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.
