Abstract: The present invention relates to a method for producing a fiber for an artificial hair comprising: (a) pre-mixing a polyvinyl chloride resin mixture which contain 90 to 96% by weight of a polyvinyl chloride resin, 3 to 7% by weight of a stabilizer and 1 to 3% by weight of a lubricant at 90 to 140° C., mixing 20 to 80% by weight of a polyvinyl chloride resin mixture and 20 to 80% by weight of acryl-copolymer to obtain a polyvinyl chloride/acryl-copolymer blends composition; (b) melt-extruding said mixed resin composition through an extruder at 100 to 210° C. to obtain a pellet; (c) inputting said pellet into an spinning machine, melt-spinning at 150 to 220° C. to obtain filament; (d) drawing said melt-spinned filament to have a fineness of 20 to 100 denier; and (e) passing said drawn filament through heat-setting machine of 100 to 150° C. to fix the property of the filament.
