Patent number: 5891516Abstract: Fiber cement felts of the present invention include: a top fabric layer that includes fine machine direction yarns and fine cross machine direction yarns interwoven with the fine machine direction yarns; a bottom fabric layer underlying the top fabric layer that includes coarse machine direction yarns and coarse cross machine direction yarns interwoven with the coarse machine direction yarns; and a batt layer attached to and overlying the top fabric layer. Preferably, the top fabric layer is heat bonded to the bottom fabric layer. It is also preferred that the fiber cement felt of the present invention include a second batt layer that underlies the bottom fabric layer. In this multiple layer structure, the felt can have higher tenacity, improved resistance to blinding and compaction, and a reduced tendency to mark a fiber cement sheet during its formation.Type: GrantFiled: June 12, 1998Date of Patent: April 6, 1999Assignee: Weavexx CorporationInventors: Hippolit Gstrein, Oswald Breit

Patent number: 5863390Abstract: A paper making felt for use in hot press or press drying paper making processes comprising a base cloth layer and batt fiber layers, with at least the paper-contacting surface layer of the batt fiber layers composed principally of poly(paraphenylene benzoxazole) fiber. The felt exhibits a high degree of resistance to flattening, and consequently its effectiveness in removing water from the paper and its useful life for that purpose are enhanced.Type: GrantFiled: August 4, 1997Date of Patent: January 26, 1999Assignee: Ichikawa Co., Ltd.Inventor: Mitsuyoshi Matsuno

Patent number: 5770529Abstract: A liquid-distribution garment worn in body-side combination with substantially impermeable protective apparel. The garment is composed of at least one layer of a hydrophilically transmuted reinforcing fabric; and at least one layer of a hydrophilically transmuted absorbent nonwoven fabric joined to the layer of reinforcing fabric so that the joined layers have a water wicking rate of at least about 4 centimeters per 30 seconds in at least one direction. The garment may contain a body portion, sleeve portions and/or leg portions, at least one of those portions being formed from the material composed of at least one layer of a hydrophilically transmuted reinforcing fabric and at least one layer of a hydrophilically transmuted absorbent nonwoven fabric. The garment may have sub-portions that contain superabsorbents.Type: GrantFiled: April 28, 1995Date of Patent: June 23, 1998Assignee: Kimberly-Clark CorporationInventors: Kimberly Bradshaw Dennis, Ronald Francis Cook, Craig Farrell Thomaschefsky

Patent number: 5759662Abstract: A facing fabric (10) for a reusable incontinent product (40) having a pair of multi-filament ground yarn sets (14, 16) interknitted together with a warp knit third set of yarns (18) which define loops (22) on one face of the fabric (10) in a warp knit three bar construction. The loop-facing yarns (18) are unnapped, multi-filament polyester with a denier of about 150 to 300 denier in a range of about 1 to 5 denier per filament, and advantageously about 48 filaments when the denier is about 150 and about 132 filaments when the denier is about 300. A barrier layer (46) may be added to the fabric (10) to create the reusable incontinent product (40).Type: GrantFiled: December 19, 1996Date of Patent: June 2, 1998Assignee: Standard Textile Co., Inc.Inventor: Mark J. Heiman

Patent number: 5744222Abstract: The bedding of the present invention comprises a front cloth, a textural three-dimensional structure woven three-dimensionally, and a rear cloth. At least a portion of the fibers forming the front cloth the textural three-dimensional structure, and the rear cloth are electretic fibers containing microparticles of a substance having an electretic property, such as tourmaline. The front cloth, the textural three-dimensional structure, and the rear cloth are sewn together at their peripheral edges. The electretic fibers are affixed with ceramic microparticles of one or more types of ceramic such as cordierite, .beta.-spodumene, zirconia, zircon, magnesia and aluminum titanate.Type: GrantFiled: July 10, 1996Date of Patent: April 28, 1998Assignee: Life Energy Industry Inc.Inventor: Toshio Sugihara

Patent number: 5736473Abstract: Disclosed is a method of attaching a substantially uniform distribution of particulates to individual exposed surfaces of a matrix of fibrous material. The method includes the following steps: 1) electrically charging a matrix of fibrous material having individual exposed surfaces to create a substantially uniform distribution of charged sites at the exposed surfaces; 2) applying particulates to the charged matrix of fibrous material so that at least some particulates adhere at the charged sites; and 3) attaching particulates adhering to the fibrous material at charged sites by substantially non-transient bonding. Also disclosed is a fibrous composite structure composed of a matrix of fibrous material having individual exposed surfaces; and a relatively uniform distribution of particulate material attached to individual exposed surfaces of the fibrous material by substantially non-transient bonding.Type: GrantFiled: May 23, 1995Date of Patent: April 7, 1998Assignee: Kimberly-Clark Corp.Inventors: Bernard Cohen, Judith Katherine Faass, Lamar Heath Gipson, Lee Kirby Jameson

Patent number: 5691040Abstract: The laminate is formed of a sheet of a woven textile material derived from multifilamentary aramid, polyimide, polyamide, polybenzimidazole or cellulose fire retardant yarns and a sheet of non-woven textile material. The adhesive used to produce the laminate should prevent slippage of the two materials relative to one another and fraying of the woven textile material while enabling the laminate to be air permeable, and having a minimum ten (10) cubic feet per minute (CFM) when tested in accordance with test method ASTM D737. This product is cheaper to manufacture and is more comfortable than the known quilted and coated material.Type: GrantFiled: December 18, 1995Date of Patent: November 25, 1997Assignee: Marcanada Inc.Inventors: Claude Barbeau, Ross Cochran

Patent number: 5645926Abstract: A flexible fire and heat resistant material comprising an intimate mixture of organic intumescent filler and organic fibres adapted to char intensely within the temperature range of 200.degree. C. to 500.degree. C. The added presence of inorganic fibre components enhances the structural integrity of this structure both during char formation up to 500.degree. C. and at higher temperatures up to 1200.degree. C. once char oxidation takes place.Type: GrantFiled: February 3, 1995Date of Patent: July 8, 1997Assignee: British Technology Group LimitedInventors: Arthur Richard Horrocks, Subhash Chander Anand, Barry Jakeman Hill

Patent number: 5624738Abstract: The outer shell consists of a plain weave multifilament fabric derived from aramid, polyimide, polyamide or polybenzimidazole yarns. The inner sheet is a woven, non-woven or knitted material. The two sheets are laminated with an adhesive which enables the two sheets to be laminated in such a manner that the two sheets are non slipping with respect to one another while enabling the laminate to be air permeable with a minimum of ten (10) cubic feet per minute (CFM), when tested in accordance with ASTM D737.Type: GrantFiled: December 18, 1995Date of Patent: April 29, 1997Assignee: Marcanada Inc.Inventors: Claude Barbeau, Ross Cochran
