Japanese Patent JP7033585
Kind Code:
B2
Abstract:
The present invention, in one embodiment, relates to core-sheath conjugate fibers for artificial hair comprising a core part and a sheath part. The fibers have a core-to-sheath area ratio of core:sheath = 2:8 to 7:3, an eccentricity of 5% or more, and a flat multilobed shape in cross section. In the fiber cross section, a ratio of a length of a major axis of the fiber cross section to a length of a first minor axis of the fiber cross section is 1.10 or more and 3.00 or less, and a ratio of a length of a major axis of the core part to a length of a first minor axis of the core part is 1.10 or more and 3.00 or less. A direction of the major axis of the fiber cross section and a direction of the major axis of the core part substantially coincide with each other. The present invention further relates to hair ornament products comprising the core-sheath conjugate fibers for artificial hair. Thus, the present invention provides core-sheath conjugate fibers for artificial hair having touch and appearance close to human hair, exhibiting favorable curling property without the need for curl setting and having extremely high curl retentive property, and hair ornament products including the same.
