Abstract

In the production of a yarn (13) with electrical conductivity, the textile component is a slubbing of textile fibres (12) to clad a continuous electrically conductive and coated monofilament metal thread (11) from the side and around it. They are fed directly into the centre of a spinning station (1) of a ring spinner. They are spun together into a cladded yarn where the metal thread (11) is under no drawing tension, while the slubbing (12) is drawn a number of times before entering the spinning station (1). The cladded yarn is taken off for further processing. Also claimed is a cladded yarn, where the electrically conductive metal thread (11) is a coated copper filament.

Description

Die Erfindung betrifft ein Verfahren zur Herstellung eines elektrisch leitenden Verbundgarnes nach dem Oberbegriff des unabhängigen Patenanspruches. Die Erfindung betrifft dazu auch das nach dem Verfahren hergestellte elektrisch leitende Garn selbst und dessen Verwendung.The invention relates to a method for producing a electrically conductive composite yarn according to the preamble of independent patent claim. The invention also relates to this the electrically conductive yarn produced by the process itself and its use.

Es wurden schon einige Versuche zur Herstellung von elektrisch leitenden textilen Stoffen gemacht. Einerseits sind Gewebe mit Einlagen von Metallfäden bekannt. Damit das Verweben von Metallfäden weniger Problem am Webstuhl verursacht, wurden versucht, die Metallfäden bereits in ein Mischgarn oder in eine Verbundgarn zu verarbeiten.There have been several attempts to manufacture electrical conductive textile fabrics. On the one hand, fabrics are included Deposits of metal threads are known. So that the interweaving of Metal threads were less of a problem on the loom tried to put the metal threads in a blended yarn or in a Process composite yarn.

Ein Herstellungsverfahren eines solches Verbundgarn ist beispielsweise aus W093/24689 bekannt. Es handelt sich um ein Verbundgarn aus Textilfaser gleicher oder unterschiedlicher Art, welche mit einem Metalldraht aus geglühtem, versilberten oder vergoldeten Kupfer oder aus geglühtem, rostfreiem Stahl, mit einem Durchmesser von zwischen 0.008 und 0.05 mm gezwirnt ist. Nach dem Zwirnen des Verbundgarnes befindet sich der Metalldraht im wesentlichen in axialer Längsrichtung zwischen den gegenseitigen Berührungszonen der einzelnen Textilfäden. One method of manufacturing such a composite yarn is known for example from W093 / 24689. It's about a Composite yarn made of textile fibers of the same or different Kind, which with a metal wire from annealed, silver-plated or gold-plated copper or from annealed, stainless steel, with a diameter between 0.008 and 0.05 mm is. After twisting the composite yarn is the Metal wire essentially in the axial longitudinal direction between the mutual contact zones of the individual textile threads.

Der Metalldraht bleibt dabei annähernd gestreckt innerhalb dem Verbundgarn. Dafür ist die Bindung zwischen den Teilgarnen und dem Draht nicht immer genügend und es besteht die Gefahr, dass das Verbundgarn bei der Weiterverarbeitung wieder aufgetrennt wird.The metal wire remains approximately stretched within the Composite yarn. This is the bond between the partial yarns and the wire is not always sufficient and there is a risk that the composite yarn is separated again during further processing becomes.

Ein weiteres vergleichbares Verfahren ist in EP-A-0 644 283 beschrieben. Dabei werden metallische Drähte und textile Fäden zusammengeführt und miteinander verzwirnt. Ein Vorteil dieses Verbundgarnes besteht darin, dass die Bindung zwischen textilen Fäden und den Metalldrähten sehr gut ist. Dies wird aber mit dem Nachteil erkauft, dass die Metalldrähte bereits mechanisch erheblich vorbelastet sind und das Verbundgarn relativ steif ist und daher bruchanfällig sind..Another comparable method is in EP-A-0 644 283 described. This involves metallic wires and textile threads merged and twisted together. An advantage of this Composite yarn is that the bond between textile Threads and the metal wires is very good. But this is with bought the disadvantage that the metal wires are already mechanical are significantly preloaded and the composite yarn is relatively stiff is and are therefore prone to breakage ..

Aus EP-A-0 250 260 ist die Verwendung eines metallhaltigen Verbundgarnes für Abschirmungen bekannt, wobei das Verbundgarn aus einem Kern und einer Umhüllung besteht. Es umfasst metallische und nicht metallische Fasern, wobei der Kern im wesentlichen ein kontinuierliches metallisches Filament, verstärkt durch nicht metallisches Filament oder Garn, enthält und die Umhüllung ein nicht metallisches Filament oder Garne enthält, welches um den Kern gewunden ist und mindestens 70% der Mantelfläche des Verbundgarnes ausmacht, wobei die nicht metallischen Fasern aus chemischen oder synthetischen Fasern oder Naturfasern gebildet sind. Auch hierbei ist das Verbundgarn durch Zwirnen entstanden und weist dessen Vorteile und Nachteile auf.EP-A-0 250 260 describes the use of a metal-containing one Composite yarns for shields are known, the composite yarn consists of a core and a cladding. It includes metallic and non-metallic fibers, the core in essentially a continuous metallic filament, reinforced with non-metallic filament or yarn and the wrapping is a non-metallic filament or yarn contains which is wound around the core and at least 70% makes up the outer surface of the composite yarn, which is not metallic fibers made of chemical or synthetic fibers or natural fibers are formed. This is also here Composite yarn was created by twisting and shows its advantages and disadvantages.

Bei US 3 987 613 wird ein Verfahren zur Herstellung eines Verbundgarnes, eigentlich besser bezeichnet als Mischgarn, angegeben, welches im Gegensatz zu den vorhergehenden, nicht durch Zwirnen entsteht. Es werden kurze Kupferfasern mit einem Durchmesser von 0.025 mm und einer Länge von etwa 40 mm vor der Garnherstellung mit textilen Fasern gemischt und anschliessend miteinander zu einem Garn versponnen. Das gesponnene Mischgarn enthält zwischen 0.25 und 15 Gewichtsprozent metallische Fasern. Damit ein derartiges gesponnenes Mischgarn elektrisch leitend wird müsste es einen bedeutend höheren Anteil an Metallfasern enthalten, damit diese im Garn selbst auch genügend Kontakt untereinander aufweisen. Dies Metallfasern sind naturgemäss über den ganzen Garnquerschnitt verteilt. Weil sie auch an der Garnoberfläche vorhanden sind, verursachen sie beim spinnen selbst und bei jeder Weiterverarbeitung erhebliche Abnützung an den jeweiligen Verarbeitungseinrichtungen und Maschinen und die Weiterverarbeitung ist problematisch.No. 3,987,613 describes a method for producing a Composite yarns, actually better known as blended yarn, specified, which in contrast to the previous, not is created by twisting. There are short copper fibers with a Diameter of 0.025 mm and a length of about 40 mm in front of the Yarn production mixed with textile fibers and then spun together into a yarn. The spun blended yarn contains between 0.25 and 15 weight percent metallic Fibers. So that such a spun mixed yarn electrically it should become a significantly higher proportion Contain metal fibers so that they are in the yarn itself have enough contact with each other. This is metal fibers are naturally distributed over the entire yarn cross-section. Because they are also present on the yarn surface, they cause considerable with spinning itself and with every further processing Wear at the respective processing facilities and Machines and further processing are problematic.

Aufgabe der Erfindung ist es, ein Verbundgarn mit einem elektrisch leitenden und einem textilen Anteil, insbesondere Baumwolle, zu schaffen, welches die erwähnten Nachteile nicht mehr aufweist, eine gute Bindung von elektrisch leitendem Material und textilen Fasern gewährleistet und gut zu textilen Flächengebilden, wie Geweben und Gestricken weiter verarbeitbar ist. Besonders wichtig ist dabei, dass der elektrisch leitende Anteil möglichst bei der Verarbeitung und Weiterbearbeitung wenig Schäden und Abnützung an den Maschinen verursacht und möglichst wenig mechanisch vorbeansprucht wird.The object of the invention is a composite yarn with a electrically conductive and a textile portion, in particular To create cotton, which does not have the disadvantages mentioned has more, a good bond of electrically conductive Material and textile fibers guaranteed and good to textile Flat structures such as fabrics and knitted fabrics can be processed further is. It is particularly important that the electrically conductive Share if possible in processing and further processing little damage and wear and tear to the machines is mechanically pre-stressed as little as possible.

Eine weitere Aufgabe der Erfindung ist einerseits das Garn selbst und andererseits die spezielle Verwendung des Garnes für textile Flächengebilde zur Abschirmung, Ableitung und Verhinderung von elektrischen Feldern und deren Einflüssen.Another object of the invention is yarn on the one hand itself and on the other hand the special use of the yarn for textile fabrics for shielding, derivation and Prevention of electrical fields and their influences.

Diese Aufgabe wird durch die in den Patentanspruchen angegebene Erfindung gelöst.This object is achieved by the specified in the claims Invention solved.

Die Erfindung wird nachstehend im Zusammenhang mit den Zeichnungen beschrieben. Es zeigen:

  • Figur 1 eine schematische Darstellung des erfindungsgemässen Verfahrens
    und
  • Figur 2 einen Querschnitt durch ein nach diesem Verfahren erzeugtes Verbundgarn.
    • The invention is described below in connection with the drawings. Show it:
  • Figure 1 is a schematic representation of the inventive method
    and
  • Figure 2 shows a cross section through a composite yarn produced by this method.

    • Spezielle Probleme stellen sich seit jeher beim Herstellen eine Verbundes von Textilien mit Metallen. Ein Metalldraht oder Metallfaden weist immer eine glatte Oberfläche auf. Textile Fasern hingegen sind rauh. Daher wurden bis jetzt solche Verbundgarne gezwirnt, was eine besonder Art mechanischer Bindung von metallischem und textilem Anteil ergibt. Beim neuen erfindungsgemässen Verfahren nun wird ein im Prinzip endloser elektrisch leitender monofiler Metallfaden direkt mit textilen Fasern in einem Arbeitsgang versponnen, was eine ganz andere Art der Bindung von metallischem und textilem Anteil ergit und zu einem Garn mit wesentlich anderen Eigenschaften führt. Dabei wird einerseits der elektrisch leitende monofile Metallfaden zentrisch einer Ringspinnmaschine zugeführt. Gleichzeitig wird der Anteil aus textilen Fasern als Vorgarn oder Lunte seitlich des Metallfadens zugeführt. In der Ringspinnmaschine werden nun der Metallfaden und die Lunte zusammen zu einem Verbundgarn versponnen. Der Metallfaden bleibt somit immer annähernd zentrisch in der Mitte des Garnes. Ausserordentlich wichtig ist dabei, dass der Metallfaden während dem Spinnvorgang unter annähernd konstanter minimaler Spannung, respektive mindestens annähernd spannungslos gehalten wird. Dazu wird die Ringspinnmaschine mit den notwendigen Zugkraftsensoren und Servoantrieben und -bremsen ausgerüstet und die Ring/Läufer Kombination muss der Materialien Kombination, den Oberflächen dieser Materialien und der Spinngeschwindigkeit entsprechend angepasst sein. Dadurch ist es möglich, dass der monofile Metallfaden auch während dem Spinnprozess kaum verdreht wird. There have always been special problems in manufacturing Association of textiles with metals. A metal wire or Metal thread always has a smooth surface. Textile Fibers, however, are rough. Therefore, so far Compound yarns twisted, which is a special kind of mechanical Binding of metallic and textile components results. With the new one The method according to the invention now becomes in principle endless electrically conductive monofilament metal thread directly with textiles Spun fibers in one operation, which is quite another Type of binding of metallic and textile components leads to a yarn with significantly different properties. Here becomes the electrically conductive monofilament metal thread fed centrally to a ring spinning machine. At the same time the proportion of textile fibers as roving or sliver on the side of the metal thread fed. Now in the ring spinning machine the metal thread and the fuse together to form a composite yarn spun. The metal thread therefore always remains approximate centered in the middle of the yarn. Is extremely important taking the metal thread under during the spinning process approximately constant minimum tension, or at least is kept almost without tension. For this, the Ring spinning machine with the necessary tensile force sensors and Servo drives and brakes and the ring / rotor Combination must be the combination of materials, the surfaces corresponding to these materials and the spinning speed be adjusted. This makes it possible for the monofilament Metal thread is hardly twisted even during the spinning process.

    Er soll so drehungslos wie möglich bleiben, damit er vor einer späteren Weiterverarbeitung, wie Spulen, Weben, Stricken usw., möglichst wenig mechanisch vorbelastet ist. Das so gesponnene Verbundgarn weist daher einen annähernd drehungslosen, metallischen, endlosen Kern auf. Als textile Fasern können grundsätzlich alle Natur- und Kunstfasern verwendet werden. Allerdings gewährleisten gewisse Fasern eine weniger gute Bindung mit dem Metallfaden. Sehr geeignet für eine derartiges Verbundgarn sind beispielsweise Baumwollfasern. Als elektrisch leitender monofiler Metallfaden wird vorzugsweise eine Faden aus Kupfer oder aus Silber oder aus Kupfer oder Silber enthaltenden Legierungen verwendet. Allerdings sind auch gewisse Legierungen aus Stahl oder Leichtmetall möglich. Der Metallfaden weist einen Durchmesser von etwa 10 bis 30 um auf. Sehr gute Resultate wurden bisher mit einem Metallfaden Durchmesser von 20 bis 25 µm erreicht.It should remain as smooth as possible so that it faces one later processing, such as winding, weaving, knitting, etc., is mechanically preloaded as little as possible. The so spun Composite yarn therefore has an almost rotation-free, metallic, endless core. As textile fibers can basically all natural and synthetic fibers are used. However, certain fibers guarantee a less good one Binding with the metal thread. Very suitable for such a Composite yarns are, for example, cotton fibers. As electric Conductive monofilament metal thread is preferably a thread made of copper or silver or made of copper or silver containing alloys used. However, too certain alloys of steel or light metal possible. Of the Metal thread has a diameter of about 10 to 30 µm. So far, very good results have been obtained with a metal thread Diameter of 20 to 25 microns reached.

    Besondere Beachtung ist beim Verspinnen dem ungleichen Gewichtsanteil von metallischen und textilem Anteil am Garn zu schenken. Bei einem derartigen Garn muss der Metallfaden nur die elektrische Leitfähigkeit gewährleisten. Er hat keine tragende Funktion und muss möglichst flexibel, biegbar und leicht sein. Die Flexibilität muss für die Weiterverarbeitung mindestens annähernd derjenigen von einem normalen Garn entsprechen, damit der gesponnene Faden auch verwebt oder verstrickt werden kann. Daher wird der Metallfaden so dünn und leicht, wie nur irgend möglich gemacht. Dies stellt dafür ganz andere Anforderungen an den Spinnprozess, insbesondere an die Zuführung des Metallfadens und die Zugkraftsteuerung.Particular attention is paid to unequal when spinning Weight share of metallic and textile share in the yarn give. With such a yarn, the metal thread only has to ensure electrical conductivity. He has no load-bearing function and must be as flexible, bendable and be light. The flexibility needs for further processing at least approximately that of a normal yarn correspond so that the spun thread is also woven or can be entangled. Therefore, the metal thread becomes so thin and as easy as possible. This entirely represents other requirements for the spinning process, especially for the Feeding the metal thread and the traction control.

    Dies wird erfindungsgemäss dadurch erreicht, dass der Metallfaden auf möglichst geradem und möglichst kurzen Weg der Spinnstelle zugeführt wird. Der Metallfaden wird mindestens annähernd ohne Vorspannung und mit möglichst wenig Drehung der Spinnstelle zugeführt. Er wird entweder tangential, oder mit kleinem Fadenballon auf konventionelle Art von einer Spule abgezogen. Beim tangentialen Abzug von der Spule wird mit Vorteil der Metallfaden geradlinig von der Spule zur Spinnstelle geführt wird, indem beim Abwickeln der Spule diese der Wicklung entsprechend seitwärts hin und her bewegt wird. Eine noch bessere Art ergibt eine Abzug aus dem Innenbereich einer kernlosen Spule. Da der Abzug möglichst ohne Vorspannung geschehen soll, kann auf eine Fadenbremse verzichtet werden.This is achieved according to the invention in that the Metal thread on the straightest and shortest possible path of Spinning station is fed. The metal thread is at least almost without preload and with as little rotation of the Spinning station fed. It becomes either tangential or with small thread balloon in a conventional way from a spool deducted. When pulling tangentially from the coil, use Advantage of the metal thread rectilinear from the bobbin Spinning station is guided by this when unwinding the spool is moved back and forth according to the winding. An even better way results in a deduction from the interior a coreless coil. Since the trigger is without any preload if possible a thread brake can be dispensed with.

    Damit die Qualität der Bindung von monofilem Metallfaden und Baumwollfasern die zur Weiterverarbeitung des Verbundgarnes gewünschte Qualität erreicht, muss die Lunte gut und homogen vorgestreckt sein und die Baumwollfasern müssen möglichst gleichmässige Faserlänge aufweisen.So that the quality of the binding of monofilament and Cotton fibers for the processing of the composite yarn If the desired quality is achieved, the fuse must be good and homogeneous be stretched out and the cotton fibers must be as possible have uniform fiber length.

    Die Bindung von Metalfaden und textilen Fasern wird zusätzlich durch Beschichten des Metallfadens verbessert. Die erfolgt üblicherweise mit einem Lack. Der Lack wirkt einerseits der Sprödigkeit des Metallfadens entgegen und erhöht zugleich die Oberflächenhaftung und damit die Qualität der Bindung im Verbund von Metallfaden und textilen Fasern. Damit wird gerade ein weiteres Problem gelöst. Nämlich das Problem der Gefahr von Katalyt-Schäden im Verbundgarn selbst und durch dieses verursacht an Maschinenelementen. Das Beschichten des Metalfladens hilft zudem Oxidation und Katalyt-Schäden zu verhindern oder mindestens die Gefahren dazu zu vermindern.The binding of metal thread and textile fibers is additional improved by coating the metal thread. That takes place usually with a varnish. The paint on the one hand Towards brittleness of the metal thread and at the same time increases the Surface adhesion and thus the quality of the bond in the Compound of metal thread and textile fibers. With that is just solved another problem. Namely the problem of the danger of Catalytic damage in the composite yarn itself and through it caused on machine elements. Coating the Metalfladen also helps oxidation and catalytic damage prevent or at least reduce the dangers.

    Zusätzlich kann das Verbundgarn im Bereich hinter der Spinnstelle der Ringspinnmaschine kurzzeitig erwarmt werden. Dabei erweicht die Beschichtung des Metallfadens vorübergehend. Dies macht den Kontakt und die Haftung zwischen diesem und den textilen Fasern inniger, da die Oberfläche der Beschichtung sich den textilen Fasern in der Form etwas anpassen kann und dadurch eine Art Formschlüssigkeit erreichbar ist. Dazu kommt, dass der erwärmte Lack der Beschichtung leicht klebrig wird, was die Bindung weiter verbessert.In addition, the composite yarn in the area behind the The spinning position of the ring spinning machine can be warmed up briefly. The coating of the metal thread temporarily softens. This makes the contact and liability between this and the textile fibers more intimate because of the surface of the coating can adapt somewhat to the shape of the textile fibers and a kind of form fit can be achieved. In addition, that the heated paint of the coating becomes slightly sticky, which further improves the bond.

    In der Figur 1 ist die Herstellung eine Verbundgarnes mit einem elektrisch leitenden metallischen und einem textilen Anteil schematisch dargestellt. Ein elektrisch leitender monofiler Metallfaden 11 wird auf möglichst geradem und kurzem Weg der eigentlichen Spinnstelle 1 einer Ringspinnmaschine zugeführt. Gleichzeitig wird eine Lunte aus textilen Fasern 12 mehrfach vorgestreckt mittels Streckvorrichtungen 21, über eine Zuführeinheit 2 ebenfalls der Spinnstelle 1 der Ringspinnmaschine zugeführt. Der Metallfadens 11 wird annähernd zugkraftlos direkt der Spinnstelle 1 zugeführt. Dies kann durch die Zuführung 4 mit entsprechenden Zugkraftsensoren und Servoeinheit überwacht und gegebenenfalls nachgeregelt werden. In der Ringspinnmaschine werden nun die textilen Fasern der Lunte 12 mit einer Seele bestehend aus dem beschichteten Metallfaden 11 zu einem Verbundgarn 13 versponnen. Ein Abzug 3 sorgt für den Wegtransport des Verbundgarnes 13 und gleichzeitig zur Zugkraftkontrolle für das Verbundgarn mit seiner Seele aus dem monofilen Metallfaden 11. Auch hier ist es wichtig, dass die Zugkraft beim Garnabzug klein bleibt und zwar bis und mit dem anschliessenden Aufspulen, damit der Metallfaden möglichst wenig mechanisch beansprucht wird.In Figure 1, the production is a composite yarn with a electrically conductive metallic and a textile part shown schematically. An electrically conductive monofiler Metal thread 11 is as straight and short as possible actual spinning station 1 fed to a ring spinning machine. At the same time, a fuse made of textile fibers 12 becomes multiple pre-stretched by means of stretchers 21, over a Feed unit 2 also the spinning station 1 of the Ring spinning machine fed. The metal thread 11 becomes approximately fed directly to the spinning station 1 without traction. This can be done by the feed 4 with appropriate tensile force sensors and Servo unit monitored and readjusted if necessary. The textile fibers of the are now in the ring spinning machine Fuse 12 with a soul consisting of the coated Metal thread 11 spun into a composite yarn 13. A deduction 3 ensures that the composite yarn 13 and simultaneously with the tensile force control for the composite yarn his soul from the monofilament metal thread 11. Here too it is it is important that the tensile force remains low when pulling the yarn up to and with the subsequent winding, so that the Metal thread is mechanically stressed as little as possible.

    In der Figur 2 ist ein Querschnitt durch ein gesponnenes Verbundgarn dargestellt. Es besteht aus der Seele 111 des Metallfadens 11 welcher rundum eine dünne Beschichtung 112 aufweist. Um den Metallfaden 11 befinden sich der textile Anteil des gesponnenen Verbundgarnes.In Figure 2 is a cross section through a spun Composite yarn shown. It consists of the soul 111 of the Metal thread 11 which has a thin coating 112 all around having. Around the metal thread 11 are the textile Proportion of spun composite yarn.

    Ein nach diesem Verfahren hergestelltes elektrisch leitendes Verbundgarn lässt sich sehr gut weiterverarbeiten. Es eignet sich ganz besonders zur Herstellung von Geweben annähernd beliebiger Art. Es kann auch zu einem Gestrick verarbeitet werden. Als Gewebe oder als Gestrick wird es bevorzugterweise dort Verwendet, wo elektrostatische oder elektrodynamische Felder abgeschirmt oder sogar abgeleitet werden sollten. Es lässt sich beispielsweise zum Bau von farraday'schen Käfigen oder abgeschirmten und geerdeten Flächen oder Räumen verwenden. Dazu kann man beispielsweise ein dünnes Gewebe oder Gestrick aus derartigem Garn oder auch nur einzelne Verbundgarnstränge in eine Tapete einarbeiten. Ebenso lässt sich eine textile oder papierene Tapete aus einem solchen Gewebe oder Gestrick herstellen, denn dieses kann ja sogar auch gefärbt oder bedruckt werden. Eine weitere Verwendung besteht im Einarbeiten in oder Auftragen von derartigen Garnen, Geweben oder Gestricken auf oder in Wärme- bzw. Schall- Dämmplatten. Diese Tapeten oder Dämmplatten lassen sich somit auch an Erdleitungen anschliessen und erweitern so den Einsatzbereich für diese.An electrically conductive manufactured by this method Composite yarn can be processed very well. It is suitable approximate particularly to the manufacture of fabrics of any kind. It can also be processed into a knitted fabric will. As a fabric or as a knitted fabric, it is preferred Used where electrostatic or electrodynamic Fields should be shielded or even derived. It can be used, for example, to build Farraday cages or shielded and grounded areas or rooms. For example, you can use a thin fabric or knitted fabric from such yarn or even individual composite skeins work into a wallpaper. Likewise, a textile or paper wallpaper from such a fabric or knitted fabric manufacture, because this can even be colored or be printed. Another use is the incorporation in or application of such yarns, fabrics or Knitted on or in thermal or acoustic insulation boards. This Wallpaper or insulation boards can therefore also be used on underground lines connect and expand the area of application for them.
