Patent ID: 8372766

Claim:
A nonwoven material comprising: a nonwoven base web containing pulp fibers in an amount of at least about 50% by weight, the nonwoven base web further comprising conductive fibers in an amount of at least about 1% by weight, the conductive fibers comprising carbon fibers; wherein the carbon fibers contain carbon in an amount greater than about 90% by weight; wherein the conductive fibers are present in the nonwoven base web so as to form at least one conductive zone and at least one nonconductive zone, the at least one conductive zone having a resistance of less than about 1500 Ohms/square; wherein the nonwoven base web comprises a single ply web and is formed via depositing the fibers generally simultaneously in a wet laid process; and wherein the at least one conductive zone and at least one nonconductive zone can be positioned either generally vertically or generally horizontally with respect to one another in the single ply web via the wet laid process, such that the at least one conductive zone is a mixture of pulp fibers and conductive fibers and the at least one nonconductive zone lacks conductive fibers; and the nonwoven base web is calendared.
