PROBLEM TO BE SOLVED: To provide a fiber that has extremely superior color fastness and also high durable hydrophilicity, to provide a fiber molding such as a nonwoven fabric, composed of the fiber, and to provide an absorbent article using the fiber or the fiber molding.SOLUTION: A fiber contains at least one thermoplastic resin and a fiber treating agent adhered thereon. The fiber treating agent contains 25 mass% or more of the following component (A), 5 mass% or more of the component (B) and 5 mass% or more of the component (C) based on an active substance, and is adhered on the fiber in an amount of 0.1-1.0 mass% based on a fiber mass. The component (A) is a sulfate salt having a 8-22C hydrocarbon group, the component (B) is a salt of sulfosuccinate diester having a 12-20C hydrocarbon group, and the component (C) is a phosphoric ester salt having a 4-18C hydrocarbon group. The fiber molding mainly composed of the fiber and the absorbent article obtained by using the fiber molding are also provided.COPYRIGHT: (C)2013,JPO&INPIT【課題】耐変色性が極めて優れており、かつ高い耐久親水性を持った繊維及びそのような繊維で構成された繊維成形体、例えば不織布を提供し、さらにそのような繊維または繊維成形体を用いた吸収性物品を提供する。【解決手段】少なくとも1種の熱可塑性樹脂を含み、繊維処理剤が付着している繊維であって、該繊維処理剤が有効成分基準で下記成分(A)を25質量%以上、成分(B)を5質量%以上及び成分(C)を5質量%以上含んでおり、該繊維処理剤が、繊維質量に対して0.1~1.0質量%付着している繊維による。成分(A):炭素数が8~22の炭化水素基を有する硫酸エステル塩;成分(B):炭素数が12~20の炭化水素基を有するスルホコハク酸ジエステル塩;成分(C):炭素数が4~18の炭化水素基を有する燐酸エステル塩。上記繊維を主体として構成されている繊維成形体、及び上記繊維成形体を用いて得られる吸収性物品。【選択図】なし
