Abstract
Description
本発明は、弾力性のある導電性ヤーン、その使用法、製造方法に関する。 The present invention relates to an elastic conductive yarn, a method for using the same, and a method for producing the same.
導電性ヤーンを製造する方法はいくつか知られている。例えば、金属線、ワイヤー・メッシュまたは金属糸を織物に直接織り込んで帯電を放出している。これらの織物は多くの場合、織機で製造するが困難であり、金属線が露出しているため、見た目が織物とあまり似ていない、および／または、手触りが金属的な感じがする。 Several methods are known for producing conductive yarns. For example, a metal wire, a wire mesh, or a metal thread is directly woven into the fabric to release the charge. These fabrics are often difficult to manufacture on a loom and the metal lines are exposed so that they look less like the fabric and / or feel like a metal.
他にも、いわゆる短繊維ヤーンを製造する方法が知られている。必然的に、これらの製造方法は、短金属繊維および微細金属繊維と共に短織物繊維を紡いでヤーンにすることに係わっている。金属含有量に応じて、これらのヤーンは程度の差はあるが織物または金属の特性を有する。導電率が高い短繊維ヤーンは金属性の外観と表面の感触を示す。 In addition, a method for producing a so-called short fiber yarn is known. Inevitably, these manufacturing methods involve spinning short woven fibers together with short metal fibers and fine metal fibers into yarns. Depending on the metal content, these yarns have varying degrees of woven or metallic properties. Short fiber yarns with high conductivity exhibit a metallic appearance and surface feel.
中心に支持された金属線が織物を用いて一重または二重に巻かれる方法が知られている。実質的にこれらのヤーンにおいて引張強度を決めるのが線であるため、直径が０．１ｍｍ以上の比較的太い線が通常は使用される。このようなヤーンは相対的に強固であり、そのために織物用途の使用には適さない。 A method is known in which a centrally supported metal wire is wound in a single or double manner using a woven fabric. Since it is the wire that substantially determines the tensile strength in these yarns, a relatively thick wire with a diameter of 0.1 mm or more is usually used. Such yarns are relatively strong and are therefore not suitable for use in textile applications.
ＥＰ ２５０ ２６０では、平行に供給された線と糸を巻きつけることによって、巻き付けられたヤーンの中心に細い線を用いる方法が述べられている。この実施では、中心の糸が引張強度を担うが、その一方で平行な細い線がヤーンの導電率を生み出す。 EP 250 260 describes a method in which a thin line is used at the center of a wound yarn by winding a line and a thread supplied in parallel. In this implementation, the center yarn is responsible for tensile strength, while the parallel thin lines create the conductivity of the yarn.
ＣＨ ６９０ ６８６では、粗紡織物とモノフィラメント金属糸の複合ヤーンの製造について述べている。リング精紡機でヤーン紡績処理中、被覆金属線が粗紡の中心に加えられる。紡績工程に伴う熱処理で、溶融被覆が中心線を紡いだ織物被覆材料に付着させる。これらのヤーンもまた良好な伸展性がみられる。 CH 690 686 describes the production of a composite yarn of roving fabric and monofilament metal yarn. During yarn spinning on a ring spinning machine, a coated metal wire is added to the center of the roving. In the heat treatment associated with the spinning process, the melt coating adheres to the textile coating material spun the centerline. These yarns also show good extensibility.
導電性糸は可塑的に破損するか、または変形するかのいずれかであるため、上記の各ヤーンは導電率の損失無しに弾力的に相当伸びることができない。 Since the conductive yarn is either plastically broken or deformed, each of the above yarns cannot elastically stretch considerably without loss of conductivity.
米国特許番号第４７７６１６０号、第５８８１５４７号、第５９２７０６０号の各明細書で、導電性ヤーンが中心に配列された糸に巻き付けられているヤーンについて記述している。原理上、この配列によって、ヤーンまたは導電性被覆が裂けることなく、ヤーンのユニット全体の特定の伸長を容易にする。 U.S. Pat. Nos. 4,776,160, 5,881,547, and 5,927,060 describe yarns that are wound around a thread having a conductive yarn arranged in the center. In principle, this arrangement facilitates specific stretching of the entire unit of yarn without tearing the yarn or conductive coating.
米国特許番号第５８８１５４７号では、フェンシング・ウェア用に使用するための高張力導電性ヤーンの生産を説明している。これらのヤーンは非導電性芯糸とステンレススチール線を用いた二重の交差被覆とからなる。使用されるステンレススチール線の直径が大きいため、０．６ｍｍから１．２ｍｍの範囲では、ステンレススチール線は非常に硬く、ほとんど伸張性がなく、決して弾力性はない。 U.S. Pat. No. 5,881,547 describes the production of high tensile conductive yarns for use in fencing wear. These yarns consist of a non-conductive core yarn and a double cross-coating using stainless steel wire. Due to the large diameter of the stainless steel wire used, in the range of 0.6 mm to 1.2 mm, the stainless steel wire is very hard, hardly stretchable and never elastic.
米国特許番号第４７７６１６０号および第５９２７０６０号は共に、良好な繊維特性をもつ導電性ヤーンを製造するための弾力性、伸張性のある芯糸の使用法について述べている。米国特許番号第４７７６１６０号では、芯糸用の材料として、ナイロン、ポリエステル、レーヨン、アクリル、ＰＥＥＫ、ＰＢＳ、ＰＢＩ、ポリオレフィン（ＰＥ，ＰＰ）および液晶高分子、ポリカーボネート、ポリビニル・アルコール、アラミド繊維などの熱可塑性物質について述べている。これらのどの材料もゴム弾性特性を有していない。 US Pat. Nos. 4,776,160 and 5,927,060 both describe the use of elastic, extensible core yarns to produce conductive yarns with good fiber properties. In US Pat. No. 4,776,160, materials for core yarn include nylon, polyester, rayon, acrylic, PEEK, PBS, PBI, polyolefin (PE, PP) and liquid crystal polymer, polycarbonate, polyvinyl alcohol, aramid fiber, etc. Describes thermoplastics. None of these materials have rubber elastic properties.
好ましくは、米国特許第５９２７０６０号で述べられているマルチフィラメント合成ヤーンが、導電性に変化を与えることなく約５％まで伸長に耐えることができる。ここに採用される繊維芯糸は全くゴム弾性特性をもたない。さらに、１ｍ当たり２００から６００巻きに過ぎない弱い被覆によって、被覆線が破損する前に指定条件の下で僅かに伸長できるだけである。 Preferably, the multifilament synthetic yarn described in U.S. Pat. No. 5,927,060 can withstand elongation to about 5% without altering conductivity. The fiber core yarn employed here has no rubber elasticity. Furthermore, a weak coating of only 200 to 600 turns per meter can only stretch slightly under specified conditions before the coated wire breaks.
また、最後に記述したヤーンはゴム弾性特性を全くもたない。このヤーンが導電性を失うことなく３％〜５％の範囲で少しの伸長に耐えられるとしても、相当な永久伸びはそのままである。また、最後に記述したヤーンは切れることなく、あるいは最低でも導電性を失うことなく、１０％を超える伸長に耐えることはできない。 Also, the last-mentioned yarn has no rubber elastic properties. Even if this yarn can withstand a slight elongation in the range of 3% to 5% without losing electrical conductivity, the substantial permanent elongation remains the same. Also, the last described yarn cannot withstand over 10% elongation without breaking or at least losing electrical conductivity.
したがって、導電性に加えて、高い弾性と改善された伸長特性を示すヤーンが必要であることに変わりはない。 Thus, in addition to conductivity, there is still a need for yarns that exhibit high elasticity and improved stretch properties.
これは、本発明が適用されるものである。請求項で特徴付けられるような本発明の目的は、導電性があり、導電率を失うことなく少なくとも短時間において相当に伸長でき、そして改善された伸長特性を示すヤーンを提供することにある。 This is to which the present invention is applied. It is an object of the invention as characterized in the claims to provide a yarn that is electrically conductive, can be stretched considerably in at least a short time without losing electrical conductivity, and exhibits improved stretch properties.
本目的は、請求項１によるヤーンによって本発明により解決される。本発明の好都な詳細、様態、実施形態は、独立請求項、説明、実施例からも明らかである。 This object is solved according to the invention by a yarn according to claim 1. Advantageous details, aspects and embodiments of the invention will be apparent from the independent claims, the description and the examples.
本発明によるヤーンは、少なくとも１つの弾性芯糸、芯糸の周りに巻かれた少なくとも１本の導電性糸、および芯糸の周りに巻かれた少なくとも１本の結束糸からなる。導電性ヤーン全体の伸展性は結束糸によって制限を受ける。 The yarn according to the present invention comprises at least one elastic core yarn, at least one conductive yarn wound around the core yarn, and at least one binding yarn wound around the core yarn. The extensibility of the entire conductive yarn is limited by the binding yarn.
このような導電性ヤーンは多数の改善された特性をもつ。このヤーンは、幅広い引張負荷に対して弾性特性を示す。背景技術から知られている導電性ヤーンとは対照的に、引張過負荷により、本発明によるヤーンの導電率が減少することはない。結束糸によるヤーンの伸展性の制限によってこれが達成される。結束糸を介して伸展性を制限することにより、ヤーンが負荷範囲全体で弾性特性を維持することがさらに達成される。 Such conductive yarns have a number of improved properties. This yarn exhibits elastic properties over a wide range of tensile loads. In contrast to the conductive yarns known from the background art, tensile overload does not reduce the conductivity of the yarn according to the invention. This is achieved by limiting the extensibility of the yarn by the tying yarn. By limiting the extensibility via the tying yarn, it is further achieved that the yarn maintains its elastic properties over the entire load range.
本発明の好ましい実施形態によれば、糸の復元力は一定の引張負荷を超えると偏って増加する。復元力におけるこの不均衡が上昇する理由は結束糸に起因する。すなわち、一定の引張負荷を超えると、前記の結束糸は、芯糸の長さ単位当たり巻き数が少なくなるまでらせん形状を広げ、この負荷にもはや耐えることができないが、縦方向における伸展性を介してのみさらなる伸展が可能となる。らせん構造の展開から結束糸の縦方向における結束糸自体の効率的な伸展への移行により、復元力が大幅に強まり、これによってヤーンがさらに伸長するのを防ぐ。復元力におけるこの不均衡の増大は、導電性糸が切れない引張負荷で起こる。故に、ヤーンは導電性なのである。 According to a preferred embodiment of the present invention, the restoring force of the yarn will increase unbalanced beyond a certain tensile load. The reason for this increase in restoring force is due to the tying yarn. That is, when a certain tensile load is exceeded, the above-mentioned binding yarn expands the spiral shape until the number of windings per unit length of the core yarn is reduced, and can no longer withstand this load, but the stretchability in the longitudinal direction is increased. Further extension is possible only through The transition from the development of the helical structure to the efficient extension of the binding yarn itself in the machine direction of the binding yarn significantly increases the restoring force, thereby preventing the yarn from further stretching. This increase in imbalance in restoring force occurs at tensile loads where the conductive yarn does not break. Hence, the yarn is conductive.
結束糸の伸展性の範囲は主に、材料特性や芯糸周囲の結束糸の巻き数による。巻き数が多ければそれだけ大きな伸展性が得られる。これに加えて、材料破損時の高い伸長が伸展性の増大をもたらす。 The range of stretchability of the binding yarn mainly depends on the material properties and the number of windings of the binding yarn around the core yarn. The greater the number of windings, the greater the extensibility. In addition, the high elongation at the time of material failure leads to an increase in extensibility.
破損時の材料の伸長は、材料が破損するまで引張負荷により材料が伸長したことがわかる。それは、応力を加えた材料の強度を判定するのに役立つ。したがって、破損時に伸長性が高い材料は、破損するまでより長く引っ張ることができる。 The elongation of the material at the time of breakage indicates that the material has been stretched by the tensile load until the material is broken. It helps to determine the strength of the stressed material. Thus, a material that is highly extensible when broken can be pulled longer until it breaks.
本発明によると、導電性ヤーンの伸展性は結束糸によって制限を受ける。この特性を満たすには、芯糸、導電性糸、結束糸が、材料および芯糸の周りの導電性糸や結束糸の巻き数に関して、便宜上調整される。さらに、有利には、ヤーン製造技術に熟練した者に知られている要素のいくつが調整される。すなわち、伸展性は芯糸の被覆が起こす力に左右される。また、様々な糸材料が多様な摩擦係数を示し、お互いに対して個々の糸を入れ替えるために必要な力の消費を異なるものにしている。 According to the present invention, the extensibility of the conductive yarn is limited by the binding yarn. In order to satisfy this characteristic, the core yarn, the conductive yarn, and the binding yarn are adjusted for convenience with respect to the material and the number of windings of the conductive yarn and the binding yarn around the core yarn. In addition, advantageously, some of the elements known to those skilled in the yarn manufacturing art are adjusted. That is, the extensibility depends on the force generated by the coating of the core yarn. In addition, various yarn materials exhibit a variety of friction coefficients, making the consumption of force necessary to replace individual yarns relative to each other differ.
ヤーン製造の技術に熟練した者にとって、そのような選定は問題がない。適切な材料および製造項目の選定について、当該技術に熟練した者は通常、特定の芯糸を提示し、それを細い線で覆い、次に規定された特性をヤーンが満たすよう結束糸を指定する。 For those skilled in the art of yarn production, such selection is not a problem. For the selection of the appropriate material and manufacturing items, those skilled in the art usually present a specific core yarn, cover it with a thin line, and then specify the tying yarn so that the yarn meets the specified properties .
生成されたヤーンにおける芯糸の周りの巻き数は、実際に行われた巻き数によってだけでなく、芯糸が事前延伸加工される程度によって影響を受ける。芯糸を事前延伸加工する力が強くなれば、芯糸にかかる負荷を軽減した後、芯糸の長さ単位当たりに存在する巻き数がそれだけ多く劇的に多くなる。 The number of turns around the core yarn in the produced yarn is influenced not only by the number of turns actually performed, but also by the degree to which the core yarn is pre-drawn. If the force for pre-drawing the core yarn is increased, the number of windings existing per length unit of the core yarn is dramatically increased after the load applied to the core yarn is reduced.
本発明の好ましい実施形態によれば、芯糸はゴム弾性材料からなる。「ゴム弾性材料」という用語は、材料の変形およびその後の負荷軽減に伴い、材料の元の状態に再び戻るという意味であることの理解されるであろう。ＤＩＮ ７７２４（１９７２年２月）によれば、エネルギー弾性（スチール弾性）およびエントロピー弾性（ゴム弾性）という２種類の弾性が存在する。 According to a preferred embodiment of the present invention, the core yarn is made of a rubber elastic material. It will be understood that the term “rubber elastic material” means to return to the original state of the material as the material deforms and subsequently reduces the load. According to DIN 7724 (February 1972), there are two types of elasticity: energy elasticity (steel elasticity) and entropy elasticity (rubber elasticity).
本発明の好ましい実施形態によれば、弾性芯糸は少なくとも５０％の破損時、好ましくは少なくとも１００％の破損時、特に好ましくは少なくとも２００％の破損時に伸長を示す。特に非常に好ましくは、芯糸は少なくとも３００％の破損時、特に少なくとも４００％の破損時、特に好ましくは５００％の破損時に伸長を保持する。 According to a preferred embodiment of the invention, the elastic core yarn exhibits elongation upon at least 50% failure, preferably at least 100% failure, particularly preferably at least 200% failure. Very particularly preferably, the core yarn retains elongation when broken at least 300%, especially when broken at least 400%, particularly preferably when broken at 500%.
弾性芯糸はヤーンのユニット全体のゴム弾性特性を担っている。市場には多様なゴム弾性糸が売りに出ており、この中から関連する用途に適した材料を選択できる。これらには天然ゴムや合成ゴム、様々な種類のポリエステルやポリエーテル・エラスタンス、変性ポリエステル、交差結合後可塑性物質などがある。ポリエステル−ポリウレタン・エラストマーおよび／またはポリエーテル−ポリウレタン・エラストマーはゴム弾性芯糸用材料として特に適している。 The elastic core yarn is responsible for the rubber elastic properties of the entire yarn unit. A variety of rubber elastic yarns are on the market, and you can select a material suitable for the relevant application. These include natural and synthetic rubbers, various types of polyesters, polyether elastances, modified polyesters, and post-crosslinked plastics. Polyester-polyurethane elastomers and / or polyether-polyurethane elastomers are particularly suitable as rubber elastic core yarn materials.
伸長に伴い、本発明によるヤーンは、芯糸のゴム弾性特性によって、少なくともほぼ元の長さまで再収縮するはずである。本発明の好ましい実施形態によると、縦方向において少なくとも１５％の弾性伸長に伴い、導電性ヤーンは導電性を失うことなく５％の最大恒久的弾性を示す。特に好ましくは、縦方向に少なくとも３０％の弾性伸長に伴い、導電性ヤーンは導電性を失うことなく５％の最大恒久的弾性を示す。 As stretched, the yarn according to the present invention should re-shrink to at least about its original length due to the rubber elastic properties of the core yarn. According to a preferred embodiment of the present invention, with an elastic elongation of at least 15% in the machine direction, the conductive yarn exhibits a maximum permanent elasticity of 5% without losing conductivity. Particularly preferably, with an elastic elongation of at least 30% in the machine direction, the conductive yarn exhibits a maximum permanent elasticity of 5% without losing conductivity.
関連用途に適する形態で芯糸を使用できる。例を目的として若干の異なる使用法を述べるため、モノフィラメント、マルチフィラメント、セグメント化されたタイプ、テクスチャード加工タイプがある。必要であれば、コアにおいて並列またはより糸の形態で多重糸を使用することもでる。同種の糸または種類が異なる糸を一緒に使用することもできる。 The core yarn can be used in a form suitable for related applications. There are monofilaments, multifilaments, segmented types, and textured types to describe a few different uses for example purposes. If necessary, multiple yarns can be used in the form of parallel or twisted yarns in the core. The same type of yarn or different types of yarn can also be used together.
複合ヤーンの弾性芯は少なくとも１つの導電性被覆を用いて仕上げられる。弾性コアは導電性糸を複数回巻き付けられる。これらの導電性被覆は異なる被覆方向にも応用できる。適切な場合、それらは中間層によってお互いに切り離すこともできる。 The elastic core of the composite yarn is finished with at least one conductive coating. The elastic core is wound around the conductive yarn a plurality of times. These conductive coatings can also be applied in different coating directions. If appropriate, they can also be separated from each other by an intermediate layer.
金属線、ワイヤより糸またはメッシュ、導電性被覆合成繊維、金属部分を有する短繊維糸、導電性ポリエステルの糸および導電性充填合成繊維は、特に導電性糸として適している。導電性糸は単一等級または混成から、単一または複数重なって使用されることもできる。導電性糸として使用するモノフィラメント金属線は直径が０．０１〜０．１ｍｍで、好ましくは０．０２〜０．０６ｍｍで、特に好ましくは０．０３〜０．０５ｍｍである。 Metal wires, wire strands or meshes, conductive coated synthetic fibers, short fiber yarns with metal parts, conductive polyester yarns and conductive filled synthetic fibers are particularly suitable as conductive yarns. Conductive yarns can be used from single grade or hybrid, single or multiple. The monofilament metal wire used as the conductive yarn has a diameter of 0.01 to 0.1 mm, preferably 0.02 to 0.06 mm, and particularly preferably 0.03 to 0.05 mm.
原則として、さらに被覆、陽極化、またはエッチングされる無数の金属および合金が導電性糸として適しているが、銅線、銀メッキ銅線、ステンレス鋼線材が、技術的および経済的要因から特に好ましい。被覆線またはラッカー塗り線タイプの使用により、本発明によるヤーンの耐腐食性および洗浄性が向上する。このようなヤーンは容易に洗浄できるだけでなく、その上、ドライクリーニングにも耐えられる。 In principle, countless metals and alloys that are further coated, anodized or etched are suitable as conductive yarns, but copper wire, silver-plated copper wire, stainless steel wire are particularly preferred due to technical and economic factors. . The use of coated or lacquered wire types improves the corrosion resistance and cleanability of the yarn according to the invention. Such yarns can not only be cleaned easily, but also withstand dry cleaning.
モノフィラメント金属線に加えて、マルチフィラメントステンレス鋼ヤーンが、本発明によるヤーンを製造するのに極めて適している。単一ステンレス鋼フィラメントの厚みは０．００２〜０．０２ｍｍの範囲である。含まれる個々のフィラメント数は１０〜２００の範囲である。 In addition to monofilament metal wires, multifilament stainless steel yarns are very suitable for producing the yarns according to the invention. The thickness of the single stainless steel filament is in the range of 0.002 to 0.02 mm. The number of individual filaments included is in the range of 10-200.
弾性芯の導電性被覆銀メッキ合成ヤーンの使用により、無数の用途に役立つ。耐洗浄の銀メッキ・ナイロン糸は特に、本発明によるヤーンを製造するのに適している。モノフィラメントヤーンとマルチフィラメントヤーンの両方が市場で売られている。モノフィラメント繊維と比べると、より高い表面被覆率が同じヤーン直径で、被覆としてマルチフィラメントヤーンを用いて達成される。 Use of elastic core conductive coated silver plated synthetic yarns serves a myriad of applications. Wash-resistant silver-plated nylon yarns are particularly suitable for producing the yarns according to the invention. Both monofilament yarns and multifilament yarns are sold on the market. Compared to monofilament fibers, higher surface coverage is achieved with the same yarn diameter and using a multifilament yarn as the coating.
導電性被覆に加えて、ヤーンはさらなる被覆を含む。このような被覆は様々な機能の役割を担っている。いくつかを例として挙げると、電気絶縁（外面的、内面的、または多層導電層間）、機械磨耗保護、高速運転機械でのヤーンの作業性の向上、色、光沢、外見、握り、表面の感触、伸び過ぎ防止、引張強度、一方向への被覆後のヤーンの内部ねじれの応力の均等化がある。この結束糸は通常、導電性ではないことを指摘することも必要である。しかしながら、本発明は、わずかにでも導電性を示す結束糸も含む。 In addition to the conductive coating, the yarn includes a further coating. Such a coating plays a role of various functions. Some examples include electrical insulation (external, internal, or multi-layer conductive layers), mechanical wear protection, improved yarn workability on high speed machines, color, gloss, appearance, grip, surface feel There are over-extension prevention, tensile strength, equalization of the internal twisting stress of the yarn after coating in one direction. It should also be pointed out that this tying yarn is usually not conductive. However, the present invention also includes a tying yarn that exhibits a slight electrical conductivity.
無数の用途に対して、内方向に位置する弾性芯を有するヤーン構造、導電性糸を用いた内側被覆、それと反対方向に実行される織物外側被覆が適している。伸長が強い場合、内側に位置する導電性被覆の前に完全に引き伸ばされるように外側被覆は構成されている。このようにして、外側被覆は導電性被覆が損傷を受ける前に外側被覆の伸長を破断する。 For a myriad of applications, a yarn structure with an elastic core located in the inward direction, an inner covering using conductive yarns, and a textile outer covering performed in the opposite direction are suitable. If the extension is strong, the outer coating is configured to be fully stretched before the conductive coating located on the inner side. In this way, the outer coating breaks the extension of the outer coating before the conductive coating is damaged.
本発明によるヤーンのさらに好ましい実施形態には、非導電性被覆としてマルチフィラメントヤーンの使用法がある。芯を被覆するとき、マルチフィラメントヤーンは好ましくは、芯糸上にこのヤーン自身の薄層を形成し、それにより、モノフィラメントと比べて同じ直径で、表面被覆率に相当大きい影響を与える。 A further preferred embodiment of the yarn according to the invention includes the use of a multifilament yarn as a non-conductive coating. When coating the core, the multifilament yarn preferably forms a thin layer of the yarn itself on the core yarn, thereby having a considerably greater effect on the surface coverage at the same diameter as the monofilament.
用途に応じて、すべての種類の糸が今までに述べた被覆に適用することができる。例を目的として可能な材料の代表のいくつかを挙げると、ナイロン、ポリエステル、レーヨン、ポリアミド、亜麻糸、羊毛、絹、綿、ポリプロピレン、様々な実施形態におけるケブラー、すべての種類の混成ヤーン、銀メッキナイロンのような金属ヤーンがある。 Depending on the application, all types of yarns can be applied to the coatings described so far. Some examples of possible materials for example purposes include nylon, polyester, rayon, polyamide, flax yarn, wool, silk, cotton, polypropylene, Kevlar in various embodiments, all types of hybrid yarn, silver There are metal yarns such as plated nylon.
本発明によるヤーンの製造は様々な方法で実行できる。好ましい方法は従来のヤーン巻線である。ここでは、延伸装置で中心弾性糸が延伸される。延伸された弾性芯糸は回転中空軸の中を通過する。中空軸上に導電性糸または結束糸が巻き付いたボビンが着座している。この糸は、導電性糸または結束糸がらせん形状で芯糸の周りに巻き取られるよう、均一に取り出される弾性芯糸によって一緒に運ばれる。延伸芯糸は巻き付き後に再び緩むと、個々の巻きは巻き付け中よりも実質的に最終の状態である。 The production of the yarn according to the invention can be carried out in various ways. A preferred method is conventional yarn winding. Here, the central elastic yarn is drawn by a drawing device. The stretched elastic core yarn passes through the rotating hollow shaft. A bobbin around which a conductive yarn or a binding yarn is wound is seated on a hollow shaft. The yarn is carried together by an elastic core yarn that is uniformly removed so that the conductive yarn or the binding yarn is wound around the core yarn in a spiral shape. When the drawn core yarn is loosened again after winding, the individual windings are in a substantially final state than during winding.
非弾性ヤーンと比べると、別の同一の生産条件下で、巻き付け後の記述されたヤーンの緩和に起因する相当に引き締まった回転となるハイ・ドラフトでゴム弾性ヤーンが生産されることができる。前述の方法で、非弾性ヤーンよりもよりきつく弾性ヤーンを巻き付けることができる。 Compared to non-elastic yarns, rubber elastic yarns can be produced at high drafts that result in a fairly tight rotation due to relaxation of the described yarn after winding under different identical production conditions. In the manner described above, elastic yarns that are tighter than non-elastic yarns can be wound.
基本原理として、芯糸にさらに糸を巻き付けることで内部引張応力が生じ、ヤーンが弛緩状態となる。すなわち、ボビンから巻き戻し時、それ自体で巻き付く。芯糸の周りに２本の糸を巻き付けると、上記の内部引張応力が解消する可能性がある。これはヤーンの「平衡」と呼ばれている。すなわち、第１の糸とは反対方向に第２の糸を芯糸の周りに巻き付けると、反対方向にねじれの力が生じる。ここで、単純な実験を用いると、ねじれの力の大きさがほぼ均等となり、その結果としてほぼゼロのねじれの力がもたらすよう材料および巻き数を調整できる。この結果、弛緩状態のヤーンは、仮にあってもそれ自体は全くゆがむことがなくなる。 As a basic principle, when the yarn is further wound around the core yarn, an internal tensile stress is generated, and the yarn is in a relaxed state. That is, when rewinding from the bobbin, it winds by itself. When two yarns are wound around the core yarn, the internal tensile stress may be eliminated. This is called the “balance” of yarn. That is, when the second yarn is wound around the core yarn in the direction opposite to the first yarn, a twisting force is generated in the opposite direction. Here, using simple experiments, the material and number of turns can be adjusted so that the magnitude of the torsional force is approximately equal, resulting in a substantially zero torsional force. As a result, the relaxed yarn is not distorted at all even if it is temporarily.
したがって、本発明の好ましい実施例によれば、導電性糸および結束糸は弾性芯糸の周りに反対方向で巻き付けられる。したがって、例えば、導電性糸がＳ方向に弾性芯糸周囲に巻き付けられていたら、結束糸はＺ方向に弾性芯糸の周りに巻き付けられる。したがって、この方法は交差被覆である。 Thus, according to a preferred embodiment of the present invention, the conductive yarn and the binding yarn are wound around the elastic core yarn in opposite directions. Therefore, for example, if the conductive yarn is wound around the elastic core yarn in the S direction, the binding yarn is wound around the elastic core yarn in the Z direction. This method is therefore a cross-coating.

１８８０ｄｔｅｘの強度をもつライクラ１６３Ｃ（Ｌｙｃｒａ１６３Ｃ）（製造業者：ＤｕＰｏｎｔ Ｄｅ Ｎｅｍｏｕｒｓ Ｉｎｔｅｒｎａｔｉｏｎａｌ Ｓ．Ａ Ｆｉｂｒｅｓ Ｄｅｐａｒｔｍｅｎｔ、Ｄｕ Ｐｏｎｔ Ｓｔｒａｅｓ １，Ｄ−６１３５２、Ｂａｄ Ｈｏｍｂｕｒｇ；製品名：ライクラ弾性ヤーン（ＬＹＣＲＡ ｅｌａｓｔａｎｅ ｙａｒｎ；ｄｔｅｘ／型：１８８０ ｄｔｅｘ Ｔ．１３６Ｃ）は、糸巻線機で事前延伸される。糸の破損時の伸長は５００％で、引裂強度が１３００ｃＮである。１００％の伸長後、２．４％の永続伸長を除いて糸は弛緩する。 Lycra 163C with strength of 1880 dtex (Lycra 163C) (Manufacturer: DuPont De Nemours International, Du Pont Stras 1, D-6135, Bad Homburg; Product name: : 1880 dtex T.136C) is pre-drawn with a yarn winding machine, the elongation at break of the yarn is 500% and the tear strength is 1300 cN.After 100% elongation, 2.4% permanent elongation The thread relaxes except.
事前延伸されたライクラ（Ｌｙｃｒａ）糸を中空軸に通す。この中空軸は、太さ０.０４ｍｍの硬質銀メッキ銅線（製造業者：Ｅｌｅｋｔｒｏ−Ｆｅｉｎｄｒａｈｔ ＡＧ ｉｎ ＣＨ−８１８２ Ｅｓｃｈｏｌｚｍａｔｔ；製品名：被覆型ＴＷ−Ｄであるテキスタイル・ワイヤ銀／銅）がライクラ（Ｌｙｃｒａ）糸によってオーバエンドで円錐ヤーン軸から取り出され、その円錐ヤーン軸を運ぶ。ラッカー塗装を施した線の直径は０．０４８ｍｍである。線は２１．３％の破損時に伸長を示す。 A pre-drawn Lycra yarn is passed through the hollow shaft. This hollow shaft is made of lycra (0.04 mm thick hard silver-plated copper wire (manufacturer: Elektro-Feindragt AG in CH-8182 Escholzmatt; product name: textile wire silver / copper of coated TW-D)). Lycra) is removed from the conical yarn shaft at the overend and carries the conical yarn shaft. The diameter of the lacquered wire is 0.048 mm. The line shows elongation at 21.3% failure.
単一巻き付き線であるライクラ（Ｌｙｃｒａ）は第２の中空軸を通過する。この中空軸は７８ｄｔｅｘを有するＰＡ６６の市販のマルチフィラメント・ポリアミド・ヤーンおよび３４の個別フィラメント（製造業者：Ｒａｄｉｃｉｆｉｌ Ｓ．ｐ．Ａ．／Ｓｙｎｆｉｌ ＧｍｂＨ，ＩＴ−２４１２６ Ｂｅｒｇａｍｏ；名称：ＲＮ０１２３５＿７８／３４／１Ｓ；破損の伸長；２８％）を搬送する。ＰＡ６６ヤーンを線に対抗する芯の周りに巻き付ける。内部ねじれの応力ができる限り生じない均衡化ヤーンが生成されるよう機械パラメータを選択する。 A single winding line, Lycra, passes through the second hollow shaft. This hollow shaft is a commercial multifilament polyamide yarn of PA66 with 78 dtex and 34 individual filaments (Manufacturer: Radicifil SpA / Synfil GmbH, IT-24126 Bergamo; Name: RN01235_78 / 34 / 1S; Deliver breakage elongation; 28%). Wrap PA66 yarn around the core against the wire. Machine parameters are selected to produce a balanced yarn that produces as little internal torsional stress as possible.
外側ＰＡ６６ヤーンをヤーン１ｍ当たり３２００回芯の周りに巻き付ける。すなわち、内側線はヤーン１ｍ当たり３６００回芯の周りに巻き付けられる。内側敷設線はほぼ完全に外側敷設線ＰＡ６６ヤーンによって覆われるため、このヤーンは織物の外観と表面感触をもつ。このヤーンは導電性が優れている。約２５０％まで伸長すると、このヤーンの復元力はＰＡ６６ヤーンの完全な伸長により不相応に強くなる。約３００％伸長されたときのみ、ヤーンは線破損のために導電性を失う。 Wind the outer PA66 yarn around 3200 cores per meter of yarn. That is, the inner line is wound around 3600 cores per meter of yarn. Since the inner laying line is almost completely covered by the outer laying line PA66 yarn, this yarn has the appearance and surface feel of a fabric. This yarn is highly conductive. When stretched to about 250%, the restoring force of this yarn becomes disproportionately strong due to full stretching of the PA66 yarn. Only when stretched about 300% does the yarn lose conductivity due to wire breakage.
実施例１における弾性の導電性複合ヤーンを市販の動力織機に横糸として採用している。縦糸巻きは、８本の糸を１束にした太さ０．３ｍｍの単一縒り合わせ綿糸で構成される。織り合わせると、横糸方向に優れた導電性をもつが、縦糸の方向には電流を通さない頑丈な繊維が生成される。これらの電気特性は、横糸方向に１２０％以上伸長した後でも維持される。縦糸方向に間隙を介して直流電圧源の極が接続されている場合、横糸方向に１ｍの間隔でこの電圧を使って発光ダイオードのような電気受信装置を作動できる。繊維を横糸方向に限界まで引き伸ばしても発光ダイオードの電源に影響を与えることはない。 The elastic conductive composite yarn in Example 1 is adopted as a weft in a commercially available power loom. The warp winding is composed of a single twisted cotton yarn having a thickness of 0.3 mm in which eight yarns are bundled. When weaved together, a strong fiber is produced that has excellent conductivity in the weft direction but does not conduct current in the warp direction. These electrical characteristics are maintained even after extending 120% or more in the weft direction. If the poles of the DC voltage source are connected via a gap in the warp direction, an electrical receiver such as a light emitting diode can be operated using this voltage at intervals of 1 m in the weft direction. Even if the fiber is stretched to the limit in the weft direction, the power source of the light emitting diode is not affected.
実施例１における弾性の導電性複合ヤーンを市販の動力織機で横糸として採用している。縦糸巻きは導電性ではあるがゴム弾性複合であるヤーンからなる。縦糸を製造するため、１００ｄｔｅｘで３６の個別フィラメントを有する市販のポリエステルヤーンは、太さ０.０４１ｍｍの内側被覆、硬質銀メッキ銅線、７８ｄｔｅｘで３４の個別フィラメントを有する市販のポリアミドヤーンが具備されている。 The elastic conductive composite yarn in Example 1 is adopted as a weft in a commercially available power loom. The warp spool is made of yarn which is conductive but rubber elastic composite. To produce warp yarn, a commercial polyester yarn with 36 individual filaments at 100 dtex is equipped with a 0.041 mm thick inner coating, hard silver plated copper wire, a commercial polyamide yarn with 34 individual filaments at 78 dtex. ing.
織り合わされると、横糸方向に優れた導電性をもち、横糸方向の導電性とは独立した縦糸方向に導電性をもつ頑丈な繊維が生成される。横糸方向に１２０％以上伸長された後であっても、これらの電気特性が維持される。この繊維は生産が経済的で、電子活性化を有し、空間的分解信号捕捉用、またはモニターなどの空間的分出力装置用のマトリックスとして使用できる。 When woven together, a strong fiber is produced that has excellent conductivity in the weft direction and is conductive in the warp direction independent of the conductivity in the weft direction. Even after 120% or more elongation in the weft direction, these electrical characteristics are maintained. This fiber is economical to produce, has electronic activation, and can be used as a matrix for capturing spatially resolved signals or for spatial output devices such as monitors.
１８８０ｄｔｅｘのライクラ１６３０Ｃ（Ｌｙｃｒａ １６３Ｃ）（ＤｕＰｏｎｔ Ｎｅｍｏｕｒｓ ＧｍｂＨ， Ｄｕ Ｐｏｎｔ Ｓｔｒａｅｓ １， Ｄ−６１３５２， Ｂａｄ Ｈｏｍｂｕｒｇ）の弾性糸は、ヤーン巻線機で事前延伸される。この事前延伸されたライクラ（Ｌｙｃｒａ）糸は中空軸を通される。この中空軸は、３０デニールで、１８の個々のフィラメント（Ｘ−ｓｔａｔｉｃ，Ｌｉｆｅ ＳＲＬ，１−２５０１５ Ｄｅｓｅｎｚａｎｏ，イタリア）を有する銀メッキ銅線がライクラ（Ｌｙｃｒａ）糸によってオーバエンドで円錐ヤーン軸から取り出され、その円錐ヤーン軸を運ぶ。銀メッキした繊維で単一巻き付けしたライクラ（Ｌｙｃｒａ）は第２の中空軸を通過する。この中空軸は３３ｄｔｅｘであるＰＡ６６の市販マルチフィラメント・ポリアミドヤーンおよび１０の個別フィラメントを搬送する。ＰＡ６６ヤーンを銀メッキ繊維に対抗する芯の周りに巻き付ける。内部ねじれの応力ができる限り生じない均衡化ヤーンが生成されるよう機械パラメータを選択する。外側ＰＡ６６ヤーンをヤーン１ｍ当たり３２００回芯の周りに巻き付ける。すなわち、内側線はヤーン１ｍ当たり３６００回芯の周りに巻き付ける。内側敷設銀メッキ糸はほぼ完全には外側敷設線ＰＡ６６ヤーンによって覆われていない。このヤーンは導電性が優れている。約２５０％まで伸長すると、このヤーンの復元力はＰＡ６６ヤーンの完全な伸展により不相応に強くなる。約３２０％伸長されたときのみ、このヤーンがライクラ（Ｌｙｃｒａ）芯破損を被覆する。 The elastic yarn of 1880 dtex lycra 1630C (Lycra 163C) (DuPont Nemours GmbH, Du Pont Straes 1, D-61352, Bad Homburg) is pre-stretched with a yarn winding machine. This pre-drawn Lycra yarn is passed through a hollow shaft. This hollow shaft is 30 denier and a silver-plated copper wire with 18 individual filaments (X-static, Life SRL, 1-225015 Desenzano, Italy) is taken from the conical yarn shaft at the overend by Lycra yarn. It carries its conical yarn axis. A lycra wound with a silver-plated fiber passes through a second hollow shaft. This hollow shaft carries a commercial multifilament polyamide yarn of PA66 which is 33 dtex and 10 individual filaments. Wrap PA66 yarn around the core against silver-plated fiber. Machine parameters are selected to produce a balanced yarn that produces as little internal torsional stress as possible. Wind the outer PA66 yarn around 3200 cores per meter of yarn. That is, the inner line is wrapped around 3600 cores per meter of yarn. The inner laying silver-plated yarn is almost completely not covered by the outer laying line PA66 yarn. This yarn is highly conductive. When stretched to about 250%, the restoring force of this yarn becomes disproportionately strong due to the complete extension of the PA66 yarn. This yarn only covers Lycra core breakage when stretched by about 320%.
実施例４における弾性の導電性複合ヤーンを市販動力織機の横糸として使用する。縦糸巻きは導電性ではあるが、ゴム弾性複合ヤーンではないヤーンからなる。縦糸を製造するには、１００ｄｔｅｘで３６の個別フィラメントを有する市販のポリエステルヤーンは、３０デニールで１８の個別フィラメントを有する銀メッキ・ポリアミド糸（Ｘ−ｓｔａｔｉｃ，Ｌｉｆｅ ＳＲＬ，１−２５０１５ Ｄｅｓｅｎｚａｎｏ，Ｉｔａｌｙ）および３３ｄｔｅｘで１０の個別フィラメントを有する市販ポリアミドヤーン（ＰＡ６６）が備えられる。 The elastic conductive composite yarn in Example 4 is used as the weft of a commercial power loom. The warp is composed of a yarn that is electrically conductive but not a rubber elastic composite yarn. To produce warp yarns, commercially available polyester yarns with 36 individual filaments at 100 dtex are silver-plated polyamide yarns with 18 individual filaments at 30 denier (X-static, Life SRL, 1-225015 Desenzano, Italy) And a commercial polyamide yarn (PA66) with 10 individual filaments at 33 dtex.
織り合わされると、優れた導電性を持つ頑丈な繊維が生成される。縦糸と横糸両方における銀メッキ被覆の不完全な絶縁のために、繊維におけるすべての導電性ヤーンはお互いに電気的接触をもつ。この方向依存の導電性は、横糸方向に１００％以上伸長した後でも保持される。このような繊維は、特に１〜２０００ＭＨｚの範囲において電磁放射線に対して優れた遮蔽特性をもつ。 When interwoven, a sturdy fiber with excellent electrical conductivity is produced. Due to the incomplete insulation of the silver plating coating on both the warp and weft, all the conductive yarns in the fiber have electrical contact with each other. This direction-dependent conductivity is maintained even after extending 100% or more in the weft direction. Such fibers have excellent shielding properties against electromagnetic radiation, particularly in the range of 1 to 2000 MHz.
実施例１における弾性導電性複合糸は、市販リボン織り機で縦糸として使用されている。縦糸巻きは交互に各々連続する８本の同一糸で構成される。一つおきの配列は、実施例１で記述した８本のヤーンの束と導電性部をもたないヤーンとの間で起こる。導電性部をもたない糸は、ワイヤーの代わりに、７８ｄｔｅｘで３４の個別フィラメントを有するPA６６のマルチフィラメントが使用されているということを除いて、実施例１で記述したヤーンに完全に大部分が対応している。市販マルチフィラメント・ポリアミドヤーンが横糸して使用される。 The elastic conductive composite yarn in Example 1 is used as warp in a commercially available ribbon weaving machine. The warp winding is composed of eight identical yarns that are alternately continuous. Every other arrangement takes place between the bundle of eight yarns described in Example 1 and the yarns without conductive parts. The yarn without conductive part is completely entirely in the yarn described in Example 1 except that instead of wire, PA66 multifilaments with 34 individual filaments at 78 dtex are used. Corresponds. Commercially available multifilament polyamide yarns are used as weft yarns.
このようにして製造された弾性リボンは、相互に電気的に絶縁されている共存導体リボンを保持している。湿った環境でさえも導体リボン間の短絡を回避するためには、プラスチック被覆線を使用してヤーンを製造することが都合が良い。この実施例で記述する平たい弾性ケーブルは、衣類における電気・電子構成部品を接続するのに際立って適している。リボンは、導電性を失うことなく、縦糸方向に引き伸ばすことができる。リボンは、衣類が擦り切れたときに起こるしわや折り目に対して反応しない。 The elastic ribbon manufactured in this way holds coexisting conductor ribbons that are electrically insulated from each other. In order to avoid shorts between the conductor ribbons even in a moist environment, it is advantageous to manufacture the yarn using plastic-coated wires. The flat elastic cable described in this example is outstandingly suitable for connecting electrical and electronic components in clothing. The ribbon can be stretched in the warp direction without losing electrical conductivity. Ribbons do not react to wrinkles or creases that occur when clothing is frayed.
実施例２における弾性横糸方向導電性繊維は、幅１．１ｃｍおよび長さ５０ｃｍの市販フラット・ケーブル・コネクタによって横糸方向に電気的に接触される。直流電圧が印加されると、電流が流れる。接続点の間の中間での、電流の流れによって生じる温度上昇はＮＴＣ抵抗によって求められる。５Ｗ（３．６Ｖ時に１．４Ａ）の熱出力において、温度は３０℃に達する。１３Ｗ（６．５Ｖ時に２Ａ）の熱出力において、温度は６４．５℃に達する。 The elastic weft direction conductive fibers in Example 2 are electrically contacted in the weft direction by a commercial flat cable connector having a width of 1.1 cm and a length of 50 cm. When a DC voltage is applied, a current flows. The temperature rise caused by the current flow in the middle between the connection points is determined by the NTC resistance. At a heat output of 5 W (1.4 A at 3.6 V), the temperature reaches 30 ° C. At a heat output of 13 W (2 A at 6.5 V), the temperature reaches 64.5 ° C.
繊維の伸展性と織物表面感触は、身体と直接触れる弾性の導電加熱可能織物の製造に極めて適したものになっている。用途例としては、靴下、ジョイント・ウォーマ、バック・ウォーマ、手袋、弾性包帯などがある。
Fiber extensibility and fabric surface feel are well suited for the production of elastic conductive heatable fabrics that are in direct contact with the body. Examples of applications include socks, joint warmers, back warmers, gloves, and elastic bandages.
