Title: ARTIFICIAL HAIR FIBER
Abstract:
[Problem] To provide a polyvinyl chloride-type artificial hair fiber that exhibits an excellent low glossiness, is grippable during weaving, and can be stably spun. [Solution] The artificial hair fiber according to the present invention uses a polyvinyl chloride resin composition that contains, in a prescribed proportion, (A) a polyvinyl chloride resin having a viscosity-average degree of polymerization of 450 to 1700 and (B) a crosslinked vinyl chloride resin having a viscosity-average degree of polymerization for the tetrahydrofuran-soluble component of 1800 to 2300, wherein the difference between the viscosity-average degree of polymerization of the polyvinyl chloride resin (A) and the viscosity-average degree of polymerization of the THF-soluble fraction of the crosslinked vinyl chloride resin (B) is in a prescribed range. In addition, the shape of the cross section of the artificial hair fiber has a first projection, a second projection and a third projection, and their length and width satisfy a prescribed condition.
