To prepare the conductive fabric, the conductive carbon black was prepared by milling dispersion. The effect of carbon black particles, the content of carbon black, coating times, the content of binder, curing time and temperature on the properties of the conductive polyester (PET) coated fabric were studied. The properties of the PET coated fabric including the surface resistance, washing fastness, rubbing fastness, breaking strength, and elongation performance were tested. The test results showed that when the content of the conductive carbon black was 15%, conductive carbon black particle was 200nm, the coating times was four, the concentration of binder was 40%, curing time and tempreture were 150℃and 3 min, the surface resistance of the PET coated fabric was minimized, the dry friction and wash fastness of the coated fabric could reach 5 grade, and the surface resistance of the PET coated fabric increased after washing.
