  The present invention aims to provide a doll or animal figure toy capable of permanently maintaining the curled hair state and a method for producing the same, which solve the above-mentioned problems of toys with hair having crimps. Is.

The present invention comprises a hair made of a composite fiber on a doll or animal figure toy, and the composite fiber comprises a first resin and a second resin having a different chemical composition from the first resin, The center position of the second resin requires a doll or animal figure toy that is a composite fiber having crimpability shifted from the center position of the composite fiber.
Furthermore, the doll or animal figure toy consists of a first resin and a second resin having a different chemical composition from the first resin, and the center position of the second resin is from the center position of the composite fiber. There is a requirement for a method of manufacturing a doll or animal figure toy in which a composite fiber derived from a package wound with a composite fiber having shifted crimp properties is wound.

  The present invention relates to a doll or animal figure toy that can maintain the state of curled hair permanently and satisfies the merchantability, and a doll or animal figure that can maintain the state of curled hair permanently and satisfy the merchantability. An efficient manufacturing method of toys can be provided.

The hair implanted in the doll or animal figure toy of the present invention comprises a second resin having a different chemical composition from the first resin, and the center position of the second resin is shifted from the center position of the composite fiber. This is a composite fiber imparted with crimpability.
Examples of the cross-sectional shape of the composite fiber include a circle, an ellipse, and a regular polygon.
In the case of a shape in which the center position of the conjugate fiber and the second resin cannot be specified, it is possible to obtain a conjugate fiber imparted with crimpability by shifting the center of gravity of the second resin from the center of gravity of the conjugate fiber. it can.

The first resin and the second resin constituting the composite fiber are not particularly limited as long as they have different chemical compositions. Linear low density polyethylene, low density polyethylene, medium density polyethylene, ultra high density Polyethylene, chlorinated polyethylene, polypropylene, chlorinated polypropylene, polyisobutylene, polybutadiene, polymethylpentene, polystyrene, polyethylene terephthalate, polybutylene terephthalate, polyvinyl acetate, vinyl chloride resin, chlorinated polyvinyl chloride, polyvinylidene chloride, acrylic acid Ester resin, Methacrylate resin, Polyamide, Copolymer polyamide, Polyamideimide, Polyacetal, Polyvinyl formal, Polyvinyl butyral, Polyarylate, Polyetherimide, Polyetheretherketo , Polycarbonate, polyphenyl ether, polyphenylene sulfide, polysulfone, fluororesin, ionomer resin, polyolefin resin, ethylene-propylene copolymer resin, ethylene-vinyl acetate copolymer resin, ethylene-vinyl alcohol copolymer resin, ethylene-acrylic acid ester copolymer Polymerization resin, ethylene-methacrylate copolymer resin, ethylene-vinyl chloride copolymer resin, vinyl chloride-propylene copolymer resin, vinyl chloride-vinylidene chloride copolymer resin, styrene-butadiene copolymer resin, acrylonitrile-vinylidene chloride copolymer Resin, acrylonitrile-styrene copolymer resin, acrylonitrile-ethylene-styrene copolymer resin, acrylonitrile-butadiene-styrene copolymer resin, acrylonitrile-chlorinated polyester Lene-styrene copolymer resin, acrylonitrile-acrylic acid ester-styrene copolymer resin, ethylene-vinyl acetate resin-vinyl chloride graft copolymer resin, methyl methacrylate-butadiene-styrene copolymer resin, styrene thermoplastic elastomer, olefin Plastic elastomer, urethane plastic elastomer, polyester plastic elastomer, 1,2-polybutadiene plastic elastomer, vinyl chloride plastic elastomer, petroleum hydrocarbon resin, cellulose acetate, cellulose acetate propionate, cellulose acetate butyrate, nitrocellulose And low molecular weight polyethylene, low molecular weight polypropylene, polybutene, coumarone-indene copolymer, phenoxy plastic, and the like.
Among the resins, a polyamide resin and polybutylene terephthalate having excellent fiber forming properties are suitable as the first resin, and a polyolefin resin is suitably used as the second resin.
Examples of the polyamide resin include 6 nylon, 6,6 nylon, 6,9 nylon, 610 nylon, 11 nylon, 12 nylon, 6-11 copolymer nylon, 6-12 copolymer nylon, and 6,9-12 copolymer. Polymerized nylon and polyamide elastomer are preferably used, and as the polyolefin resin, linear low density polyethylene, polypropylene homopolymer, and polypropylene ethylene random copolymer are preferably used.

The composite fiber has a core-sheath type in which a second resin forms a core and the first resin is wound around and joined to the periphery, or the first resin and the second resin are joined in parallel. The fiber may be crimped by shifting the center position of the second resin from the center position of the composite fiber, and further crimped by heating. Improves.
A package is obtained by winding the composite fiber around a cylindrical body, and a doll or animal figure toy is obtained by flocking the composite fiber derived from the package.
The doll or animal figure toy can be warmed after planting to improve crimpability, and can be crimped by heating at a temperature higher than the heat set temperature after stretching at the time of spinning the composite fiber. Can be effectively expressed.

  The outer diameter of the composite fiber is in the range of 30 to 200 μm, more preferably 40 to 120 μm, and those having a diameter of less than 30 μm are too thin to be suitable as hair, whereas on the other hand, the outer diameter exceeds 200 μm. After that, it becomes difficult to show the properties of the hair.

General pigments, fluorescent pigments, reversible thermochromic materials, photochromic materials (photochromic materials) and the like can be added to the first resin and the second resin to obtain fibers exhibiting various colors.
The reversible thermochromic material includes a microcapsule containing a reversible thermochromic composition containing three components of an organic compound medium that reversibly causes a color reaction between an electron donating colorable organic compound and an electron accepting compound. Reversible thermochromic microcapsule pigments are effective.
The reversible thermochromic microcapsule pigment is contained in the resin in an amount of 0.5 to 40% by mass, preferably 1 to 30% by mass.
When the blending amount is less than 0.5% by mass, it is difficult to visually recognize a vivid thermochromic effect. When the blending amount exceeds 40% by mass, the amount is excessive and a decolored state may be generated.
Photochromic compounds such as spirooxazine compounds, spiropyran compounds, and diarylethene compounds are effective as the photochromic material.

  Furthermore, general-purpose plasticizers such as phthalic acid, aliphatic dibasic acid ester, phosphoric acid ester, epoxy, phenol, trimellitic acid, etc. In order to improve the properties and physical properties, calcium carbonate, magnesium carbonate, titanium oxide, talc and the like can be added.

The doll or animal figure toy and the manufacturing method thereof according to the present invention will be described more specifically with reference to examples. However, the present invention is not limited to the examples. In addition, the mixing | blending in an Example shows a mass part.
