ABSTRACT:
A process for producing a gel fiber comprises a step (N) of spinning a solution containing at least one polymer having at least one monomer unit as a constituent component for a gel to solidify the solution into a fiber, and step (M) of effecting crosslinking of the fiber to form a gel which can be swelled or shrunk reversibly by a thermal action in the presence of a liquid.
