The present inventor has hitherto proposed a method for producing spun yarn kite yarn using continuous multifilament yarn as a component, which consists of a continuous multifilament yarn that is substantially untwisted in the heated region of the core yarn that runs while being heated. A method was proposed in Japanese Patent Application No. 131158/1983, etc., in which the twisted yarn is actively fed and entangled at a speed at least faster than the withdrawal speed of the core yarn, and then untwisted.

The present inventor has discovered that by using these methods, the loops of the twisted yarn are tightly entangled around the core yarn and then wound back, making it possible to manufacture spun yarn kite yarn that is easy to handle in subsequent processes such as weaving, knitting, and weaving. And so.

However, when using these methods to supply a fixed length of core yarn using a feed roller, the tension is extremely high and unstable due to twisting and shrinkage due to heating of the core yarn, and the feed rate (ratio of feeding speed to withdrawal speed) is extremely high and unstable. For example, if the circumferential speed of the feed roller is v1 and the circumferential speed of the delivery roller is v2, the feed rate F is F=(V.

On the other hand, if the core yarn is supplied with a constant tension using a gate tensor and a tension washer, fluctuations in tension can be kept to a minimum and stable processing becomes possible.
The supply yarn length of the core yarn changes due to fluctuations in the unwinding tension of the core yarn, and it is extremely difficult to maintain the same tension for multiple spindles over a long period of time, and in severe cases, the denier of the processed yarn also changes. This also caused problems.

Furthermore, these spun yarn kite yarns have a raw filament yarn as a core yarn (a filament yarn obtained by a spinning-drawing process, etc., which has not been subjected to texture processing such as false twisting or pressing), and is referred to as a modified filament yarn below. When using woven fabrics, the apparent bulkiness is almost satisfied with the looped yarn due to the yarn form, but there is a problem that the texture becomes stiff and the actual bulkiness is low when made into a fabric.

Here, as a method of laminating and entangling the core yarn with the core yarn, there is an alternative method, as shown in FIG. The thread is sent out by a thread feed roller 4 that rotates at a speed of four times or more, and the thread is fed out by an ejector 5 that actively sends out the thread together with a high-speed fluid provided behind the thread feed roller 4. The ejector 5 collides with a collision plate 24 made of a flat surface, a curved surface, or a combination thereof in front of the ejector 5, and slides along with the fluid on a guiding guide plate 22 connected to the collision plate 21 while diffusing the fluid. The fibers are opened and wound around the surface of a rotating conical or cylindrical spindle 23 to form a filament layer, and the filament layer is continuously heated by the spindle and runs through the hollow hole. A method of winding the core yarn inside out at the tip of the spindle at 23° and pulling it out while intertwining it, or a method similar to that shown in FIG. The fluid heating element 1 is opened at a speed more than four times the surface speed of the delivery roller 14 while
It is preferable to wrap the core thread 8 around the core thread 8, which runs while being heated by the method 3, but it is preferable to wind the core thread 8 while being heated by a fluid heating element, a mechanical false-twisting spindle, or a friction heating element, etc. In the heating region of the core yarn made of filament yarn, a twisted yarn made of other substantially non-twisted multifilament yarn is actively supplied at a speed at least four times the withdrawal speed of the core yarn, and the yarn is twisted. The method is not particularly limited as long as it is a method of entangling by untwisting after entangling.

このような方法により芯糸に搦み糸が強固に捲付き、絡
みあった糸を製造するに際して搦み糸の絡合点より上流
側に芯糸の加熱状態を熱セットするための加熱ヒータを
設けるのは本発明では必須のことである。
With this method, the twisting yarn is tightly wound around the core yarn, and when producing intertwined yarns, a heater is installed upstream from the entanglement point of the core yarn to heat set the heating state of the core yarn. Providing this is essential in the present invention.

すなわち搦み糸の絡合点の以前に加熱体をもうけること
により熱可塑性繊維の芯糸の収縮力によって、余分のた

され易くし、同時に撚縮み率を低下せしめて撚形態を安
定化させ、張力変動、撚数変動を解消して、芯糸の定長
供給による非常に安定な加工が可能となったのである。
In other words, by providing a heating element before the entanglement point of the twisted yarn, the shrinkage force of the core yarn of the thermoplastic fiber absorbs excess slack, lowering the Young's modulus of the heated yarn and making it easier to heat. At the same time, the twist shrinkage rate was lowered to stabilize the twist form, eliminating tension fluctuations and twist number fluctuations, making it possible to perform extremely stable processing by supplying a constant length of core yarn.

ここで加熱体としては通常のプレートヒーターが好適に
使用されるが、ホットローラータイプ、中空のチューブ
ヒーターなどであってもよい。
Here, as the heating element, a normal plate heater is suitably used, but a hot roller type, hollow tube heater, etc. may also be used.

又この加熱体を搦み糸の絡合点の上流側におくのは、芯
糸の加熱域で熱セットすることにより、前述の如く安定
した加工が可能になるばかりでなく、引続いてもうけら

同時に仮撚加工されるというメリットも合せ有するから
であり、又芯糸が嵩高加工されクリンプが与えられるこ
とにより搦み糸との摩擦が大きくなり、絡合性も向上す
る。
In addition, the reason why this heating element is placed upstream of the entanglement point of the threads is that by setting the heat in the heating area of the core thread, not only stable processing as mentioned above is possible, but also continuous processing. This is because the core yarn is untwisted by the fluid heating element that is attached to the core yarn, and the core yarn is simultaneously subjected to false twisting. The friction becomes larger and the entanglement property also improves.

又芯糸にクリンプが与えられることにより糸条が柔かく
なり嵩高で柔軟な布帛が得られるのである。
Furthermore, by crimping the core yarn, the yarn becomes softer and a bulkier and more flexible fabric can be obtained.

他方加熱体を絡合点と流体加熱素子の間にもうけると、
絡合性の悪い絡み糸を加熱体でしごくことになり、また
通過糸のヤング率を低下させるため流体加熱素子からの
撚の遡及を妨げる結果となり搦み糸の絡合性は不充分に
なるなどの問題があり好ましくないからである。
On the other hand, if a heating element is placed between the entanglement point and the fluid heating element,
The entangled yarns with poor entanglement properties are squeezed by the heating body, and the Young's modulus of the passing yarns is reduced, which prevents the twisting from returning from the fluid heating element, resulting in insufficient entanglement properties of the entangled yarns. This is because there are problems such as this, which makes it undesirable.

また、搦み糸を芯糸の引出し速度の4倍以上の速度で積
極的に供給するのは、搦み糸を芯糸に強固に捲付け、絡
合させ、見掛上の実撚として流出させるために必要で、
4倍未満では絡合性の劣ったものとなるためであり、好
ましくは5倍以上がよい。
In addition, actively feeding the twisting yarn at a speed more than four times the withdrawal speed of the core yarn means that the twisting yarn is tightly wound around the core yarn, entangled, and flows out as an apparent real twist. necessary to make
This is because if it is less than 4 times, the entanglement property will be poor, and preferably it is 5 times or more.

ただダブリング(搦み糸の供給速度/芯糸の引出し速度
)が余りに大きくなると、絡合性は向上するが、得られ
る糸が太くなるから用途に応じて適宜設定すればよい。
However, if the doubling (supplying speed of the threaded yarn/drawing speed of the core yarn) is too large, the entanglement property will improve, but the resulting yarn will become thicker, so it may be set appropriately depending on the application.

このように本発明方法によれば簡単な設備で、一工程で

As described above, according to the method of the present invention, bulky spun yarn-like yarn can be stably and inexpensively obtained in one step using simple equipment.
