Zusammenfassung:	By using common synthetic fiber as skeleton and through serial chemical reactions of semi-carbonization, sulfonation or amination, etc., specific ion groups are introduced into said synthetic fiber to prepare functional ion exchange fiber. The ion exchange fiber thus prepared has great specific surface area, great exchange capacity, fast exchange speed, short regeneration time, long service life,stable adsorption decoloring and other advantages; and may be used widely in environment protection, medical health care, petrochemical, metallurgical, water treatment, chemical adsorption, resource recovery and other fields.
