When subjected to high heat or flame, the binder in the structure softens, releasing the restrained crimped fibers and any ridges and grooves and allowing the thickness of the fabric to increase.Type: GrantFiled: November 23, 2004Date of Patent: July 24, 2007Assignee: E.I. du Pont de Nemours and CompanyInventors: Laurence N. Bascom, Herman Hans Forsten

Patent number: 7247263Abstract: The invention is directed to a system which allows for the rapid application of a water immobilizing dispersion in sufficient quantities to increase the fire protective and wetting characteristics of water. This system also increases the evaporative cooling and quenching effects of water. The primary constituents of the composition of this system are water, purified Attapulgite clay, and an environmentally safe salt, e.g., magnesium sulfate.Type: GrantFiled: October 29, 2003Date of Patent: July 24, 2007Assignee: ITC Minerals & ChemicalsInventors: Dennis C. Parker, Anthony W. Carignano, David L. Ruff, Robert J. Purcell

Patent number: 7229938Abstract: A heat and fire resistant planar unitary shield formed of heat and flame resistant fibers and voluminous bulking fibers. The shield material has a heat and flame resistant zone with a majority of the heat and flame resistant fibers, and a voluminous bulking zone with a majority of the voluminous bulking fibers. The fibers are distributed through the shield material in an manner that the heat and flame resistant fibers collect closest to the outer surface of the shield with the heat and flame resistant zone, and the voluminous bulking fibers collect closest to the outer surface of the shield material with the voluminous bulking zone.Type: GrantFiled: May 6, 2005Date of Patent: June 12, 2007Assignee: Milliken & CompanyInventors: David E. Wenstrup, Gregory J. Thompson, Jason G. Chay, Ty G. Dawson

Patent number: 7229937Abstract: This invention relates to a thin reinforced nonwoven fabric for fire blocking an article, articles containing such fabrics, and methods for making the fabrics and fire blocking the articles. When exposed to heat or flame, the fabric is capable of increasing its thickness by at least three times. The fabric comprises an open mesh scrim having a having crimped, heat-resistant organic fibers compressed thereon and held in a compressed state by a thermoplastic binder. When subjected to high heat or flame, the binder in the structure softens and flows, releasing the restrained crimped fibers and allowing the thickness of the fabric to increase dramatically.Type: GrantFiled: March 23, 2004Date of Patent: June 12, 2007Assignee: E. I. du Pont de Nemours and CompanyInventors: Laurence Nelson Bascom, Warren F. Knoff

Patent number: 7225882Abstract: A barrier for retarding fire comprises water-permeable fabric for covering a substantial area, the fabric having at least 9 pockets per square foot, each pocket having a volumetric capacity of between about 0.03 cubic inches and about 17 cubic inches, wherein substantially all of the pockets contain between about 0.01 and about 2 grams of superabsorbent polymer per cubic inch of volumetric capacity of the pockets.Type: GrantFiled: January 14, 2004Date of Patent: June 5, 2007Inventors: John C. Miller, Deborah L. Miller

Patent number: 7226877Abstract: This invention relates to a thin reinforced nonwoven fabric comprising a liquid impervious polymeric layer, a compressed web of crimped fiber, a binder, and a reinforcing scrim. The fabric bulks when exposed to heat or flame and is useful as a component for fire blocking mattresses, upholstery, and the like.Type: GrantFiled: December 27, 2004Date of Patent: June 5, 2007Assignee: E. I. du Pont de Nemours and CompanyInventors: Laurence N. Bascom, Warren F. Knoff

Patent number: RE40314Abstract: A velour fabric article consists of a fabric body having a technical face formed by a filament stitch yarn and a technical back formed by a loop yarn. The filament stitch yarn includes a heat sensitive material, e.g. a hot melt material or a heat shrinkable material, and/or an elastomeric material, such as spandex. The loop yarn includes flame retardant material, such as M-Aramide fiber. The fabric body has a velour surface formed at one or both of the technical back and the technical face. Raised fibers of at least one of the technical face and the technical back may be entangled, including in and/or through interstices of the fabric body, toward the other of the technical face and the technical back, e.g., by a hydroentanglement process applied after finishing. The fabric body has permeability of about 90 ft3/ft2/min, or less, under a pressure difference of ½ inch of water across the fabric body.Type: GrantFiled: December 7, 2006Date of Patent: May 13, 2008Assignee: MMI-IPCO, LLCInventors: Moshe Rock, Edward P. Dionne, Charles Haryslak, William K. Lie, Douglas Lumb, Jane Hunter
