Abstract:
The present invention addresses the problem of suitably suppressing fluffing during a spinning process. This method for producing a treatment agent for synthetic fibers, wherein the boron content in the nonvolatile content of the treatment agent for synthetic fibers as detected by ICP emission spectrometry is 200 ppm or less, comprises: an addition step wherein a (poly)oxyalkylene derivative is produced by adding an alkylene oxide to an alcohol in the presence of a catalyst that has a boron atom in each molecule; and a removal step wherein the catalyst is removed so that the boron content in the nonvolatile content of the treatment agent for synthetic fibers as detected by ICP emission spectrometry becomes 200 ppm or less.
