METHOD FOR MANUFACTURING ARTIFICIAL HAIR FIBERS, AND ARTIFICIAL HAIR FIBERS

Document Type and Number:

WIPO Patent Application WO/2015/194521

Kind Code:

A1

Abstract:

[Problem] To provide a method for manufacturing artificial hair fibers from which dye or functional agents are not dislodged, and artificial hair fibers. [Solution] The artificial hair fibers according to the present invention are produced by mixing a fiber material, an inorganic pigment, and a functional agent before spinning, and then spinning the mixture and cutting the spun filaments. Dislodging of the inorganic pigment or functional agent is accordingly prevented. Discoloration or malfunctioning of the artificial hair fibers is thereby prevented. Also, the use of an inorganic pigment in the artificial hair fibers according to the present invention yields light resistance that is superior to that of organic dyes, and a high degree of safety in regard to skin disorders such as allergies. Furthermore, since the artificial hair fibers according to the present invention are colored by spin-dyeing, the functional agents are not covered by the dye. It is thereby possible for the functional agents to function effectively.
