Abstract

An artificial hair which is composed of synthetic fibers such as acrylic fibers or vinyl chloride fibers and which is characterized in that the cross section of each fiber has a shape consisting of one major axis and at least two minor axes nearly perpendicular to the major axis and that the single-fiber fineness is 25 to 70 dtex. This artificial hair is soft to the touch and bulky (voluminous) to impart a good feel to hair accessories and exhibits excellent combing properties and braidability, thus giving hair accessories (such as wigs, hairpieces, braids, extension hair and doll hair) which have excellent feel and settability.

Claims (17)

1. A fiber for artificial hair,

comprising a transverse cross sectional shape formed of a single major axis and at least two minor axes substantially orthogonal to the major axis, in which two or three “+” are apparently put horizontally in a row,

wherein a single yarn fineness is 25 to 70 dtex.

2. The fiber for artificial hair according to claim 1 , comprising at least one member selected from an acrylic synthetic fiber and a vinyl chloride synthetic fiber.

3. The fiber for artificial hair according to claim 2 , wherein the acrylic synthetic fiber comprises a polymer containing acrylonitrile in a proportion of 30% by weight or more in a resin component.

4. Artificial hair,

comprising a synthetic fiber having a transverse cross sectional shape formed of a single major axis and at least two minor axes substantially orthogonal to the major axis, in which two or three “+” are apparently put horizontally in a row,
