The present invention relates to a method for producing functional fiber using cinerite powder and the functional fiber produced by the method. More specifically, a method for producing functional fiber using cinerite powder according to the present invention comprises: a step of mixing a polymer with cinerite powder; a step of injecting the mixture of the polymer and the cinerite powder into a hopper which is cooled to a temperature of 10 to 30 C to cool the mixture; a step of injecting the cooled mixture of the polymer and the cinerite powder into a screw cylinder on which a transfer screw is mounted to mix the cooled mixture of the polymer and the cinerite powder; a step of extruding the mixture of the polymer and the cinerite powder mixed by the screw cylinder, and cutting the extruded mixture to prepare a master batch; a step of injecting the prepared master batch and a polymer into a hopper; a step of injecting a mixture of the polymer and the master batch injected into the hopper into the screw cylinder which has the transfer screw mounted on an inner part thereof to mix the mixture of the polymer and the master batch; a step of transferring the mixture of the polymer and the master batch mixed by the screw cylinder to a spin beam to spin fiber through a nozzle; and a step of stretching the spun fiber. A method for producing functional fiber using cinerite powder according to the present invention has a merit that the fiber is capable of being efficiently utilized as beds, non-woven fabrics, filters, automobile headliners, or trims by enabling the method to produce fiber which has excellent antibacterial, antimold and deodorizing functions, high far-infrared radiation rate and anion generation rate, and excellent UV stability and durability. |
