- the invention relates to a method for coating a yarn, in which the yarn is exposed to a gas phase, from which monomers attach to the surface of the yarn and thereby polymerize.
- Coating methods of this type are generally known, for example, for yarns in the form of monofilaments.
- the monomers deposited from the gas phase form a polymerized thin layer on the surface of a monofilament treated in this way, which forms a very intimate and thus durable bond with the material of the monofilament.
- the thin-film deposition is often carried out by means of a so-called plasma polymerization, which is a vacuum coating process. Due to the low process temperature, this process is particularly well suited for coating plastics.
- the deposited polymer layers can be changed in a wide range by targeted process control and adjusted to a wide variety of requirements. As a result, surfaces and their properties can be constructed that can hardly be achieved with other methods.
- An advantage of plasma polymerization is also to be seen in the fact that the entire process takes place in a closed vacuum chamber and therefore only very small amounts of mostly non-toxic process gases are used and this results in a relatively high degree of environmental compatibility, which also includes good recycling properties, since the layers of only ⁇ m in thickness hardly influence the material behavior during recycling.
- a gas In plasma polymerization, a gas (plasma) is generated that contains free electrons, ions and neutral particles through external excitation with the help of electromagnetic radiation. If this gas is under greatly reduced pressure, only the charged particles, ie essentially the very light electrons, can absorb energy.
- energy is transferred to the molecules due to the collision with the electron.
- the plasma itself is almost at room temperature, the energy of the monomers corresponds to an extremely high temperature, so that they are able to break chemical bonds on the surface of the material to be coated and initiate reactions that normally only take place at high temperatures can expire. In this way, the desired high-temperature effects can be achieved without the coating material being thermally stressed.
- the surface properties of monofilaments treated in this way can be specifically influenced.
- a hydrophobic or hydrophilic monofilament surface can be produced, for example. So dirt-repellent properties can be generated or the attractive forces between a surface and a substrate in contact can be controlled.

- these yarns which consist of at least one core thread running in the longitudinal direction and a large number of short fibers oriented perpendicular thereto, can be successfully and effectively provided with a coating made of a gas fiber.
- This finding is by no means self-evident, since with flock yarn, due to the adhesive connection between the orthogonal short fibers (flock) and the soul, there was a fear of negative effects on the integrity of the yarn.

- the method according to the invention thus allows the production of a yarn which, for example, mimics the self-cleaning properties of the leaves of the lotus plant, the so-called “lotus effect” consisting in the fact that on the one hand a surface has a microstructured shape and therefore is not sufficiently large
- This part of the lotus effect is applied to the yarn according to the method according to the invention realized by the orthogonal short fibers, which give the yarn a "brush structure", whereby - especially in the interwoven state of such a yarn - the possible contact surface for dirt particles is formed only by the end faces of the short fibers (bristles), so that the contact surface is very small.
- the second part of the lotus effect is based on the activation of the surface energy of the microstructured surface, which is made possible by the coating from the gas phase in the method according to the invention.
- This increased surface energy which, due to the coating according to the invention, affects the entire surface of the yarn, brings about a considerable increase in the repulsive effect on dirt particles, for example.
- dirt particles can adhere to the short contact surfaces of the short fibers and are, for example, literally rolled over by water droplets, which cannot penetrate the soul thread due to the repellent properties of the yarn, thereby being carried away and thus removed from the surface.
- Yarns which are produced by the process according to the invention are therefore distinguished by extremely advantageous dirt-repellent properties, which cannot be achieved remotely due to the lack of microstructured surface components in plasma-coated monofilaments according to the prior art.

Description
Verfahren zur Beschichtung eines Garns sowie dadurch hergestelltes textiles FlächengebildeProcess for coating a yarn and textile fabric produced thereby
Die Erfindung betrifft ein Verfahren zur Beschichtung eines Garns, bei dem dieses einer Gasphase ausgesetzt wird, aus der heraus sich Monomere an der Oberfläche des Garn anlagern und dabei polymerisieren.The invention relates to a method for coating a yarn, in which the yarn is exposed to a gas phase, from which monomers attach to the surface of the yarn and thereby polymerize.
Derartige Beschichtungsverfahren sind beispielsweise für Garne in Form von Monofila- menten allgemein bekannt. Die dabei aus der Gasphase heraus angelagerten Monomere bilden auf der Oberfläche eines derart behandelten Monofilaments eine polymerisierte Dünnschicht, die mit dem Material des Monofilaments eine sehr innige und damit haltbare Verbindung eingeht. Häufig wird die Dünnschichtanlagerung im Wege einer sogenannten Plasmapolymerisation durchgeführt, bei der es sich um ein Vakuumbeschichtungsverfahren handelt. Dieses Verfahren ist aufgrund der niedrigen Prozeßtemperatur zum Beschichten von Kunststoffen besonders gut geeignet. Die abgeschiedenen Polymerschichten lassen sich durch eine gezielte Prozeßführung in weiten Bereichen verändern und auf verschiedenste Anforderungen einstellen. Hierdurch lassen sich Oberflächen und deren Eigenschaften konstruieren, die sich mit anderen Verfahren kaum realisieren lassen. Ein Vorteil der Plasmapolymerisation ist auch darin zu sehen, daß der gesamte Prozeß in einer abgeschlossenen Vakuumkammer stattfindet und daher nur sehr geringe Mengen meist ungiftiger Prozeßgase zum Einsatz kommen und hieraus resultiert ein relativ hohes Maß an Umweltverträglichkeit, die auch in guten Recyclingeigenschaften besteht, da die nur μm dicken Schichten das Materialverhalten beim Recycling kaum beeinflussen.Coating methods of this type are generally known, for example, for yarns in the form of monofilaments. The monomers deposited from the gas phase form a polymerized thin layer on the surface of a monofilament treated in this way, which forms a very intimate and thus durable bond with the material of the monofilament. The thin-film deposition is often carried out by means of a so-called plasma polymerization, which is a vacuum coating process. Due to the low process temperature, this process is particularly well suited for coating plastics. The deposited polymer layers can be changed in a wide range by targeted process control and adjusted to a wide variety of requirements. As a result, surfaces and their properties can be constructed that can hardly be achieved with other methods. An advantage of plasma polymerization is also to be seen in the fact that the entire process takes place in a closed vacuum chamber and therefore only very small amounts of mostly non-toxic process gases are used and this results in a relatively high degree of environmental compatibility, which also includes good recycling properties, since the layers of only μm in thickness hardly influence the material behavior during recycling.
Bei der Plasmapolymerisation wird ein Gas (Plasma) erzeugt, das durch äußere Anregung mit Hilfe elektromagnetischer Strahlung freie Elektronen, Ionen und Neutralteilchen enthält. Wenn dieses Gas unter stark verringertem Druck steht, können nur die geladenen Teilchen, d.h. im wesentlichen die sehr leichten Elektronen, Energie aufnehmen. Durch Einbringung spezieller Monomere in ein solches Niederdruckplasma werden auf die Moleküle aufgrund des Zusammenstoßes mit den Elektronen Energien übertragen. Obwohl das Plasma selbst nahezu Raumtemperatur besitzt, entspricht die Energie der Monomere einer extrem hohen Temperatur, so daß sie dazu in der Lage sind, chemische Bindungen an der Oberfläche des zu beschichtenden Materials aufzubrechen und Reaktionen in Gang zu setzen, die normalerweise erst bei hohen Temperaturen ablaufen können. Auf diese Weise können die gewünschten Hochtemperatureffekte erreicht werden, ohne daß es zu einer thermischen Belastung des Beschichtungsgutes kommt. Da nach erfolgter Plasmapolymerisation im wesentlichen nur noch die Eigenschaften der neu abgeschiedenen Polymere Auswirkungen zeigen, lassen sich die Oberflächeneigenschaften derart behandelter Monofilamente gezielt beeinflussen. Je nach Art der eingesetzten Monomere und der gewählten Prozeßparameter läßt sich beispielsweise eine hydrophobe oder hydrophile Monofilamentoberfläche erzeugen. Es lassen sich somit schmutzabweisende Eigenschaften erzeugen oder die Anziehungskräfte zwischen einer Oberfläche und einem damit in Kontakt befindlichen Substrat gezielt steuern. Ein anderer mittels der Plasmabeschichtung erzeugter Effekt besteht beispielsweise in der Verbesserung der Farbechtheit des behandeltenIn plasma polymerization, a gas (plasma) is generated that contains free electrons, ions and neutral particles through external excitation with the help of electromagnetic radiation. If this gas is under greatly reduced pressure, only the charged particles, ie essentially the very light electrons, can absorb energy. By introducing special monomers into such a low-pressure plasma, energy is transferred to the molecules due to the collision with the electron. Although the plasma itself is almost at room temperature, the energy of the monomers corresponds to an extremely high temperature, so that they are able to break chemical bonds on the surface of the material to be coated and initiate reactions that normally only take place at high temperatures can expire. In this way, the desired high-temperature effects can be achieved without the coating material being thermally stressed. Since essentially only after plasma polymerization Even if the properties of the newly deposited polymers show effects, the surface properties of monofilaments treated in this way can be specifically influenced. Depending on the type of monomers used and the process parameters selected, a hydrophobic or hydrophilic monofilament surface can be produced, for example. So dirt-repellent properties can be generated or the attractive forces between a surface and a substrate in contact can be controlled. Another effect produced by means of the plasma coating consists, for example, in improving the color fastness of the treated one
Bekannt ist die Plasmabeschichtung von Garnen bisher nur bei Monofilamenten, mit denen sich zwar textile Flächengebilde für verschiedenste Anwendungsfälle herstellen lassen. Dennoch sind für bestimmte Verwendungszwecke textiler Flächengebilde auch andere Arten von Garnen wünschenswert oder unverzichtbar, so daß die Aufgabe der Erfindung darin besteht, ein Verfahren vorzuschlagen, mit dem sich andere Garne als solche in Monofila- mentform in ihren Oberflächeneigenschaften beeinflussen lassen.Up to now, the plasma coating of yarns has only been known for monofilaments, with which textile fabrics can be manufactured for a wide variety of applications. Nevertheless, other types of yarn are also desirable or indispensable for certain uses of textile fabrics, so that the object of the invention is to propose a method with which yarns other than monofilament yarns can be influenced in their surface properties.
Ausgehend von einem Verfahren der eingangs beschriebenen Art wird diese Aufgabe erfindungsgemäß dadurch gelöst, daß das Garn ein Flockgarn oder Chenillegarn ist.Starting from a method of the type described above, this object is achieved according to the invention in that the yarn is a flock or chenille yarn.
Überraschenderweise hat sich herausgestellt, daß auch diese Garne, die aus mindestens einem in Längsrichtung verlaufenden Seelenfaden und einer Vielzahl von senkrecht hierzu ausgerichteten Kurzfasern bestehen, erfolgreich und wirkungsvoll mit einer Beschichtung aus einer Gasfaser heraus versehen lassen. Diese Erkenntnis ist keineswegs selbstverständlich, da bei Flockgarn aufgrund der klebetechnischen Verbindung zwischen den orthogonalen Kurzfasern (Flock) und der Seele negative Auswirkungen auf die Integrität des Garns zu befürchten waren. Derartige Beeinträchtigungen treten bei dem erfindungsgemäßen Verfahren jedoch nicht auf, so daß sich das mit Hilfe dieses Verfahrens hergestellte Garn zum einem durch spezielle physikalisch-geometrische Eigenschaften in Form einer Oberfläche mit einer Mikro- struktur als auch durch besondere Oberflächeneigenschaften auszeichnet, die durch die Polymerdünnschicht erzeugt werden.Surprisingly, it has been found that these yarns, which consist of at least one core thread running in the longitudinal direction and a large number of short fibers oriented perpendicular thereto, can be successfully and effectively provided with a coating made of a gas fiber. This finding is by no means self-evident, since with flock yarn, due to the adhesive connection between the orthogonal short fibers (flock) and the soul, there was a fear of negative effects on the integrity of the yarn. However, such impairments do not occur in the method according to the invention, so that the yarn produced with the aid of this method is distinguished on the one hand by special physical-geometric properties in the form of a surface with a microstructure and by special surface properties which are produced by the polymer thin layer become.
Das erfϊndungsgemäße Verfahren erlaubt somit die Herstellung eines Garns, das zum Beispiel die Selbstreinigungseigenschaften der Blätter der Lotus-Pflanze nachahmt, wobei der soge- nannte „Lotus-Effekt" darin besteht, daß eine Oberfläche zum einen eine mikrostrukturierte Gestalt besitzt und daher keine hinreichend großen Anhaftstellen für Schmutzpartikel bietet. Dieser Teil des Lotus-Effekts wird bei dem Garn gemäß dem erfindungsgemäßen Verfahren von den orthogonalen Kurzfasern verwirklicht, die dem Garn eine „Bürstenstruktur" verleihen, wobei - insbesondere im verwobenen Zustand eines solchen Garns - die mögliche Kontaktfläche für Schmutzpartikel lediglich von den Stirnseiten der Kurzfasern (Borsten) gebildet wird, so daß die Kontaktfläche denkbar gering ist.The method according to the invention thus allows the production of a yarn which, for example, mimics the self-cleaning properties of the leaves of the lotus plant, the so-called “lotus effect” consisting in the fact that on the one hand a surface has a microstructured shape and therefore is not sufficiently large This part of the lotus effect is applied to the yarn according to the method according to the invention realized by the orthogonal short fibers, which give the yarn a "brush structure", whereby - especially in the interwoven state of such a yarn - the possible contact surface for dirt particles is formed only by the end faces of the short fibers (bristles), so that the contact surface is very small.
Der zweite Teil des Lotus-Effekts beruht auf der Aktivierung der Oberflächenenergie der mikrostrukturierten Oberfläche, die bei dem erfindungsgemäßen Verfahren durch die Beschichtung aus der Gasphase ermöglicht wird. Diese erhöhte Oberflächenenergie, die aufgrund der erfindungsgemäßen Beschichtung die gesamte Oberfläche des Garns betrifft, bewirkt eine erhebliche Steigerung des beispielsweise abstoßenden Effekts auf Schmutz- partikel. Schmutzpartikel können allenfalls an den kleinen stirnseitigen Kontaktflächen der Kurzfasern anhaften und werden beispielsweise von Wassertropfen, die aufgrund der abweisenden Eigenschaften des Garn nicht bis auf den Seelenfaden vordringen können, regelrecht überrollt, dabei mitgenommen und somit von der Oberfläche entfernt.The second part of the lotus effect is based on the activation of the surface energy of the microstructured surface, which is made possible by the coating from the gas phase in the method according to the invention. This increased surface energy, which, due to the coating according to the invention, affects the entire surface of the yarn, brings about a considerable increase in the repulsive effect on dirt particles, for example. At best, dirt particles can adhere to the short contact surfaces of the short fibers and are, for example, literally rolled over by water droplets, which cannot penetrate the soul thread due to the repellent properties of the yarn, thereby being carried away and thus removed from the surface.
Garne, die nach dem erfindungsgemäßen Verfahren hergestellt sind, zeichnen sich daher durch äußerst vorteilhafte schmutzabweisende Eigenschaften aus, wie sie sich aufgrund der fehlenden mikrostrukturierten Flächenkomponenten bei plasmabeschichteten Monofilamenten nach dem Stand der Technik nicht entfernt erzielen lassen.Yarns which are produced by the process according to the invention are therefore distinguished by extremely advantageous dirt-repellent properties, which cannot be achieved remotely due to the lack of microstructured surface components in plasma-coated monofilaments according to the prior art.
Um den erfindungsgemäßen Beschichtungsvorgang auch bei Trägergarnen aus temperaturempfindlichen Werkstoffen durchführen zu können, wird vorgeschlagen, daß die Gasphase ein Vakuum-Plasma ist.In order to be able to carry out the coating process according to the invention even with carrier yarns made of temperature-sensitive materials, it is proposed that the gas phase be a vacuum plasma.
Zur Erzielung einer besonders schmutzabweisenden Eigenschaft wird vorgeschlagen, daß als Monomere die Stoffe Fluorkarbone verwendet werden.In order to achieve a particularly dirt-repellent property, it is proposed that the substances fluorocarbons be used as monomers.
Die Erfindung umfaßt des weiteren ein Flockgarn oder Chenillegarn oder ein ähnliches Garn mit radial ausgerichteten Kurzfasern, das dadurch gekennzeichnet ist, daß seine Oberfläche mit einer aus einer Gasphase heraus aufgebrachten polymerisierten Dünnschicht aus einem Monomer versehen ist.The invention further comprises a flock or chenille yarn or similar yarn with radially oriented short fibers, which is characterized in that its surface is provided with a polymerized thin layer of a monomer applied from a gas phase.
Die besonders schmutzabweisenden Eigenschaften eines derartigen Garns werden dadurch erzielt, daß beide Komponenten des in der Natur vorkommenden „Lotus-Effekts" nachgebildet werden, und zwar sowohl die mikrostrukturierte Oberfläche durch die radial ver- laufenden Kurzfasern als auch die durch die Dünnschicht erreichte Oberflächenaktivierung. Alternativ schlägt die Erfindung ein Flockgarn oder Chenillegarn vor, das dadurch gekennzeichnet ist, daß die Oberfläche eines Garn, aus dem die ungefähr radial zu der Längsachse des Trägergarns verlaufenden Kurzfasern gebildet werden, vor seiner Verbindung mit dem Trägergarn mit einer aus einer Gasphase heraus aufgebrachten polymerisierten Dünnschicht versehen ist.The particularly dirt-repellent properties of such a yarn are achieved in that both components of the "lotus effect" occurring in nature are reproduced, namely both the microstructured surface by the radially extending short fibers and the surface activation achieved by the thin layer. Alternatively, the invention proposes a flock or chenille yarn, which is characterized in that the surface of a yarn, from which the short fibers extending approximately radially to the longitudinal axis of the carrier yarn are formed, prior to its connection to the carrier yarn with a polymerized from a gas phase Thin layer is provided.
Hierbei kann entweder vor der Verbindung von Trägergarn und Kurzfasern eine separate Plasmabeschichtung des Trägergarns durchgeführt werden, oder aber es wird auf diesen Schritt verzichtet, wodurch sich die schmutzabweisenden Eigenschaften des erhaltenen Flockgarn oder Chenillegarns je nach Anwendungsfall kaum ändern, da die Schmutzpartikel den Bereich des Trägergarns aufgrund der abstoßenden Wirkung der radialen Kurzfasern ohnehin kaum erreichen können.Here, either a separate plasma coating of the carrier yarn can be carried out before the connection of carrier yarn and short fibers, or this step is omitted, as a result of which the dirt-repellent properties of the flock yarn or chenille yarn obtained hardly change depending on the application, since the dirt particles affect the area of the carrier yarn can hardly reach anyway due to the repulsive effect of the radial short fibers.
Vorteilhafterweise handelt es sich bei der Gasphase um ein Vakuumplasma, in das wiederum vorzugsweise Monomere in Form von Fluorkarbonen eingebracht werden.The gas phase is advantageously a vacuum plasma, into which monomers in the form of fluorocarbons are preferably introduced.
Gegenstand der Erfindung ist außerdem ein textiles Flächengebilde, das einen wesentlichen Anteil eines Flockgarns oder Chenillegarns, wie es zuvor beschrieben wurde, enthält.The invention also relates to a textile fabric which contains a substantial proportion of a flock or chenille yarn, as described above.
Eine besonders vorteilhafte Anwendung eines derartigen textilen Flächengebildes besteht darin, daß es als Papiermaschinenbespannung, beispielsweise als Trockensieb einer Papiermaschine, verwendet wird. Hier sind die hervorragenden schmutzabweisenden Eigenschaften eines derartigen Flächengebildes, beispielsweise in Form eines Gewebes, besonders er- wünscht, da die Verschmutzungsproblematik, insbesondere mit dem stetig ansteigenden Altpapieranteil bei der Papierherstellung, zunehmende Bedeutung bekommt.A particularly advantageous application of such a textile fabric is that it is used as paper machine clothing, for example as a dryer fabric of a paper machine. The excellent dirt-repellent properties of such a fabric, for example in the form of a fabric, are particularly desirable here, since the problem of soiling, in particular with the steadily increasing proportion of waste paper in paper production, is becoming increasingly important.
