  • 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.

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: 6686301
    Abstract: A composition for the promotion of adhesion between a rubber formulation and a textile substrate is provided. The inventive composition comprises either a mixture of specific amine functional silanes and organo-functional silanes having reactive groups or groups with an affinity for rubber. The inventive method entails the use of the inventive composition or a silane compound having both an amine moiety and a reactive group having an affinity for rubber formulations, particularly an unsaturated carbon-carbon bond. The composition may be utilized to adhere any standard reinforcement-type textile, such as polyester or polyamide, to a standard rubber composition, such as SBR, NBR, or EPDM. A method for adhering textiles to rubber formulations is also provided involving a pre-dip, -spray, -coat, and the like, of the inventive composition on a reinforcement-type textile surface followed by the contacting of the rubber formulation.

  • Publication number: 20030144410
    Abstract: A process for the production of an ultra violet absorbing polymer latex is provided. The inventive process involves the emulsion polymerization of a benzotriazole- or benzophenone-containing monomer with a vinyl functional monomer in the presence of a chain transfer agent, preferably 1-dodecanethiol. The latex provides excellent long-lasting, easy to apply, difficult to remove, ultraviolet absorption properties for many different substrates, most notably fabrics. Different articles and fabrics coated, covered, laminated, and the like, with the inventive latex are also provided.

  • Patent number: 6584668
    Abstract: Durable non-electrically conductive metal treatments (such as coatings or finishes) for yarns and textile fabrics. Such treatments preferably comprise silver and/or silver ions; however, other metals, such as zinc, iron, copper, nickel, cobalt, aluminum, gold, manganese, magnesium, and the like, may also be present or alternatively utilized. Such a treatment provides, as one example, an antimicrobial fiber and/or textile fabric which remains on the surface and does not permit electrical conductivity over the surface. The treatment is extremely durable on such substrates; after a substantial number of standard launderings and dryings, the treatment does not wear away in any appreciable amount and thus the substrate retains its antimicrobial activity (or other property).

  • Patent number: 6576154
    Abstract: This invention relates to antimicrobial fabrics which are treated with a specific durable and regenerable halamine/chlorine system and methods of removing residual active chlorine from the target textile surface without reducing the antimicrobial activity of the textile. Such methods comprise contacting an amine-treated fabric first with a halogen-based bleach (or other halogenated liquid) to produce halamines at the fabric surface, and subsequently washing the resultant halogenated fabric with a reducing agent which removes the residual, unbonded halogen (such as chlorine) from the fabric surface but does not, surprisingly, remove the halamine halogen. The remaining halamine halogen thus provides the desired antimicrobial activity.

  • Publication number: 20030040238
    Abstract: Novel airbag coating compositions comprising at least two separate and distinct layers are provided. The first layer (base coat), being in contact with the airbag surface, comprises a composition of at least one coating material which may comprise up to 30% by parts of the total amount of material in the first layer of a silicone resin which provides excellent adhesion, excellent tensile strength, and overall lower cost than standard silicone airbag coating materials. The second layer, being a coating for the first layer, provides excellent reinforcement and blocking characteristics to permit effective potential long-term storage and optimum use upon the occurrence of a collision.

  • Publication number: 20020122908
    Abstract: Typical road surfaces are concrete, and gravel filled asphalt. They are very abrasive to fabrics that slide on those surfaces. For the new side impact curtain-type airbag, in a rollover situation, the airbag needs to protect the occupant from directly contacting the road hazard and should not deflate quickly or break when sliding on such road surfaces. We have found that a layer of elastomer can provide much better abrasion resistance than a layer of heavy industrial fabric. A Jacquard bag coated with 1.2 oz/yd2 polyurethane showed significant increase in air leakage rate after 5 cycles of concrete sliding abrasion. A 3 mil thick polyurethane film was laminated to the coated Jacquard woven airbag. After 110 cycles of sliding abrasion using the same concrete, no visual damage or change in bag leakage was observed. This finding indicates surprisingly better abrasion resistance of a thin elastomer film than a heavy industrial fabric.
