摘要： The present invention addresses the problem of improving friction characteristics, when wet, of fibers to which a treatment agent for short fibers is adhered, and improving the heat resistance of the treatment agent for short fibers. This treatment agent for short fibers does not substantially include a phosphate compound, but does contain the fatty acid (A) below and a non-ionic surfactant. The fatty acid (A) is at least one fatty acid selected from C1-6 fatty acids, C1-6 hydroxy fatty acids, and salts of the aforementioned fatty acids.

摘要： The present invention addresses the problem of improving friction characteristics, when wet, of fibers to which a treatment agent for fibers is adhered. The treatment agent for fibers contains the fatty acid (A) below, an organic phosphate compound (B), and a (poly)oxyalkylene derivative (C). The fatty acid (A) is at least one fatty acid selected from C1-6 fatty acids, C1-6 hydroxy fatty acids, and salts of the aforementioned fatty acids.

摘要： Disclosed is a first agent-containing composition for treating synthetic fiber that is combined in use with a second agent for treating synthetic fiber containing a specific nonionic surfactant. The first agent-containing composition contains a first agent for treating synthetic fiber and a solvent. The first agent contains specific organic phosphoric acid ester salts at specific ratios and has a specific acid value. The solvent has a boiling point at atmospheric pressure of not more than 105° C. Assuming that the sum of the amounts of the first agent and the solvent contained in the first agent-containing composition is 100 parts by mass, the amount of the first agent contained in the first agent-containing composition is not less than 35 parts by mass and not more than 55 parts by mass.
