Conductive Nylon has an electrically conductive carbon suffused onto the surface. This coating is durable but not indestructible. In abrasive applications it wears at about the same rate as the rest of the fiber.  Its conductivity is unaffected by humidity and solvents, except strong acids and will not crack off during flexing. When using the conductive fiber, it is necessary to have a conductive path from the fiber to ground.
