Zusammenfassung:	PURPOSE:The titled fiber having a melting point and a heat shrinkage factor in specific ranges, respectively, softness, high strength, improved adhesiveness and heat stability, consisting of a copolymer of a specific polyester component and polyalkylene glycol component. CONSTITUTION:A copolyester (100-160 deg.C melting point) consisting of 60-95wt% polyester component comprising a main dicarboxylic acid component having terephthalic acid and isophthalic acid in a molar ratio of 50-95:50-5 and ethylene glycol as a main alkylene glycol component and 5-40wt% polyalkylene glycol component (>=300mol.wt.) is used and it has
