摘要：
A process for producing a regenerated fiber by treating a regenerated collagen fiber with a monofunctional epoxy compound and a metallic aluminum salt characterized in that, in the treatment with the monofunctional epoxy compound, sodium hydroxide is added to such a level as giving a concentration of 0.001 to 0.8 N in the liquor to be treated and the treatment is initiated by adding an inorganic salt in such a level as to give the water absorption ratio of the regenerated collagen fiber product of 100% or lower depending on the amount of the sodium hydroxide added; and a process for setting the regenerated collagen fiber characterized by heat-setting the regenerated collagen fiber obtained by the above production process by a wet heat treatment at 50 to 160 DEG C and a dry treatment at 20 to 220 DEG C.
