Abstract
Carbon fiber precursor treatment agents include a nonionic surfactant, an amino-modified silicone, and a dimethyl silicone with a kinematic viscosity at 25° C. of 5 to 200 mm/s. The mass ratio of the content of the amino-modified silicone with respect to the content of the dimethyl silicone is 99.9/0.1 to 90/10. Alternatively, when the total content of the nonionic surfactant, the amino-modified silicone, and the dimethyl silicone is taken as 100 parts by mass, the nonionic surfactant is contained at a ratio of 9 to 85 parts by mass, the amino-modified silicone is contained at a ratio of 10 to 90.9 parts by mass, and the dimethyl silicone is contained at a ratio of 0.1 to 5 parts by mass.
