ACRYLIC FIBER FOR ARTIFICIAL HAIR, METHOD FOR MANUFACTURING SAID FIBER, AND HEADDRESS PRODUCT CONTAINING SAID FIBER

The present invention pertains to an acrylic fiber for artificial hair comprising an acrylic copolymer in which acrylonitrile, vinyl chloride and/or vinylidene chloride, and a sulfonate-group-containing vinyl monomer are copolymerized, wherein the acrylic fiber for artificial hair contains an organic solvent in an amount of 0.1-3% by mass with respect to the total mass of the acrylic fiber for artificial hair, the organic solvent being capable of dissolving the acrylic copolymer, and the average surface roughness of the acrylic fiber for artificial hair being 5900 [mu]m or less in a 40 [mu]m long by 80 [mu]m wide region on a fiber side face. This acrylic fiber for artificial hair can be fabricated by wet-spinning a spinning dope containing 8-16 parts by mass of water with respect to 100parts by mass of the acrylic copolymer. The present invention thereby provides an acrylic fiber for artificial hair that has excellent performance in regard to curl setting and hackling using hot water, a method for manufacturi
