Artificial hair fibers, head accessory including same, and method for manufacturing same

Abstract

Fibers for artificial hair containing resin particles adhering to the fiber surface are provided. The amount of the resin particles adhering to the fiber surface is 0.3% omf or more and 1.1% omf or less. The average particle diameter of the resin particles is 1 μm or more and 20 μm or less. A method for producing the fibers for artificial hair, includes applying a resin emulsion having an average particle diameter of 350 nm or more to the fiber surface, in an amount of 0.3% omf or more and 1.1% omf or less on a solid basis. The fibers for artificial hair having an excellent combing property and a gloss close to human hair, hair ornament products including the same, and a method for producing the same are provided.

         2 . The fiber for artificial hair according to  claim 1 , wherein the resin particles are solid at room temperature. 
     
     
         3 . The fiber for artificial hair according to  claim 1 , wherein the resin particles comprise the polyurethane-based resin. 
     
     
         4 . The fiber for artificial hair according to  claim 1 , wherein the fiber for artificial hair comprises at least one selected from the group consisting of polyester-based fiber, polyvinyl chloride-based fiber, acrylonitrile-based fiber, polyamide-based fiber, and polyphenylene sulfide-based fiber. 
     
     
         5 . The fiber for artificial hair according to  claim 4 , wherein the acrylonitrile-based fiber is a modacrylic fiber. 
     
     
         6 . A method for producing the fiber for artificial hair according to  claim 1 , comprising applying a resin emulsion to the fiber surface, wherein:
 an average particle diameter of the resin emulsion is 350 nm or more, and   an application amount of the resin emulsion on a solid basis is 0.3% omf or more and 1.1% omf or less.   
     
     
         7 . The method according to  claim 6 , wherein the resin emulsion has a viscosity at 30° C. of 0.1 mPa·s or more and 1000 mPa·s or less. 
     
     
         8 . The method according to  claim 6 , wherein the resin emulsion has a pH of 4 or more and 9 or less. 
     
     
         9 . The method according to  claim 6 , wherein the resin particles are solid at room temperature. 
     
     
         10 . The method according to  claim 6 , wherein the resin particles comprise the polyurethane-based resin. 
     
     
         11 . The method according to  claim 6 , wherein the fiber for artificial hair comprises at least one selected from the group consisting of polyester-based fiber, polyvinyl chloride-based fiber, acrylonitrile-based fiber, polyamide-based fiber, and polyphenylene sulfide-based fiber. 
     
     
         12 . The method according to  claim 11 , wherein the acrylonitrile-based fiber is a modacrylic fiber. 
     
     
         13 . A hair ornament product comprising the fiber for artificial hair according to  claim 1 . 
     
     
         14 . The hair ornament product according to  claim 13 , wherein the hair ornament product comprises one selected from the group consisting of a hair wig, a hairpiece, weaving hair, a hair extension, braided hair, a hair accessory, and doll hair. 
     
     
         15 . The hair ornament product according to  claim 13 , wherein the resin particles are solid at room temperature. 
     
     
         16 . The hair ornament product according to  claim 13 , wherein the resin particles comprise the polyurethane-based resin.
