Definitions

  • the present invention relates to a hair bundle used for dolls or humans. More specifically, the present invention relates to a hair bundle that is mounted to dolls or human hairs such that various hairstyles can be achieved.
  • Hair products such as wigs and hair wigs that are attached to the hair of the head are known.
  • a hair product for example, there is a fiber for artificial hairs that is subjected to a forming process that deforms such as curls and waves etc. by heating (see, for example, patent document 1).
  • the forming process when performing the forming process, a heating equipment such as a hair iron etc. must be used, and the forming process takes time and effort accordingly. Further, when performing the forming process, it is necessary to heat the fiber for artificial hairs at a suitable temperature for it, and it may take time and effort to adjust the temperature. For example, if the heating temperature is too low, the forming process for the fiber for artificial hairs may be insufficient, so that the durability of curls, waves, etc. after the forming process may decrease. On the other hand, if the heating temperature is too high, the fiber for artificial hairs may be degenerated, so that the forming process for the fiber for artificial hairs may become impossible.

  • the core material 3 is preferably composed of the following materials from the point of view of the shape maintainability.
  • the constituent material of the core material 3 is not particularly limited, and for example, a thermoplastic resin satisfying the condition that the return angle by bending 90 degrees is preferably 15 degrees or less, more preferably 10 degrees or less can be used (see e.g. JP2003-278026A).
