Abstract
An artificial hair fiber comprising a synthetic resin fiber; and one or more compounds selected from the group consisting of palmitic acid, a palmitate, palmitic acid glyceride, stearic acid, a stearate, and stearic acid glyceride, adhering to the synthetic resin fiber, wherein a total content of the compound is 0.05 wt % or more and less than 0.15 wt % based on a total amount of the artificial hair fiber.
Claims5
An artificial hair fiber comprising:
- a synthetic resin fiber having a fineness of between about 55 dtex and about 70 dtex;
- and
- one or more compounds selected from the group consisting of a palmitate and a stearate adhering to the synthetic resin fiber, wherein the palmitate is a sodium palmitate salt, and the stearate is a sodium stearate salt, wherein the synthetic resin fiber comprises a vinyl chloride resin, a polyethylene resin, or an ethylene alcohol (EVOH) resin, and wherein
- a total content of the compound is 0.05 wt % or more and less than 0.15 wt % based on a total amount of the artificial hair fiber.
1 more element
