FIG. FIG. 4 is a drawing corresponding to FIG. 3 of the comparative example. As shown in the drawing,
In the yarn fluid treatment device of the present invention, the yarn passing hole 1 gradually expands from the yarn inlet 2 to the yarn outlet 3 so that the opening area is larger at the yarn outlet 3 than at the yarn inlet 2. have. in this case,
In addition to the linear expansion mode as shown in the embodiment shown in FIG. 2, a curved or stepwise expansion configuration may also be used. Furthermore, on the inner wall of the thread thread hole 1,
At least one fluid introduction hole 4 is provided near the yarn inlet 2, approximately halfway between the yarn inlet 2 and the yarn outlet 3, so that the yarn is passed so that the main traveling direction of the jet flow is in the direction of the yarn outlet 3. The opening is inclined with respect to the axis of the hole 1. The yarn outlet 3 is in the yarn take-up direction (the line direction connecting the opening side and the opposite opening side of the fluid introduction hole).
The average inner diameter l 1 is the average inner diameter perpendicular to it l 2
It has a shape that is more than 1.3 times larger. For example, in FIG. 1, the yarn outlet 3 has a rectangular shape that is long in the yarn take-up direction (the line direction connecting the opening side and the opposite side of the fluid introduction hole), and the embodiment in FIG. 5 has a rectangular shape. The upper and lower short sides are arcuate, and the embodiment shown in FIG. 6 has an elliptical shape.

率よく製造することができる。 The yarn is processed by the filamentous fluid treatment device of the present invention, in which the yarn Y is introduced into the yarn passing hole 1 from the yarn inlet 2, and is ejected from the yarn outlet 3 together with the fluid supplied from the fluid introduction hole 4. This is achieved by immediately pulling the yarn Y in the direction M, which is the same as the opening side direction of the fluid introduction hole 4 (i.e., the direction in which the average radius of the yarn outlet 3 is l 1 ), and the desired intertwining property and robustness are achieved. It is possible to efficiently produce a bulky textured yarn having excellent loops, slack, etc.
本考案の糸条流体処理装置は上記のごとき構造
を有するが、以下にその作用について説明する。 The yarn fluid treatment device of the present invention has the above structure, and its operation will be explained below.
本考案の糸条処理装置において最も重要な点
は、糸条出口３における糸条引出し方向の平均内
径l1を糸条引出し方向と直角方向の平均内径l2よ
り大きくしたことである。これによつて流体消費
量を増加させることなくループ、たるみの起生効
果を高めるとともに、その堅牢性を格段に向上し
得る。この理由としては、糸条出口３においてl2
がl1より小さいため、流体の噴射方向に対してほ
ぼ垂直方向に引出された糸条の側面に対して作用
しない糸条断面方向の無駄な噴流が減少し、その
減少分に相当する噴両が、引出された糸条の長手
方向に充当されることになり、糸条に対する噴流
の作用時間が長くなつて、糸条側面への噴流の作
用効果が向上させられるものと考えられる。 The most important point in the yarn processing device of the present invention is that the average inner diameter l 1 in the yarn drawing direction at the yarn outlet 3 is made larger than the average inner diameter l 2 in the direction perpendicular to the yarn drawing direction. As a result, the effect of generating loops and slack can be enhanced without increasing fluid consumption, and the robustness can be significantly improved. The reason for this is that l 2
Since l is smaller than 1 , the unnecessary jet flow in the cross-sectional direction of the yarn that does not act on the side surface of the yarn drawn out in a direction almost perpendicular to the fluid jet direction is reduced, and the jet flow corresponding to the decrease is reduced. is applied in the longitudinal direction of the drawn yarn, which lengthens the time the jet jet acts on the yarn, and is thought to improve the action and effect of the jet jet on the side surfaces of the yarn.
すなわち、l2がl1とほぼ等しいかl1より大きい
場合には、第４図から明らかなように、糸条出口
３から噴射される噴流（図中αの角度をもつて外
へ拡散する。）が糸条Ｙの側面に作用しない無駄
な領域Ａが存在する。しかし、この領域Ａはl2を
小さくすることによつて減少することができる。 That is, when l 2 is approximately equal to l 1 or larger than l 1 , as is clear from Fig. ) exists on the side surface of the yarn Y in a useless area A. However, this area A can be reduced by reducing l 2 .
糸条出口で乱されたフイラメントに噴流が当た
る必要量小限までl2を小さくし、糸条出口開口面
積が前記第４図の場合と同じになるようにl1を大
きくした、第３図に示す本考案の流体処理装置の
例では、前記の無駄な領域Ａは存在せず、しかも
該領域Ａに相当する噴流が引出される糸条の長手
方向進行方向に充当される。このため糸条出口３
から噴射された噴流が極めて有効に糸条の側面に
作用することになり、前述した本考案の効果を奏
しうるものと考えられる。 Figure 3 shows that l2 was reduced to the minimum necessary amount for the jet to hit the filament disturbed at the yarn outlet, and l1 was increased so that the yarn outlet opening area was the same as in Figure 4 above. In the example of the fluid treatment device of the present invention shown in , the waste area A does not exist, and moreover, the jet flow corresponding to the area A is applied to the longitudinal traveling direction of the yarn to be drawn out. For this reason, yarn outlet 3
The jet stream injected from the thread acts extremely effectively on the side surface of the yarn, and it is considered that the above-mentioned effects of the present invention can be achieved.
ここで第３図に示す本考案の流体処理装置と第
４図に示す比較例の流体処理装置の糸条処理効果

ープ、たるみの起生効果が格段に優れ、また形状
堅牢性が同じ程度のループ、たるみを得ようとす
る場合には流体消費量が少なくてよく、加工速度
を高く設定できるなどの効果を奏する。 Here, when comparing the yarn processing effects of the fluid treatment device of the present invention shown in Fig. 3 and the fluid treatment device of the comparative example shown in Fig. 4, it is found that the fluid treatment device of the present invention has the same fluid consumption and the same processing speed. In some cases, the entangling property and the effect of creating loops and sag are significantly superior, and when trying to obtain loops and sag with the same degree of shape robustness, less fluid consumption is required and the processing speed is high. It has the effect of being able to be set.

が1.3以上の場合に極めて良好な結果が得られた。 In addition, yarn processing devices in which the cross-sectional area of the fluid introduction hole 4, the inclination angle with respect to the yarn threading hole 1, and the opening area on the inner wall of the yarn threading hole 1 are made the same, and l 1 /l 2 are variously changed. When we compared the entangling properties, loop and sagging effects, and robustness of the resulting processed yarns, we found that when the l 1 /l 2 ratio was 1.3 or more, it was extremely good. The results were obtained.
次に、本考案の糸条処理装置において他の重要

変換点近傍に噴流が速度低下されることなく有効
に噴射されて、糸条の開繊及びループ起生作用が
向上するためと考えられる。 Next, another important point in the yarn processing device of the present invention is that the fluid introduction hole 4 is opened on the inner wall surface of the yarn passing hole 1 on the same side as the yarn drawing-out direction M at the yarn outlet 3. This can significantly improve the effects of creating entanglements, loops, and sag. The reason for this is that, as shown in FIG. 2, the direction change from the jetting direction of the fluid of the yarn Y at the yarn outlet 3 to the direction M that is substantially perpendicular to this direction occurs at a relatively upper end of the yarn outlet 3. As a result, the action length L of the jet on the side surface of the yarn Y becomes longer, and the jet is effectively injected near the yarn direction conversion point without reducing the speed, thereby opening and looping the yarn. This is thought to be due to an improvement in the inducing effect.

た効果をさらに助長することができる。 Furthermore, in the yarn processing device of the present invention, a more important point is to make the opening area of the yarn outlet 3 larger than the opening area of the yarn inlet 2. This prevents a decrease in the speed of the jet flow and also lengthens the contact time of the jet flow with the yarn, thereby further promoting the above-mentioned effects.
