Abstract

A fiber for artificial hair, having a base fiber and a metal salt of a polymer compound that is present in at least a part of a surface of the base fiber, in which the metal salt contains at least one metal selected from the group consisting of silver, zinc, and copper. A headdress article having the fiber for artificial hair.

Claims

exact text as granted — not AI-modified
1 . A fiber for artificial hair, comprising a base fiber and a metal salt of a polymer compound that is present in at least a part of a surface of the base fiber, wherein the metal salt contains at least one metal selected from the group consisting of silver, zinc, and copper. 
     
     
         2 . The fiber for artificial hair according to  claim 1 , wherein the metal salt contains silver. 
     
     
         3 . The fiber for artificial hair according to  claim 2 , wherein a content of the metal is 5.0×10 5  to 5.0×10 −3 % by mass based on the total mass of the fiber for artificial hair. 
     
     
         4 . The fiber for artificial hair according to  claim 2 , further comprising an antistatic agent that is present in at least a part of the surface of the base fiber, wherein a content of the antistatic agent is 0.020 to 0.400% by mass based on the total mass of the fiber for artificial hair. 
     
     
         5 . The fiber for artificial hair according to  claim 2 , further comprising a silicone compound that is present in at least a part of the surface of the base fiber, wherein a content of the silicone compound is 0.010 to 0.300% by mass based on the total mass of the fiber for artificial hair. 
     
     
         6 . The fiber for artificial hair according to  claim 2 , wherein the base fiber contains a vinyl chloride-based resin. 
     
     
         7 . A headdress article comprising the fiber for artificial hair according to  claim 2 . 
     
     
         8 . The fiber for artificial hair according to  claim 1 , wherein the metal salt contains zinc. 
     
     
         9 . The fiber for artificial hair according to  claim 8 , wherein a content of the metal is 5.0×10 −5  to 5.0×10 −3 % by mass based on the total mass of the fiber for artificial hair. 
     
     
         10 . The fiber for artificial hair according to  claim 8 , further comprising an antistatic agent that is present in at least a part of the surface of the base fiber, wherein a content of the antistatic agent is 0.020 to 0.400% by mass based on the total mass of the fiber for artificial hair. 
     
     
         11 . The fiber for artificial hair according to  claim 8 , further comprising a silicone compound that is present in at least a part of the surface of the base fiber, wherein a content of the silicone compound is 0.010 to 0.300% by mass based on the total mass of the fiber for artificial hair. 
     
     
         12 . The fiber for artificial hair according to  claim 8 , wherein the base fiber contains a vinyl chloride-based resin. 
     
     
         13 . A headdress article comprising the fiber for artificial hair according to  claim 8 . 
     
     
         14 . The fiber for artificial hair according to  claim 1 , wherein the metal salt contains copper. 
     
     
         15 . The fiber for artificial hair according to  claim 14 , wherein a content of the metal is 5.0×10 −5  to 5.0×10 −3 % by mass based on the total mass of the fiber for artificial hair. 
     
     
         16 . The fiber for artificial hair according to  claim 14 , further comprising an antistatic agent that is present in at least a part of the surface of the base fiber, wherein a content of the antistatic agent is 0.020 to 0.400% by mass based on the total mass of the fiber for artificial hair. 
     
     
         17 . The fiber for artificial hair according to  claim 14 , further comprising a silicone compound that is present in at least a part of the surface of the base fiber, wherein a content of the silicone compound is 0.010 to 0.300% by mass based on the total mass of the fiber for artificial hair. 
     
     
         18 . The fiber for artificial hair according to  claim 14 , wherein the base fiber contains a vinyl chloride-based resin. 
     
     
         19 . A headdress article comprising the fiber for artificial hair according to  claim 14 .
