Abstract

PURPOSE: To obtain the title fibers having improved hygroscopicity, with little damage to the skin, free from yellowing, by introducing acidic groups(A) substituted with an alkali metal into the inner layers, and unsubstituted A into the outermost layers.
CONSTITUTION: Acidic groups in a vinyl monomer grafted onto polyamide fibers are substituted by an alkali metal in treatment with an aqueous alkali. The treated fibers are then neutralized with a weakly basic salt of a strong acid to give the desired fibers comprising the outermost (sheath) layers solely, rich in the acidic groups unsubstitued by the alkali metal and the inner (core) layers rich in the acidic groups substituted by the alkali metal.
