  • Examples 1 and 2 used covering yarn in which the outer circumference of the heat-sealed yarn was covered with a covering material. From this, it was confirmed that by covering the outer circumference of the heat-sealed yarn with a covering material, as in Examples 1 and 2, the texture (feel to the skin) was improved.
  • Example 1 was rated “4”
  • Examples 2 and 3 were rated “3”
  • Example 4 was rated “2.”
  • Example 1 was rated “4”
  • Examples 2 and 3 were rated “3”

  • heat-sealed yarn is used for the covering material rather than the core material, as in Examples 3 and 4, molding can be easily carried out without heat being transferred to the center of the core material.
  • Experiment 2 The applicant of the present invention conducted an experiment (hereinafter referred to as "Experiment 2") to confirm molding using heated water.
  • the outline and results of Experiment 2 are as follows.
  • a wig base was made using double covering yarn with 100 denier flor as the core material and 70 denier nylon as the covering material, and the wig base was placed on a head model (in experiment 2, a substitute head model was used instead of one created by a 3D printer), and the wig base was immersed in hot water at a temperature of 80°C (water temperature) and heated. The immersion time was 20 minutes. After immersion, the wig base was removed from the head model to check whether it maintained its shape.
  • the present invention can be particularly suitably used as a wig base 10 for the entire head, a wig 30 for the entire head, and a method for manufacturing a wig base 10 for the entire head.
