摘要： Disclosed is an elastic fiber treatment agent that contains a smoothing agent and an alkyl phosphate ester compound. The alkyl phosphate ester compound contains specific phosphate ester Q1 and at least one or more selected from specific phosphate esters Q2 and Q3. In a P nucleus NMR measurement of the alkyl phosphate ester compound upon an alkali over-neutralization pretreatment, a P nucleus NMR integral ratio attributed to the phosphate ester Q1 is 15% to 60% if the sum of P nucleus NMR integral ratios attributed to the phosphate esters Q1 to Q3 and phosphoric acid and its salt is taken as 100%.

摘要： 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 mm2/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.

摘要： 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.

摘要： Disclosed is a carbon fiber precursor treatment agent that contains a specific (poly)oxyalkylene derivative and a smoothing agent. The smoothing agent contains at least one selected from the group consisting of an amino-modified silicone, a polyether-modified silicone, a dimethyl silicone, and an ester compound. Assuming that the sum of the content ratios of the (poly)oxyalkylene derivative and the smoothing agent in the carbon fiber precursor treatment agent is 100% by mass, the carbon fiber precursor treatment agent contains the (poly)oxyalkylene derivative at a ratio of 5% by mass or more and 80% by mass or less and the smoothing agent at a ratio of 20% by mass or more and 95% by mass or less.
