used as the substrates for pretreatment using, most preferably, C-succinylation-based processes followed by exposure to an oxidatively polymerizable compound capable of forming an electrically conductive polymer. The resultant conductive surface imparts unique properties to the substrates and allows their use in antistatic clothing, surface conducting films for electronic components and the like, and electromagnetic interference shielding for civilian and military installations as well as implantable medical devices.Type: GrantFiled: March 17, 2006Date of Patent: June 3, 2008Assignee: Poly-Med Inc.Inventor: Shalaby W Shalaby

Patent number: 6602811Abstract: A composite textile fabric for removing moisture from the skin is provided. The composite fabric includes an inner, first fabric layer comprising either a polyester, polypropylene, acrylic or nylon yam material which is naturally, or has been rendered, hydrophilic and an outer, second fabric layer incorporating either a moisture-absorbent material such as cotton or a synthetic yarn which has been rendered hydrophilic, or a combination thereof. The first and second fabric layers are formed concurrently by knitting a plaited construction. The second fabric layer, but not the first layer, is blended with synthetic fibers treated to have antimicrobial properties or the second fabric layer is treated with an anti-microbial paste. An elastomeric yarn material may be added to both layers so that the composite fabric is stretchable.Type: GrantFiled: July 25, 2000Date of Patent: August 5, 2003Assignee: Malden Mills Industries, Inc.Inventors: Moshe Rock, Edward P.

Patent number: 6383960Abstract: 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: March 3, 2000Date of Patent: May 7, 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, Kuo-Shu Edward Chang

Patent number: 6180545Abstract: A reflecting warp-knit slide fastener tape is knitted with several kinds of knitting patterns. A marginal portion onto which fastener elements are attached extends along one longitudinal edge of the tape. The marginal portion is formed by tricot-stitch yarns, weft-inlaid yarns, and chain-stitch yarns which prevent the marginal portion from stretching. In the web portion, in addition to the tricot-stitch yarns and the weft-inlaid yarns one or more reflective members, which is in the form of a strip of retroreflective or light-reserve reflective film, are knitted in between wales contiguous to the marginal portion. The reflective members are sandwiched between the weft-inlaid and tricot-stitch yarns. The tricot-stitch yarns are transparent synthetic fiber yarns in order not to obstruct the reflecting feature of the reflective members.Type: GrantFiled: May 1, 1998Date of Patent: January 30, 2001Assignee: YKK CorporationInventors: Sadaji Okeya, Hideyuki Matsushima, Yoshio Matsuda

Patent number: 5981066Abstract: Applications of a metallized textile. The textile is activated by precipitating noble metal nucleation sites on the fibers of the textile. Immersing the activated textile in a suitably prepared solution of a metal cation, and adding a reducing agent, leads to the formation of a metal plating tightly and intimately bonded to the fibers of the textile. Exposure of the metallized textile to air oxidizes the surface of the metal plating. Applications of the metallized textile include acaricides, fungicides, bactericides, armor, electrodes, anti-static devices, RF shielding, and radar reflectors.Type: GrantFiled: August 9, 1996Date of Patent: November 9, 1999Assignee: MTC Ltd.Inventor: Jeffrey Gabbay
