PCT No. PCT/JP96/00729 Sec. 371 Date Sep. 12, 1996 Sec. 102(e) Date Sep. 12, 1996 PCT Filed Mar. 21, 1996 PCT Pub. No. WO96/30427 PCT Pub. Date Oct. 3, 1996The present invention relates to an elastic fiber of polyester elastomer mainly comprising the polyester elastomer further comprising aromatic polyester component as a hard segment and poly(alkyleneoxide)glycol having a number-average molecular weight of 500 to 5000 as a soft segment, wherein a residual elongation after 400 percent stretching does not exceed 100 percent. Made of the polyester elastomer comprising 1,2-bis[4-(2-hydroxyethyl)phenoxy]ethane as the diol component constituting said aromatic polyester component, or 1,4-benzenediethanol and ethyleneglycol as the diol component constituting said aromatic polyester component, the elastic fiber features excellent elastic properties in the event of great deformation and provides suitable material for clothing.
