In order to increase productivity, the spinning speed is increased by making the lk bath flow in the same direction as the running direction of the discharged yarn, reducing the coagulation bath resistance and preventing the decrease in strength and elongation of the yarn. Many spinning methods have been proposed. For example,
No. 7-132128 and Japanese Patent Application No. 57-158061 propose a level that allows industrial production.

However, as processing @ looms become more innovative, faster, diversified in the temporary goods market, and become more sophisticated, the industrial specifications required for raw yarn are also changing rapidly and are increasing day by day. It's getting tougher.

In particular, it is essential when considering the upgrading and high functionality of products.
Regarding the multiplication and fine denier of filaments, if the speed of the conventionally proposed quagmire spinning method is increased to increase productivity, process defects such as fuzz generation and cut yarn generation will increase, and the quality of the raw yarn will deteriorate. The rate of increase or decrease is incomparably thicker than that of ordinary yarn, and is ultimately insufficient for industrial production.

That is, the present invention provides a viscose rayon bog spinning method in which a coagulation bath is fluidly supplied to viscose at the time of discharge.

The present invention achieves the following two points that could not be achieved with the conventional viscose rayon bog spinning method by using a spinneret in which all discharge holes are arranged on one circumference. It provides a method to improve and solve problems.

Conventionally, in spinnerets for viscose rayon, in order to prevent the viscose discharged from the discharge holes from coming into contact with each other, the shortest distance between the discharge holes is usually set at 1M or more, or even in special cases. It is a well-known fact for those skilled in the art to provide 0.7W or more. Therefore, in order to make the distance between the discharge holes as large as possible, the discharge holes are distributed on multiple concentric circles and It is common knowledge that in the static bath spinning method where the coagulation bath is not intentionally supplied in a flowing direction in the direction of yarn movement, the discharge hole is Industrial production has been carried out using spinnerets dispersed and arranged in multiple layers, and no problems have arisen.

However, in the quagmire spinning method, the problem characteristically occurs when the discharge hole is half clogged, even though the discharge hole is not clogged with foreign matter or the like.

A problem arises in that large fluffs similar to so-called spinning fluffs in which the tip of the fluffs is obviously thicker than the single yarn diameter of the normal portion occur, reducing the process yield. Above all,
This generation of large fuzz is noticeable in multi yarns with a large number of single yarns and in muddy spinning with a fine denier.Furthermore, even when the spinning speed is increased by increasing the flow rate of the coagulation bath, the large fuzz generation rate also increases. This has become a major factor limiting industrial production and has not yet been resolved.

In order to solve this problem, the present inventors made the spun part transparent so that it could be observed externally, and as a result of the observation, it was found that the viscose was cut immediately after being discharged from the discharge hole of the spinneret. It was found that large fuzz was generated from all the inner layers except for the outermost layer of the multi-layered discharge holes, and the more the speed of the coagulation bath was increased, the more
It has been found that this phenomenon is becoming more prominent and frequent.

That is, in a spinneret with multiple array perforations, the flow vector of the coagulation bath applied to the single fibers in the inner layer is disturbed and constitutes a vortex as the flow velocity increases, and the total number of single fibers increases. The more the mulch increases, the more the accompanying flow increases, causing turbulence and further turbulence.As a result, single filaments that have just begun to coagulate and regenerate, especially single filaments with fine denier, are caught in the turbulence and cut. This is thought to be due to the formation of large fluff.

On the other hand, in the spinneret according to the present invention, in which all the discharge holes are arranged so that they are arranged on one circumference, all the single yarns have the same amount of tension. There are virtually no single filaments trapped in the area that receives and makes up the production line, and all flow vectors affecting the single filaments, including the accompanying flow, are concentrated at one point, so the coagulation bath Even if the accompaniment flow is increased by increasing the speed or multiplication, all these flows act in the direction of fixing the position of the single yarn without causing any sway.

In other words, as the speed of the coagulation bath increases, the tension applied to the single threads increases, and the threads become less affected by the accompanying flow between the single threads.
Furthermore, since the sway of the single threads is reduced, the probability that the single threads exit the discharge hole and come into contact with each other while uncoagulated becomes extremely small.
It is possible to significantly reduce the shortest distance between discharge holes, which was conventionally considered common sense. In addition, as this distance is reduced, the accompanying flow surrounding the single fibers becomes integrated, forming a continuous hollow cylindrical screen, and the effect of fixing the single fibers is greatly increased, repeating a favorable cycle. is possible. It has been confirmed that even if the shortest distance between discharge holes is reduced to 27 mm, there will be no effect on process performance or yarn quality.

As is clear from the above, the present invention speeds up mud spinning (in some cases, makes industrial production extremely easy).The present invention also enables mud spinning of multi yarns and fine denier yarns in the same way as ordinary yarns. This is an extremely effective method for implementing this at a high level.

Furthermore, if the discharge hole is multiplied, the cross-sectional area of the discharge hole increases for the same denier, and the draft substantially increases.

の定義は、巻取速度/吐出線速度である。
It is well known to those skilled in the art that when the draft exceeds a certain upper limit, spinnability is adversely affected. Therefore, if it is necessary to lower the draft to an appropriate level that does not exceed the upper limit, the diameter of the discharge hole should be reduced. However, as a matter of course, pore clogging with foreign matter increases and the frequency of replacing the spinneret increases. However, in the method using the spinneret according to the present invention, the upper limit of the appropriate draft is about 40% higher than when using a normal multi-array spinneret. Therefore, the need to reduce the discharge hole diameter is alleviated.
The frequency of spinneret replacement is reduced. The reason is not clear, but it is presumed that the upper limit value has increased because the flow velocity distribution during discharge of the stock solution has become smaller, and therefore the draft distribution between single yarns has become narrower. The definition of draft in the invention is winding speed/discharge linear speed.

Regarding the speed of the present invention, it is preferable that the coagulation bath supply port for supplying the coagulation bath vertically in a fluid manner is located in front of the spinneret in front of the spinneret in the traveling direction of the discharged yarn. It is preferable that Furthermore, it is more preferable that the coagulation bath is rectified by passing through a rectification component described in, for example, 01 (Sho 57-178281).All of these have the effect of further reducing turbulence of the coagulation bath after the spinneret. It is from.

Furthermore, it is more desirable that the shortest distance between the drilled discharge holes be two or more cuts. If this shortest distance becomes 2 or more, the number of discharge holes will increase especially when spinning multi-lead yarn, so the arrangement of discharge holes should be P, C, D, (
Pitch of C1rcle Diameter)
will increase, and the diameter of the spinneret will increase. Therefore, local irregularities in the residence time of viscose and irregularities in temperature or viscosity within the viscose spinneret occur, which can drastically affect the quality of the spun yarn. This is because the yarn after being processed may exhibit abnormalities in physical properties such as strength and elongation, or may not be able to withstand the tension applied during the process, resulting in breakage or fluffing.

Moreover, it goes without saying that the present invention is not limited to multi-threads or fine denier threads, but also exhibits good effects even when using normal threads.

In the method of the present invention, as the flow rate of the coagulation bath increases, the shaking of the single yarn immediately after discharge decreases and the yarn runs more stably. In comparison, the upper limit speed of movement increases dramatically.
