  • Patent number: 6458724
    Abstract: The invention is directed to multi-layered textile fabrics having a plurality of polymeric coating layers of polyurethane and/or polysiloxane coated thereon. The coating layers are applied to such multi-layered woven textile fabric substrates having preconfigured air-holding cavities therein to form an improved air-holding vehicle restraint system, such as an air bag or side air curtain with superior air-holding characteristics. In certain instances, the multi-layered textile fabrics are coated on one side only, and in others they may be coated on both sides, i.e., opposed first and second surfaces. The layers of the multi-layered fabric can then be joined by means of heat sealing, RF welding or combinations thereof, for purposes of forming an air bag or side air curtain without the need for sewing or stitching. The coated fabrics facilitate manufacture of air bags, side curtains or the like with both reduced cutting and sealing steps than fabrics of the prior art.

    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.

In the first step, essentially all of the strands of the fiberglass are coated with the resin solvent mixture as well as most of the interstices or openings, although some of the interstices or openings have holes where the coating does not completely fill in. This first coating is then partially cured to the extent that it will not redissolve in a second coating of the same resin solution. The coated fiberglass with partially cured resin thereon is then given a second coating of the same resin mixture which coats the first coating and fills in any holes in the first coating. This second coating is then partially cured, which advances the cure of the first coating and results in an impregnated fiberglass cloth structure for use as sticker sheets. This substantially reduces pinholing.

  • Patent number: 5773371
    Abstract: A method for coating cloth especially fiberglass sheets with a resin and resulting structure is provided. The coating is performed in two steps. In the first step, essentially all of the strands of the fiberglass are coated with the resin solvent mixture while maintaining the interstices or openings essentially free of the solvent mixture. This first coating is then partially cured to the extent that it will not redissolve in a second coating of the same resin solution. The coated fiberglass with partially cured resin thereon is then given a second coating of the same resin mixture which coats the first coating and fills in the interstices between the fibers. This second coating is then partially cured, which advances the cure of the first coating and results in an impregnated fiberglass cloth structure for use as sticker sheets.

  • Patent number: 5763332
    Abstract: Wet-like cleaning wipes and similar articles that are particularly useful in removing perianal soils. These wipes comprise a carrier comprising at least one polarphobic region, an optional, preferred substrate such as tissue paper web, and an emulsion applied to the carrier. The emulsion comprises a continuous external lipid phase and a dispersed internal polar phase. The continuous lipid phase of the emulsion is sufficiently brittle that it ruptures when subjected to low shear pressures during use to release the dispersed internal phase. Inclusion of the polarphobic region allows the ability to control flow of the internal water phase components following rupture of the emulsion.

  • Patent number: 5747392
    Abstract: Water repellant, stain resistant, weatherable, and transfer printable coated fabrics are provided by coating synthetic woven textile fabric with an IPN (interpenetrating polymer network)--containing aqueous coating which is composed of both acrylic and polyurethane lattices also including a crosslinker. Upon elevated temperature cure, the coating forms an interpenetrating polymer network and provides a non-leather like fabric with the hand and feel of high quality woven fabric with the ability to transmit water vapor while being virtually totally water repellant.
