Definitions

  • the present invention is for a synthetic fiber that can sufficiently prevent oil drop in a spinning drawing method in which the number of yarns wound around a heating roller is small, has good spinnability, and can improve the yarn quality and dyeability of the obtained yarn.

  • Patent Document 1 uses a diluent for a synthetic fiber treatment agent having a high water content in a synthetic fiber spinning process, that is, a diluent for a synthetic fiber treatment agent having a low concentration of the synthetic fiber treatment agent. For this reason, when the yarn is heated to a predetermined temperature by the heating roller, a large amount of heat is consumed to evaporate the moisture in the diluted solution, and thus the heat efficiency is poor. Thereby, it is easy to induce spots of heat history during yarn drawing, and there is a problem in dyeability of the yarn. Further, when the contact length of the yarn with the heating roller is increased, heat is sufficiently transmitted to the yarn, and the problem of dyeability due to unevenness of the heat history is improved. However, the yarn has to be wound around a single heating roller many times, and the heating roller has to be lengthened in the axial direction.
  • the diluted solution of the treating agent for synthetic fibers used in Patent Document 2 has a problem that, as in Patent Document 1, sufficient dyeability of the yarn cannot be obtained because the thermal efficiency when heating the yarn is not high. It was. Therefore, it was necessary to increase the number of heating rollers or increase the outer shape of the heating roller in order to increase the contact length of the yarn to the heating roller. On the other hand, when the treatment agent for synthetic fibers in the diluted solution is used at a higher concentration, the kinematic viscosity is further increased, so that an oil drop occurs and the yarn quality also deteriorates.
  • the problem to be solved by the present invention is that, in a spinning drawing method in which the number of times of winding a yarn around a heating roller is small, oil drop can be sufficiently prevented, the spinning property is good, and the yarn quality and dyeability of the obtained yarn.
