There is. In the case of a so-called water-free straight type oil, the viscosity is high and the wetness of the running yarn becomes poor, so that the resulting polyester fiber yarn is liable to generate fluff or to be liable to be oiled. It is not preferable because the load on the running yarn is excessively applied and the single-weave is easily broken.

It was found that they could do it.
• a method of adding a high polymer of hardened castor oil or a polyhydric alcohol polyester has been proposed.
• the method can provide a certain degree of effect, it is necessary to use a large amount of it in order to obtain the effect required for high-speed spinning. As a result, the simple friction of the fiber is reduced, and the winding form of the raw yarn wound at high speed becomes unstable, resulting in problems such as reduced operability and poor unwinding property of the raw yarn in the post-processing step. Is caused.

If the content is less than 1% by weight, the effect of improving the oil film strength is insufficient, while if it exceeds 15% by weight, the dynamic friction coefficient of the running yarn increases due to an increase in the viscosity of the oil agent. It is not preferable because fluff is likely to occur, and the coefficient of static friction is reduced to the contrary, and the appearance of the package is easily deteriorated.

• the upper limit of the average molecular weight of the polyoxyalkylene glycol copolymer is not particularly limited, but if it is too large, the viscosity of the oil agent increases and the dynamic friction of the high-speed running yarn is increased. In some cases, the stability of the oil agent emulsion is reduced, and the oil agent emulsion is likely to be deposited as scum. Therefore, it is preferable to select an appropriate average molecular weight according to the type of the polyoxyalkylene glycol copolymer used. New
