具体的に、本発明に係る紡績糸の製造方法及びその方法
によって得られた紡績糸の構造を説明する。Specifically, the method for producing a spun yarn according to the present invention and the structure of the spun yarn obtained by the method will be explained.

第２図は、本発明の紡績糸を製造す←実施態様を示す要
部の側面図である。FIG. 2 is a side view of essential parts showing an embodiment of manufacturing the spun yarn of the present invention.

られる。Since the rotating spinning chamber 6 is rotating at high speed, due to the action of centrifugal force,
The fiber bundle sticks to the inner wall, is torn off by the twisting, and is pulled out through the yarn discharge pipe 9 to the nozzle.
It passes through take-up rollers io, io' and is wound up as a spool 11.

構造の複合繊維をオープンエンド紡績法で紡績糸とする
ことによってのみ本発明の紡績糸が得られる。This spinning method is called an open-end spinning method, and the frictional behavior between the spinning chamber wall and the fibers and between the yarn 7 and the yarn discharge pipe tip member 8 are particularly important, and the above-mentioned specific structure is The spun yarn of the present invention can only be obtained by making the composite fiber into a spun yarn using an open-end spinning method.

束する力は小さい。The thread twisting mechanism used in this method differs from the conventional ring spinning method in that twisting is performed while the fiber bundles accumulated in the largest diameter part 3 of the spinning chamber are stripped off. The only thing that holds the weidong edge is the friction between the fiber bundle and the spinning chamber convergence surface and the friction between the fibers, and the force that restrains the movement of the fibers is small.

従って加ネン中の繊維はより安定な状態をとろうとして
移動しやすくなり、内外層で異なるヨリ構造となりやす
い。Therefore, the fibers in the layer tend to move in an attempt to maintain a more stable state, and tend to have different twist structures in the inner and outer layers.

と良い。1. To obtain the spun yarn according to the present invention, the spun yarn is brought into contact with the tip member 8 of a fixed yarn discharge pipe, and a temporary twisting effect is applied to the spun yarn 7 depending on the surface roughness or shape of the member 80. It is preferable to change the amount of bundled outer layer fibers described above by changing the degree of application of .

かくして本発明に係る紡績糸が得られる。Thus, the spun yarn according to the present invention is obtained.

紡績糸の構造について更に詳しく説明すると、糸のヨリ
構造がその糸軸に対し、外層部と内層部のヨリ数を相違
し、かつ外層部の繊維束が内層部を捲回するらせん径が
ほほ糸軸方向に同一とする。To explain the structure of spun yarn in more detail, the twist structure of the yarn is such that the number of twists in the outer layer and the inner layer are different from each other with respect to the yarn axis, and the fiber bundle in the outer layer has a helical diameter around the inner layer. Same in the yarn axis direction.

該「らせん径」とは、その糸軸方向と直角な平面に投影
した時に単繊維が作る円弧の直径をいう。The "helical diameter" refers to the diameter of an arc formed by a single fiber when projected onto a plane perpendicular to the yarn axis direction.

１た外層部とは糸軸に対し直角な断面にかいて、その軸
心から距る程、外層部であり、軸心に近い程内層部であ
る。The outer layer portion refers to the outer layer portion as viewed in a cross section perpendicular to the yarn axis, and the farther from the axis, the outer layer portion, and the closer to the axis, the inner layer portion.

従って内外層間に明確な層があるわけでない。Therefore, there is no clear layer between the inner and outer layers.

第３図口に従来リング精紡糸、第３図イに本発明に係る
紡績糸を示す。Figure 3 shows a conventional ring-spun yarn, and Figure 3A shows a spun yarn according to the present invention.

４に加えて、捲回状の結束繊維１５．１６で構威される
。Conventionally, the yarn 13 forms a thread in a constant twist angle direction 17, but the spun yarn 12 according to the present invention has a constant twist angle direction 1.
In addition to 4, it is constructed with wound binding fibers 15 and 16.

結束繊維束１５，１６のヨリ方向、ヨリ角度はランダム
である。The twist directions and twist angles of the bound fiber bundles 15 and 16 are random.

その比率で表現することができる。That is, when the number of twists read using the solution-addition method is T, and the originally set number of twists is To, it can be expressed as a ratio.

これは結束繊維の量と共に結束捲回の緊密度をもあらわ
してかり、（１）式にあ・いてｔ値が犬であれば結束繊
維量ｐよび結束密度が大であるといえる。This expresses the tightness of the bundle winding as well as the amount of bundled fibers, and if the t value is equal to the equation (1), it can be said that the amount p of bundled fibers and the bundle density are large.

ここでＴ値については防機での機械設定ヨリ数（紡糸室
の回転数とデリベリローラ速度で決定される。Here, the T value is determined by the machine set twist number (rotation speed of the spinning chamber and delivery roller speed) in the protector.

）でも良いし、測定試料のうち結束状部のない個所（短

あり、十分に製編織に耐えるものを得ることができる。Next, the relationship between the t value and the ironing resistance is shown in Table 1. In the range of 0<1≦035, the ironing resistance is excellent, and it is possible to obtain a material that can sufficiently withstand knitting and weaving.

糸での測定は３ケ所のフック状部に糸を走行させる。To measure using a thread, run the thread through hook-shaped sections at three locations.

これを３回繰返した後、パネルに巻取って視覚判定した

ぐれる。Furthermore, the spun yarn of the present invention has excellent bulk, and when evaluated in terms of product quality, it has excellent volume, thickness, tension, and stiffness.

１た比較例２で示すオープンエンド糸を用いた場合には
結束状繊維の比率力伏であり、製織時のしごき抵抗が低
く、しごきネツプが多発し生機での横スジ状欠点が目立
った。When the open-end yarn shown in Comparative Example 2 was used, the ratio of the bundled fibers was low, the ironing resistance during weaving was low, there were many ironing neps, and horizontal streak-like defects on the gray fabric were noticeable.

１た毛羽密度に関しては第４図で説明すると、織物から
の分解糸１２′，１３′の差で明らかである。Regarding the fuzz density, which is explained in FIG. 4, it is clear from the difference between the decomposed yarns 12' and 13' from the fabric.

本発明の紡績糸による分解糸１２′は糸の嵩高性、毛羽
長分布の均斉性等から起毛加工時にほぼ一定長の毛羽１
８が均一に立毛し、仕上起毛として一定長ｌでカット（
