Abstract

Provided is artificial hair including chemical fibers and a fiber treatment composition that is adhered to the surfaces of the chemical fibers. The fiber treatment composition may include an oxazoline group-containing acrylic resin and an organic-modified silicone oil. The oxazoline group-containing acrylic resin may have a main chain that includes a (meth)acrylic acid ester and styrene.

First claim

The invention claimed is:

1. Artificial hair, comprising:
chemical fibers; and
a fiber treatment composition that is adhered to the surfaces of the chemical fibers,
wherein
the fiber treatment composition comprises an oxazoline group-containing acrylic resin and an organic-modified silicone oil, and
the oxazoline group-containing acrylic resin has a main chain comprising a (meth)acrylic acid ester and styrene,
the oxazoline group-containing acrylic resin contains the styrene in an amount of 27 to 55% by weight, contains the (meth)acrylic acid ester in an amount of 25 to 57% by weight, contains the (meth)acrylic acid ester and the styrene in a total amount of 80 to 84% by weight, and contains an oxazoline group-containing component in an amount of 16 to 20% by weight, and
the fiber treatment composition further comprises a copolymer of ethylene oxide and propylene oxide.

2. The artificial hair according to claim 1 , wherein the chemical fibers comprise one or more selected from the group consisting of polyvinyl chloride fibers, acrylic fibers, and polyester fibers.

3. The artificial hair according to claim 1 , wherein the organic-modified silicone oil comprises one or more selected from the group consisting of an amino-modified silicone oil and an epoxy-modified silicone oil.

4. The artificial hair according to claim 1 , wherein the fiber treatment composition further comprises a quaternary ammonium salt.

5. The artificial hair according to claim 1 , wherein the artificial hair contains the fiber treatment composition in an amount of 0.05 to 0.35% by weight on a solid basis.

6. The artificial hair according to claim 1 , wherein the artificial hair contains the oxazoline group-containing acrylic resin in an amount of 0.02 to 0.2% by weight.

7. The artificial hair according to claim 1 , wherein the artificial hair contains the organic-modified silicone oil in an amount of 0.03 to 0.3% by weight on a nonvolatile basis.

8. A hair ornament comprising the artificial hair according to claim 1 .

9. A method for producing artificial hair that comprises chemical fibers, comprising:
adhering a fiber treatment composition to the surfaces of the chemical fibers,
wherein the fiber treatment composition comprises an oxazoline group-containing acrylic resin and an organic-modified silicone oil, and
the oxazoline group-containing acrylic resin has a main chain comprising a (meth)acrylic acid ester and styrene,
the oxazoline group-containing acrylic resin contains the styrene in an amount of 27 to 55% by weight, contains the (meth)acrylic acid ester in an amount of 25 to 57% by weight, contains the (meth)acrylic acid ester and the styrene in a total amount of 80 to 84% by weight, and contains an oxazoline group-containing component in an amount of 16 to 20% by weight, and
the fiber treatment composition further comprises a copolymer of ethylene oxide and propylene oxide.

10. The artificial hair according to claim 1 , wherein the chemical fibers comprise polyvinyl chloride fibers, and wherein the polyvinyl chloride fibers contain the fiber treatment composition in an amount of 0.05 to 0.35% by weight on a solid basis.

11. The hair ornament according to claim 8 , wherein the chemical fibers comprise polyvinyl chloride fibers, and wherein the polyvinyl chloride fibers contain the fiber treatment composition in an amount of 0.05 to 0.35% by weight on a solid basis.

12. The method according to claim 9 , wherein the chemical fibers comprise polyvinyl chloride fibers, and wherein the polyvinyl chloride fibers contain the fiber treatment composition in an amount of 0.05 to 0.35% by weight on a solid basis.
