Core-sheath conjugate fiber for artificial hair, hair ornament including same, and method for producing same

Abstract

One or more embodiments of the present invention relate to a core-sheath conjugate fiber for artificial hair including a core and a sheath. The core is composed of a polyester-based resin composition containing a polyester-based resin as a main component, and the sheath is composed of a polyamide-based resin composition containing a polyamide-based resin as a main component. A core-to-sheath area ratio of the core to the sheath is 2:8 to 7:3, and both a fiber cross-section and a core cross-section have a flat shape, a major axis of the core cross-section is in a direction that substantially coincides with a direction of a major axis of the fiber cross-section, and an eccentricity ratio of the fiber in a minor axis direction is 5% or more. As a result, fibers for artificial hair having a texture and an appearance that are similar to those of human hair and having favorable curl setting properties are provided.
