Description

The present invention relates to a doll or a zoomorphic toy and a method for manufacturing the same. More specifically, the present invention relates to a doll or a zoomorphic toy with curled hair and a method for manufacturing the same.

Conventionally, doll toys with curled hair pass the hair through two meshing gears that are adjusted by heating the doll hair with a heater, and the hair that is crimped according to the length of the gear pitch and the preheated hair are stored in one room. It is disclosed that the hair is folded and packed in a squeeze, the hair is crimped by moist heat, the hair is passed through a slit, and the hair is crimped by swirling of squeezed air (see, for example, Patent Document 1).
However, it is difficult to maintain the crimping property of the hair having the crimping property, and the doll toy planted on the head of the doll cannot maintain the curled state permanently and impairs the commercial value.

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.
If the blending amount is less than 0.5% by mass, it is difficult to visually recognize a clear thermal discoloration effect, and if it exceeds 40% by mass, it is excessive and may cause residual color in a decolorized state.
As the photochromic material, a photochromic compound such as a spirooxazine-based compound, a spiropyran-based compound, or a diarylethene-based compound is effective.

Furthermore, various general-purpose plasticizers such as phthalic acid-based, aliphatic dibasic acid ester-based, phosphoric acid ester-based, epoxy-based, phenol-based, and trimellitic acid-based are blended to impart flexibility and processing. Calcium carbonate, magnesium carbonate, titanium oxide, talc and the like can also be added in order to improve the properties, physical properties and the like.
