2. Description of the Related Art Polyester ultrafine multifilaments having a single yarn fineness of 1.0 d or less are used in a wide range of applications such as natural leather-like fabrics and peach skin-like fabrics because of their excellent texture. Various methods are used as a method for producing such an ultrafine multifilament,
Japanese Patent Application Laid-Open No. Sho 54-30924 discloses a method of relatively simple production without using a special spinning apparatus.
A method has been proposed in which spinning is performed at a high speed of at least one minute to obtain highly oriented ultrafine fibers having a single yarn fineness of 1.0 d or less.

According to this method, the discharge amount per spinning hole formed in the spinneret is increased, the yarn sway downstream of the spinneret is reduced with an increase in spinning tension, and further, a high degree of orientation is achieved. There is an advantage that the fineness unevenness is reduced due to the effects such as above, and an ultrafine multifilament can be obtained relatively easily.

However, as the fineness of the single yarn becomes smaller and the number of filaments becomes larger, the air resistance acting on the spun yarn increases drastically, so that the spinning tension becomes too high to cause draft breakage or accompanying flow. This causes a problem that the occurrence of swelling increases, the sway of the yarn increases, the unevenness of the fineness of the yarn increases, and the uniformity deteriorates.

Therefore, conventionally, in the method of producing ultrafine fibers by high-speed spinning, the arrangement of discharge holes formed in the spinneret is devised, and the air resistance of the cooled yarn during running is suppressed as much as possible. A method of suppressing the spinning tension and a method of controlling the cooling rate of the yarn have been adopted. With these methods, it has become possible to produce ultrafine fibers having a single yarn fineness of about 0.5 d after spinning-off. However, when compared with a general yarn having a fineness of a single yarn of 2 to 3 d after spinning, the spinning,
There were many problems such as a high yarn breakage rate in the winding step, breakage of single yarn and slack yarn in the wound package, and poor uniformity of the obtained yarn.

[0006] An oil agent is applied to the melt-spun yarn in order to improve the bunching property and the passability of the subsequent process. In order to uniformly apply the oil agent, the oil agent is applied while being bundled by an oiling nozzle. After that, a method of further applying an oil agent with an oiling roller has been proposed (JP-A-61-19810).
issue). However, this method has a certain degree of effect on a fiber with a small influence of air resistance such that the single-fiber fineness exceeds 1 d, but has a certain effect on an ultra-fine multifilament with a single-fiber fineness of 1 d or less. The air resistance increases, and the spinning tension increases, so the oil film is more susceptible to oil film resistance when the oil is applied, spun yarns and single yarns are more likely to occur, and spots occur, resulting in poor quality after processing and dyeing. There's a problem.

In this method, two or more yarns are obtained from individual spinnerets. In other words, this is a method in which the ejection holes formed in the spinneret are divided into multi-block groups, and a number of yarns corresponding to each block group are collected and wound.

When the concentration of the oil agent is less than 5% by weight or the amount of the oil agent component adhered to the entire yarn is less than 0.6% by weight, the oil agent is not sufficiently applied to the yarn, so that the bunching property is deteriorated. In the process, single yarn breakage occurs frequently due to abrasion, and slack yarn is mixed in the package. On the other hand, when the concentration of the oil agent exceeds 18% by weight, the dispersibility in the solvent is reduced, and it is difficult to uniformly adhere the yarn to the yarn.
Thread breakage occurs frequently in subsequent processes. On the other hand, if the amount of the oil component adhered to the entire yarn exceeds 1.4% by weight, the amount of the oil agent component will be too large, and smoke and heater contamination will be caused in the subsequent process, and the environment will be deteriorated.

As a result, the bundle convergence of the yarn was deteriorated, the yarn was frequently broken, the slack yarn was mixed in the package, and the package defect ratio was increased. In Comparative Example 2, since the concentration of the oil applied by the oiling nozzle (A) was too high, in Comparative Example 6, the concentration of the oil applied by the oiling roller (B) was too high, and the spinning tension was increased by the oil film resistance. ,
Thread breakage occurred, sagging yarn was mixed in the package, and unevenness of fineness occurred in the resulting fiber. In Comparative Example 10, when the concentration of the oil agent applied by the oiling roller (C) was set to 20% by weight, the oil agent could not be uniformly dispersed, and the operation was impossible. In Comparative Example 3, the amount of the oil applied by the oiling nozzle (A) was too low, and in Comparative Example 7, the amount of the oil applied by the oiling roller (B) was too low. Since the amount of the oil agent applied by the oiling roller (C) was too low, the convergence of the yarn deteriorated, single yarn breakage due to rubbing frequently occurred in the subsequent process, and the slack yarn was mixed in the package. In Comparative Examples 3 and 7, unevenness in fineness occurred in the obtained fibers. In Comparative Example 4, the amount of the oil applied by the oiling nozzle (A) was too high, and in Comparative Example 8, the amount of the oil applied by the oiling roller (B) was too high.
