Zusammenfassung:	To provide a modified polyester composition, though having small fineness, capable of being colored by a cationic dye and having high strength as a fiber material, a fiber made thereof, and a fiber structure.SOLUTION: The present invention relates to a modified polyester composition, a fiber made thereof, and a fiber structure. The composition is a copolyester, in which a main repeating unit is alkylene terephthalate, and which contains isophthalic acid containing a predetermined amount of a metal sulfonate group in total dicarboxylic acid components; and includes, based on the total mass of the copolyester, a predetermined amount of an organic ionic compound expressed by the following general formula (I): RSO3X (I) (in the formula (I), R is an alkyl group of 1-30C or an aryl group of 7-40C and X is an alkali metal, etc.).SELECTED DRAWING: None 【課題】本発明の目的は、細繊度でありながらカチオン染料に染色可能で、繊維素材として高い強度を有する改質ポリエステル組成物とそれよりなる繊維および繊維構造体を提供することにある。【解決手段】本発明は、主たる繰り返し単位がアルキレンテレフタレートであり、全ジカルボン酸成分中に所定量の金属スルホネート基含有イソフタル酸を含有する共重合ポリエステルであって、該共重合ポリエステルの全質量を基準として、下記一般式（Ｉ）ＲＳＯ３Ｘ（Ｉ）（上記式（Ｉ）中、Ｒは炭素原子数１～３０のアルキル基または炭素原子数７～４０のアリール基、Ｘはアルカリ金属などを示す。）で示される有機イオン性化合物を所定量含有する改質ポリエステル組成物それよりなる繊維および繊維構造体である。【選択図】なし
