    Abstract: A polyvinyl alcohol (PVA)-based airbag base fabric aqueous coating material is provided. Blocked polyisocyanate component (B-NCO) and liquid polyol are added, respectively, as a cross-linkage improver and a plasticizer. The B-NCO is composed of or based on a medium-molecular-weight form as a polyether-modified prepolymer, used concurrently with a low-molecular-weight form in a small amount. The base fabric coating material is applied on one or both of the sides of a cloth of the base fabric, and heated. Thus the acquired coating film is a water-insoluble coat and the coat shows excellent heat and moisture resistance (hot water resistance) and flexibility.

    Abstract: A moisture vapor permeable, water impermeable composite sheet material is provided which is suitable for use as a housewrap material, and is also useful for other applications such as tarpaulins, or as covers for automobile, boats, patio furniture or the like. The composite sheet material includes a nonwoven substrate and an extrusion-coated polyolefin film layer overlying one surface of the substrate. The nonwoven substrate is comprised of polymeric fibers randomly disposed and bonded to one another to form a high tenacity nonwoven web. The nonwoven substrate has a grab tensile strength of at least 178 Newtons (40 pounds) in at least one of the machine direction (MD) or the cross-machine direction (CD). The extrusion coated polyolefin film layer is intimately bonded to the nonwoven substrate. The film layer has micropores formed therein to impart to the composite sheet material a moisture vapor transmission rate (MVTR) of at least 35 g/m2/24 hr. at 50% relative humidity and 23° C.

  • Patent number: 7915183
    Abstract: A barrier coating for paper and a method of making the coated paper using a wax coating composition containing an inorganic mineral filler is provided. The inorganic mineral filler imparts a viscosity to the wax coating composition similar to the viscosity of the wax coating composition in the absence of the inorganic mineral filler. Coated paper products are also provided.

  • Patent number: 7910502
    Abstract: Ballistic resistant articles having excellent resistance to deterioration due to liquid exposure. More particularly, a ballistic resistant structures and articles formed from a hybrid of woven and non-woven fibrous components that retain their superior ballistic resistance performance after exposure to liquids such as sea water and organic solvents, such as gasoline and other petroleum-based products. The hybrid structures are particularly useful for the formation of or for use in conjunction with soft, flexible body armor.

  • Patent number: 7820561
    Abstract: Coated, water-vapor-pervious and fungus resistant wovens, their production and also their use as sun and weather protection articles, a precleaned industrial woven fabric being treated at least once with an aqueous impregnant comprising a fungicide and a hydrophobicizer. The fabric thus impregnated and then dried is subsequently coated with an aqueous polyurethane dispersion which likewise contains a fungicide. After drying, the coated fabric is reimpregnated. The wovens are notable for fungus resistance, good water vapor perviousness and good watertightness against a high hydrohead in particular.

  • Patent number: 7811950
    Abstract: A polyester filament nonwoven ply is suitable for roofing and roof-sealing webs and has a latent shrinkage force which counteracts drafting forces which may subsequently occur as the result of stresses or during thermal processing operations. The roofing webs thus remain dimensionally stable even when exposed to heat. The shrinkage force is obtained according to the claimed process by drafting the ply accordingly in a drafting mechanism arranged after a dryer.

  • Patent number: 7786028
    Abstract: A flexible nonwoven mat of polymeric fibers is liquid water transmission resistant and is particularly well suited for use as a prefabricated building construction underlayment. The polymeric fibers may be standard polymeric fibers or sheathed polymeric fibers that have fiber sheaths with a lower softening point temperature than the softening point temperature of the fiber cores. Preferably, the polymeric fibers are spunbond fibers and are bonded together through the application of heat and pressure. Where the fibers are sheathed fibers, interstices of the nonwoven mat are at least partially filled by a portion of the polymeric material of the sheaths that is dispersed into the interstices to reduce the porosity of the mat.

  • Patent number: 7749923
    Abstract: A facing laminate for insulation products includes: a foil or metallized polymeric film sheet layer forming an inner layer of the laminate that is adapted be bonded directly to a surface of an insulation product; a paper composite sheet layer, which may include synthetic and/or inorganic fibers, forming an outer exposed layer of the laminate; and a scrim intermediate and bonded to the foil or metallized polymeric film sheet and paper composite sheet layers. The facing laminate may include a humectant and/or a water, oil, and/or grease repellant component. The paper composite sheet layer of the laminate exhibits greater dimensional stability and reduced wrinkling when the laminate is exposed to conditions of high humidity. Insulation products to be faced with this facing laminate include pipe insulation, duct board, duct wrap insulation, metal building insulation, and other building insulation products.
