Abstract
An acrylic fiber for artificial hair includes an acrylic polymer, wherein the acrylic polymer includes 29.5 to 79.5% by mass of acrylonitrile, 20 to 70% by mass of vinyl chloride and/or vinylidene chloride, and 0.5 to 5% by mass of a vinyl monomer comprising a sulfonic acid group. The acrylic fiber for artificial hair includes 0.3 to 2% by mass of a good solvent for the acrylic polymer and 0.1 to 5% by mass of a compound comprising an epoxy group.

An acrylic fiber for artificial hair comprising an acrylic polymer,
- wherein the acrylic polymer comprises 29.5 to 79.5% by mass of acrylonitrile, 20 to 70% by mass of vinyl chloride and/or vinylidene chloride, and 0.5 to 5% by mass of a vinyl monomer comprising a sulfonic acid group,
- wherein the acrylic fiber for artificial hair further comprises:
- 0.3 to 2% by mass of a solvent for the acrylic polymer;
- and 0.1 to 5% by mass of a compound comprising an epoxy group, and
- wherein the compound comprising an epoxy group is one or more of the group consisting of a polymer comprising, glycidyl methacrylate, a polymer comprising glycidyl acrylate, an epoxidized vegetable oil, a glycidyl ether-type epoxy resin, a glycidyl amine-type epoxy resin, a glycidyl ester-type epoxy resin, and a cyclic aliphatic-type epoxy resin.
A method for producing an acrylic fiber for artificial hair comprising an acrylic polymer, the method comprising:
- preparing a spinning solution comprising the acrylic polymer, a compound comprising an epoxy group, and a solvent for the acrylic polymer;
- and

- wherein the acrylic fiber comprises:
- 0.3 to 2% by mass of the solvent for the acrylic polymer;
- and 0.1 to 5% by mass of the compound comprising an epoxy group, and
- wherein the compound comprising an epoxy group is one or more of the group consisting of a polymer comprising glycidyl methacrylate, a polymer comprising glycidyl acrylate, an epoxidized vegetable oil, a glycidyl ether-type epoxy resin, a glycidyl amine-type epoxy resin, a glycidyl ester-type epoxy resin, and a cyclic aliphatic-type epoxy resin.
A hair ornament product comprising an acrylic fiber for artificial hair comprising an acrylic polymer,
- wherein the acrylic polymer comprises 29.5 to 79.5% by mass of acrylonitrile, 20 to 70% by mass of vinyl chloride and/or vinylidene chloride, and 0.5 to 5% by mass of a vinyl monomer comprising a sulfonic acid group,
- wherein the acrylic fiber for artificial hair comprises 0.3 to 2% by mass of a solvent for the acrylic polymer and 0.1 to 5% by mass of a compound comprising an epoxy group, and
- wherein the compound comprising an epoxy group is one or more of the group consisting of a polymer comprising glycidyl methacrylate, a polymer comprising glycidyl acrylate, an epoxidized vegetable oil, a glycidyl ether-type epoxy resin, a glycidyl amine-type epoxy resin, a glycidyl ester-type epoxy resin, and a cyclic aliphatic-type epoxy resin.
