Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention is directed to synthesis! The present invention relates to a method of applying a treatment agent to IH single thick denier yarn. Specifically, it relates to a method of applying a treatment agent to multiple thick filaments with a single filament denier of 150 d or more, particularly when cooling after melt spinning, applying a spinning oil as a treatment agent, and subsequently drawing. It can be applied to the application of processing agents.

[Prior Art] A method in which a spun synthetic fiber is brought into contact with the surface of an oil agent application roller to apply an oil agent, and the synthetic navy blue is brought into contact with the surface of the oil agent application roller in an opened state;
and devices are known, such as Utility Model Publication No. 47-342
No. 62, Utility Model Publication No. 51-13530, and Utility Model Publication No. 52-44648 disclose that the synthetic altI
It is described that a rotary opening roller made of a conductive material is provided in contact with f1.

[Problem to be solved by the invention] The above-mentioned Utility Model Publication No. 47-34262, Utility Model Publication No. 51-1
In the case of the method of applying an oil agent to synthetic fibers described in Japanese Utility Model Publication No. 3530 and Japanese Utility Model Publication No. 5244648, the following methods are described in these publications.
l When the single yarn deniers are 14 denier and 15 denier, such as 225de/16fil, each of these single yarns is spread by contacting with a respecting roller, and each single yarn is brought into contact with the surface of the treatment agent application roller. However, it travels while being buried in the processing agent adhering to the surface of the processing agent application roller, and has the effect of uniformly applying the processing agent.

However, in the case of a single yarn thicker denier yarn having a single yarn denier of more than 150 denier, which is about 10 times or more that of the above-mentioned synthetic fibers, each single yarn was opened on the surface of the treatment agent I/4 roller. Even if they run in parallel and come into contact,
Although the treatment agent is attached to the part of each single yarn that comes in contact with the roller, the treatment agent is not applied to the opposite side of the roller, especially in the case of a high viscosity treatment agent. The problem was that single filament breakage occurred frequently during subsequent drawing. In addition, the quality of the obtained single thick denier yarn is not constant, and there is a problem that there are large variations in properties such as strength and elongation.

In other words, in order to avoid applying a treatment agent to a melt-spun single thick denier yarn using a roller, and to actually produce a single thick denier yarn, the melt-spun single thick denier yarn should be treated in a treatment bath. A method is used in which a treatment agent is applied by passing it through.

However, in this case, there is a problem that excessive processing agents adhere to the single 6-denier yarn, and these excess processing agents are blown away in the subsequent process, deteriorating the working environment in the manufacturing process, as well as reducing processing agent consumption. There were problems such as the threads becoming too thick.

An object of the present invention is to provide a method that solves the problems in the conventional techniques and allows stable operation and obtains a single thick denier yarn.

[Means and effects for solving the problems] The structure of the present invention is such that, in a method for applying a treatment agent to a single thick denier yarn, a running single thick denier yarn is brought into continuous contact with the surface of a treatment agent applying roller. Then, a treatment agent diffusion element is brought into contact with the opposite side of the single yarn thick denier yarn and a part of the side where the treatment agent applying roller is in contact with the single yarn thick denier yarn. A method for applying a processing agent is characterized in that the diffusion suppressing force of the processing agent adhering to the denier yarn is destroyed so that the processing agent can be applied to the entire outer peripheral surface of a single thick denier yarn.

The present invention will be explained in detail using the drawings. All of the drawings show a processing agent application device used when carrying out the method of the present invention, and FIGS. 1 to 3 are one example thereof, and FIGS. 4 to 6 show other examples. . Fig. 1 is a front view of a processing agent application device provided with a processing agent diffusion element, Fig. 2 is a side view of Fig. 1, and Fig. 3 is an enlarged schematic view of Fig. 2 taken along the arrows. . FIG. 4 is a side view of a processing agent application device provided with a processing agent diffusion element, FIG. 5 is an enlarged schematic view taken along the v-v′ arrow in FIG. 4, and FIG. 6 is a Vl-Vl- in FIG. FIG.

The thickness of the upper thread thick denier thread, the thickness of the single thread thick denier thread is 1
In the case of yarns exceeding 50 d, without applying a treatment agent to a plurality of yarns in a bundle, the yarn Y when the number of single yarns is 5 as shown in FIG. The processing agent is applied to Yd and Ye by contacting the processing agent application roller 1 while running in parallel without intersecting or overlapping each other. As shown in FIGS. 1 and 2, the processing agent application roller 1 is rotating in a state in which a portion thereof is immersed in the processing agent trough 2. As shown in FIGS. Reference numeral 3 denotes a shaft that rotates and supports the processing agent application roller 1. A processing agent diffusion element 4 is provided below the processing agent application roller 1 . As shown in FIGS. 1, 2, and 3, the processing agent diffusion element 4 is provided across the processing agent applying roller 1 and the yarn Y, and is in contact with the processing agent applying roller 1 on the yarn Y. A contact portion 5 in contact with the opposite side to the position and a plurality of contact portions 6a16b in contact with a part of the side of the yarn Y in contact with the treatment agent application roller 1.
, 6C... are provided.

There are gaps 7a, 7b, 7c between the contact parts 6a and 6b.
... is provided, and the yarn Y passes through this gap.

Specifically speaking about the single yarn Ya, after the single yarn Ya is applied with the treatment agent in contact with the treatment agent application roller 1, the single yarn Ya is applied in a direction perpendicular to the position where the treatment agent is applied by the treatment agent application roller 1. One side of the contact portion 6a contacts the contact portion 6a, and subsequently, the side opposite to the position where the processing agent is applied by the processing agent application roller 1 contacts the contact portion 5. Desirably, further, the single yarn Ya is on the opposite side to the position where it contacted the contact portion 6a, that is, the other side in the perpendicular direction to the position where the treatment agent is applied by the treatment agent application roller 1. It contacts the contact portion 6b.

As mentioned above, the treatment agent is applied to the yarn Y by the treatment agent application roller 1, but since the yarn Y is a single yarn thick denier yarn, the treatment agent is applied to one side of the single yarn thick denier yarn. However, due to the surface tension of the processing agent itself, that is, the ability to inhibit diffusion of the processing agent,
It does not spread throughout the single thick denier yarn. Therefore, as described above, the contact portions 6a and 5.6b of the processing agent diffusion element 4 come into contact with each other, thereby destroying the processing agent diffusion suppressing force and causing the processing agent to adhere to the entire outer periphery of the single thick denier yarn.

The processing agent diffusion element 4 shown in FIGS. 1 to 3 has a cylindrical contact portion 5 with contact portions 6a, 6b, f3cm...
The gaps 7a, 7b, and 7c are formed by winding a wire having a diameter of 3 mm, for example.

The diameter of the cylinder forming the contact portion 5 is preferably in the range of 3 to 12 rrunφ, and the diameter of the wire wound around the cylinder is 0.5
to 5. C) The range is sφ. If the cylinder is too thin than 3 trmφ, it will be deformed by the winding wire or the single yarn will be bent suddenly, which is undesirable.
If it is thicker than this, the length of contact with the single yarn will be large, the yarn wobbling will be large, the spinning property will be deteriorated, and yarn breakage will easily occur.

In other words, the curvature of the contact portion 5 with which the single thick denier yarn comes into contact affects the quality and spinnability.

On the other hand, the diameter of the wire forming the contact parts 6a, 6b... is 0.
．． If it is thinner than 5 mφ, when the single thick denier yarn sways due to disturbance conditions such as wind, for example, the single thick denier yarn Ya running in the gap 7a will move to the gap 7b, and the single thick denier yarn Yb will move to the gap 7b. may overlap or intersect. When the single yarn thick denier yarns Ya and Yb overlap or intersect, the amount of treatment agent applied to the single yarn thick denier yarns Ya and Yb on the treatment agent application roller changes, and the yarn The quality of the yarn is not constant, and furthermore, the single thick denier yarn is suddenly bent, which deteriorates the quality.

Further, the diameter of the wire forming the contact portions 6a, 6b... is 5.
．． If it is thicker than 0 cmφ, the length of contact with the single yarn will be long, the yarn wobbling will be large, the spinning property will be deteriorated, and yarn breakage will easily occur.

In other words, the curvature of the contact portion 6 with which the single thick denier yarn comes into contact greatly affects the quality and spinnability.

It is assumed that the effective range of the curvature of the contact portions 5, 6a, 6b, etc. differs depending on the denier of the single thick denier yarn, but if it is within the above range, the single yarn denier is 380d.
It can be fully applied without any problem even if it is.

The shape of the processing agent diffusion element 4 is as shown in FIGS. 4 to 6, using a rod-shaped body with an elliptical cross section instead of a wire, and forming contact portions 5, 6a, 6b, 6C, . . . Gap 7a, 7
b, 7c may also be formed. The names of the parts in FIGS. 4 to 6 are the same as those shown in FIGS. 1 to 3, and the effects are the same. However, in terms of workability in manufacturing the processing agent diffusion element 4, uniformity of curvature of the contact portion, etc., it is better than those shown in FIGS. 4 to 6.
The ones shown in FIGS. 1 to 3 are better.

[Effects of the Invention] According to the present invention, the treatment agent can be efficiently applied to the single thick denier yarn using a roller, and the treatment agent can be spread over the entire outer periphery of the single thick denier yarn. This stabilizes the quality of the thick denier yarn and improves the spinning properties.

Also, +! It improves the working environment in the J construction process, prevents floors from becoming slippery due to scattering treatment agents, improves safety, and reduces production costs by avoiding the consumption of excess treatment agents. It has the effect of reducing the
