<p>A highly water-absorbent fiber made from a copolymer composed of: (a) comonomer units comprising a vinyl monomer having a carboxyl group, wherein the carboxyl groups of part of the units form sodium and/or potassium salts, and (b) comonomer units comprising monomers such as a vinyl monomer having an amino group and a vinyl monomer having both of hydroxyl and amino groups. The fiber is excellent in water absorbency, scarcely undergoes discoloration, is excellent in physiological saline absorbency, and can be produced under ordinary spinning conditions.</p> |
