METHOD AND PRODUCT TO ENHANCE ELECTRICAL CONDUCTIVITY OF FILMS CONTAINING CONDUCTIVE CARBON BLACK

摘要

Method to enhance the electrical conductivity of a carbon-containing film material (10) such as a hot melt for carpet backing. The method involves applying a plurality of arcs across the surface of the film passing under a plurality of electrodes (15) to create a plurality of small crater-like holes (25) in the surface of the film. The film material may be adhered to a carpet material and the crater-like holes (25) acting to increase the anti-static property of the carpet.
