Method for producing variable color wire rod

The invention discloses a method for producing a variable color wire rod, which relates to the technical field of wire rod production. The method comprises the following steps: a)selecting a raw material; b)fusing the material; c)configuring color masterbatch; d)performing secondary fusing; e)extruding; and f) granulating. According to the production method, the color of the produced wire rod can be changed by following with illumination and temperature, the wire rod can be used for producing power lines, data lines and earphone cords, problem of signal color of the integral wire rod in prior art can be solved, individual characteristic can be added, various color of a derivative product prepared by the wire rod in practical usage can fill the disadvantage of single color of the original wire rod.
