    Abstract: All-woven inflatable fabrics having areas of two layers and attachment points or “seams” where single layers of fabric are formed. Such single fabric layers may be constructed solely through the utilization of basket weave patterns. These specific single fabric layers provide a relatively effective manner of reducing air permeability within the entire fabric article by decreasing the possibility of yarn shifting upon inflation of the inflatable fabric. Alternatively, the presence of at least a second single fabric layer area adjacent to the first and separated by and narrow double fabric layer area can further reduce the possibility of yarn shifting in the first single fabric layer area. Such a fabric may be utilized in numerous and various applications wherein fabric inflation is desired or necessary. In particular, the inventive fabric may be incorporated within an airbag cushion.

  • 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: 6698458
    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 permeability. The inventive inflatable fabrics are primarily for use in automotive restraint cushions that 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 necessarily low permeability levels. Thus, the inventive coated inflatable airbag comprises a film laminated on at least a portion of the target fabric surface wherein the film possesses a tensile strength of at least 2,000 and an elongation at break of at least 180%.

  • Patent number: 6585006
    Abstract: A papermaker's fabric includes a base fabric structure including machine direction yarns and primary cross machine direction yarns interlacing to form a papermaking surface, wherein the machine direction yarns and primary cross machine direction yarns are interlaced in a pattern having a harness repeat of greater than two. The fabric also includes first and second companion cross machine direction yarns positioned between each pair of adjacent primary cross machine direction yarns. Each first companion cross machine direction yarn has an interlacing pattern relative to the machine direction yarns that is identical to a first of the pair of adjacent primary cross machine direction yarns, and each second companion cross machine direction yarn has an interlacing pattern relative to the machine direction yarns that is identical to a second of the pair of adjacent primary cross machine direction yarns.

  • Patent number: 6381994
    Abstract: Disclosed is a method for making a woven or knitted fabric with an excellent water transition ability, involving the steps of fabricating a woven or knitted fabric having a double weave structure by use of a polyethyleneterephthalate (PET) filament for one surface of said fabric and a divided PET/nylon-conjugated fiber for the other surface of said fabric, and subjecting said fabric to a weight loss finishing process. Since the fabric has a void size difference between the surfaces thereof in accordance with the weight loss finishing process, it can externally discharge, at a high velocity, moisture absorbed therein.

  • Patent number: 6220309
    Abstract: An all-woven inflatable fabric having areas of two layers and attachment points or “seams” where single layers of fabric are formed. Such single fabric layers are constructed solely through the utilization of basket weave patterns. These specific single fabric layers provide a relatively effective manner of reducing air permeability within the entire fabric article by decreasing the possibility of yarn shifting upon inflation of the inflatable fabric. Alternatively, the presence of at least a second single fabric layer area adjacent to the first and separated by a narrow double fabric layer can further reduce the possibility of yarn shifting in the first single fabric layer area. Such a fabric may be utilized in numerous and various applications wherein fabric inflation is desired or necessary. In particular, the inventive fabric may be incorporated within an airbag cushion.
