2. Description of the Related Art Advances in synthetic fiber spinning technology have been remarkable, and particularly in recent years, with the development of high-speed winders, the spinning speed has been increasing. These technologies focus on the improvement of discharge productivity and the application development as a peculiar material resulting from the change in the fiber microstructure peculiar to the spinning process,
Various research and development are being promoted. However, as the spinning speed increases, abrasion between the traveling yarn and various yarn guides or abrasion between fibers within the traveling yarn bundle increases, which not only impairs the quality of the obtained yarn, but rather increases the production efficiency. It includes the problem of deterioration.

The fiber / metal dynamic friction coefficient of the oil agent is 0.35.
If it is less than the above, it is estimated that the gripping property between the contact pressing roller of the take-up raw yarn and the take-up winder becomes poor, and a defective winding shape such as a bulge on the end face of the package occurs, resulting in poor operability. It is not preferable because it causes deterioration and unwindability of the fiber in the post-processing step. On the other hand, when this friction coefficient exceeds 0.40, the friction between the running yarn and various yarn guides (rollers, guides, etc.) increases, and single yarn breakage and eventually yarn breakage are induced, resulting in the quality of the obtained yarn. It is not preferable because it damages.

When the fiber / fiber static friction force is less than 20.0 g, the package shape retention of the wound fiber becomes insufficient, resulting in deterioration of operability and unwinding property of the fiber. It is not preferable because it causes it. On the other hand, when it exceeds 25.0 g, the friction between the fibers in the running yarn bundle increases, and the single yarn breakage and eventually the yarn breakage are induced, which not only impairs the quality of the obtained yarn but also decreases the production efficiency. It is not preferable.

The composition of the oil agent used in the present invention is arbitrary as long as the above characteristics are satisfied. For example, a mono- or divalent aliphatic ester compound having a molecular weight of 450 to 500 is used as a main smoothing agent component, and an oil film is formed. As a strength improving component, a compound containing a small amount of a polyoxyalkylene glycol-based copolymer can be exemplified. Specifically, as the aliphatic ester compound, isocetyl palmitate, isotridecyl stearate, and diethylene glycol dilaurate are preferably used, and the polyoxyalkylene glycol copolymer has an average molecular weight of 4,000 to 7,000.
The tetramethylene oxide / ethylene oxide (weight ratio 30/70) block copolymer of is preferably used. At this time, the blending amount of the aliphatic ester is such that 50% by weight or more of the smoothing agent component in the oil agent is occupied by the aliphatic ester, and the proportion of all the smoothing agent ingredients in the oil agent is 50 to 70% by weight. %, On the other hand, the compounding amount of the above polyoxyalkylene copolymer is preferably such that the ratio of the compound in the oil agent is 0.5 to 2% by weight.

The above-described oil agent may be applied to the polyester fiber after the spun yarn is solidified, but is usually applied before the take-up roller.
As a preferable means for applying, there is a means for forming the above-mentioned oil agent in an aqueous emulsion and applying it through a metering oiling nozzle, but it is not limited to this. The applied amount is 0.2 to 1.
It is necessary to set the content to 0% by weight. By doing so, the yarn formability is improved and the winding shape of the package is improved. If the applied amount is less than 0.2% by weight, it will be difficult to suppress single yarn breakage even with the use of the above oil agent, and it will not be possible to stably produce homogeneous fibers. On the other hand, when it exceeds 1.0% by weight, an excessive amount of the oil agent is easily scattered, which not only deteriorates the working environment but is also not preferable in terms of the oil agent cost.

In the past, the defective winding form of the wound package is considered to be due to the large slippage between fibers and the inability to maintain the form, and increasing the static friction force between fibers is a means of improving the winding form. Was said to be. However, 30
At a spinning speed of 00 m / min or more, if the fiber / interfiber static friction force increases, single yarn breakage occurs frequently and only fluff is obtained, so the fiber / fiber static friction force cannot be sufficiently increased. There was a limit to the improvement of the package shape.

On the other hand, according to the present invention, when wound at a spinning speed of 3000 m / min or more, the winding shape of the package is not only the fiber / fiber static friction force of the oil agent but also the fiber / metal dynamic friction coefficient. But I found that it changed. The fiber / fiber static friction force is 20.0 to 25.
When an oil agent with 0 g and a dynamic frictional force between fiber and metal of 0.35 to 0.40 was simultaneously applied, the detailed reason has not yet been clarified, but the winding form is good without impairing the spinnability. It is possible to obtain various packages.

Example 1 Polyethylene terephthalate having an intrinsic viscosity [η] of 0.64 was melted and discharged to form a 36 filament yarn. After solidification of the yarn, 0.5% by weight of the oil agent shown in Table 1 was applied to the yarn weight through a metering oiling nozzle, and then it was taken out through a take-up roller having a surface speed of 3500 m / min. A drawn yarn of 75 denier / 36 filament was obtained by drawing 1.5 times between the take-up roller and the drawing roller. The results are shown in Table 1.
