NOVELTY - Conductive graphene polyester fiber has conductivity of 7.8-8.5x 10-7 S/cm and a breaking strength of 5.7-6 cN/dtex. USE - Conductive graphene polyester fiber. ADVANTAGE - The conductive graphene polyester fiber has high conductivity, good compatibility and is distributed uniformly in the fiber product. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for producing conductive graphene polyester fibers, which involves: (A) preparing a graphene powder dispersion liquid; (B) dispersing graphene powder in an aqueous solution containing sodium silicate and sodium metasilicate; (C) adding 4-7% dispersant and adjusting the temperature to 45-50 degrees C; and (D) stirring for 30 minutes to obtain a polystyrene powder dispersion.
