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 or paper making process. The pulp fibers contained in the webs may comprise softwood fibers, while the conductive fibers may comprise carbon fibers. Base webs can be produced having a resistance of less than about 100 Ohms/square in one embodiment. Once produced, the conductive material can be cut into slits that are then wound on spools. From the spools, the conductive slits can be fed into a process for making any suitable product.
