Abstract
Description
Die Erfindung betrifft ein Fasergarn, ein Verfahren zum Herstellen eines solchen Garns, ein Verfahren zum Herstellen eines Gefüges und ein Gefüge.The invention relates to a fiber yarn, a method for producing such Yarn, a process for making a structure and a structure.
In vielen industriellen Bereichen, insbesondere in der Textilindustrie, stellt sich regelmäßig die Aufgabe, Fasergarne miteinander oder mit anderen Werkstoffen zu einem Gefüge zu verarbeiten, beispielsweise zu einem Gewebe, Geflecht, Gewirk, Gestrick oder Gelege.In many industrial areas, especially in the textile industry regularly do the job of fiber yarns with each other or with others To process materials into a structure, for example into a fabric, Braid, knitted fabric, knitted fabric or scrim.
Fasergarne liegen dabei üblicherweise als durch Spinnverfahren aus Kapillarfasem hergestellte fadenförmige Erzeugnisse vor. Die Kapillarfasern können ein Bündel extrem langer gesponnener Fasern sein; sie können jedoch auch gerissen oder gekürzt sein und zu einem Garn verarbeitet, beispielsweise verdrillt, sein. Meist sind Fasergarne aus vielen verdrillten Kapillarfasem hergestellt, wobei durch den Kapillarfaserdurchmesser, die Kapillarfaserlänge und die Art der Verdrillung oder Nachbehandlung des Garnes Fasergarne mit unterschiedlichen Eigenschaften hergestellt werden können.Fiber yarns are usually spun from capillary fibers manufactured thread-like products. The capillary fibers can be a bundle of extremely long spun fibers; however, they can also be torn or shortened and processed into a yarn, for example twisted to be. Mostly, fiber yarns are made from many twisted capillary fibers manufactured, whereby by the capillary fiber diameter, the capillary fiber length and the type of twisting or post-treatment of the yarn can be manufactured with different properties.
Zur textilen Verarbeitung finden vielfältigste Methoden Anwendung, von denen hier beispielhaft das Weben betrachtet werden soll. Das Verweben von Fasergarnen wird in größten industriellen Maßstäben durchgeführt, kann Fasergarne aus diversen Materialien verwenden und bringt nicht nur Stoffe für den täglichen Bedarf hervor, sondern kann auch Spezialgewebe erzeugen, so beispielsweise Metallgewebe zur Tiefenfiltration von Fluiden. A wide variety of methods are used for textile processing, from which weaving should be considered here as an example. The weaving of fiber yarns is carried out on the largest industrial scale, can Use fiber yarns from various materials and not only brings fabrics for everyday needs, but can also produce special fabrics, for example metal mesh for deep filtration of fluids.
Leider sind die Fasergarne häufig schwierig zu verarbeiten. In Folge ihrer multifilen Struktur aus einer Vielzahl von unabhängigen Kapillarfasem haben die Fasergarne teilweise einen nur geringen Zusammenhalt.Unfortunately, the fiber yarns are often difficult to process. As a result of her have multifilament structure from a variety of independent capillary fibers some of the fiber yarns have little cohesion.
Vor allem bei Kapillarfasem, die nur wenig verdrillt sind, stellen sich oft unerwünschte Effekte ein. Beispielsweise können die Enden der Kapillarfasem aus dem Fasergarn herausragen. Auch können sich die Kapillarfasern spreizen und hierdurch den Durchmesser des Fasergarns vergrößern. Beim Einweben als Schuss in ein Webgefüge können hierdurch einzelne Kapillarfasem an Kettfäden oder der Webvorrichtung entlang streifen und hierdurch beschädigt werden, womit eine strukturelle Schwächung des Fasergarns einhergeht.Capillary fibers, which are only slightly twisted, often arise undesirable effects. For example, the ends of the capillary fibers protrude from the fiber yarn. The capillary fibers can also spread and thereby enlarge the diameter of the fiber yarn. At the Individual capillary fibers can be woven into a weave structure as a weft Brush along warp threads or the weaving device and thereby be damaged, which is accompanied by a structural weakening of the fiber yarn.
Der Erfindung liegt die Aufgabe zu Grunde, die beschriebenen Schwierigkeiten bei der Verarbeitung von polyfilem Fasergarn weitestgehend zu reduzieren oder sogar aus der Welt zu schaffen.The invention is based on the problem, the difficulties described to reduce as far as possible when processing polyfilem fiber yarn or even get rid of the world.
Diese Aufgabe löst mit beeindruckender Simplizität ein Fasergarn mit einer Vielzahl von Kapillarfasem, wenn das Fasergarn mit einem Wickelfaden umwunden ist.This task solves a fiber yarn with an impressive simplicity Variety of capillary fibers when the fiber yarn with a winding thread is wound.
Der Wickelfaden ist dabei vorzugsweise ein langer Faden, welcher um sämtliche Kapillarfasem des Fasergarns herumläuft. Durch den Wickelfaden werden die Kapillarfasem so zusammengehalten, dass sie auch unter verschiedenen Krafteinwirkungen, zumindest aber unter Eigengewicht, ihren Zusammenhalt behalten. Der Wickelfaden kann dabei sogar eine Vorspannung auf die Kapillarfasem ausüben, wobei die Vorspannung sowohl in radialer Richtung des Fasergarns oder sogar in dessen Längserstreckungsrichtung wirken kann.The winding thread is preferably a long thread, which around all Capillary fiber of the yarn runs around. Through the winding thread the capillary fibers are held together in such a way that they can also be Effects, at least under their own weight, their Keep together. The winding thread can even be pretensioned exert on the capillary fibers, the pretension both in radial Direction of the fiber yarn or even in its longitudinal direction can work.
Durch den verlässlichen Zusammenhalt der Kapillarfasem ist das Fasergarn einfacher zu verarbeiten. Dies trifft sowohl für den Hersteller des Fasergarns als auch für denjenigen zu, der das Fasergarn zu einem Gefüge verarbeitet.Due to the reliable cohesion of the capillary fibers, the fiber yarn easier to process. This applies to both the manufacturer of the fiber yarn as well as for those who process the fiber yarn into a structure.
Die erfindungsgemäße Umwindung mit einem Wickelfaden bringt insbesondere dann große Vorteile, wenn die Kapillarfasem eigensteif sind. Unter eigensteifen Kapillarfasern seien dabei solche Kapillarfasern verstanden, welche in vertikaler, einseitiger Einspannung bei einer Kraglänge von 1 mm eine Knicklast von mindestens 0,01 N haben. Der Grad der Eigensteifigkeit bestimmt sich überwiegend nach dem Material der Kapillarfaser und nach ihrer Geometrie im Querschnitt.The winding according to the invention with a winding thread brings in particular then great advantages if the capillary fibers are inherently rigid. Under rigid Capillary fibers are understood to mean those capillary fibers which in vertical, one-sided clamping with a cantilever length of 1 mm Have a buckling load of at least 0.01 N. The degree of inherent rigidity determines mainly according to the material of the capillary fiber and its Cross-sectional geometry.
Eigensteife Fasern können eine nicht unerhebliche Knicklast aufnehmen, sodass sich bei der Verarbeitung eines Fasergarns mit einer auskragenden eigensteifen Kapillarfaser besondere Probleme ergeben können. Beispielsweise können beim Einweben eines Fasergarns mit einem solchen auskragenden Kapillarfaserende am Schussfaden leicht die Kettfäden beschädigt werden. Unter Umständen kann sich der Schussfaden sogar verhaken und festsetzen.Rigid fibers can absorb a not inconsiderable buckling load, so that when processing a fiber yarn with a cantilever intrinsically stiff capillary fibers can result in special problems. For example can with a cantilever when weaving a fiber yarn Capillary fiber end on the weft thread slightly damaged the warp threads become. Under certain circumstances, the weft thread can even get caught and fix.
Die Anwendung der Erfmdung bei einem Fasergarn mit eigensteifen Kapillarfasem bewirkt daher einen besonders großen Zuwachs in der Betriebssicherheit bei der Verarbeitung des Fasergarns. Eigensteife Kapillarfasem lassen sich zudem mit einem erfindungsgemäßen Wickelfaden besonders gut zusammenhalten. Dies gilt insbesondere dann, wenn die Kapillarfasern zumindest überwiegend metallen sind.The application of the invention to a fiber yarn with inherently rigid capillary fibers therefore causes a particularly large increase in operational safety when processing the fiber yarn. Let the stiff capillary fibers is also particularly good with a winding thread according to the invention stick together. This applies in particular if the capillary fibers at least are predominantly metals.
Von besonderem Vorteil ist die Erfindung auch bei einer sehr großen Anzahl von Kapillarfasem im Fasergarn, insbesondere bei mehr als 100, vorzugsweise mehr als 500, Kapillarfasern. Bei einer so hohen Anzahl ist auch die Wahrscheinlichkeit herauskragender Faserspitzen sehr hoch. Entsprechend groß ist der Nutzen der vorliegenden Erfmdung für diese Anwendung.The invention is particularly advantageous even with a very large number of capillary fibers in the fiber yarn, in particular at more than 100, preferably more than 500, capillary fibers. With such a large number, that is too Very high probability of protruding fiber tips. Corresponding the benefit of the present invention is great for this application.
Eine vergleichbare Bereicherung bringt die Erfmdung auch dann, wenn die Kapillarfasern einen Durchmesser von weniger als 100 µm, vorzugsweise weniger als 30 µm, haben. Ein Fasergarn, welches aus Kapillarfasern einer solchen Feinheit zusammengesetzt ist, weist oft fehlerhafte Stellen auf, da solch feine Kapillarfasern sehr verletzlich sind. Insbesondere können sie schnell reißen oder anderweitig durchtrennt werden, sodass die beschriebenen Probleme beim herkömmlichen Verarbeiten des Fasergarns leicht auftreten können.The invention brings a comparable enrichment even if the Capillary fibers less than 100 microns in diameter, preferably less than 30 µm. A fiber yarn made from capillary fibers such a fineness is often faulty, because such fine capillary fibers are very vulnerable. In particular, they can tear quickly or are otherwise severed so that the described Problems with conventional processing of the fiber yarn easily occur can.
In einer Ausführungsform der Erfindung weist der Wickelfaden eine andere Struktur auf als die Kapillarfasern. Unter Struktur sei hier insbesondere das Material verstanden, aber auch die Dicke des Wickelfadens oder dessen Querschnittsform können anders ausgebildet sein. Beispielsweise kann beim Verarbeiten eines Fasergarns mit sehr hochwertigen Kapillarfasern unter vielen Umständen auch ein kostengünstiger Wickelfaden zum Einsatz kommen. In one embodiment of the invention, the winding thread has a different one Structure on than the capillary fibers. Under structure here is in particular Understood material, but also the thickness of the winding thread or its Cross-sectional shape can be designed differently. For example, at Processing a fiber yarn with very high quality capillary fibers among many Under certain circumstances, an inexpensive winding thread can also be used.
Generell ist es in den meisten Fällen anzustreben, dass ein möglichst kostengünstiger, sicher zu verarbeitender Wickelfaden verwendet wird. Dies kann beispielsweise dadurch gewährleistet werden, dass der Wickelfaden monofil ist. Ein monofiler Faden lässt sich sehr zuverlässig verarbeiten.In general, the aim in most cases should be that a winding thread that can be safely processed is used. This can can be ensured, for example, that the winding thread is monofilament is. A monofilament thread can be processed very reliably.
Um dem Wickelfaden eine hohe Festigkeit zu geben, kann vorgesehen sein, dass der Wickelfaden metallen ist. Beispielsweise kann er aus zwei verdrillten Metallfasern oder aus einem Metalldraht bestehen.In order to give the winding thread high strength, it can be provided that that the winding thread is metal. For example, it can be twisted from two Metal fibers or consist of a metal wire.
Sehr gute Ergebnisse in Bezug auf Verarbeitbarkeit, Haltbarkeit und Festigkeit werden für die meisten Fasergarne erreicht, wenn der Wickelfaden einen Durchmesser zwischen 10 µm und 50 µm hat. Dies trifft insbesondere für metallene Wickelfäden zu.Very good results in terms of workability, durability and strength are achieved for most fiber yarns when the winding thread Has a diameter between 10 microns and 50 microns. This is particularly true for metallic winding threads too.
In einer Ausfühnmgsform der Erfindung hat der Wickelfaden eine geringere physikalische und/oder chemische Beständigkeit als die Kapillarfasern. Hierdurch wird es insbesondere ermöglicht, den Wickelfaden nach Einbringen des Fasergarns in das Gefüge zu entfernen. Beispielsweise kann der Wickelfaden aus Kunststoff sein, während die Kapillarfasem aus Metall sind; dann kann der Wickelfaden nach dem Einbringen weggesclnnolzen oder weggeätzt werden.In one embodiment of the invention, the winding thread has a smaller one physical and / or chemical resistance than the capillary fibers. This in particular makes it possible to insert the winding thread after it has been introduced to remove the fiber yarn into the structure. For example, the winding thread be made of plastic, while the capillary fibers are made of metal; then the winding thread can be tucked away after insertion or be etched away.
Insbesondere zum Einsatz in der Lebensmitteltechnik bietet es sich jedoch an, dass die Kapillarfasern und/oder der Wickelfaden aus Edelstahl bestehen. However, it is particularly suitable for use in food technology indicates that the capillary fibers and / or the winding thread are made of stainless steel.
Unabhängig hiervon kann der Wickelfaden vorteilhaft eine Steighöhe zwischen 7 mm und 1000 mm haben. Umfangreiche Versuche mit verschiedensten Kapillarfasern haben ergeben, dass die meisten Fasergarne die zugrundeliegende Aufgabe in besonders hohem Maße lösen, wenn sie dergestalt umwunden sind.Regardless of this, the winding thread can advantageously have a climbing height between Have 7 mm and 1000 mm. Extensive tests with various Capillary fibers have shown that most fiber yarns are the underlying Solve the task to a particularly high degree if it wraps around in this way are.
In einer besonders bevorzugten Ausführungsform der Erfmdung weist das Fasergarn einen zweiten Wickelfaden auf, der das Fasergarn vorzugsweise gegenläufig zum ersten Wickelfaden umläuft. Hierdurch kann nicht nur bei großer Steighöhe des Wickelfadens bzw. der Wickelfäden eine große Festigkeit der Kapillarfasern erreicht werden. Vielmehr wird auch die Betriebssicherheit deutlich erhöht, da das Fasergarn auch bei Reißen eines Wickelfadens seine Festigkeit nicht oder nur teilweise verliert. Selbstverständlich kann auch eine über zwei hinausgehende Anzahl von Wickelfäden den grundlegenden Erfindungsgedanken umsetzen.In a particularly preferred embodiment of the invention, this Fiber yarn on a second winding thread, which preferably the fiber yarn runs counter to the first winding thread. This can not only at high rise height of the winding thread or winding thread a great strength of capillary fibers can be reached. Rather, operational security also significantly increased because the fiber yarn even when a winding thread breaks does not lose its strength or only partially. Of course can also have a number of winding threads exceeding two implement fundamental ideas of the invention.
Die gestellte Aufgabe wird ebenfalls durch ein Verfahren zum Herstellen des vorstehend beschriebenen Fasergarns gelöst, bei welchem zunächst die Kapillarfasern zu dem Fasergarn gesponnen werden und das Fasergarn anschließend mit einem Wickelfaden umwunden wird. Dies ist eine einfache Art, ein vorteilhaft umwundenes Fasergarn herzustellen.The task is also achieved by a method for producing the Solved fiber yarn described above, in which first the capillary fibers be spun into the fiber yarn and then the fiber yarn is wrapped with a winding thread. This is an easy one Way to produce an advantageously wound fiber yarn.
Für den Fall, dass ein Fasergarn zwar unter Nutzung der vorliegenden Erfindung in ein Gefüge eingearbeitet werden soll, anschließend jedoch der Wickelfaden in der Struktur des Gefüges eine Störung verursachen würde, wird ein Verfahren zum Herstellen eines Gefüges unter Verwendung eines Fasergarns mit einer Vielzahl von Kapillarfasern - insbesondere in der vorstehend beschriebenen Ausgestaltung - vorgeschlagen, bei welchem das Fasergarn zunächst umwunden von einem Wickelfaden in das Gefüge eingearbeitet wird und anschließend der Wickelfaden entfernt wird.In the event that a fiber yarn using the present invention to be worked into a structure, but then the winding thread would cause a disruption in the structure of the structure a method of manufacturing a structure using a fiber yarn with a variety of capillary fibers - especially in the above described configuration - proposed, in which the fiber yarn first wound into the structure by a winding thread and then the winding thread is removed.
Wie bereits erläutert, können hierfür beispielsweise Wickelfäden aus Kunststoff verwendet werden, die thermisch oder chemisch aus dem Gefüge gelöst werden. Eine weitere Möglichkeit liegt beispielsweise darin, dass beiderseits des Gefüges der Wickelfaden ergriffen und/oder gehalten und durch Aufbringen einer Zugkraft zerrissen wird. Insbesondere bei einer großen Steighöhe des Wickelfadens bietet es sich sogar an, den Wickelfaden auf einer Seite des Gefüges zu ergreifen und schlichtweg herauszuziehen. Das Entfernen des Wickelfadens kann dabei zu einem beliebigen Zeitpunkt zwischen dem Einbringen des jeweiligen Fasergarns und dem Fertigstellen des Gefüges erfolgen.As already explained, plastic winding threads can be used for this are used, which are thermally or chemically released from the structure become. Another possibility, for example, is that on both sides the structure of the winding thread is gripped and / or held and by application a tensile force is torn. Especially with a high rise of the winding thread, it even lends itself to the winding thread on one Grasp the side of the structure and simply pull it out. The removal of the winding thread can at any time between the introduction of the respective fiber yarn and the completion of the structure respectively.
Besonders großen Vorteil erreicht dieses vorgeschlagene Verfahren dann, wenn das herzustellende Gefüge ein Gewebe ist und das Fasergarn als Schussfaden eingebracht wird. Das Fasergarn kann dadurch geschützt ins Gewebe eingebracht werden und hat im Idealfall keine Knickstellen, die das Garn partiell übermäßig komprimieren können. Auch bildet das umwundene Fasergarn eine relativ glatte Oberfläche, die den Webvorgang erleichtert.This proposed method achieves a particularly great advantage, if the structure to be produced is a woven fabric and the fiber yarn as Weft thread is introduced. The fiber yarn can thus be protected Tissue are introduced and ideally has no kinks that the Partially compress yarn excessively. Also forms the wrapped Fiber yarn has a relatively smooth surface that makes weaving easier.
Insbesondere gewebte Gefüge können daher unter Nutzung des vorgeschlagenen Fasergarns sehr betriebssicher hergestellt werden. In particular, woven structures can therefore be used using the proposed Fiber yarns are manufactured very reliably.
Es sei erwähnt, dass sämtliche vorteilhaften erwähnten Merkmale auch für sich gesehen vorteilhaft und erfinderisch sind, sofern sie sich nicht explizit nur auf vorangegangene vorteilhafte Merkmale beziehen.It should be mentioned that all advantageous features mentioned also for seen to be advantageous and inventive unless they are explicit only refer to previous advantageous features.
