Zusammenfassung:	To provide a polyester fiber excellent in dyeability and fastness to light.SOLUTION: A polyester fiber is configured of polyester resin, where the polyester resin is a copolymer composed of a dicarboxylic acid component and a glycol component. Of the glycol component, 95-99.87 mol% is ethylene glycol and/or an ester-forming derivative thereof and 0.13-5 mol% is 1,2-propanediol and/or an ester-forming derivative thereof.SELECTED DRAWING: None 【課題】染色性及び耐光堅牢性に優れたポリエステル繊維を提供する。【解決手段】ポリエステル樹脂から構成されるポリエステル繊維であって、該ポリエステル樹脂がジカルボン酸成分とグリコール成分からなる共重合体であり、該グリコール成分のうち９５～９９．８７モル％がエチレングリコール及び／又はそのエステル形成性誘導体であり、０．１３～５モル％が１，２－プロパンジオール及び／又はそのエステル形成性誘導体であることを特徴とする、ポリエステル繊維。【選択図】なし
