Problems solved by technology

For fibers with external metal plating, their electrical conductivity is not ideal, and the chemical raw materials used in the metal plating process will also pollute the environment
The metal wire is used as a conductive fiber, and the traditional conductive metal is not much different. If it is added when weaving the fabric, extra attention must be paid to the fabric when it is folded, and the comfort of the fabric will be greatly reduced.

Description

technical field [0001] The invention relates to a conductive graphene fiber, a production method and a production system of the conductive graphene fiber. Background technique [0002] Conductive fiber is a kind of fiber in great demand. Compared with traditional conductive materials, conductive fiber is soft and slender, has strong fatigue resistance, and is not easy to break due to fatigue limit. Moreover, conductive fiber can also be woven into various fabrics , used to warm clothes or anti-static. Existing conductive fibers are metal-plated fibers, and some even use metal wires as conductive fibers. For the fiber with outer metallization, its conductivity is not ideal, and the chemical raw materials used in the metallization process will also pollute the environment. The metal wire is used as a conductive fiber, and the traditional conductive metal is not much different. If it is added when weaving the fabric, extra attention must be paid to the fabric when it is folde...
