The present invention provides cation exchange fibers having a high capacity of ion exchange and a high utilization rate of ion exchange radicals. The fibers are produced so as to have 3 m eq/g or more of carboxyl groups introduced by simultaneous crosslinking and hydrolyzing treatments of acrylic fibers, and to have tensile strength 1 g/d or more and a degree of water-swellability less than 100%, while maintaining fiber properties without problems in practical use.
