  • Patent number: 6746978
    Abstract: Heat bonded thermoplastic and partially thermoplastic nonwoven webs which have been thermomechanically treated while under low strain rate tension show significant improvement to their coformability and softness. More importantly the low strain rate thermomechanical treatment imparts a high degree of commercially valuable elasticity. The resultant webs find use in all nonwoven applications where softness, conformability and elasticity are useful. The resultant webs develop elasticity in only one direction but the two embodiments provide the ability to create elasticity in the machine or cross machine direction of a roll of precursor material. In addition virtually any precursor web containing at least 70% thermally bonded thermoplastic fibers can be used.

  • Patent number: 6746760
    Abstract: The gas adsorption sheet of the present invention has a granular activated carbon-containing sheet comprising a granular activated carbon having an average particle diameter of 60 to 600 &mgr;m, a supporting fiber for fixing the granular activated carbon in contact with it, and an adhesive fiber which mainly contributes to shape retention. An air-purifying filter of the present invention is obtained by forming the gas adsorption sheet into a shape of pleats or wave. A method for producing a gas adsorption sheet of the present invention comprises a step of forming a granular activated carbon-containing sheet by using an aqueous slurry containing a granular activated carbon, a supporting fiber and a water-swelling adhesive fiber.

  • Patent number: 6743742
    Abstract: A composite sheet has a layer of reinforcing fiber impregnated with a thermoplastic resin. Non-woven fiber is partially impregnated with the thermoplastic resin to provide a bondable surface that can be subsequently bonded to other materials, such as plastics, foam and metal. Such an apparatus may be formed by heating and compressing the thermal plastic resin against the reinforcing fibers of the base layer and against the non-woven fibers, such that the base layer may be fully impregnated while the non-woven fibers may be partially impregnated. A thermal plastic resin must have a melting point less than either the reinforcing fibers of the base layer, or the non-woven fibers.

  • Patent number: 6734125
    Abstract: A woven textile fabric is disclosed which is formed of synthetic yarns of at least two different deniers to which a solid polymeric film is laminated. An adhesive polymeric coating is provided for adhering the solid polymeric film to the woven textile fabric. The combination of yarns of different deniers provides a superior adhesion surface for the polymeric film. The yarns and the polymeric coating are preselected respectively in deniers and thicknesses so as to render the fabric substantially impermeable to fluid under pressure, while maintaining superb packageability and anti-blocking properties for use in vehicle occupant restraint systems. An air bag incorporating the woven textile fabric of the invention and having two outer surfaces and pre-configured air holding cavities woven therein to which a solid polymeric film is bonded for receiving and containing fluid under pressure for use in a vehicle air restraint system is also disclosed.

  • Patent number: 6713412
    Abstract: Specific fabric articles exhibiting very low air and/or gas permeability (even upon application of high inflation pressures) and very high tear strengths are herein disclosed and claimed. Such a specific fabric also permits the incorporation of discrete openings (through cutting, for example) through which air and/or gas introduced by an airbag inflation canister will travel. Such a specific fabric acts as a barrier to the complete introduction of high pressure inflation gases into an airbag cushion, thereby permitting a more controlled, safer inflation upon the occurrence of a collision event. Thus, the specific inventive fabric permits movement of inflation gas and/or air substantially solely through the openings within the fabric and not through the interstices between the individual fiber constituents.

  • Patent number: 6701971
    Abstract: Coated inflatable fabrics, more particularly airbags to which very low add-on amounts of coating have been applied, are provided which exhibit extremely low air permeabilities. The inventive fabrics are primarily for use in automotive restraint cushions which require low permeability characteristics (such as side curtain airbags). Traditionally, heavy, and thus expensive, coatings of compounds such as neoprene, silicones and the like, have been utilized to provide such required low permeability. The inventive fabric utilizes an inexpensive, very thin coating to provide such necessary low permeability levels. Thus, the inventive coated airbag possesses a coating of at most 3.0 ounces per square yard, most preferably about 0.8 ounces per square yard, and exhibits a leak-down time (a measurement of the time required for the entire amount of gas introduced within the airbag at peak pressure during inflation to escape the airbag at 10 psi) of at least 7 seconds.

  • Patent number: RE38422
    Abstract: This invention relates to a cushioned floor covering article wherein the mat includes a tufted carpet placed on the top side of a foam rubber sheet and at least one foam rubber protrusion integrated within at least a portion of the bottom side of the foam rubber sheet. Such an article provides effective removal of moisture, dirt, and debris from the footwear of pedestrians through the utilization of a carpet pile component. Furthermore, the utilization of a foam rubber backing also allows for either periodic heavy duty industrial-scale laundering in such standard washing machines or periodic washing and drying in standard in-home machines, both without appreciably damaging the inventive floor covering article, such as a floor mat. Additionally, the presence of integrated foam rubber protrusions within the mat structure provides an effective cushioning effect for pedestrian comfort as well as a means to prevent slippage of the article from its contacted surface.
