本発明の多層構造紡績糸は、糸構造及び獣毛繊維の混率の最適化を図り、生地の摩擦強力、緯伸び及び抗ピリング性を向上した多層構造紡績糸、その製造方法、生地及び衣服を提供できる。これらの特性は、ビジネス用スーツ、ビジネス用ユニホーム、学生服などに好適である。本発明の多層構造紡績糸の製造方法は、結束紡績法であるため、リング紡績法に比べて約１０～２０倍の高速で紡績でき、効率よく合理的に、コストも安く製造できる。また、毛羽数が少なく均整な糸であり、熱水収縮率も高い多層構造紡績糸を提供する The multi-layered spun yarn of the present invention is a multi-layered spun yarn with improved frictional strength, weft elongation and anti-pilling properties of the fabric by optimizing the yarn structure and the blend ratio of animal hair fibers, its production method, fabric and clothing. can provide.

本発明の多層構造紡績糸は、芯成分繊維と鞘成分繊維で構成され、前記鞘成分繊維は内層繊維と表層繊維を含む３層構造になっている。この糸構造により、糸構造は強固となり、生地の摩擦強力及び抗ピリング性を向上できる。またこの糸構造により、後の工程で多層構造紡績糸又は生地を熱水収縮させても、芯成分繊維の伸縮性マルチフィラメント糸が外に飛び出さず、スナールになりにくい。 The multi-layered spun yarn of the present invention is composed of a core component fiber and a sheath component fiber, and the sheath component fiber has a three-layer structure including an inner layer fiber and a surface layer fiber. With this yarn structure, the yarn structure becomes strong, and the frictional strength and anti-pilling properties of the fabric can be improved. In addition, due to this yarn structure, even if the multi-layered spun yarn or fabric is shrunk in hot water in a later step, the stretchable multifilament yarn of the core component fiber does not jump out and is less prone to snarling.

芯成分繊維は伸縮性マルチフィラメント糸である。伸縮性マルチフィラメント糸は、コンジュゲートマルチフィラメント糸又は仮撚マルチフィラメント糸が好ましい。これにより、生地の緯伸びを向上できる。コンジュゲートマルチフィラメント糸は、一例として、ポリエチレンテレフタレート（ＰＥＴ）とポリトリメチレンテレフタレート（ＰＴＴ）がサイドバイサイドで複合紡糸されたポリエステルコンジュゲートフィラメント糸が好ましい。このような伸縮糸は例えば、商品名“ライクラＴ４００ファイバー”（東レ・オペロンテックス社販売）がある。別の伸縮糸としては、極限粘度の異なる２成分のポリエチレンテレフタレートのコンジュゲート糸、ＰＥＴとポリブチレンテレフタレート（ＰＢＴ）とのコンジュゲート糸、ＰＴＴとＰＢＴとのコンジュゲート糸なども使用できる。このようなポリエステルコンジュゲートフィラメント糸は、ＰＥＴマルチフィラメント糸と同様に耐塩素性も耐光性も高い。コンジュゲートマルチフィラメント糸は染色温度程度の熱水処理により捲縮が発現し、伸縮性(ストレッチ性)が発現する。このことから潜在捲縮糸ともいわれている。 The core component fibers are elastic multifilament yarns. The stretchable multifilament yarns are preferably conjugated multifilament yarns or false twisted multifilament yarns. Thereby, the weft elongation of the fabric can be improved. The conjugate multifilament yarn is, for example, preferably a polyester conjugate filament yarn in which polyethylene terephthalate (PET) and polytrimethylene terephthalate (PTT) are conjugate-spun side-by-side. Such a stretchable yarn is, for example, the product name "Lycra T400 Fiber" (sold by Toray Operontex Co.). Other stretch yarns that can be used include two-component polyethylene terephthalate conjugate yarns with different intrinsic viscosities, PET and polybutylene terephthalate (PBT) conjugate yarns, and PTT and PBT conjugate yarns. Such polyester conjugate filament yarns are highly chlorine and lightfast as are PET multifilament yarns. The conjugated multifilament yarn develops crimps by hot water treatment at about the dyeing temperature, and develops elasticity (stretchability). For this reason, it is also called a latent crimped yarn.

仮撚マルチフィラメント糸は、ポリエステル仮撚マルチフィラメント糸、ナイロン仮撚マルチフィラメント糸、セルロースアセテート仮撚マルチフィラメント糸、キュプラ仮撚マルチフィラメント糸、シルク仮撚マルチフィラメント糸などが好ましい。これらの糸は獣毛繊維と組み合わせるとより高付加価値の交撚糸となる。なかでもポリエチレンテレフタレートマルチフィラメント仮撚糸は強度も高く腰もあることから好ましい。 The false-twisted multifilament yarn is preferably a polyester false-twisted multifilament yarn, a nylon false-twisted multifilament yarn, a cellulose acetate false-twisted multifilament yarn, a cupra false-twisted multifilament yarn, a silk false-twisted multifilament yarn, or the like. When these yarns are combined with animal hair fibers, they become high-value-added cross-twisted yarns. Among them, polyethylene terephthalate multifilament false-twisted yarn is preferable because of its high strength and stiffness.

鞘成分繊維は獣毛繊維と獣毛繊維以外の短繊維を含む混紡繊維で構成される。鞘成分繊維は、内層に位置する短繊維が無撚り状であり、表層に位置する短繊維が一方向に実撚り状に巻き付いて全体を束ねている。内層の無撚り状短繊維と、表層に位置する実撚り状繊維は、別の繊維であってもよいし、同一繊維がマイグレーションにより入れ替わっていてもよい。 Sheath component fibers are composed of blended fibers containing animal hair fibers and short fibers other than animal hair fibers. In the sheath component fiber, the short fibers located in the inner layer are untwisted, and the short fibers located in the surface layer are wound in one direction in a real twist to bind the whole. The non-twisted short fibers in the inner layer and the real-twisted fibers in the surface layer may be different fibers, or the same fibers may be replaced by migration.

獣毛繊維は、羊の毛であるウール（メリノ・ウールの場合、繊維長３０～１５０ｍｍ）、山羊の毛であるモヘヤ（繊維長１００～３００ｍｍ）、カシミヤ（繊維長４０～９０ｍｍ）ラクダの毛であるキャメル（繊維長５０～７０ｍｍ）、アルパカ（繊維長１００～２００ｍｍ）、ビキューナ（繊維長２０～７０ｍｍ）、ウサギの毛であるアンゴララビット（繊維長１００～１３０ｍｍ）等を使用できる。このうち好ましいのは最も汎用性があるウールである。ウールと他の獣毛繊維とを混紡してもよい。獣毛繊維の平均繊維長は２０～３５ｍｍにカットするのが好ましい。多層構造紡績糸を１００質量％としたとき、獣毛繊維の混率は５～５０質量％である。好ましい獣毛繊維の混率は７～４５質量％であり、より好ましくは１０～４０質量％である。これにより、風合いが良く、温かい織物、編み物が得られる。 Animal hair fibers include sheep's wool (fiber length 30-150 mm in the case of merino wool), goat hair mohair (fiber length 100-300 mm), cashmere (fiber length 40-90 mm), and camel hair. Camel (fiber length 50-70 mm), Alpaca (fiber length 100-200 mm), Vicuna (fiber length 20-70 mm), Angora rabbit (fiber length 100-130 mm), etc. can be used. Among these, wool is preferred because it is the most versatile. Wool and other animal hair fibers may be blended. The average fiber length of the animal hair fibers is preferably cut to 20 to 35 mm. When the multi-layer structure spun yarn is taken as 100% by mass, the mixing ratio of animal hair fibers is 5 to 50% by mass. The blending ratio of animal hair fibers is preferably 7 to 45% by mass, more preferably 10 to 40% by mass. As a result, woven fabrics and knitted fabrics with good texture and warmth can be obtained.

鞘成分繊維は、獣毛繊維と獣毛繊維以外の短繊維を混紡する。獣毛繊維以外の短繊維は、合成繊維、再生繊維、天然繊維のいずれかでもよい。好ましくはポリエステル短繊維、ナイロン短繊維、セルロースアセテート短繊維、キュプラ短繊維、シルク短繊維、コットン繊維、麻繊維、レーヨン繊維などである。この中でもポリエステル短繊維は強度高く腰もあることから好ましい。獣毛繊維以外の短繊維の平均繊維長は２０～５１ｍｍにカットするのが好ましい。 Sheath component fibers are made by blending animal hair fibers and short fibers other than animal hair fibers. Short fibers other than animal hair fibers may be synthetic fibers, regenerated fibers, or natural fibers. Polyester staple fibers, nylon staple fibers, cellulose acetate staple fibers, cupra staple fibers, silk staple fibers, cotton fibers, hemp fibers, rayon fibers and the like are preferred. Among these fibers, polyester staple fibers are preferred because of their high strength and stiffness. Short fibers other than animal hair fibers are preferably cut to have an average fiber length of 20 to 51 mm.

多層構造紡績糸を１００質量％としたとき、芯成分繊維の伸縮性マルチフィラメント糸は１０～４０質量％であり、鞘成分繊維は６０～９０質量％が好ましい。より好ましくは、芯成分繊維の伸縮性マルチフィラメント糸は１５～３５質量％、鞘成分繊維は６５～８５質量％であり、さらに好ましくは、芯成分繊維の伸縮性マルチフィラメント糸は２０～３０質量％、鞘成分繊維は７０～８０質量％である。 When the multilayer structure spun yarn is 100% by mass, the elastic multifilament yarn of the core component fiber is preferably 10 to 40% by mass, and the sheath component fiber is preferably 60 to 90% by mass. More preferably, the elastic multifilament yarn of the core component fiber is 15 to 35% by mass, and the sheath component fiber is 65 to 85% by mass, and even more preferably, the elastic multifilament yarn of the core component fiber is 20 to 30% by mass. %, and the sheath component fiber is 70-80% by mass.

本発明の多層構造紡績糸は、生産性に優れることから結束紡績糸が好ましい。リング紡績糸に比べて結束紡績糸は、約１０～２０倍生産性に優れる。とくに旋回流ノズルが１個の結束紡績装置により得られた結束紡績糸は毛羽も少なく、糸構造は強固となり、生地の摩擦強力及び抗ピリング性を向上できる。なお、結束紡績は、ボルテックス(VORTEX)紡績ともいう。 The multi-layered spun yarn of the present invention is preferably a bundled spun yarn because of its excellent productivity. Tie spun yarn is about 10 to 20 times more productive than ring spun yarn. In particular, the spun bundled yarn obtained by a binding spinning device having one swirl flow nozzle has less fuzz, a strong yarn structure, and improved frictional strength and anti-pilling properties of the fabric. The bundle spinning is also called VORTEX spinning.

本発明の多層構造紡績糸は、メートル番手（単糸）で、２０～５２番（繊度：５００～１９２decitex）の範囲が好ましい。この範囲であれば、ビジネス用スーツ、ビジネス用ユニホーム、学生服などに好適である。多層構造紡績糸は２本撚り合わされた双糸としてもよい。前記双糸のメートル番手は１０～２６番（繊度：１０００～３８４decitex）が好ましい。双糸にすると、生地の表面がきれいになるうえ、織物の強度も高くなる。 The multi-layer structure spun yarn of the present invention preferably has a metric count (single yarn) in the range of 20 to 52 (fineness: 500 to 192 decitex). This range is suitable for business suits, business uniforms, school uniforms, and the like. The multilayer structure spun yarn may be a two-ply yarn in which two yarns are twisted together. The metric count of the two-ply yarn is preferably 10 to 26 (fineness: 1000 to 384 decitex). Two-ply yarn not only makes the surface of the fabric clean, but also increases the strength of the fabric.

本発明の織物又は編み物の単位面積あたりの質量（目付）は５０～４００ｇ／ｍ２の範囲が好ましい。前記範囲であれば、さらに軽くて着心地の良い衣服とすることができる。さらに好ましくは１００～３５０ｇ／ｍ２の範囲、とくに好ましくは１５０～３００ｇ／ｍ２の範囲である。織物組織は、平織り、綾織り、朱子織、その他の変化織など、どのような組織であってもよい。編み物は、横編み、丸編み、経編などであり、編み物組織はどのような組織であってもよい。 The weight per unit area (basis weight) of the woven fabric or knitted fabric of the present invention is preferably in the range of 50 to 400 g/m 2 . If it is the said range, it can be set as lighter and more comfortable clothes. It is more preferably in the range of 100-350 g/m 2 , particularly preferably in the range of 150-300 g/m 2 . The woven fabric may be any weave such as plain weave, twill weave, satin weave, and other variation weaves. Knitting includes weft knitting, circular knitting, warp knitting, and the like, and any knitting structure may be used.

本発明の製造方法に使用する紡績機は、例えば村田機械社製、商品名”MURATA VORTEX SPINNER”として販売されている。特徴的なことは、糸速度が３００～４５０ｍ／分であり、リング紡績機の約１０～２０倍生産速度が速いことである。 Next, the apparatus and method for producing the core-sheath structure yarn of the present invention will be described with reference to the drawings. In the following drawings, the same symbols indicate the same items. FIG. 1 is a perspective view showing the essential parts of a binding spinning device 1 according to one embodiment of the present invention.
(1) Draft process The draft zone 6 of the binding spinning device 1 is composed of a pair of front rollers 2, 2', a pair of second rollers 3 having an apron, a pair of third rollers 4, and a pair of back rollers 5. ing. A sliver 7 obtained by blending animal hair fibers to be a sheath component fiber and short fibers of an animal hair fiber template is passed through a sliver guide 8, supplied from a back roller 5, and drafted in a draft zone 6. - 特許庁
(2) Combining Core Component Fiber and Coating Component Fiber In front of the front rollers 2 and 2' (upstream side) of the draft zone 6, an elastic multifilament yarn 9 as a core component fiber is supplied, and the sliver 7 is drafted. Combine with the fiber bundles that have been formed.
(3) Spun Yarn Forming Process A fiber bundle of the combined core component fiber yarn and sheath component fiber is supplied to the spindle 10 arranged away from the discharge part of the front rollers 2, 2', and false twisted by a swirling flow. to obtain a multi-layered structure spun yarn 11.
(4) Winding process The obtained multi-layered structure spun yarn 11 passes through the slab catcher 12, is taken up by the friction roller 13, is driven by the winding drum 14 of the winding section 17, and is supported by the cradle arm 15 as a package. 16 is wound up.
The spinning machine used in the manufacturing method of the present invention is sold under the trade name "MURATA VORTEX SPINNER" manufactured by Murata Machinery Co., Ltd., for example. Characteristically, the yarn speed is 300-450 m/min, which is about 10-20 times faster than the ring spinning machine.

本発明の一例の多層構造紡績糸（結束紡績糸）２０を図２に示す。この例は、多層構造紡績糸を１００質量％としたとき、ウールの混率を１５質量％とした例である。芯成分繊維２１が伸縮性マルチフィラメント糸であり、鞘成分繊維２４はウールとポリエステル（ＰＥＴ）短繊維の混紡繊維である。ウールは内層繊維２２に多く存在し、無撚り状態である。ＰＥＴ短繊維は表層の巻き付き繊維２３に多く存在している。表層の巻き付き繊維２３は一方向に撚りが掛けられた実撚り状であり、全体を束ねている。これにより、毛羽やたるみは少なく、摩耗を受けても繊維が脱落せず、強固な糸状態を保つ。前記において一方向とは、Ｓ撚りの巻き付け繊維又はＺ撚りの巻き付け繊維のことをいい、撚り角が同一ということではない。Ｓ撚りの巻き付け繊維又はＺ撚りの巻き付け繊維は、結束紡績機のスピナーの圧空旋回流の方向によって決まる。この多層構造紡績糸（結束紡績糸）２０は、芯成分繊維２１と、鞘成分繊維２４のうちの無撚りの内層繊維２２と、表層の巻き付き繊維２３の３層構造になっている。この糸構造により、糸強度は高いものとなる。また、内層のウールは表層のＰＥＴ短繊維に被覆保護されていることにより、ウールの傷みは防止される。 FIG. 2 shows a multi-layer structure spun yarn (bundle spun yarn) 20 as an example of the present invention. This example is an example in which the blend ratio of wool is 15% by mass when the multi-layer structure spun yarn is 100% by mass. The core component fiber 21 is an elastic multifilament yarn, and the sheath component fiber 24 is a blended fiber of wool and polyester (PET) short fibers. A large amount of wool exists in the inner layer fibers 22 and is in a non-twisted state. Many PET short fibers are present in the wound fibers 23 of the surface layer. The wound fibers 23 of the surface layer are in a real-twisted shape, twisted in one direction, and bundle the whole. As a result, there is little fluff or slack, and even if it is worn, the fibers do not come off and maintain a strong yarn state. In the above description, "one direction" refers to S-twisted fibers or Z-twisted fibers, and does not mean that the twist angles are the same. S-twist wound fibers or Z-twist wound fibers are determined by the direction of the pneumatic swirl flow of the spinner of the tie spinner. This multi-layer structure spun yarn (bundle spun yarn) 20 has a three-layer structure of a core component fiber 21, an untwisted inner layer fiber 22 of sheath component fibers 24, and a wound fiber 23 of a surface layer. Due to this yarn structure, the yarn strength is high. In addition, since the wool in the inner layer is covered and protected by the short PET fibers in the surface layer, the wool is prevented from being damaged.

本発明の別の例の多層構造紡績糸（結束紡績糸）２５を図３に示す。この例は、多層構造紡績糸２５を１００質量％としたとき、ウールの混率を３５質量％とした例である。図２と異なるのは、鞘成分繊維２８の内層繊維２６も表層の巻き付き繊維２７も、ウールとＰＥＴ短繊維の混紡繊維の状態で内層繊維２２と表層の巻き付き繊維２３となっていることである。２６ｂは内層のウール，２６ａは内層のＰＥＴ短繊維、２７ｂは表層のウール、２７ａは表層のＰＥＴ短繊維である。この多層構造紡績糸も３層構造になっていることから、糸強度は高いものとなる。また、表層の巻き付き繊維は、ウールとＰＥＴ短繊維がしっかりと絡んでいるため、ウールの傷みは防止される。 FIG. 3 shows a multi-layer structure spun yarn (bundle spun yarn) 25 of another example of the present invention. In this example, when the multi-layer structure spun yarn 25 is 100% by mass, the blend ratio of wool is 35% by mass. The difference from FIG. 2 is that both the inner layer fiber 26 and the surface layer wound fiber 27 of the sheath component fiber 28 are the inner layer fiber 22 and the surface layer wound fiber 23 in the state of a blended fiber of wool and PET short fibers. . 26b is inner layer wool, 26a is inner layer PET short fibers, 27b is surface layer wool, and 27a is surface layer PET short fibers. Since this multi-layer structure spun yarn also has a three-layer structure, the yarn strength is high. In addition, since the wound fibers in the surface layer are tightly entwined with the wool and the PET short fibers, the wool is prevented from being damaged.

図５は本発明の別の実施形態における芯鞘構造紡績糸の側面写真(倍率２００倍)であり、多層構造紡績糸を１００質量％としたとき、ウールの混率を３５質量％とした例である。
図２～図５から総じていえることは、表層の巻き付き繊維が、芯成分繊維及び鞘成分の内層繊維を強固にラッピングしており、これが生地の摩擦強力、緯伸び及び抗ピリング性の向上に寄与しているといえる。 FIG. 4 is a side view photograph (magnification of 200 times) of the core-sheath structure spun yarn in one embodiment of the present invention, in which the blend ratio of wool is 15% by mass when the multi-layered structure spun yarn is 100% by mass. be.
FIG. 5 is a side view photograph (magnification: 200) of the core-sheath structure spun yarn in another embodiment of the present invention. be.
It can be generally said from FIGS. 2 to 5 that the wound fibers in the surface layer firmly wrap the core component fibers and the inner layer fibers of the sheath component, which contributes to the improvement of the friction strength, weft elongation and anti-pilling properties of the fabric. It can be said that
