Beschreibung
Zusammenfassung:	An acrylic fiber for artificial hair may include an acrylic copolymer. The acrylic fiber has a fiber cross section including 2 to 4 T-shaped protrusions that extend radially from a central portion. Each of the T-shaped protrusions has an arc-shaped upper side that bulges in a direction away from the central portion. A circumradius of the fiber cross section is 40.0 to 60.0 μm. A distance between adjacent end portions of the corresponding upper sides of the adjacent T-shaped protrusions is 3.0 to 60.0 μm. An axial width is 10.0 μm or more. Torsional rigidity of the acrylic fiber is 0.30 to 2.0 mg·cm2. The acrylic fiber for artificial hair has high volume, good texture, and good twist processability, and a hair ornament may include the acrylic fiber for artificial hair.
