Abstract (en)
[origin: EP4159913A1] The present invention addresses the problem of providing an aqueous solution of a synthetic fiber treatment agent that has excellent ingredient retention properties on fibers and that has excellent low-temperature handling properties. The present invention is an aqueous solution of a synthetic fiber treatment agent comprising a smoothing agent, a nonionic surfactant and an ionic surfactant, and is characterized by: the smoothing agent comprising a specific ester A1 and optionally a specific ester A2; the smoothing agent containing a ratio of 40-100 mass% of the ester A1; the ester A1 making up a ratio of 50-100 mass% when the total content ratio of the ester A1 and the ester A2 is 100 mass%; and the viscosity of the synthetic fiber treatment agent at 30°C being 40-150mm<sup>2</sup>/s.
