Acrylic fiber for artificial hair, crimped acrylic fiber for artificial hair, hair ornament product including the same, and production method therefor

Abstract

The present invention relates to an acrylic fiber for artificial hair containing an acrylic copolymer. The dry-heat shrinkage ratio of the acrylic fiber after dry-heat treatment at 90 to 180° C. for 30 minutes is 30 to 70%, and the torsional rigidity thereof is 0.3 to 2.0 mg·cm2. Also, one or more embodiments of the present invention relate to a crimped acrylic fiber for artificial hair containing an acrylic copolymer. In the crimped acrylic fiber, the number of crimps is 10 or more crimps per 10 cm, and the crimp height is 1.5 mm or more. In addition, in ten continuous crimps, at least two crimps differ in crimp width and at least two crimps differ in crimp height, while the crimps are formed in two or more different crimp directions.
