  • Publication number: 20130090030
    Abstract: A method of treatment for synthetic or natural fibre or yarn includes coating the fibre/yarn with a dispersion of carbon nanotubes in a coating composition which is cured by actinic radiation, such as UV, to provide a flexible conductive layer on the fibre/yarn. The liquid coating composition is sheared along the direction of a long axis of the yarn as it is applied to the yarn whereby the carbon nanotubes are substantially aligned prior to curing of the coating layer to provide improved longitudinal conductance. The method provides conductive fibre/yarn, from which anti-static textiles and fabrics can be formed, by treatment of conventional fibre/yarn and in a method with low energy consumption. The improved conductance allows thin or partial (e.g.

    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.

  • Patent number: 6245694
    Abstract: Automotive bedliners (e.g., for pickup trucks) are formed from a sheet of thermoplastic material having electrically conductive fibers embedded in a surface thereof in an amount sufficient to render said sheet electrically conductive. The bedliners are most preferably formed of a thermoplastic material (e.g., a polyolefin, such a polyethylene and/or polypropylene) having a matrix of electrically conductive fibers physically embedded in at least one side thereof. By physically embedding the conductive fibers in a surface of the bedliner, the fibers are capable of establishing electrical continuity between the bedliner and the pickup truck bed thereby effectively dissipating static electrical charges.
