Abstract (en)
The present invention addresses the problem of providing: an aqueous solution of a synthetic fiber treatment agent that has excellent low-temperature handling properties and can impart quality stability; and synthetic fibers having said synthetic fiber treatment agent adhered thereto and having excellent quality stability. 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 a specific ester A2, and the mass ratio of the content of the ester A1 with respect to the content of the ester A2 being ester A1/ester A2 = 3.0-9.0.
