摘要
Disclosed is a synthetic fiber treating agent for papermaking, which is capable of providing synthetic fibers for papermaking used for a paper-made nonwoven fabric with good dispersibility at low share, while suppressing the formation of air bubbles during a papermaking step. Consequently, the synthetic fiber treating agent for papermaking is capable of providing excellent fiber dispersibility. Specifically disclosed is a synthetic fiber treating agent for papermaking, which contains, as essential ingredients, a component A that is composed of a polyester compound obtained by polycondensing at least one dicarboxylic acid (derivative) selected from among aromatic dicarboxylic acids, aliphatic dicarboxylic acids having 4-22 carbon atoms and ester-forming derivatives thereof, and an alkylene glycol, a polyalkylene glycol or a derivative thereof, and a component B that is composed of a condensation product of a fatty acid and an alkanol amine.
