(57) [Summary] [Problem] To provide an acrylic fiber having a novel texture and touch, which has good strength for practical use, excellent hygroscopicity, and good blending of protein-based natural fine particles in the fiber. [Structure] Protein-based natural fine particles and a surfactant are added to an acrylic polymer stock solution, mixed and spun. The protein-based natural fine particles and the disulfide bond cleaving agent are added to an acrylic polymer stock solution, mixed and spun. |
