本発明は、伸縮性を有する複合糸の製造方法に関するも
のであり、さらに詳しくは、芯部に伸縮性を有する長繊
維糸条を用いかつ鞘部に短繊維糸条を配した伸縮性を有
する複合糸の製造方法に関するものである。Detailed Description of the Invention [Industrial Application Field] The present invention relates to a method for producing a stretchable composite yarn, and more specifically, a method for producing a stretchable composite yarn, and more specifically, The present invention relates to a method for manufacturing a stretchable composite yarn in which short fiber threads are arranged in the sheath portion.
［従来の技術］
従来、短繊維成分を芯としてこれに鞘成分を組合せて、
これら両成分の特徴を生かせしめ得る糸条として各種の
複合糸が古くから検討されてきた。[Prior art] Conventionally, a short fiber component is used as a core, and a sheath component is combined with this.
Various composite yarns have been studied for a long time as yarns that can take advantage of the characteristics of these two components.
例えばコアヤーンはその代表的なものである。また最近
、短繊維フリースの外周部に長繊維糸条を捲回せしめた
ものなども知られてきている。しかしながら、これらの
糸条の構造では、両成分が交互に出現した所謂杢糸とな
ることを避は得ない。For example, core yarn is a typical example. Also, recently, short fiber fleeces in which long fiber threads are wound around the outer periphery of the short fiber fleece have become known. However, the structure of these yarns inevitably results in so-called heathered yarns in which both components appear alternately.
加えて前者のコアヤーンの場合、両成分が撚込まれるた

場合に該伸縮性能が極めて低下し所望の伸縮性を得るこ

分を締込む形で撚回するものであるために前記コアヤー
ンと同様にやはり伸縮性を生かし得ない結果となるもの
であった。In addition, in the case of the former core yarn, both components are twisted, so even if a long fiber yarn with elasticity is used as the sheath component and the elasticity is used as a composite yarn, it will not be possible to create a composite yarn. The stretching performance is extremely reduced and it is difficult to obtain the desired elasticity.Also, in the case of the latter yarn, although the short fiber component is untwisted, the long fiber yarn itself is twisted in a way that tightens the short fiber component. Since the yarn is rotated, its stretchability cannot be utilized as in the case of the core yarn.
なおさらに、結束紡績技術を用いた複合糸も考えられる
が、結束紡績技術用による複合糸にあっては、結束繊維
による拘束力が極めて強く、やはり伸縮性を有する糸条
を一成分としてたとえ用いたとしても糸構造上の点から
伸縮性をほとんど顕在化し得ないのが実情である。Furthermore, composite yarns made using binding spinning technology are also considered, but in the case of composite yarns made using binding spinning technology, the binding force of the binding fibers is extremely strong, and it is difficult to use a composite yarn using elastic yarn as one component. Even if it were, the reality is that it is hardly possible to realize elasticity due to the thread structure.
一方、上記のような複合糸を用いてなる布帛を°考える
場合、風合と機能性の両特性はいずれも軽視することの

縮性などの緒特性を付与することなどが考えられるもの
であるが、この中で快適な衣料を実現する上で、やはり
伸縮性は特に重要な機能特性の一つである。On the other hand, when considering fabrics made using composite yarns as described above, both the texture and functionality are fundamental elements that cannot be ignored. In addition to expressing the texture of cotton well on the surface of the fabric, in terms of functionality, we are focusing on the water absorbency of cotton, as well as the elasticity, dimensional stability, lightness, quick-drying properties, and elasticity of synthetic fibers. Among these, elasticity is one of the particularly important functional properties in realizing comfortable clothing.
以上の如く、上記のような複合糸分野で伸縮性を鎖糸に
付与することは重要であるにも拘らず、またむずかしく

言えない点もあったものである。すなわち、特に単糸構
造で見ると芯部を構成する長繊維糸条は実撚を有してい
るため捲縮の発現が全く低下するのがその理由と考えら
れるものである。As mentioned above, although it is important to impart stretchability to chain yarns in the field of composite yarns as described above, it is also difficult, and the present inventors have already reported in Japanese Patent Application Laid-Open No. 58-109648. Although there are some techniques that have been proposed, these yarns cannot always be said to exhibit sufficient performance as stretchable composite yarns. That is, especially when looking at the single yarn structure, the reason is thought to be that since the long fiber yarns constituting the core have a real twist, the occurrence of crimp is completely reduced.
［発明が解決しようとする課題］
本発明の目的は、上記したような点に鑑み、芯に長繊維
糸条、鞘部に短繊維糸条を配した複合糸において両成分
の特徴を良好に保ちながら伸縮性に格段と優れた新規な
複合糸の製造方法を提供せんとするものである。[Problems to be Solved by the Invention] In view of the above-mentioned points, an object of the present invention is to provide a composite yarn in which a long fiber thread is arranged in the core and a short fiber thread is arranged in the sheath part, and the characteristics of both components are improved. The purpose of the present invention is to provide a method for producing a novel composite yarn that has significantly superior elasticity while maintaining the elasticity of the yarn.
［課題を解決するための手段］
上記した目的を達成する本発明の伸縮性を有する複合糸

特徴とする伸縮性を有する複合糸の製造方法である。[Means for Solving the Problems] The method for producing a stretchable composite yarn of the present invention that achieves the above-mentioned object is characterized in that the long fiber yarn constitutes a core portion and the short fiber yarn constitutes a sheath portion. In the method for producing a composite yarn, the long fiber yarn has the ability to expand and contract by crimping,
The staple fibers of the sheath are fed at a higher feeding speed than the long fibers of the core when being twisted together with the short fibers of the sheath. , a method for producing a stretchable composite yarn characterized by heating in a direction opposite to the first twisting direction of the long fiber yarn.
本発明の好ましい実施態様例は、以下の説明に従って順
次明らかになる。Preferred embodiments of the present invention will become apparent in the following description.
［作 用］ 以下、さらに詳しく本発明について説明をする。[Work] The present invention will be explained in more detail below.
本発明において、長繊維糸条とは、フィラメント糸であ

加工等、任意の捲縮加工を採用して得ることができ、特
に制約はされない。In the present invention, the long fiber yarn is a filament yarn, and examples of the polymer include polyethylene terephthalate, polyamide, and polybutylene terephthalate-based polymers, but are not necessarily limited to these. This long fiber yarn has the ability to expand and contract by crimping, and the long fiber yarn constitutes the core of the composite yarn of the present invention. The crimp may be structural crimp, or may be obtained by any crimp processing such as false twisting, pressing, shaping, etc., and is not particularly limited.
該長繊維糸条は、伸縮能として３０％以上５００％以下

成分である短繊維とのなじみが悪く、布帛中では毛羽立
ち、短繊維の摩耗脱落などを招き易く、また毛玉の発生
も多く好ましくないものである。The long fiber yarn preferably has an elongation ratio of 30% to 500%, more preferably 100 to 400%. If the elongation rate of the yarn is less than 30%, it is difficult to achieve good elongation properties as a fabric even if the composite yarn is made into a fabric, and if it exceeds 500%, it is difficult to achieve a good elongation rate as a fabric. Even if it can be obtained, it has poor compatibility with the short fibers, which are sheath components, and tends to cause fluffing in the fabric, abrasion of the short fibers, and shedding, and is undesirable because it often causes pilling.

伸長回復性は得られないし、また６０％を越えると短繊
維とのなじみが悪化し好ましくない。Further, the long fiber yarn preferably exhibits a stretch recovery rate of 60% or more, most preferably 70% or more. If the stretch recovery rate does not satisfy the above range, it is generally difficult to obtain a good stretch recovery rate even if the composite yarn is made into a fabric. Also,
The stretch recovery rate of the long fiber yarn is preferably from 10% to 60%, particularly preferably from 20% to 55%.
% or less. If the reading value is less than 10%, sufficient elongation recovery property cannot be obtained, and if it exceeds 60%, compatibility with short fibers deteriorates, which is not preferable.
本発明の複合糸の製造に際しては、先ず上記の長繊維糸
条に、後述する短繊維糸条との合体撚合工程で用いられ
る精紡機にて付与される加熱方向とは逆方向の撚を加え
るものであって、しかして、本発明の複合糸の製造時に
おいては撚込まれる２成分に撚数差が付与されることに
なるものである。When producing the composite yarn of the present invention, first, the above-mentioned long fiber yarn is twisted in the opposite direction to the heating direction applied by a spinning machine used in the combining and twisting process with the short fiber yarn described later. Therefore, when manufacturing the composite yarn of the present invention, a difference in the number of twists is imparted to the two components to be twisted.
かかる撚数差は長繊維糸条に付与された撚数と精紡機の
設定撚数で定まるものである。This difference in the number of twists is determined by the number of twists imparted to the long fiber yarn and the number of twists set on the spinning machine.
そして、ここにおいて複合糸として最も大きな伸縮性能
を発揮せしめ得るのは芯部糸条が実質的に無撚状態で配
置するときであって、すなわち、複合糸を構成する芯部
成分と鞘成分の単位長さ当りの撚数をそれぞれＴｃ、Ｔ

８５倍を越えるときには、複合糸として極端に伸縮性能
が低下し好ましくないものである。以上の知見により、
Ｔｃの好ましい範囲は、
０≦Ｔｃ≦０．８５・Ｔｓ
で表わされる範囲である。Here, the greatest stretching performance as a composite yarn can be exhibited when the core yarn is arranged in a substantially untwisted state, that is, when the core component and sheath component that make up the composite yarn are arranged in a substantially untwisted state. The number of twists per unit length is Tc and T, respectively.
If it is assumed to be s, then this is substantially when Tc=0. Furthermore, according to the findings of the present inventors, even if the number of twists in the core yarn is below a certain level, it is possible to exhibit preferable stretch performance, and specifically, the number of twists in the core yarn is T.C.
When the number of twists of the sheath component is 0.85 times or less than Ts, preferable stretching performance can be exhibited. The value of Tc is 0.0 of the value of Ts.
When it exceeds 85 times, the stretching performance of the composite yarn is extremely reduced, which is not preferable. Based on the above knowledge,
A preferable range of Tc is 0≦Tc≦0.85·Ts.
かかる点について、さらに具体的に説明すると、例えば
芯成分のフィラメント糸条に予め８００Ｔ／ｍのＳ撚を

きるものである。To explain this point more specifically, for example, the core component filament yarn is given an S twist of 800 T/m in advance, and the short fiber fleece that is the sheath component and the filament yarn are combined and twisted. When combining, the number of twists is 8007/
By heating in the twisting direction 2, Tc=
It is possible to obtain a composite yarn having particularly good stretchability of 0.0.
なお、ただし厳密に言うならば、フィラメント芯成分と

糸製造の際に解撚を伴うものであるために該フィラメン

干の撚戻り長さ増加率を考慮に入れておくのがよいもの
である。However, strictly speaking, when setting the feed rate of the filament core component and short fiber sheath component and the heating number of the pre-twisted filament yarn, it is necessary to set the feed rate of the filament core component and short fiber sheath component as well as the number of heating times for the pre-twisted filament yarn. Since the filament core component is a filament core component, there is untwisting due to untwisting, and it is good to take into consideration the slight increase rate in length due to untwisting.
本発明によって得られる複合糸は、前記の如くの芯成分
が実質的に無撚、鞘成分が有撚という構造をとるのが最

撚される場合の２種の態様があるものであり、本発明で
はいずれであってもよい。It is most desirable for the composite yarn obtained by the present invention to have a structure in which the core component is substantially untwisted and the sheath component is twisted, but even if the core component is twisted, the above-mentioned Tc
, Ts, the desired effect can be obtained, and the pre-twisted filament core component has two types: under-untwisting and over-untwisting. There are various embodiments, and the present invention may adopt any of them.
また、本発明によって得られる複合糸の伸縮性能は、鞘
成分の撚状態によっても左右され、本発明者らの知見に
よれば、良好な伸縮性能を発揮するために該鞘部成分の
撚係数Ｋが、１．５以上で５．０以下であることが必要
であり、より好ましくは、Ｋ＝２．８〜３．５の範囲内
である。すなわち、上記の撚係数Ｋが１．５未満である
と鞘部成分の芯成分への巻付き性が不良になり糸切れや
欠点糸を作ってしまい好ましくない。また、撚係数Ｋが
５．０よりも大きな値になると鞘部成分の撚による芯成
分への締付は力が犬となり伸縮性能が著しく低下するも
のである。In addition, the stretch performance of the composite yarn obtained by the present invention also depends on the twist state of the sheath component, and according to the findings of the present inventors, in order to exhibit good stretch performance, the twist coefficient of the sheath component is It is necessary that K is 1.5 or more and 5.0 or less, and more preferably K is in the range of 2.8 to 3.5. That is, if the above-mentioned twist coefficient K is less than 1.5, the windability of the sheath component around the core component becomes poor, resulting in yarn breakage and defective yarns, which is not preferable. Furthermore, when the twist coefficient K is larger than 5.0, the force of tightening the core component due to the twisting of the sheath component becomes too strong, and the elastic performance is significantly reduced.
また、さらに芯部を構成する伸縮能を有する長繊維糸条
の性能も複合糸の伸縮性能を左右する重要な要因の一つ
である。Furthermore, the performance of the long fiber yarn having stretchability that constitutes the core is also one of the important factors that influences the stretchability of the composite yarn.
すなわち、本発明者らの知見によれば、該長繊維糸条の
糸繊度としては５〜３００デニールであることが必要で
あり、かかる範囲内から所望の布帛特性に応じて芯部を
なす長繊維糸条の繊度を適宜選択するとよいものである
。That is, according to the findings of the present inventors, the yarn fineness of the long fiber yarn needs to be 5 to 300 deniers, and the length forming the core can be adjusted from within this range depending on the desired fabric properties. It is preferable to appropriately select the fineness of the fiber yarn.
またなお、本発明において、該長繊維糸条に関して「伸
縮能を有する」とはＣＲ（伸縮復元率）値が１０％以上
であるものを言うものである。かかるＣＲ値が１０％未
満であると良好な伸縮性能を有する複合糸を得ることは
到底不可能である。Furthermore, in the present invention, the expression "having stretchability" with respect to the long fiber yarn means that the CR (stretch recovery rate) value is 10% or more. If the CR value is less than 10%, it is impossible to obtain a composite yarn with good stretch performance.
そして、本発明で言う伸縮能は、前述の如く熱可塑性合

得られるものであって、所謂捲縮に依存する伸縮特性を
言い、ポリウレタン糸のような所謂弾性糸は含まないも
のである。As mentioned above, the elasticity referred to in the present invention is obtained by subjecting thermoplastic synthetic fibers to various crimping processes such as false twisting, folding, and shaping, or by structural crimping. This refers to the so-called elasticity dependent on crimp, and does not include so-called elastic yarns such as polyurethane yarns.
本発明において、芯部成分／鞘部成分の構成重量比率は

る結果となり好ましくなく、本発明者らの知見によれば
、好ましくは（８０〜５０）％／（２０〜５０）％であ
る。In the present invention, the constituent weight ratio of core component/sheath component is preferably within the range of (95-5)%/(5-95)%. Regarding this, based on the sheath component, if the ratio of the sheath component is less than 5%, the advantages of the short fiber component will not be realized, and if it exceeds 95%, the elasticity will be inhibited, which is not desirable. , according to the findings of the present inventors, is preferably (80-50)%/(20-50)%.
上記の複合糸は、製編織されて編織物にされたり、ある
いは積層されて不織布などにされて、布帛化される。The above-mentioned composite yarns are knitted and woven into a knitted fabric, or laminated to form a nonwoven fabric or the like to be made into a fabric.
