Disclosed is a synthetic fiber treatment agent containing a phenol amine compound and a nonionic surfactant. The phenol amine compound is at least one selected from the group consisting of a compound formed from a phenol derivative, formaldehyde, and a polyamine compound and a compound obtained by reacting a boron-containing compound with a compound formed from a phenol derivative, formaldehyde, and a polyamine compound. The phenol derivative is a phenol in which a hydrocarbon group with a number average molecular weight of not less than 100 and not more than 2000 is modified.

Synthetic fiber processing agent and synthetic fiber

An inorganic fiber sizing agent that contains at least one carbon nanostructure selected from the group consisting of carbon nanotubes and carbon nanofibers, a resin, and a surfactant. If the total content of a nonvolatile content of the resin and the surfactant is taken as 100 parts by mass, the inorganic fiber sizing agent contains the surfactant at a ratio of 2 to 50 parts by mass.
