Apparatus for manufacturing carbon nanotube fiber

An apparatus for manufacturing a carbon nanotube fiber, comprising:

• a cylindrical high-temperature reactor body having a reaction zone;
• an inlet for feeding a spinning material and a carrier gas into the reaction zone of the body;
• a heater for heating the reaction zone;
• an outlet provided at a bottom of the body so as to discharge a carbon nanotube fiber;
• a winder for collecting the discharged carbon nanotube fiber;
• a guide provided between the outlet and the winder;
• and
• a voltage supplier for applying a voltage to the guide,
• wherein the voltage is applied to the discharged carbon nanotube fiber to remove impurities from the carbon nanotube fiber.
