長短複合糸及びその製造方法に関するものである。BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a long-short composite yarn in which short fibers are substantially untwisted and arranged randomly with respect to a multifilament yarn, and a method for producing the same.

うになってきた。2. Description of the Related Art Many proposals have been made for a long-short composite yarn in which a multifilament yarn and a short fiber are combined and a manufacturing method thereof. In particular, when synthetic fiber multifilament yarn and natural fiber are combined, long and short composite yarns that have the excellent mechanical properties of synthetic fiber and the excellent texture, moisture absorption, and water absorption functionality of natural fiber are obtained. ， In recent years, it has come to the spotlight again.

の少なくとも短繊維（束）は複合糸から脱落しないよう
に加撚されているのが一般的である。As a method for producing a long / short composite yarn, a method for compounding a short fiber coarse yarn or a spun yarn in a yarn processing process for a multifilament yarn, and a spun yarn production process (usually a spinning process) In general, in each method, at least the short fibers (bundles) of the long-short composite yarn finally obtained are twisted so that they do not fall out of the composite yarn. Target.
【０００４】このため，各短繊維はマルチフィラメント

て小さくなるので，天然繊維の形態不均一性に起因する
優れた風合や機能性を十分に生かすためには，長短複合
糸における短繊維の比率をできるだけ高くする必要があ
った。For this reason, the short fibers are arranged in a fixed direction with respect to the multifilament yarn, and the voids between the short fibers are extremely small. Therefore, the excellent feel and functionality due to the nonuniformity of the morphology of the natural fibers are obtained. In order to make full use of this, it was necessary to make the ratio of short fibers in the long-short composite yarn as high as possible.

の長短複合糸を製造することができなかった。However, if the amount of short fibers is increased,
Since the fineness of the long / short composite yarn is large, it is difficult to produce a long / short composite yarn with a fineness, and in order to widely meet the diversification of market needs in recent years, the fine / fine composite long / short composite yarn is suitable for thin applications. Could not be manufactured.

低下する。There is also a problem that the production speed is limited by twisting. In particular, in the method of compounding multifilament yarns in the manufacturing process of spun yarns, the production rate is no more than tens of meters / minute, and the production rate decreases as the total fineness decreases (the count increases).

た。As described above, in the conventional long / short composite yarn, even if the ratio of short fibers is reduced, the texture of natural fibers can be fully utilized, and it can also be applied to thin fabric applications. There is no long / short composite yarn with fineness, and it has been difficult to produce such a long / short composite yarn at high speed and efficiently.

Moreover, it is a technical subject to provide a long / short composite yarn capable of having a fineness and a manufacturing method capable of producing the long / short composite yarn at a high speed.

In particular, in order to fully utilize the texture of natural fibers, it was thought to be most preferable to combine short fibers in a substantially non-twisted state with multifilament yarns, which was thought to be extremely difficult in the past. As a result, the present invention has been reached.

(1) A long-short composite yarn in which a short fiber is combined with a multi-filament yarn, wherein the short fiber in the long-short composite yarn is substantially untwisted and has an entangled portion with the multi-filament yarn, and The long and short composite yarns, wherein the non-entangled parts are arranged in a random direction with respect to the multifilament yarns. (2) A method for producing a long-short composite yarn, which comprises applying water or an aqueous liquid to a multifilament yarn, adhering the short fibers to the multifilament yarn without twisting it, and then performing a fluid entanglement treatment.

と合成繊維を混合したものや合成繊維だけでもよい。The long-short composite yarn of the present invention is a composite of long fibers and short fibers which are multifilament yarns. The type of multifilament yarn or short fiber is not particularly limited, but synthetic fibers such as polyester and nylon are preferable as the multifilament yarn, and natural fibers are preferably used as the short fibers. It may be a mixture of a synthetic fiber and a synthetic fiber or only a synthetic fiber.

捲回していてもよい。In the long-short composite yarn composed of any of the above combinations, it is important that the short fibers are substantially untwisted. That is, since the short fibers are untwisted, the non-uniform shape of each short fiber is maintained, the voids between the short fibers become large, and even if the ratio of the short fibers in the long-short composite yarn is reduced. It is possible to sufficiently reflect the texture characteristics of the short fibers. Therefore, the short fiber ratio in the conventional long / short composite yarn was generally about 50% by weight or more, whereas in the long / short composite yarn of the present invention, the ratio can be set to 50% by weight or less. Depending on the fineness of the multifilament yarn and the thickness of the short fibers, a short fiber ratio of 3 to 40% by weight can be preferably adopted. Here, the fact that the short fibers are substantially non-twisted means that the short fiber bundle is not intentionally and mechanically twisted. The filament yarn may be gently wound around it.

繊維同士の交絡部が存在してもよい。Next, it is necessary for the short fibers to have an entangled portion with the multifilament yarn, which can prevent each short fiber from falling out of the long-short composite yarn. That is, in the present invention, untwisted short fibers are used in order to maximize the texture characteristics of the short fibers in a small amount. However, since each short fiber easily slips out, it is entangled with the multifilament yarn. It is necessary to have parts. If the short fibers and the multifilament yarn are mainly entangled, the entangled portions of the short fibers may be present.

どのような形態であってもよい。Further, it is important that the non-entangled parts of the short fibers are arranged in a random direction with respect to the multifilament yarn. That is, each short fiber or a small amount of short fiber bundles can independently show an arbitrary direction to the multifilament yarn. The single short fiber or the group of short fiber bundles may have any shape such as a wavy shape, a spiral shape, or a loop shape.

The short fiber 1 and the multifilament yarn 2 are entangled at an entangled portion 3, and each short fiber at the non-entangled portion 4. Untwisted and arranged in random directions. It can be seen that this form makes it possible to take full advantage of the form nonuniformity of the short fibers 1 and increases the porosity between the short fibers.

As a fine fineness long / short composite yarn with reduced
The texture due to the short fibers is not impaired.

After the water or the aqueous liquid is applied by the short fiber, the short fibers falling from the short fiber supply device 8 are attached to the surface of the multifilament yarn 5 in a wet state. Then, the short fibers and the multi-filament yarn 5 are entangled by the action of the fluid in the fluid treatment nozzle 9 to become the long-short composite yarn of the present invention, which is passed through the delivery roller 10 and wound into the package 12 by the winding device 11.

できなくなるので好ましくない。By applying water or an aqueous liquid to the multifilament yarn, it becomes possible to easily attach individual short fibers or a small amount of short fiber bundles to the multifilament yarn. Even without twisting, short fibers can be carried to the fluid treatment nozzle without dropping. When water or an aqueous liquid is not applied, the short fibers are less likely to adhere to the multifilament yarn and stable long-short composite yarn cannot be produced. In addition, when twisting the multifilament yarn, there are problems that the short fibers are difficult to adhere, the processing speed cannot be increased, and the subsequent entanglement treatment cannot be performed in the fluid treatment nozzle portion. In addition, when water or an aqueous liquid is previously applied to the short fibers and brought into contact with the multifilament yarn, the short fibers become heavy and fall off from the multifilament yarn before reaching the fluid treatment nozzle. Alternatively, the short fibers adhere to each other to form a lump, which makes it impossible to stably supply the multifilament yarn, which is not preferable.

The amount of water or aqueous liquid supplied to the multifilament yarn varies depending on the type of multifilament yarn or short fiber, the form, the composite ratio of both, the processing speed, etc., but is 10% by weight or more, particularly 20% by weight or more.

However, the short fibers referred to here are not spun yarns or rovings themselves, but individual short fibers or a small amount of short fiber bundles, and they are not twisted like spun yarns.

すればよい。Next, the multifilament yarn in which the short fibers are attached by the action of water or an aqueous liquid is subjected to a fluid entanglement treatment by a fluid treatment nozzle. As the fluid treatment nozzle, a commercially available interlace nozzle or Taslan nozzle is used. be able to. Above all, it is most preferable to use a fluid treatment nozzle having an air suction action on the yarn introducing hole side. With this type of nozzle, short fibers attached to the multifilament yarn simply by the action of water can be introduced into the nozzle without problems. , It is possible to perform fluid entanglement treatment with multifilament yarn. In order to have the air suction action on the yarn introducing hole side, the diameter of the yarn introducing hole may be made smaller than that of the outlet hole so that the fluid is preferentially discharged from the outlet hole side.

For example, when an interlaced nozzle is used, the fluid pressure is usually 1 to 5 kg / cm 2 , and the overfeed rate is 0 to 5%. Preferably. In the present invention, since the short fibers can be efficiently attached to the multifilament yarn by the action of water, it is not necessary to twist the multifilament yarn and the short fibers as in the conventional case,
It is possible to carry out the subsequent fluid entanglement processing without problems. Therefore, the processing speed can be increased and the productivity can be improved.
