る方法およびその装置が数多く提案されている。"Prior Art" Conventionally, the wet yarn cooling method for false twisting of thermoplastic synthetic fibers involves guiding the heated and running heated yarn to the grafting body and at the same time introducing a liquid such as water. -5 Many rapid cooling methods and devices have been proposed.

などの欠点があった。As an example, a cooling device described in Japanese Patent Application Laid-Open No. 54-116N3 cools yarn by providing a grafting body curved with respect to the axis of the cooling pipe in a cooling pipe filled with cooling fluid. It has a structure. However, since this cooling device runs the yarn in a liquid, it has drawbacks such as increased resistance due to contact between the liquid and the yarn when the yarn is run at a high speed.

定して水を付与できない欠点があった。In addition, the water cooling device described in Japanese Patent Publication No. 47-50674 has a thin groove on the periphery of a rotating disk, and a nozzle injects liquid into the thin groove to cool the yarn in the thin groove. It has a structure that applies liquid. However, with this water cooling device, the yarn and the grafted body contact each other only at points, so they cannot be gripped sufficiently, and the running yarn vibrates, making it impossible to apply water stably. there were.

However, since a graft with a common curvature is used and a small amount of water is applied to the yarn, there is a drawback that the water bubbles with the yarn and eventually causes the yarn to vibrate.

糸切れが多発するなどの欠点があった。Furthermore, the false twisting method and system described in JP-A-55-51831 proposes a method of supplying a lubricating liquid to the belt contact surface of a cross-belt contact type friction false-twisting device. Since a large amount is applied, 1) there is a resistance to the running of the heated yarn, and when the speed is increased, the heated yarn vibrates, resulting in fuzzing and frequent yarn breakage.

通過性も悪化するなどの問題があった。When the false twisting process is sped up using the above-mentioned yarn cooling method and device, the heated yarn vibrates, fuzzing and yarn breakage occur frequently, and the quality of the resulting false twisted yarn is insufficient. Furthermore, there were problems such as deterioration in process passability.

The present invention was achieved as a result of extensive research in order to improve processing stability without feathering and to obtain high-quality false twisted yarn.

The present invention is characterized by the following features: (3) applying a liquid to the heated yarn on the braced thread body to cool it;
［作用］ 以下、本発明をさらに詳しく説明する。[Effect] The present invention will be explained in more detail below.
本発明は、仮撚加工の加熱部を積極的に冷却する方法に
おいて、冷却用接糸体の接糸部の曲率半径が、加熱糸条
の振動やバルーニングを抑制し、糸切れ、毛羽発生をお
さえ、工程通過性の問題のない均一で良質な加工糸を、
従来以上の高速で生産する際に重要な作用をすることを
確認したものである。The present invention provides a method for actively cooling the heating section of the false twisting process, in which the radius of curvature of the weaping section of the cooling grafting body suppresses vibration and ballooning of the heated yarn, thereby preventing yarn breakage and fuzzing. Uniform, high-quality processed yarn with no problems in passing through the process.
This has been confirmed to have an important effect when producing at higher speeds than conventional methods.
すなわち、本発明は従来常識のものより小さい曲率半径
の接糸部を有する冷却用接糸体を採用することにより、
高速においても加熱糸条を安定に走行させ、液体を付与
して効果的に冷却を達成することができることを究明し
たものである。That is, the present invention employs a cooling grafting body having a grafting portion with a radius of curvature smaller than that of conventionally common knowledge.
It was discovered that it is possible to run the heated yarn stably even at high speeds and to apply liquid to achieve effective cooling.
かかる接糸体の接糸部の曲率半径は、５００ｍｍ以上５
０００ｍｍ以下、好ましくは６００ｍｍ以上４００’Ｏ
ｍｍ以下、さらに好ましくは７００ｍｍ以上３０００ｍ
ｍ以下にするのが望ましい。The radius of curvature of the grafted part of such grafted body is 500 mm or more5
000mm or less, preferably 600mm or more 400'O
mm or less, more preferably 700 mm or more and 3000 m
It is desirable to make it less than m.
すなわち、冷却用液素体の接糸部の曲率半径が５０００
ｍｍを越える従来常識的な曲率半径のものでは、加熱糸
条の受ける接糸体との摩擦力が小さくなるので、糸張力

れが生産において多発し、結局、本発明の目的である仮
撚加工の高速化を達成することはできない。That is, the radius of curvature of the welded part of the cooling liquid element is 5000
If the conventionally common curvature radius exceeds mm, the frictional force exerted on the heated yarn with the grafted body becomes smaller, so the yarn tension can be lowered, but the vibration and ballooning of the heated yarn can be sufficiently suppressed. I can't. Therefore, if the false twisting speed is increased using such a graft, vibration and ballooning of the yarn will easily occur, leading to frequent occurrence of fluff and yarn breakage during production, and ultimately, the purpose of the present invention is to increase the false twisting speed. It is not possible to achieve high speed twisting.
また、該接糸部の曲率半径が５００ｍｍ未満であると、
糸条に発生する振動やバルーニングは十分抑制できるが
、加熱糸条が接糸体より受ける摩擦力が糸張力に影響す
る程度に大きくなり、毛羽発生や糸切れの増える原因と

、カサ胃性および伸縮性などが低下し、熱水収縮率が高
くなり、結局、本発明の目的である良好な糸質の加工糸
を得ることも、従来より高速化した仮撚加工を達成する
こともできない。Further, the radius of curvature of the welded portion is less than 500 mm,
Although the vibrations and ballooning generated in the yarn can be sufficiently suppressed, the frictional force that the heated yarn receives from the grafted material becomes large enough to affect the yarn tension, causing an increase in fuzz and yarn breakage. The twist propagation is hindered, the stretch recovery rate, bulkiness and elasticity are reduced, and the hot water shrinkage rate is increased, and as a result, it is difficult to obtain processed yarn with good quality, which is the objective of the present invention. , it is also impossible to achieve faster false twisting than conventional methods.
次に、本発明において、接糸体長手方向に垂直な接糸体

糸条の振動やバルーニングを抑え、さらに糸切れ、毛羽
発生をおさえ、高捲縮等の良好な加工糸を、しかも従来
以上の高速で生産する上で、好ましい作用機能を発揮す
るものであることを究明した。Next, in the present invention, the radius of curvature of the concave yarn path in the cross section of the graft perpendicular to the longitudinal direction of the graft suppresses vibration and ballooning of the yarn on the graft surface, and further prevents yarn breakage and fuzz. It has been found that the present invention exhibits desirable functions in suppressing the occurrence of yarn generation and producing processed yarn with high crimps and other properties at a higher speed than conventional methods.
すなわち、本発明の接糸体長手方向に垂直な接糸体の横
断面における凹部糸道の曲率半径は、好ましくは０．
５ｍｍ以上５０ｍｍ以下、さらに好ましくは０．８ｍｍ
以上３０ｍｍ以下、特に好ましくは１ｍｍ以」−２０ｍ
ｍ以下にするのが望ましい。That is, the radius of curvature of the recessed yarn path in the cross section of the graft of the present invention perpendicular to the longitudinal direction of the graft is preferably 0.
5 mm or more and 50 mm or less, more preferably 0.8 mm
30mm or less, particularly preferably 1mm or less"-20m
It is desirable to make it less than m.
該曲率半径が０．．５ｍｍ未満であると、加熱糸条と接

発生の原因になる。さらに、該接糸部近傍の曲率半径が
、５０＋ｎｍを越えると、糸条の加熱回転による振動を
抑えられなくなり、糸切れ、毛羽発生が多発する傾向が
出てきて、本発明の上述目的を達成しにくくなる。The radius of curvature is 0. ．． If it is less than 5 mm, the frictional force between the heated yarn and the welding surface increases due to the application of liquid, and in some cases, the rotation of the yarn causes vibration on the welding surface, causing yarn breakage and fluffing. Furthermore, if the radius of curvature near the welding portion exceeds 50+ nm, vibrations due to heating and rotation of the yarn cannot be suppressed, and yarn breakage and fluffing tend to occur frequently, thus achieving the above-mentioned object of the present invention. It becomes difficult to do.
以上、冷却用媒体の接糸部の曲率半径と、その横断面に
おける凹部糸道の曲率半径が、上述範囲に入っておれば
、該接糸部の形状に制約はなく、たとえばねじれた曲面
であってもよい。As mentioned above, as long as the radius of curvature of the welding part of the cooling medium and the radius of curvature of the recessed yarn path in its cross section are within the above ranges, there is no restriction on the shape of the welding part, for example, a twisted curved surface. There may be.
本発明において、接糸体上の加熱糸条に会１与する液体
としては、冷却効果を有するものであれば別に制限はな
いが、水を使用するのが安価で取扱いやすくて好ましい
。In the present invention, there is no particular restriction on the liquid to be applied to the heated threads on the grafted body as long as it has a cooling effect, but it is preferable to use water because it is inexpensive and easy to handle.
すなわち、加熱糸条に付与する液体は、加熱糸条の回転
でとばされ、こまかい液体の粒子となって接糸体や雰囲
気中に拡散する。したがって人体に有害な物質であれば
、雰囲気より回収する方策を講じる必要があり、仮撚加
工方法が複雑になる。That is, the liquid applied to the heated yarn is blown away by the rotation of the heated yarn, and becomes fine liquid particles that are diffused into the grafted body and the atmosphere. Therefore, if the material is harmful to the human body, it is necessary to take measures to recover it from the atmosphere, which complicates the false twisting method.
本発明においては、かかる液体を１分間あたり、好まし
くは１ ｍｌ以上１．００ ｍｌ以下、さらに好ましく
は２ｍｌ以上７０ｍｌ以下、特に好ましくは３ｍｌ以上
５０ｍｌ以下の量で一定に接糸体上の加熱糸条に付与す
ることが望ましい。In the present invention, such liquid is constantly applied to the heated thread on the grafted body in an amount of preferably 1 ml or more and 1.00 ml or less, more preferably 2 ml or more and 70 ml or less, particularly preferably 3 ml or more and 50 ml or less per minute. It is desirable to attach it to the article.
すなわち、糸条にイ（１与する液体を、１−分あたり１
ｍｌ未満の量を一定に供給しても、冷却媒体として絶対

液体が水でありかつ該液体の供給が１分間あたり１００
ｍｌを越える量を一定に供給すると、糸道面の糸条が
液体を糸条の運動力向に飛ばそうとする力を与えるため
、糸条走行の抵抗となる可能性が高くなる。したがって
、仮撚加工中に糸切れや毛羽発生が数多く起こりやすく
なる傾向が出てくるし、加工安定性が低下する。さらに
得られた仮撚加工糸の糸質も不十分なものとなる可能性
が出てくる。In other words, the amount of liquid applied to the yarn is 1 per minute.
Even if an amount of less than ml is constantly supplied, the absolute amount as a cooling medium is too small and it becomes difficult to lower the yarn temperature sufficiently.
If an amount exceeding ml is supplied at a constant rate, the yarn on the yarn path surface will apply a force that tends to blow the liquid in the direction of the movement force of the yarn, increasing the possibility that it will cause resistance to the yarn running. Therefore, there is a tendency for yarn breakage and fuzz to occur frequently during false twisting, and processing stability decreases. Furthermore, there is a possibility that the quality of the obtained false twisted yarn will be insufficient.
また、付与する液体の量を一定にしないで変化させると
、加熱糸条の振動やバルーニングが起きやすくなり、仮
撚加工中の糸切れや毛羽発生が起こりやすくなる。Furthermore, if the amount of liquid applied is not constant but is varied, vibration and ballooning of the heated yarn are likely to occur, and yarn breakage and fluffing during false twisting are likely to occur.
本発明の仮撚加工においては、高い生産性のもとに安定
に加工するためには、仮撚加工速度を好ましくは１００
０ｍ／ｍｉｎ以上、さらに好ましくは１２００ｍ／ｍｉ

0 m/min or more, more preferably 1200 m/min
It is desirable to adopt a condition of η or more, particularly preferably 1400 m/min or more.
