Abstract
Official abstract text for this publication.
A fiber for artificial hair that has an improved appearance with a suppressed gloss is obtained by combining regenerated collagen fibers having different shapes in cross section. An artificial hair product using the same is provided. The fiber for artificial hair according to the present invention is obtained by combining fibers having different shapes in cross section. The fiber for artificial hair includes regenerated collagen fibers, and the regenerated collagens fibers include at least two types of regenerated collagen fibers whose cross-sectional shapes are selected from the group consisting of shapes including an elliptical shape, a circular shape, and a multifoil shape. The artificial hair product of the present invention includes the above-described fiber for artificial hair.
First claim
Opening claim text (preview).
The invention claimed is: 1. Fibers for artificial hair obtained by combining fibers having different shapes in cross section, wherein the fibers for artificial hair comprise regenerated collagen fibers, and the regenerated collagen fibers include at least two types of regenerated collagen fibers whose cross-sectional shapes are selected from the group consisting of shapes including an elliptical shape, a circular shape, and a multifoil shape, wherein 1 to 49 mass % of the regenerated collagen fibers having an elliptical shape in cross section are combined. 2. Fibers for artificial hair obtained by combining fibers having different shapes in cross section, wherein the fibers for artificial hair comprise regenerated collagen fibers, and the regenerated collagen fibers include at least two types of regenerated collagen fibers whose cross-sectional shapes are selected from the group consisting of shapes including an elliptical shape, a circular shape, and a multifoil shape, wherein the fibers for artificial hair comprise only the regenerated collagen fibers, wherein 20 to 45 mass % of the regenerated collagen fibers having an elliptical shape in cross section are combined. 3. Fibers for artificial hair obtained by combining fibers having different shapes in cross section, wherein the fibers for artificial hair comprise regenerated collagen fibers, and the regenerated collagen fibers include at least two types of regenerated collagen fibers whose cross-sectional shapes are selected from the group consisting of shapes including an elliptical shape, a circular shape, and a multifoil shape, wherein 50 to 100 mass % inclusive of the regenerated collagen fibers are combined with 0 to 50 mass % inclusive of other fibers, wherein 1 to 49 mass % of the regenerated collagen fibers having an elliptical shape in cross section are combined.
