  • Patent number: 8207071
    Abstract: The present invention teaches a vehicular upholstery PPT-fiber fabric that is formed from a double woven fabric in which a face weaving textile design has a number of intersections, called warp up intersections where a warp yarn passes over a weft yarn, and these are more than the number of intersections, called weft up intersection, where a weft yarn passes over a warp yarn. The warp yarn is formed by twisting an intermingled yarn composed of a PPT-multi-filament yarn and a high heat shrinkable PET-multifilament yarn whose shrinkage percentage in boiling water is more than 15%. An intermingle ratio of the PPT-multifilament yarn of the warp yarn is more than the intermingle ratio of the PET-multifilament yarn of the warp yarn. In the warp yarn, the PET-multifilament yarn is shrunk by heating, so that the substantial length of the PET-multifilament yarn becomes shorter than the substantial length of the PPT-multifilament yarn. The weft yarn is composed of PPT-multifilament yarn.

  • Patent number: 7892990
    Abstract: A press pad is provided for use in a laminate press. The pad includes a woven fabric of heat resistant strands wherein at least either the warp or the weft has a core made up of a plurality of strands within a sheath of an elastomeric material, and the other is made up of metal strands. Within the scale of the press pad, the strands making up the core lie substantially parallel to one another and to the longitudinal axis of the core. In use, therefore, when pressurized in the laminate press, the core structure collapses as the strands making up the core move relative to one another and the core tends to flatten out. This increases the springiness and compensation ability of the press pad without any loss of heat transfer ability.

  • Patent number: 7151062
    Abstract: A textile made at least in part with conductive yarns for the purpose of generating heat from an electrical power source. The textile has conducting yarns, or “heaters”, with conductivity and spacing tailored to the electrical source to be used and the heat to be generated. The heater yarns have a positive temperature coefficient whereby the resistance of the yarn increases with an increase in temperature and decreases with a decrease in temperature. “Leads”, such as conductive yarns, can be used to supply electricity to the heater yarns. A coating to the textile can electrically insulate the textile as well as provide protection to the textile during activities such as laundering or use.

  • Patent number: 6914020
    Abstract: A sound and heat insulation material for insulating buildings, motor vehicles, conduits, etc., is covered on at least one exterior surface with a material which reacts at a given temperature by foaming up, and which is difficult to ignite or inflammable. The exterior covering can be a sheet or fiber layer which is impregnated with the reactive material or coated with it. The fibers of the sound and heat insulation core layer can also be directly coated with the reactive material or be mingled with a variable proportion of foamable fibers. The sound and heat insulation element, which is difficult or impossible to ignite, has good insulating properties.

  • Patent number: 6851844
    Abstract: A fiber optic fabric includes woven optical fibers, an opaque coating on the fibers and openings on the high points of the weave. The opaque coating prevents light leakage from the fibers and the openings allow light to be emitted from the fabric in a directed manner. The fabric is capable of emitting light at an angle relative to the surface of the fabric such that the light is not visible from every viewpoint.

  • Publication number: 20040214495
    Abstract: Fabric and fabric like synthetic plastic or agricultural derived products and sheet products of diverse thickness (ranging from high thickness rigid products to flexible films) are made as multi-component systems (e.g. a core-sheath fiber) with a carrier portion adapted to a first function (e.g. a high strength core) and a secondary portion (e.g. the sheath) carrying anti-microbial particles in an effective amount of high accessibility. An alternative is a blend of response fibers (e.g. (1) anti-microbial particles in a first plastic fiber blended with a second natural fiber and coated for bonding, (2) blends of diverse plastic fibers. The products can be fabrics of indefinite length or form of coherent products.

  • Patent number: 6786243
    Abstract: An industrial fabric of the variety used in the papermaking and similar industries has machine-direction (MD) yarns and cross-machine-direction (CD) yarns, which may be interwoven with one another to form a woven structure. The industrial fabric includes, as at least some of the MD and/or CD yarns, sheath/core yarns which have a core yarn surrounded by a sheath. The core yarn and the sheath are visually distinguishable by the naked eye from one another, such as by color, so that wear on a surface of the industrial fabric can be monitored visually during its operating life by the visual change that would become apparent when the sheath is worn away from the core yarn.
