The anti-static yarn may take the form of a staple, continuous filament or monofilament and may be a carbon content acrylic anti-static fiber, a silver coated nylon continuous filament, a nylon monofilament coated with carbon, or an acrylic fiber carbon coated. After being woven, the fabric is typically resin treated with a heat-resistant resin.
