[0002] Conductive fiber refers to chemical fiber or metal fiber, carbon fiber, etc. spun by mixing conductive medium into polymer. It has excellent performance in eliminating and preventing static electricity, which is much higher than that of antistatic fiber, and its specific resistance value is persistent and basically unaffected by humidity.
