Abstract: A composite facer material for use with cementitious wallboards, where the composite facer is embedded in a top and bottom face thereof. The composite facer material, in a most preferred embodiment, comprises two layers. The first layer is preferably a carded polyester nonwoven mat, which is bonded to a second layer comprising preferably a tri-directional laid scrim fabric reinforcement layer made of continuous glass fibers. The two layers are preferably bonded together using an acrylic adhesive, which offers superior adhesion between the layers as well as superior adhesion between the composite facing material and the cementitious core.

Abstract: The present invention relates to a process for making an electromagnetically conductive textile, having a conductivity gradient through the thickness of the fabric, comprising the steps of (a) forming a knit, woven or nonwoven fabric characterized by (i) a variation in fiber surface area per unit of volume, through the thickness of the fabric; or (ii) a variation in susceptibility of the fibers to coating, through the thickness of the fabric; and (b) applying a conductive coating to fibers in the fabric, to create a conductivity gradient through the thickness of the fabric.

Abstract: The present invention relates generally to a static dissipative textile having an electrically conductive surface achieved by coating the textile with an electrically conductive coating in a variety of patterns. The electrically conductive coating is comprised of a conducting agent and a binding agent, and optionally a dispersing agent and/or a thickening agent. The static dissipative textile generally comprises a fabric which may be screen printed or otherwise coated with a conductive coating on the backside of the fabric so that the conductive coating does not interfere with the appearance of the face of the fabric. The economically produced fabric exhibits relatively permanent static dissipation properties and conducts electric charge at virtually any humidity, while the conductive coating does not detrimentally affect the overall appearance or tactile properties of the fabric.

Abstract: This invention relates to novel airbag coating compositions and systems comprising pre-expanded or non-expandable microspheres that provide effective insulation for the target airbag fabric during exothermic inflation. The inventive airbag fabrics are either pre-calendered prior to application of this composition or are coated through a gap (floating) knife method with such heat-expandable microsphere-containing compositions. The coated airbag fabrics and cushions may then be heated to evaporate the solvent within the coating composition. The resultant fabric thus exhibits the presence of the microsphere constituents of the coating compositions both within the interstices between the individual yarns of the fabric and over the raised yarns of the fabric.

Abstract: The present invention relates to an electromagnetically conductive textile fabric comprising conductive fibers arranged to provide a conductivity gradient through its thickness. The fibers may be intrinsically conductive or coated with a conducting material and the gradient can be related to variances in fiber density, fiber diameter (fineness) and fiber conductivity. The fabric can be used to eliminate or reduce electromagnetic interference (EMI) in various applications.

Abstract: A patterned conductive textile is provided by applying a finish to selected parts of a fabric which inhibits the formation of a conductive polymer coating on those areas. A conductive polymer is then oxidatively synthesized onto the remaining areas from an aqueous solution comprising the starting monomer, an oxidizing agent, and, optionally, a doping agent or counterion. The areas with the inhibitor finish remain substantially free of conductive polymer and a pattern of conductive and nonconductive areas is thus produced.

Abstract: A method of making a patterned conductive textile is provided by depositing a conductive polymer film on the fabric to provide a resistivity of 1000 ohms per square or less, coating selected areas of the fabric with a protective film, to protect the conductive polymer from a chemical etching agent, to provide an oxygen barrier and to retain areas of high conductivity, applying a chemical etching agent to the fabric thereby degrading the conductive polymer film on areas of the fabric which have not been coated with the protective film and create areas of low conductivity and rinsing the fabric to remove any residual etching agent.
