Abstract

The present invention addresses the problem of providing: a treatment agent for synthetic fibers, said treatment agent enabling synthetic fibers to achieve good spinnability with excellent fluffing resistance, while enabling synthetic fibers to achieve good adhesion to a rubber when used as a reinforcement cord; and synthetic fibers to which this treatment agent for synthetic fibers adheres. The present invention provides, as a means of solving the problem, a treatment agent for synthetic fibers containing from 30% by mass to 70% by mass of a smoothing agent, from 20% by mass to 60% by mass ofa nonionic surfactant and from 0.1% by mass to 10% by mass of an ionic surfactant if the total content of the smoothing agent, the nonionic surfactant and the ionic surfactant is taken as 100% by mass, said treatment agent being characterized in that: the smoothing agent contains a specific ester A and a specific ester B; the nonionic surfactant contains a specific polyoxyalkylene derivative C; and the ionic surfactant contains a specific organic phosphorus compound D.

Description

technical field [0001] The present invention relates to a processing agent for synthetic fibers and synthetic fibers. In detail, it relates to a processing agent for synthetic fibers that exhibits good process passability in the spinning process of synthetic fibers and has good rubber adhesion in the post-treatment process, and a synthetic fiber that adheres to the above-mentioned processing agent for synthetic fibers. fiber. Background technique [0002] In recent years, in the spinning process and processing process of synthetic fibers, the speed has been increased, and along with this, fuzz and end breakage have become more likely to occur. Therefore, as a treatment agent for synthetic fibers that inhibits them, a substance containing a polyether obtained by adding a polyoxyalkylene group to a polyhydric alcohol (for example, Patent Documents 1 and 2) or an organic compound having a specific structure has been proposed. Substances of zinc compounds (for example, Patent ...
