Patent number: 6497893Abstract: The present invention relates to a topical delivery system effective in depositing a thin, tenacious and substantially continuous coating of a silk protein on skin by an aqueous emulsion mediated dissolution of protein from a substrate with subsequent transfer and deposition onto the skin. Coatings of silk protein on skin resist removal, thereby providing a protective barrier against chemically- and biochemically-induced skin damage. The treatment composition also provides a vehicle for administering an effective dose of an active agent to the skin surface.Type: GrantFiled: June 30, 1999Date of Patent: December 24, 2002Assignee: Kimberly-Clark Worldwide, Inc.Inventors: Dennis Stein Everhart, Robert Cosmo Di Luccio, Ali Yahiaoui, Wade Bolton May, David John Tyrrell, Elizabeth Deibler Gadsby, Gunilla Elsa Gillberg-LaForce

Patent number: 6479061Abstract: The present invention pertains to an airlaid composite which is made of pulp fibers, at least about 2% by weight bicomponent fiber, and moisture. This airlaid composite is unique in that a uniformly even composite is made which upon calendering, becomes a thin structure which maintains significant absorbency when saturated. The bicomponent fibers of the present invention include a first polymer component and a second polymer component, and the first polymer component melts at a temperature lower than the melting temperature of the second polymer component. Mixing of the pulp fibers with the bicomponent fibers is done in such a way that the fibers are evenly dispersed in the airlaid composite. This airlaid composite is then heated such that at least a portion of the first polymer component of the bicomponent fiber is melted, which bond the bicomponent fibers to many of the pulp and bicomponent fibers when cooled.Type: GrantFiled: October 26, 2001Date of Patent: November 12, 2002Assignee: Kimberly-Clark Worldwide, Inc.Inventors: Monica C. Fontenot, Terry Pearce Ford, James Jay Tanner, Jonathan Robert Owen, John Joseph Lassig, Barbara Jean Burns, Alan Grady Shuman, Victor Michael Gentile

Patent number: 6267252Abstract: The present invention pertains to a filter medium including an airlaid composite, which is made of pulp fibers, at least about 2% by weight bicomponent fiber, and moisture. This airlaid composite is unique in that, when used as a filter medium, it exhibits advantageous filtering properties as well as physical strength. The bicomponent fibers of the present invention include a first polymer component and a second polymer component, and the first polymer component melts at a temperature lower than the melting temperature of the second polymer component. Mixing of the pulp fibers with the bicomponent fibers is done in such a way that the fibers are evenly dispersed in the airlaid composite. This airlaid composite is then heated such that at least a portion of the first polymer component of the bicomponent fiber is melted, which bond the bicomponent fibers to many of the pulp and other bicomponent fibers when cooled.Type: GrantFiled: December 8, 1999Date of Patent: July 31, 2001Assignee: Kimberly-Clark Worldwide, Inc.Inventor: Nicole Michele Amsler

Patent number: 6190758Abstract: There is provided herein a multilayer laminate comprised of a layer of a film and a layer of a nonwoven fabric. The film is made from polymers and has as one surface a semi-crystalline/amorphous or “heterophasic” polymer, an optional inner, less expensive, filler type polymer, and as the other surface, a polymer with a lower coefficient of friction. The nonwoven fabric may be a spunbond or meltblown fabric, preferably spunbond and preferably also including a heterophasic polymer. The film and nonwoven components are bonded together using thermal point bonding preferably while the film is stretched at least 5 percent. Such a laminate may be made into a personal care product like a diaper, training pant, absorbent underpants, adult incontinence product, and feminine hygiene product.Type: GrantFiled: October 9, 1998Date of Patent: February 20, 2001Assignee: Kimberly-Clark Worldwide, Inc.Inventor: Steven Ray Stopper

Patent number: 5919177Abstract: There is provided a cushioned absorbent material which may be used as a bodyside liner for a personal care product which is made from a lofty nonwoven fabric onto which is extruded a film to form a laminate. The laminate is then apertured and has an 8 cc intake rate of at most 20 sec and a rewet of less than 1 gm. Such a liner may be used in personal care products like diapers, training pants, feminine hygiene products, absorbent underpants, adult incontinence products, and the like.Type: GrantFiled: March 28, 1997Date of Patent: July 6, 1999Assignee: Kimberly-Clark Worldwide, Inc.Inventors: William Anthony Georger, Mark Bruce Majors, Gregory Alan Zelazoski

Patent number: 5789523Abstract: Polyimide compositions can be substantially improved by incorporating in the composition an inorganic, low hardness, thermally stable, sheet silicate, such as muscovite mica, talc, and kaolinite, which results in improved wear resistance and reduced coefficient of friction.Type: GrantFiled: July 9, 1996Date of Patent: August 4, 1998Assignee: E. I. du Pont de Nemours and CompanyInventors: Daniel Eugene George, Joy Sawyer Bloom, Thomas Paul Feist

Patent number: 5700863Abstract: New polyimide polymeric blends which are environmentally friendly during compounding and give improved coefficient of friction in shaped articles prepared therefrom are provided by blending polyimides which are at least 90% imidized and substantially solvent free and have a mean particle size of about 30 .mu.m or less with at least one melt processible thermoplastic liquid crystalline polymer or polyamide and a lubricant.Type: GrantFiled: August 19, 1996Date of Patent: December 23, 1997Assignee: E. I. Du Pont de Nemours and CompanyInventor: Joy Sawyer Bloom
