Abstract
Conductive nonwoven webs are disclosed. The nonwoven webs contain pulp fibers combined with conductive fibers. In one embodiment, the webs are made in a wetlaid tissue making process.
Claims22
A nonwoven material comprising:
- A nonwoven first base web containing pulp fibers in an amount of at least about 50% by weight, the nonwoven first base web further comprising conductive fibers in an amount of at least about 1% by weight, the conductive fibers consisting of carbon fibers, metallic fibers, conductive polymeric fibers, metal coated fibers, or mixtures thereof, the nonwoven base web including at least one conductive zone that has a resistance of less than about 1500 Ohms/square, the nonwoven first base web being an uncreped, wetlaid web;
- and
- further comprising a laminate wherein the wetlaid web is laminated to a nonconductive material;
- and
- wherein the laminate comprising first base web is attached to a second base web, each of the first and second base webs comprising a single ply web containing distinct layers of fibers, each single ply web of said first and second base webs including at least a first layer and a second layer and wherein conductive fibers are contained in the second layer of said base webs, the second layer of the first base web being attached to the second layer of the second base web.
