【発明の詳細な説明】 (産業上の利用分野) 本発明は、マルチフィラメント糸条からなり。[Detailed description of the invention] (Industrial application field) The present invention consists of a multifilament yarn.
スパン調の風合を有するとともに、集束性に優れた部分
嵩高系の製造方法に関するものである。The present invention relates to a method for manufacturing a partially bulky system that has a span-like texture and excellent cohesiveness.
(従来の技術)
従来、マルチフィラメント糸条にスパン調の風合を付与

する方法がよく知られているが。(Prior Art) Conventionally, as a method of imparting a spun-like texture to multifilament yarns, a method of forming a slab system using false twisting is well known.
この方法で形成されたスラブ糸は集束性が悪いので後工
程の通過性に難点があり、加工性や品位の低下等、実用
上の問題が発生しやすいという欠点があった。The slub yarn formed by this method has poor cohesiveness, making it difficult to pass through post-processing, and has the disadvantage that practical problems such as deterioration in workability and quality are likely to occur.
一方、特開昭60−2737号公報には、旋回流と攪乱
流を付与し得る単一の流体処理装置を用いて。On the other hand, Japanese Patent Application Laid-Open No. 60-2737 uses a single fluid processing device that can provide swirling flow and turbulent flow.

いう欠点があった。A method has been proposed in which a slub yarn is formed by falsely twisting the yarn using a swirling flow, and then the slub yarn is entangled using a turbulent flow. This method performs interlace interlacing, so although it has the effect of converging and blending yarns, it has the disadvantage that loop fuzz is not formed on the yarn surface, so it lacks a sense of fullness and warmth.

用に影響を及ぼし。Japanese Patent Laid-Open No. 63 (1982) described a method for manufacturing slub yarn in which loop fluff is formed on the yarn using a fluid jet nozzle equipped with swirling flow and propulsive force.
This was proposed in Publication No.-256742. However, in this method, the false twisting action of the swirling flow and the disturbance action of the propelling flow are simultaneously applied inside the fluid injection nozzle, so subtle tension fluctuations in the slab and non-slab parts that occur during winding are caused by the fluid. affect the action.
このため、推進流による攪乱作用が乱れて、糸条の長手
方向における交絡とループ毛羽形成に微妙な差が生じ、
交絡とループ毛羽が不均一に形成されやすいという欠点
があった。For this reason, the disturbance effect caused by the propelling flow is disrupted, causing subtle differences in entanglement and loop fuzz formation in the longitudinal direction of the yarn.
There was a drawback that entanglement and loop fluff were likely to be formed unevenly.

In addition, by forming uniform entanglement and loop fluff throughout the yarn, the slub shape is clear even when it is made into a fabric, giving the fabric a varied appearance and a soft, warm texture similar to that of a span. The technical objective is to provide a method for producing partially bulky yarns that can be manufactured using the following methods.

した。(Means for Solving the Problems) As a result of intensive studies to solve the above problems, the inventors of the present invention have developed a swirl flow nozzle for false twisting yarns and a jet nozzle for imparting entanglement and loop fuzz to yarns. (jet fluid agitation nozzle) is used separately, and the winding of the swirling flow nozzle is done so that fluctuations in the tension of the yarn due to the action do not affect the jet nozzle, so that the entire yarn is uniformly wound. The present invention was achieved by discovering that entanglement and loop fluff can be formed.

Then, the sheath yarn is wound around the core yarn in multiple layers to form at least 2 partial bulky parts/m in the longitudinal direction of the yarn, and then the 9 yarns are passed through a guide to a jet nozzle. supply.
交絡とループ毛羽を形成させることを特徴とする部分嵩
高糸の製造方法を要旨とするものである。The gist of the present invention is a method for producing a partially bulky yarn characterized by forming entanglement and loop fuzz.
以下1本発明の詳細な説明する。Hereinafter, one aspect of the present invention will be explained in detail.
第1図は9本発明の一実施態様を示す概略工程図である
。第1図において、芯糸1は、供給ローラ4から一定の
過供給率で旋回流ノズル8に供給され、旋回流ノズル8
の旋回流によって加熱されながら、ガイド11を介して
ジェットノズル9に供給される。FIG. 1 is a schematic process diagram showing one embodiment of the present invention. In FIG. 1, the core yarn 1 is supplied from the supply roller 4 to the swirl flow nozzle 8 at a constant overfeed rate.
The water is supplied to the jet nozzle 9 via the guide 11 while being heated by the swirling flow of the water.
一方、鞘糸2は、供給ローラ5により芯糸1の供給量よ
り大なる過供給率で供給され、給糸ガイド10を経て芯
糸1の加撚域で芯糸1に合糸される。On the other hand, the sheath yarn 2 is supplied by the supply roller 5 at an excess supply rate that is greater than the supply amount of the core yarn 1, passes through the yarn feeding guide 10, and is combined with the core yarn 1 in the twisting region of the core yarn 1.
芯糸1の加熱作用により鞘糸2は芯糸1に捲回されるが
、捲回されるにつれて鞘糸2の張力が増加し1合糸点1
2が供給ローラ4側12′に移動する。The sheath yarn 2 is wound around the core yarn 1 due to the heating action of the core yarn 1, but as it is wound, the tension of the sheath yarn 2 increases and the sheath yarn 2 is wound at the doubling point 1.
2 moves to the supply roller 4 side 12'.
次いで、鞘糸2の張力がある限界まで増大すると、安定
な撚状態に戻ろうとして合糸点12′が逆方向、つまり
旋回流ノズル8側の12に移動するので、張力が減少す
る。さらに加熱作用が続くと。Next, when the tension of the sheath yarn 2 increases to a certain limit, the yarn joining point 12' moves in the opposite direction, that is, to 12 on the swirl flow nozzle 8 side, in an attempt to return to a stable twisted state, so that the tension decreases. If the heating effect continues.
再び鞘糸2の張力が増加して合糸点が12′に移動する
。このような合糸点の往復運動により、芯糸1に鞘糸2
が複数の層状に捲回した部分嵩高部が糸条の長手方向に
間歇的に形成されることになる。The tension of the sheath yarn 2 increases again and the doubling point moves to 12'. Due to this reciprocating movement of the yarn joining point, the sheath yarn 2 is attached to the core yarn 1.
The partial bulky portions are formed intermittently in the longitudinal direction of the yarn by winding the yarn into a plurality of layers.
上記合糸点の移動距離は、旋回流ノズル8の旋回力、給
糸ガイド10の位置等にもよるが1通常3〜10cmと
なるように設定するのが好ましい。The moving distance of the yarn doubling point is preferably set to usually 3 to 10 cm, although it depends on the swirling force of the swirl nozzle 8, the position of the yarn feeding guide 10, etc.
次に、旋回流ノズル8で部分嵩高部を形成した糸条は、
旋回流ノズル8とジェットノズル9間に設けたガイド1

ベリローラ6を経て捲取パッケージ7に捲取られる。Next, the yarn with the partially bulky part formed by the swirl flow nozzle 8 is
Guide 1 provided between swirl flow nozzle 8 and jet nozzle 9
1 to the jet nozzle 9, and after being caused to form entanglement and loop fluff by the disturbance action of the jet nozzle 9, it is passed through the delivery roller 6 and wound up into the winding package 7.

用で生じる糸条の微妙な張力変動を緩和吸収し、ジェッ
トノズル9に導かれる糸条の張力を一定に保つ役割をす
る。したがって、ガイド11は。At this time, the guide 11 serves to moderate and absorb subtle tension fluctuations in the yarn caused by the winding action of the swirl flow nozzle 8, and to keep the tension of the yarn guided to the jet nozzle 9 constant. Therefore, the guide 11.
糸案内的な要素と張力変動を緩和吸収する抵抗体的な要
素が要求され、これらを勘案して、ガイドの材質、形状
あるいは表面仕上げ等を適宜選定することが必要であり
1例えば、梨地加工されたガイドより摩擦抵抗が大きな
アルミナ製のガイドが好ましい。また、このガイド11
を利用して糸道を屈曲させれば、よりその効果を高める
ことが可能となる。A thread-guiding element and a resistor-like element to moderate and absorb tension fluctuations are required, and it is necessary to take these into consideration when selecting the material, shape, surface finish, etc. of the guide as appropriate. It is preferable to use an alumina guide, which has a higher frictional resistance than a steel guide. Also, this guide 11
If the thread path is bent by using this, the effect can be further enhanced.
次に、このガイド11を経た糸条は、一定の張力を保ち
ながらジェットノズル9内に導かれ、ジェットノズル9
の流体撹乱作用で均一な交絡とループ毛羽が形成される
。ここで、ジェットノズル9内に導かれた糸条は、流体
噴射流による撹乱作用を受け、芯糸と鞘糸が開繊された
状態となるが。Next, the yarn passing through this guide 11 is guided into the jet nozzle 9 while maintaining a constant tension, and the yarn is guided into the jet nozzle 9 while maintaining a constant tension.
Uniform entanglement and loop fluff are formed by the fluid disturbance effect. Here, the yarn guided into the jet nozzle 9 is subjected to a disturbance effect by the fluid jet flow, and the core yarn and sheath yarn are in an opened state.
芯糸に鞘糸が複数の層状に捲回した部分嵩高部はこのよ
うな開繊作用を受けても、その複雑な捲回により、外層
部または層状の一部が開繊されるものの、内層部は捲回
した状態で残ることになる。Even if the bulky part where the sheath yarn is wound in multiple layers around the core yarn is subjected to such opening action, due to the complicated winding, the outer layer or a part of the layer will be opened, but the inner layer will not be opened. The section will remain rolled up.
このため1部分嵩高部、非嵩高部とも、この開繊部分が
交絡するとともに、ループ毛羽を形成し得るのである。Therefore, in both the partially bulky portion and the non-bulky portion, the spread portions become intertwined and can form loop fuzz.

、非嵩高部ともに交絡とループ毛羽を形成させるために
は、芯糸の加熱張力が低い状態で鞘糸をゆるやかに捲回
させることが可能な旋回流ノズルを使用する必要がある
。As mentioned above, in order to perform fluid agitation treatment on a yarn having a partially bulky part in which sheath yarns are wound in multiple layers around a core yarn, to form entanglement and loop fluff in both the partially bulky part and the non-bulky part. , it is necessary to use a swirl flow nozzle that can gently wind the sheath yarn while the heating tension of the core yarn is low.
なお1部分嵩高部の大きさ及び頻度等は、所望に応じて
変更することが可能であり1例えば、旋回ノズルの旋回
力、糸条の過供給率あるいはガイド10と芯糸間の距離
等を適宜変更して調整することができる。The size and frequency of the 1-part bulky portion can be changed as desired.1 For example, the turning force of the turning nozzle, the yarn overfeed rate, the distance between the guide 10 and the core yarn, etc. It can be changed and adjusted as appropriate.
また、芯糸の過供給率は2〜10%、鞘糸の過供給率は
、芯糸より5%以上、特に10〜40%大きくするのが
好ましい。Further, it is preferable that the oversupply rate of the core yarn is 2 to 10%, and the oversupply rate of the sheath yarn is 5% or more, particularly 10 to 40% higher than the core yarn.

であれば特に限定されるものではない。The swirling flow nozzle used in the present invention is not particularly limited, and any type can be used as long as it can false-twist the yarn, preferably 200 T/M or more, particularly 5007/M or more. An air swirl nozzle that can impart swirl under low tension is desirable. Jet nozzles can also form entanglements and loop fuzz in the yarn. It is not particularly limited as long as it is a so-called taslan processing nozzle.
本発明で得られる部分嵩高系は、第2図に示すように、
糸条の長手方向に部分嵩高部Aと非嵩高部Bとを交互に
有し1部分嵩高部Aは、芯糸1に鞘糸2が複数の層状に
