    摘要: An elastic fiber which is made of a polyether ester elastomer comprising polybutylene terephthalate as the hard segment and polyoxyethylene glycol as the soft segment and containing a specific metal organosulfonate in a state copolymerized therewith and exhibits a moisture absorption of 5% or above at 35°C and 95%RH and an elongation on water absorption of 10 % or above. Since the elastic fiber is excellent in moisture absorption characteristics and stretches and shrinks remarkably and reversibly in accordance with the absorption and desorption of water, comfortable fabrics can be made of the elastic fiber. Further, the elastic fiber is recyclable.
