Artificial hair fiber

Abstract

An artificial hair fiber is superior in productivity and flame retardance, and is suppressed in color unevenness. An artificial hair fiber, including polyamide; and 5 to 40 parts by mass of bromine flame retardant and 0.01 to 10 parts by mass of pigment processing pigment with respect to 100 parts by mass of the polyamide; wherein the pigment processing pigment includes a colorant and a dispersant; the dispersant is contained by 20 to 80 mass % with respect to 100 mass % of total amount of the colorant and the dispersant; the dispersant includes one or more selected from the group consisting of montanoic acid metallic salt, montanoic acid wax, polyethylene wax, and fluorine wax, is provided.

1 . An artificial hair fiber, comprising:
 polyamide; and   5 to 40 parts by mass of bromine flame retardant and 0.01 to 10 parts by mass of pigment processing pigment with respect to 100 parts by mass of the polyamide; wherein
 the pigment processing pigment comprises a colorant and a dispersant; 
 the dispersant is contained by 20 to 80 mass % with respect to 100 mass % of total amount of the colorant and the dispersant; 
 the dispersant comprises one or more selected from the group consisting of montanoic acid metallic salt, montanoic acid wax, polyethylene wax, and fluorine wax. 
   
     
     
         2 . The artificial hair fiber of  claim 1 , wherein the dispersant comprises the montanoic acid metallic salt. 
     
     
         3 . The artificial hair fiber of  claim 2 , wherein the montanoic acid metallic salt is calcium montanate. 
     
     
         4 . The artificial hair fiber of  claim 1 , wherein the colorant comprises at least one selected from the group consisting of Pigment Black 7, Pigment Red 149, Pigment Yellow 147, Solvent Yellow 163, and Pigment Violet 19.
