  • Patent number: 7654289
    Abstract: A double layer forming fabric for a papermaking machine is warp-tied, all the warp yarns comprising binder pairs which forming a single combined path in the paper side surface. The pair members exchange positions at an exchange point between successive path segments and are laterally displaced in relation to each other at and between each exchange point. For each successive pair, an order of insertion of the first and second members in relation to each other into the weave is inverted in relation to the order of insertion for members of the immediately preceding pair, such that each first member is adjacent to the first member of the adjacent pair at the closest exchange point, and each second member is adjacent to the second member of the adjacent pair at the closest exchange point. The fabric has improved drainage uniformity leading to improved paper formation and reduced sheet marking.

  • 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: 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: 6660668
    Abstract: There is disclosed a woven webbing structure, which resists interwoven yarns from coming out from the surface of the webbing due to bending, or the like. This is achieved without any significant reduction in the strength or energy absorptivity of the webbing. The webbing includes warps that each have a cored yarn and a side yarn, and wefts interwoven therein. The cored yarn is set such that the elongation percentage thereof is smaller than, or the extensional rigidity thereof is larger than, that of the side yarn, and is twisted by single twisting or the like. As a result, unevenness is formed on the surface of the cored yarn and friction between the cored yarn and other yarns, that is, the side yarn or the weft increases. The frictional force between yarns functions for resisting free movement of the cored yarn due to bending of the webbing, thereby making it possible for the cored yarn to resist coming out from the surface of the webbing.
