Problems solved by technology

However, fluff and yarn breakage caused by roll contamination, which had not been a problem until now, could not be improved even with the use of this treatment agent.
[0006] Therefore, it is desired to obtain a treatment agent that is excellent in heat resistance and can suppress the reduction in productivity due to the shortening of the cleaning interval of the roller and the increase in the number of cleanings.

[0195] The components described in Table 2 were mixed and stirred until uniform to prepare a treatment agent. Using each of the prepared treatment agents, the following methods were used to evaluate the accumulation of contamination on pins, the stain wiping properties of pins, and the variation in tension. The results are shown in Table 2.

[0196] In addition, the figure of the non-volatile component composition of the processing agent of Table 2 shows the weight ratio of each component in the non-volatile component of a processing agent. C-1 to C-5, D-1 and D-2 in Table 2 used the components shown below.

Abstract

Provided are: a synthetic-fiber treatment agent which is used in the production of a synthetic fiber, which can reduce roll staining, and which is excellent in heat resistance; a method for producing synthetic-fiber filament yarn using the treatment agent; and a fibrous structure including the synthetic-fiber filament yarn obtained by the production method. The synthetic-fiber treatment agent contains a smoothing component (A) and a nonionic surfactant component (B), wherein the component (A) includes an ester compound (A2) having a structure in which a fatty acid and a multivalent aliphatic alcohol form an ester bond, and the contained amount of metals (excluding alkali metals) detected in nonvolatile components of the treatment agent by ICP emission spectrometry is 50 ppm or less.

Description

technical field [0001] The present invention relates to a treatment agent for synthetic fibers and its application. More specifically, it relates to a treatment agent for synthetic fibers used when producing synthetic fibers, a method for producing a synthetic fiber filament yarn using the treatment agent, and a fiber structure including the synthetic fiber filament yarn. Background technique [0002] In the past, the fiber treated with fiber oil was temporarily crimped and then sent to the drawing process for treatment, but recently this process has been shortened, and the oiling (oiling) yarn is directly sent to the drawing process for treatment. . [0003] In this method, if a problem such as yarn breakage occurs in the stretching step, a large amount of fiber loss occurs, and therefore, it is necessary to avoid problems in the stretching step as much as possible. The main cause of the problem is fiber damage such as yarn breakage, and in order to prevent this problem, ...
