Fibers capable of conducting electricity to ground.
Most conductive fibers contain carbon, graphite or stainless steel. Static-dissipative and conductive carpets used in static-sensitive commercial environments are carbon-coated on the exterior of the fiber. External conductivity allows static charges to make contact with the conductive element in the fibers, then safely discharge through the carpet layers to a ground source, such as electrical conduit.
Because conductive elements are incorporated into the material in the manufacturing process, conductivity is a permanent property.
