Antistatic carpet tile and method of manufacturing such carpet tile.

摘要

An antistatic or electrically conductive carpet tile and a method of producing such carpet tile, which method comprises forming a plurality of separate columns o electrically conductive material (32), extending generally perpendicularly between the back surface of the carpet tile and the face of the carpet tile, the electrically conductive columns formed in a non-electrically conductive thick backing layer, so as to provide an electrically conductive path from the face of the carpet to ground. An antistatic carpet which comprises a fibrous face (14) secured to a primary backing layer (16), an electrically conductive precoating layer (18) on the backing layer, and a nonelectrically conductive backing layer (20) and a plurality of columns of electrically conductive material, such as electrically conductive polymeric ink, extending from the back surface of the carpet tile to the nonelectrically conductive backing layer and into contact with the electrically conductive precoat layer or face.
