ABSTRACT:
The present invention provides a regenerated collagen fiber exhibiting a draping, luster and feel close to those of a natural protein fiber such as a human hair and capable of application of a permanent wave treatment, and a method of manufacturing the regenerated collagen fiber. The amino group and/or carboxyl group of the regenerated collagen is chemically modified to introduce a mercapto group and/or a disulfide linkage to the regenerated collagen. When subjected to a permanent wave treatment, the regenerated collagen fiber retains the waved shape.
