３４６２号公報に記載されたものが提案されている。It has been found that the structure of the false twist nozzle is technically important in order to produce high-quality bound spun yarn at high speed and at low cost using the above-mentioned known techniques. Therefore, as a false twisting nozzle that takes this point into consideration, Japanese Patent Application Laid-Open No. 50-95528
No. 1, JP-A No. 52-5337 and JP-A No. 52-6
The one described in Publication No. 3462 has been proposed.

号公報に記載されている仮撚ノズルは下流側糸道を小径
孔とし下流側糸道を大径孔とし。JP-A-50-95528, JP-A-52-5337
The false twisting nozzle described in the publication has a small diameter hole in the downstream yarn path and a large diameter hole in the downstream yarn path.

両孔の接続部を円鉗面又は球状面などの形状とし。The connecting part of both holes has a shape such as a circular or spherical surface.

この接続部に仮撚ノズルの軸線に対して傾き、かつ接続
部の中心より偏心した位置に開口した流体導入孔を設け
た構造のものである。しかしこの構造の仮撚ノズルにお
いては９次の如き欠点を有する。This connection part is provided with a fluid introduction hole that is inclined with respect to the axis of the false twist nozzle and opened at a position eccentric from the center of the connection part. However, the false twisting nozzle having this structure has the following drawbacks: 9th order.

すなわち、まず第１に、大径孔となした下流側糸道の直
径は、小径孔である上流側の糸道の直径に、流体導入孔
の直径の２．、声の直径を加えた直径よりも大きな直径
とする必ｌ１ｌ−があることである。That is, first of all, the diameter of the downstream yarn path, which is a large diameter hole, is 2.0 mm larger than the diameter of the upstream yarn path, which is a small diameter hole, and the diameter of the fluid introduction hole. , the diameter must be larger than the diameter plus the diameter of the voice.

撚を付与する際の加熱能力は、加圧流体が作用する空洞
の直径が大きい程低下し、前記の仮撚ノズルは加熱性能
を十分＾められないという欠陥をさけることができなか
った。In general, when applying false twist to a fiber bundle or yarn with a false twisting nozzle that uses a fluid, the heating ability decreases as the diameter of the cavity on which the pressurized fluid acts increases; ＾I couldn't avoid the defect of not being recognized.

ルは傾き角を大きくとれないために、この加熱能力を低
下させるのである。Secondly, in the above-mentioned false twisting nozzle, there is a structural restriction that the inclination angle of the yarn passage hole with respect to the axis cannot be made large. In other words, if the fluid introduction hole opened in the connection part is provided perpendicularly to the wall surface of the connection part, and the inclination angle of the fluid introduction hole is increased without changing the diameter of the fluid introduction hole, the diameter of the thread introduction hole will increase. The length of the opening of the fluid introduction hole when viewed in a direction perpendicular to the axis increases as the above-mentioned inclination angle increases, so the opening has to extend to the small diameter hole on the upstream side. If the fluid introduction hole is opened from the connection part to the small-diameter hole part, the yarn being twisted in the ballooning state will be caught at the open end, which will prevent ballooning and twisting. . In general, the heating capacity decreases as the inclination angle of the fluid introduction hole with respect to the axis of the thread conductor 4 becomes smaller, so the false-twisting nozzle having the above structure cannot have a large inclination angle, so the heating capacity is reduced.

ど、ノズル入口での吸引−が低下す−る。Further, Japanese Patent Application Laid-open No. 52-63462 also discloses a false twisting nozzle having a similar structure. This false-twisting nozzle also has almost the same shape as the one shown in JP-A-50-95528, but the difference from JP-A-50-99528 is the opening position of the fluid introduction hole. is located in the large diameter hole, and the distance between the downstream end of the small diameter hole and the opening end of the fluid introduction hole is large, which makes it difficult to perform stable heating and untwisting, not to mention the heating efficiency of the false twisting nozzle. I couldn't avoid my shortcomings. Furthermore, the larger the above distance, the lower the suction at the nozzle inlet.

本発明の目的は上記の如き従来技術の欠陥を、除去し、
加熱能力にすぐれ、連続運転においても安定して稼動す
る新規な仮撚ノズルを提供せんとするものである。The purpose of the present invention is to eliminate the deficiencies of the prior art as described above,
The present invention aims to provide a new false twisting nozzle that has excellent heating ability and operates stably even in continuous operation.

本発明は上記の目的を達成するため次の如き構成を有す

In a fluid false twisting nozzle equipped with a fluid introduction hole that has a fluid introduction angle that is inclined at a tilt angle and that opens into the yarn passage hole at an angle from the axis of the yarn passage hole, A connecting part consisting of a truncated conical or spherical surface is provided in the middle of the large diameter hole.

２内に噴出する。In FIG. 1, a nozzle body 1 has a thread passage hole 2 extending in its longitudinal direction. This thread passing hole 2 has a length X and a thread guiding part 3 degrees widening towards the front, and a small diameter hole part 4 having a length Y.
A conical connecting portion 5 and a large diameter hole portion 6 having a length of 2 are arranged in this order on the axis O of the nozzle body. - One open end of the force fluid introduction hole 7 is open across the connecting part 5 and the large diameter hole part 6, and the other open end is open to an annular v8 provided on the outer periphery of the nozzle. The fluid introduction hole 7 is eccentric with respect to the axis O of the nozzle body 1 and has an introduction angle α with respect to the axis O.
It is inclined with. Compressed fluid, usually compressed air, is a compressed air source (
The fluid is ejected from the fluid introduction hole 7 into the yarn passage hole 2 through the annular chamber 8 of the nozzle body 1 (the outer cylinder of the false twisting nozzle is not shown).

第１図においては流体導入孔６の数は１個の例を示した
が複数個（２〜６個）の方が好ましい。Although FIG. 1 shows an example of one fluid introduction hole 6, it is preferable to have a plurality of fluid introduction holes (2 to 6).

It is best to have a shape that follows the outer periphery of the la. Further, the large-diameter hole portion 6 may also have a conical surface (for example, a conical angle of 3 to 5 degrees) from the middle, as similarly indicated by a broken line 6'. Alternatively, the large diameter hole 6 may have a conical surface.

する機能を持たせてるので。The diameter of the small diameter hole 4 is indicated by Dl, and this hole preferably has a circular cross section and has a function of controlling the ballooning of the yarn that occurs when the yarn is subjected to false twisting. Because it is.

糸条の太さにもよるが通常５ｍｍ以下とするのが良い。Although it depends on the thickness of the yarn, it is usually good to set it to 5 mm or less.

The smaller the distance between the Q point and the downstream end of the small diameter hole 4, the better the bound spun yarn can be obtained. However, in the false twisting nozzle according to the present invention, since the fluid introduction hole 7 is provided so as to straddle the connecting portion 5 and the large diameter hole portion 6, the above-mentioned distance #L
is usually several lll or less, and even when cotton with an average fiber length of 201 is used as raw material, it can be reduced to 115 or less, generally 1/10 or less, of the average fiber length.

上好ましいことがわがった。As shown in FIG. It has been experimentally found that it is preferable that the value represented by 2A=□Q1+dcosα is in the range of 1.1 to 1.8, where α is the fluid introduction angle with respect to the axis 0 of the nozzle body.

また小径孔部の最下流端の断面積と大径孔部の最上流部

側、外側のいずれでも良い。FIG. 2 shows in detail the state in which the fluid introduction hole 7 opens in contact with the inner wall of the large-diameter hole 6 deviating from the axis O of the nozzle body 1. Of course, it is ideal that the inner wall of the large diameter hole 6 and the outer inner wall of the fluid introduction hole 7 are in contact with each other in an eccentric manner, but the diameter of the fluid introduction hole 7 is not limited to the state in which they are in contact with each other. If it is about 115, it can be either inside or outside of the above state.

されないで回転させるようにすることが必要である。The connecting portion 5 is for connecting the small-diameter hole portion 4, the large-diameter hole portion 6, and the hollow portions of different diameters, and as mentioned above, it may be a truncated cone shape or a spherical cavity, but in the case of a truncated cone shape, It is preferable that the apex angle β be a darkness of π/3 to π. The connecting portion 5 is configured to encourage the flow of high-speed fluid ejected from the fluid introduction hole 7 to become a strong swirling flow without being disturbed, and to efficiently apply suction to the yarn. It is necessary to allow the fiber bundles to rotate undisturbed by this fluid.

The diameter of the most upstream side of the large diameter hole 6 is suitably the diameter of the small diameter hole 4 plus 0.5 to 1.5 am. The diameter of the small diameter hole 4 has an appropriate range depending on the yarn count to be spun, in order to improve the yarn quality and the heating performance of the false twisting nozzle.

It acts to send out the fibers on both sides of the fiber bundle that has been drafted and widened at @12 in an open-end state,
The suction tube 14 functions to converge the open-ended fibers onto the surface of the core fiber bundle heated by the fluid false twisting nozzle K. Therefore, the bound spun yarn obtained by the apparatus shown in FIG. 3 is a high-quality yarn in which surface fiber bundles are wound regularly and in a fixed direction around a core I miscellaneous bundle without twist.

る。On the other hand, the fluid false twisting nozzle according to the present invention can be equally effectively used in a spinning device in which the fiber bundle supply device is simply a pair of rows, and the fluid false twisting nozzle is placed directly behind the rollers. Although the 1 bound spun yarn obtained in this case has a random winding pattern on the surface II, it has a stable appearance that can be used as a product.
