Abstract (en)
[origin: EP3656897A1] This diluted solution of a synthetic fiber treatment agent contains: a synthetic fiber treatment agent containing a smoothing agent, a non-ionic surfactant, and an antistatic agent; and a volatile diluent. When the total of the proportions of the synthetic fiber treatment agent and the volatile diluent in the diluted solution is defined as 100% by mass, the proportion of the synthetic fiber treatment agent is equal to or greater than 60% by mass and less than 100% by mass, and the proportion of the volatile diluent is greater than 0% by mass and less than or equal to 40% by mass, the kinematic viscosity of the diluted solution at 30°C being greater than 0 mm<sup>2</sup>/s and less than 80 mm<sup>2</sup>/s, and the diluted solution being applicable to a prescribed spinning/stretching step in which there is used a spinning/stretching machine comprising a plurality of heating rollers for stretching a spun yarn.
