NOVELTY - Carbon graphene conduction printing method comprises (S100) preparing a fabric for imparting conductivity by checking the worn fabric, (S200) preparing conductive ink for imparting conductivity to the prepared fabric using water and ethanol as a diluent solvent, polyurethane resin as a binder, graphene and graphite as a conductive material and other additives, (S300) undercoat printing step of forming a base design on the fabric by passing the undercoat printing roller having the design to be expressed on the fabric and performing undercoat printing of desired design, (S400) conductive printing step of passing the printed fabric through the conductive printing roller to perform the conductive printing to harmonize with the undercoat printing, (S500) drying the printed fabric, (S600) forming a coating layer on the surface of dried fabric to prevent moisture or foreign substances from contacting the conductive ink and impairing the conductivity, and (S700) pressing the conductive print. USE - Used as carbon graphene conduction printing method. ADVANTAGE - The method: is economical; improves the quality and durability of the conductive fabric; continuously maintains the conductivity by solving the problem of reduced or lost conductivity due to micro-cracks caused by adhesion of the binder even when the fabric to which conductivity is applied is used for a long period of time; and prevents safety accidents e.g. explosions due to static electricity generated during the work process. DETAILED DESCRIPTION - Carbon graphene conduction printing method comprises (S100) preparing a fabric for imparting conductivity by checking the worn fabric, pressing via press roller at 180-230 degrees C, and flattening the fabric surface to increase the penetrability of ink in the conductive printing process by increasing the texture of the fabric, (S200) preparing conductive ink for imparting conductivity to the prepared fabric using water and ethanol as a diluent solvent, polyurethane resin as a binder, graphene and graphite as a conductive material and other additives, (S300) undercoat printing step of forming a base design on the fabric by passing the undercoat printing roller having the design to be expressed on the fabric and performing undercoat printing of the desired design, (S400) conductive printing step of passing the printed fabric through the conductive printing roller to perform the conductive printing to harmonize with the undercoat printing, (S500) drying the printed fabric by passing it through a drying chamber at 130-150 degrees C for at least 1 minute, (S600) forming a coating layer on the surface of the dried fabric to prevent moisture or foreign substances from contacting the conductive ink and impairing the conductivity, and (S700) pressing the conductive print by applying a pressure of 30-50 tons in a state in which the conductive ink is maintained at a temperature of 180-230 degrees C on at least one side of the printed fabric and stretching to prevent the conductivity of the fabric from which the surface treatment has been completed.
