Patent number: 6020275Abstract: Bonded composite open mesh structural textiles are formed of woven textile. The textile is formed from at least two, and preferably three, components. The first component, or load bearing member, is a high tenacity, high modulus, low elongation mono- or multifilament yarn. The second component is a polymer in yarn or other form which will encapsulate and bond yarns at the junctions to strengthen the junctions. The third component is an optional effect or bulking yarn. In the woven textile, a plurality of warp yarns are woven with a plurality of weft (fill) yarns. The weave preferably includes a half-cross or full-cross leno weave. At least a portion of the warp and weft yarns are first component load bearing yarns. The polymer component is used as required for the bonding properties necessary for the finished product, and especially to provide improved junction or joint strength.Type: GrantFiled: May 9, 1996Date of Patent: February 1, 2000Assignee: The Tensar CorporationInventors: Peter Edward Stevenson, Jeffrey W. Bruner

Patent number: 6007911Abstract: Industrial fabrics which contain thermoplastic weft or filling filaments characterized by having at least one segment of the filament's cross sectional area consisting of a foamed polymer are described. The unfoamed segment or segments of the filament contribute axial strength while the foamed segment or segments of the filament contribute to radial compressibility. Industrial fabrics utilizing these filaments have reduced permeability, reduced weft denier, and improved fabric rigidity.Type: GrantFiled: March 13, 1998Date of Patent: December 28, 1999Inventor: David Bowen, Jr.

Patent number: 6008146Abstract: An improved composite material of high temperature and chemical resistant material and polytetrafluoroethylene (PTFE) is provided. The composite material incorporates a coherent strand of commingled filaments of fiberglass and PTFE which is far more resistant to flex, abrasion, and chemical attack than conventional materials. Preferably filaments of expanded PTFE tow yarn and filaments of PTFE are combined through a process of air-jet texturing. Fabrics made from the composite fibers are combined with thermosetting phenolic or epoxy resins to produce pleated cartridge filter elements exhibiting superior performance in high temperature and corrosive environments.Type: GrantFiled: September 2, 1997Date of Patent: December 28, 1999Assignee: Gore Enterprise Holdings, Inc.Inventor: Stephen K. Stark

Patent number: 5985999Abstract: This invention concerns a composition comprising a blend of polyolefin with the reaction of a functionalized polyolefin and polyetheramine in which the polyetheramine is grafted into the functionalized polyolefin in a customary mixing apparatus. A process for producing the reaction product of functionalized polypropylene and polyetheramine by melting with polypropylene in a customary mixing apparatus is also disclosed. Blends of the present invention are advantageously useful to prepare paintable automotive body parts. This invention further includes dyeable polyolefin compositions containing the reaction product of functionalized polyolefin and polyetheramine. Dyeable polyolefin fibers, including polypropylene fibers, are disclosed, which may be made by melt spinning, and which may be employed to make woven and non-woven fabric.Type: GrantFiled: April 23, 1997Date of Patent: November 16, 1999Assignee: Huntsman, Petrochemical CorporationInventors: Richard Joseph Gilbert Dominguez, Christopher S. Henkee, Wheeler C. Crawford, Gerald W. Cummings, Kevin John Hess, Richard James Clark, Randall Keith Evans

Patent number: 5981408Abstract: A screen textile material for high precision and high density screen printing is made of a core and sheath type conjugate fiber in which a core component is formed of a thermotropic liquid crystalline polyester (A polymer) and a sheath component is formed by blending a flexible thermoplastic polymer (B polymer) and a thermotropic liquid crystalline polyester (C type) with a blending ratio of the C polymer of 0.15 to 0.45. The core and sheath type conjugate fiber has a specific color specification values to perform high quality printing by prevention of halation.Type: GrantFiled: July 10, 1998Date of Patent: November 9, 1999Assignees: Kuraray Co.,Ltd., NBC Industries Co., Ltd.Inventors: Junyo Nakagawa, Takashi Katayama, Toru Yokomizo, Hiroki Sano
