The present invention relates to an acrylic fiber for artificial hair, which is formed from an acrylic polymer, wherein the acrylic polymer contains acrylonitrile, vinyl chloride and/or vinylidene chloride, and a sulfonic acid-containing vinyl monomer in amounts of 29.5 to 79.5% by weight, 20 to 70% by weight and 0.5 to 5% by weight, respectively, relative to the whole weight of the acrylic polymer, and the content of an organic solvent capable of dissolving the acrylic polymer therein in the acrylic fiber is 0.1 to 3% by weight. The acrylic fiber for artificial hair can be produced by extruding a spinning raw solution containing an acrylic polymer through a spinning nozzle to form a yarn, drawing the yarn to produce a primary draw yarn, washing the draw yarn with water, and impregnating the primary draw yarn that has been washed with water with an organic solvent capable of dissolving the acrylic polymer therein. Provided are: an acrylic fiber for artificial hair, which has good curl set properties with hot water; a method for producing the acrylic fiber; and a head decoration product comprising the acrylic fiber. |
