Abstract
A composite sheet material for making industrial air pollution control filters where the composite sheet material includes a porous, non-filtering, electrostatic dissipation substrate on which is bonded a thin, high efficiency filter layer. Before application of the filter layer, both sides of the porous substrate are imprinted with a pattern of spaced apart, parallel lines of conductive ink which penetrate over 50% of the substrate thickness so that the pattern on one side meets at intersections within the substrate with the pattern on the opposite side to provide a series of continuous, uninterrupted electrostatic discharge pathways running through the substrate to dissipate static electricity charges. The composite sheet material may be pleated and formed as a tube for making baghouse filter cartridges.
