  • Fiber for artificial hair and artificial hair product using the same
    Patent number: 9637841
    Abstract: 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.

  • Process for producing regenerated collagen fiber
    Patent number: 5344917
    Abstract: A process for producing regenerated collagen fiber from solubilized collagen including adjusting a degree of swelling of solubilized collagen to 100 to 300% and then treating the resulting solubilized collagen with an aqueous solution of a metallic salt. The regenerated collagen fiber has excellent water resistance and undergoes no waving on contact with water.
