Disclosed is a fiber treatment agent containing a component (a) and a component (b) and/or a component (c) as essential ingredients. The component (a) is a polyester compound obtained by polycondensing an alkylene glycol, a polyalkylene glycol and at least one dicarboxylic acid (derivative) selected from aromatic dicarboxylic acids, aliphatic dicarboxylic acids having 4-22 carbon atoms and ester-forming derivatives of those acids. The component (b) is an ester obtained by blocking, with a fatty acid, at least one hydroxyl group of a condensation product of a polyoxyalkylene group-containing hydroxyfatty acid polyhydric alcohol ester and a dicarboxylic acid. The component (c) is a dialkylsulfosuccinate ester salt wherein an alkyl group has 6-18 carbon atoms. The ratio of the component (a) in the nonvolatile component of the fiber treatment agent is 30-90% by weight, while the ratio of the total of the component (b) and the component (c) is 5-60% by weight. |
