Abstract
The invention contemplates a multi-layer electrically conductive web for safely and quickly discharging personnel-accumulated static electricity, and suitable as an upholstery material. The web comprises an upper continuous polymeric layer of relatively low conductivity, in the order of 10.sup.8 ohms per square, bonded to an underlying continuous polymeric layer of much greater conductivity, in the order of 10.sup.2 ohms per square, and provision is made for electrically grounding the underlying layer, illustratively by casting to the intermediate layer a continuous bottom layer of expanded polymeric material of relatively low conductivity. In the preferred embodiment, a fabric base is laminated to the bottom layer of the web.
