る。更には糸が切れて生産不可能となる。(Prior art) Conventionally, a method for rationally producing spun yarn has been to cut a continuous long fiber bundle (so-called tow) into thin fiber bundles of a predetermined thickness by shredding, and then conjugate these. It is known that the fibers can be made into spun yarn-like threads. However, the main point of this sword body is how to evenly tear the thick tow to obtain threads of a certain thickness, and if the tow fibers are disordered, group cuts will occur immediately, which can be severe. Spots appear. Furthermore, the threads break and production becomes impossible.
現実の生産現場においては、トウ繊維の取扱いに注意し
ていてもトウが乱れたり、牽切機械の調整不良によって
工程のトラブルを多々発生せしめている。In actual production sites, even if the tow fibers are handled with care, problems often occur in the process due to the tow being disorganized or the tension cutting machine being poorly adjusted.

The present invention is a method for producing a yarn, characterized in that the constituent fiber bundles have a twist of 90.2 times or more.

。FIG. 1 is a process diagram showing an example of the process of producing yarn by cutting and conjugating continuous long fiber bundles. In Fig. 1, reference numeral 1 denotes an undrawn continuous fiber bundle (tow) that is a raw material, which is supplied from p-lar 2, heated by heater 3, and then drawn between p-lars 2 and 4. Nagishin tow is formed, which is then pulled and shredded at a high magnification between rollers 4 and 5 to become thin short fiber fleece, which is further tied together by a rotating nozzle 6 so that it can be handled as yarn, and then passed to roller 7. After that, it is wound up by winder 8. FIG. 2 is a process diagram showing an example of such a tow manufacturing process, and FIG. Roll it up and return it as unstretched tow 1.

り10回以下が望ましい。On the other hand, in the case of the tow used in the present invention, as shown in FIG. After the tow is applied, as shown in FIG. 2 (c), the tow is rolled up with another winder 12 while being aligned to form an unstretched tow 1'. In this case, if the required number of twists is given, the r-twisted yarn may be replaced by untwisted yarn. The undrawn tow 1' obtained in this way is fed to the process shown in Figure 1 and made into yarn, but when the undrawn tow is stretched and then subjected to tension cutting as in this case, The number of twists applied decreases by the stretching ratio, so
Therefore, it is necessary to hang it on more eyes. In other words, before cutting, the constituent delicate bundles must be subjected to at least 0.2 strokes per m. If the number of twists is too large, the twist itself will inhibit tension cutting, so it is desirable that the number of twists is at most 10 twists per m.
また、併合の数はあまり少いと斑が目立ったり糸切れに

0本以上の本数を保てる程度に本数をとどめた方が良い
。Furthermore, if the number of mergings is too small, unevenness will become noticeable or thread breakage will occur, so at least 6 or more are required, preferably 15 or more. On the other hand, if the number of fibers is increased too much, they will not merge, and they will easily thaw each other, so the number of single fibers in each constituent fiber bundle should be at least 2.
It is better to keep the number to a level that keeps the number above 0.

紡糸する段階で予め行なっておくなど、適宜性なえば良
い。As the continuous fiber bundle to be used, synthetic fibers are preferable from the viewpoint of productivity, cost, and product functionality, and among them, polyester is suitable for use in products and has the best adaptability, but other materials may of course be used. In addition, if stretching is necessary, in addition to connecting it with the process before tension cutting as in this example, it can be performed in advance, for example, in conjunction with the process of aligning the constituent fiber bundles, or at the stage of spinning the constituent fiber bundles. It is fine as long as it is appropriate, such as keeping it in place.

分割して捲き取り、多数の構成未延伸繊維束Yとしたが

能である。In the above example, the fibers are divided and wound using a large number of winders 11 to form a large number of undrawn fiber bundles Y, but instead of dividing into one, many thin undrawn fiber bundles are manufactured by another means. It is also possible to use it as the undrawn fiber bundle r.

れにならない。In order to obtain a uniform yarn, which is the object of the present invention, it is necessary to constantly perform tearing and shredding at a constant magnification between P-G-4 and P-5, for example, as shown in Figure 3 (A). If there is a part a that is entangled with the single fibers constituting the tow 1, smooth tension cutting will be hindered and the tow will break all at once, resulting in unevenness and thread breakage. On the other hand, Figure 3 (I:I) shows tow 1 used in the method of the present invention, which is obtained by twisting finely divided fiber bundles and then merging them. The fiber bundle is twisted at least 0.2 times or more per twist. Therefore, even if there is a tangled part of the single fibers, this twisting prevents the tangle from reaching the other constituent fiber bundles, so even if tension cutting is hindered by this tangled part, the entire tow will be cut at once. It doesn't break easily, and even in the worst case, the thickness of the constituent fiber bundles stays the same, so you won't get the strawberry-like slap or thread breakage.
即ち、この様な僅かの撚でもお互いの、繊維が絡まるの
が防がれるので糸切れや斑防止に驚くほど効果があり、
特に絡み易い繊維束には有効である。第三図は、牽切工
程に供給されるトウの状態を示す平面図である。In other words, even a slight twist like this prevents the fibers from getting entangled with each other, which is surprisingly effective in preventing yarn breakage and unevenness.
This is particularly effective for fiber bundles that are easily tangled. FIG. 3 is a plan view showing the state of the tow supplied to the tension cutting process.

仕様カンない。従って本発明は特にトウを牽切後連続的
に直接抱合するか或いはせいぜい2回ドラフトしながら
直接抱合して糸にする場合に効果が大きい。Furthermore, this method is particularly effective when the tension cut length is long. In other words, when the length of the stretch cut becomes long, long spots occur when the tow is cut in groups, and unnatural band-like (thick thread-like) spots appear on the woven or knitted fabric, which deteriorates the aesthetics. According to this method, it is possible to obtain a product with a natural appearance without the appearance of band-like spots, so even when the cutting gauge is long such as 150W or more, or even when it is long such as 300x or more, the product has a natural appearance. You can get the thread of In this case as well, it is possible to make the spots more visible by passing the tow through the gill or 2-mira draft several times while doubling it after cutting the tow, but as in this example, doubling after cutting the tow If you want to make thread immediately without any problems, there is no way to improve the specifications. Therefore, the present invention is particularly effective when the tows are directly bound together continuously after being cut, or when the tows are directly bound together while being drafted at most twice to form a yarn.

Subsequently, this was cut using a tension cutting gauge-600-9 tension cutting magnification of 38.
After cutting at a speed of 8 times, conjugation was applied with an air swirling nozzle of 4.0 m/d, and the yarn was wound into a 40-thread yarn at a speed of ao om/-. After twisting this yarn with +SOt/+a, it was made into a plain weave and finished with x2% alkali weight loss. Despite the very long fiber length, the fabric appearance was that of normal 64 katsuto spinning. The irregularities are random and natural like thread, and the repulsion is 92 because the fibers are extremely long.
A wonderful tropical-style fabric with little fuzz and excellent luster was obtained.

This was made into thread in the same manner as described above in the process shown in Figure 1, but the threads tended to break due to group cuts at slightly tangled parts of the tows, and the resulting fabric had a thread of 5 to 10 threads. -The strip-shaped long-circle plate about the width was noticeable and unwearable, reducing the quality of the appearance. In addition, to prevent this, the tension gauge was changed from 600 to 250.
When the length was shortened, this appearance was considerably improved, but at the same time, the anti-dust properties were reduced to 85 cm, the gloss was also reduced, and the characteristics of the ultra-cut length were lost accordingly.
