Abstract: Provided is a manufacturing method of a neoprene containing carbon nanotubes (CNT), and more particularly, a manufacturing method of a neoprene which contains the CNT having low weight and high tensile strength, and also contains vacuum glass balls having an excellent heat insulation effect such that elongation and a heat retaining property are excellent, and anions and far infrared rays are emitted. In a neoprene fabric manufactured by a method of manufacturing a neoprene containing carbon nanotubes of the present invention, the carbon nanotubes are uniformly distributed so that the fabric has good flexibility and is strong. Anions and far infrared rays are emitted as well, and the heat retaining property is excellent.
