Abstract
Abstract An antistatic laminated fabric having conductive tie yarns and a non-woven scrim which is laminated between two conductive sheets of PVC film. In one embodiment, all yarns in the warp direction are of the same denier, and the yarns in the weft direction are likewise all of the same denier. In another embodiment, heavier yarns are laid in regular intervals in both fabric directions.
