Abstract

The fabric has a netting partially or completely formed from smooth filament yarns, where the fabric has a color changing effect. Warp threads and weft threads form the netting, and are formed from polymer e.g. polyacrylnitrile. The warp threads and the weft threads are spinning nozzle-colored, and have different colors, which produce a color of the netting. The color of the netting varies based on a viewing angle. The warp threads and weft threads are designed as multifilaments, and have different finenesses. The multifilaments are formed from 180 to 220 individual filaments.

Description

Die Erfindung betrifft ein textiles Flächengebilde mit einem Gewebe, das teilweise oder ganz aus glatten Filamentgarnen aufgebaut ist, wobei Kettfäden und Schussfäden das Gewebe bilden und wobei die Kettfäden und die Schussfäden jeweils aus einem Polymer bestehen.The invention relates to a textile fabric with a fabric which is partially or wholly composed of smooth filament yarns, wherein warp threads and weft threads form the fabric and wherein the warp threads and the weft threads each consist of a polymer.

Des Weiteren betrifft die Erfindung eine Verwendung eines derartigen Flächengebildes.Furthermore, the invention relates to a use of such a sheet.

Schließlich betrifft die Erfindung eine Vorrichtung mit zumindest einem Antrieb und zumindest einem textilen Flächengebilde, wobei das textile Flächengebilde durch den Antrieb verfahrbar ist.Finally, the invention relates to a device with at least one drive and at least one textile fabric, wherein the textile fabric can be moved by the drive.

Textile Flächengebilde sollen für spezielle Anwendungen, beispielsweise Verdecke von Cabriolets oder Markisen, eine anmutige Oberfläche erzeugen. Das sogenannte Dessin soll höchsten Ansprüchen gerecht werden, insbesondere bei Anwendungen im Hochpreissegment. Gleichzeitig ist allerdings eine Langlebigkeit gefordert, da entsprechende textile Flächengebilde oftmals im Außenbereich zur Anwendung kommen bzw. eingesetzt werden und daher verschiedenen Einflüssen unterliegen, welche das textile Flächengebilde unerwünscht rasch beeinträchtigen können, sodass die ehemalige Anmutigkeit der Oberfläche verloren geht. Hierzu zählen insbesondere Witterungseinflüsse, Einflüsse durch Ozon sowie Einflüsse durch Sonnenbestrahlung bzw. UV-Licht.Textile fabrics are intended to create a graceful surface for special applications such as cabriolet or awning tops. The so-called design should meet the highest demands, especially for high-price applications. At the same time, however, a longevity is required, since corresponding textile fabrics are often used or used outdoors and therefore subject to various influences, which can affect the fabric undesirable quickly, so that the former grace of the surface is lost. These include in particular weather influences, influences by ozone as well as influences by solar irradiation or UV light.

Aus dem Stand der Technik sind verschiedene textile Flächengebilde, beispielsweise für Cabriolets, bekannt geworden. Unter anderem offenbart die DE 20 2010 003 899 U1 einen flexiblen Verdeckbezug für ein Verdeck eines Cabriolets, wobei das Gewebe zumindest bereichsweise mit einer panamaartigen oder zickzackkörperartigen Gewebebindung ausgebildet ist, die zu einer Carbonoptik führen soll. Dies soll einen hochwertigen, edlen optischen Eindruck bewirken. Vorgesehen sein kann auch, dass als Materialen Polyacrylnitrile (PAN) eingesetzt werden und Kettfäden und Schussfäden verschiedene Farben aufweisen, um die Erzielung eines Carboneffektes zu vereinfachen. Aus der DE 39 25 893 C2 ist ein textiles Flächengebilde bekannt geworden, das ebenfalls mit Kettfäden und Schussfäden aus unterschiedlichen Farbtönen ausgebildet sein kann, wobei das Kettgarn und das Schussgarn aus einer Farbkombination, hervorgerufen durch unterschiedlich gefärbte Einzelfilamente, bestehen können.Various textile fabrics, for example for convertibles, have become known from the prior art. Among other things, the DE 20 2010 003 899 U1 a flexible top cloth for a hood of a convertible, wherein the fabric is at least partially formed with a panama-like or zigzag body-like weave, which should lead to a carbon look. This should cause a high-quality, noble optical impression. It can also be provided that polyacrylonitriles (PAN) are used as materials and warp threads and weft threads have different colors in order to simplify the achievement of a carbon effect. From the DE 39 25 893 C2 a textile fabric has become known, which can likewise be formed with warp threads and weft threads of different color shades, wherein the warp yarn and the weft yarn can consist of a color combination caused by differently dyed individual filaments.

Aus der DE 10 2006 004 681 A1 ist ein Garngewebe bekannt geworden, das in Jacquard-Webtechnik erzeugbar ist, wobei Fasern eingesetzt werden, die unterschiedliche Farben aufweisen. Dadurch soll erreicht werden, dass gegenüber dem Stand der Technik mehrere Farbvarianten des Garngewebes neben einer Farbechtheit desselben gegeben sind.From the DE 10 2006 004 681 A1 has become known a yarn fabric which can be produced in Jacquard weaving technique, wherein fibers are used which have different colors. This is intended to achieve that over the prior art several color variants of the yarn fabric are given in addition to a color fastness of the same.

In der DE 10 2008 022 577 A1 ist ein Cabriolet mit einem Verdeck offenbart, wobei dem Gewebe Schussfäden in unterschiedlichen Farben zugeordnet sind. Ein Teil der Schussfäden ist in einer dunklen Grundfarbe und ein anderer Teil der Schussfäden in einer Kontrastfarbe hierzu ausgebildet. Durch diesen Wechsel soll eine optische Anmutung verbesserbar sein.In the DE 10 2008 022 577 A1 discloses a convertible with a hood, wherein the fabric weft threads are assigned in different colors. A part of the weft threads is formed in a dark ground color and another part of the weft threads in a contrasting color thereto. By this change, an optical appearance should be able to be improved.

In der DE 20 18 019 B2 ist die Herstellung eines Mischgarns aus Garnkomponenten offenbart, die mit Zweifarben-Charakter ausgebildet sind. Durch die homogene Mischung der Garnkomponenten bzw. in diesen soll eine einwandfreie Verteilung der Fäden über den gesamten Querschnitt eines Mischgarnes erreicht und somit die Erzielung einer ansprechenden Melange gegeben sein.In the DE 20 18 019 B2 discloses the production of a blended yarn of yarn components formed with a two-color character. Due to the homogeneous mixing of the yarn components or in these a perfect distribution of the threads over the entire cross-section of a mixed yarn is to be achieved and thus the achievement of an appealing melange.

In der DE 39 00 846 A1 ist ein Gewebe aus PAN offenbart, wobei die Kettfäden und die Schussfäden als Multifilamente vorliegen können.In the DE 39 00 846 A1 discloses a fabric of PAN, wherein the warp threads and the weft threads may be present as multifilaments.

Im Rahmen der gegenständlichen Erfindung wurde erkannt, dass bei einem textilen Flächengebilde der eingangs genannten Art eine besonders anmutige Erscheinungsform erreicht werden kann, die zugleich langlebig ist, wenn die Kettfäden und die Schussfäden spinndüsengefärbt sind und unterschiedliche Farben aufweisen, die eine von einem Betrachtungswinkel abhängige variierende Farbe des Gewebes ergeben. Insbesondere wird durch Kettfäden und Schussfäden unterschiedlicher Farbe bei einem textilen Flächengebilde der eingangs genannten Art ein optischer Kippeffekt erreicht, d. h., dass sich die Farbe des textilen Flächengebildes optisch anmutig je nach Betrachtungswinkel ändert.In the context of the present invention it has been recognized that in a textile fabric of the type mentioned a particularly graceful appearance can be achieved, which is durable at the same time when the warp threads and the weft yarns are spinneret dyed and have different colors, the one dependent on a viewing angle varying Color of the fabric result. In particular, an optical tilting effect is achieved by warp threads and weft threads of different color in a textile fabric of the type mentioned in the introduction, ie, that the color of the fabric changes optically graceful depending on the viewing angle.

Dementsprechend ist es eine Aufgabe der Erfindung, ein textiles Flächengebilde der eingangs genannten Art anzugeben, das eine langzeitstabile optisch anmutige Oberfläche mit variierender Farbe ergibt.Accordingly, it is an object of the invention to provide a textile fabric of the type mentioned, which results in a long-term stable optically graceful surface with varying color.

Eine weitere Aufgabe der Erfindung ist es, eine Verwendung eines derartigen textilen Flächengebildes darzustellen.Another object of the invention is to illustrate a use of such a textile fabric.

Schließlich ist es Aufgabe der Erfindung, eine Vorrichtung der eingangs genannten Art anzugeben, die mit einem optisch anmutigen, langzeitstabilen textilen Flächengebilde ausgebildet ist.Finally, it is an object of the invention to provide a device of the type mentioned, which is formed with an optically graceful, long-term stable textile fabric.

Die erste Aufgabe der Erfindung wird erfindungsgemäß dadurch gelöst, dass bei einem textilen Flächengebilde der eingangs genannten Art die Kettfäden und die Schussfäden spinndüsengefärbt sind und unterschiedliche Farben aufweisen, die eine von einem Betrachtungswinkel abhängige variierende Farbe des Gewebes ergeben.The first object of the invention is achieved in that, in a textile fabric of the type mentioned above, the warp threads and the weft threads are spinneret dyed and have different colors which result in a varying color of the fabric depending on a viewing angle.

Ein mit der Erfindung erzielter Vorteil ist darin zu sehen, dass ein optisch anmutiges, auch bei Witterungseinflüssen langzeitstabiles textiles Flächengebilde bereitgestellt wird. Dabei kommt es darauf an, dass das textile Flächengebilde zumindest teilweise aus glatten Filamentgarnen gebildet ist und sowohl die Kettfäden als auch die Schussfäden spinndüsengefärbt sind und unterschiedliche Farbe aufweisen. Durch die glatte Ausbildung der Filamentgarne wird eine exzellente Reflexion bei Lichteinfall ermöglicht, die wiederum im Zusammenhang mit den unterschiedlichen Farben der Kettfäden und Schussfäden für eine betrachtungswinkelabhängige Farbe des Gewebes insgesamt sorgt. Dadurch wird ein sogenannter Kippeffekt erreicht: Sind beispielsweise die Kettfäden schwarz und die Schussfäden grün gefärbt, erscheint das Gewebe insgesamt je nach Betrachtungswinkel flächig einmal schwarz und einmal grün. Da zugleich auch vorgesehen ist, dass sowohl die Kettfäden als auch die Schussfäden spinndüsengefärbt sind, also eine Färbung bereits in flüssiger Lösung bzw. Mischung erfolgt, ist auch eine homogene Verteilung und Verankerung der Farbstoffe in den einzelnen Garnen gegeben, sodass das Gewebe und letztlich das textile Flächengebilde insbesondere Witterungseinflüssen gut standhalten kann und eine Langlebigkeit des Produktes gegeben ist. Dies ist insbesondere auf eine feste Verankerung von Farbstoffen innerhalb der Garne zurückzuführen, sodass UV-Bestrahlung, Nässe bzw. Regen oder auch Ozoneinwirkung die Farbstoffe in den Garnen nicht beeinträchtigen bzw. die Garne nicht ausbleichen, wodurch der Kippeffekt verloren gehen würde.An advantage achieved by the invention is the fact that an optically graceful, long-term stable textile fabric is provided even under adverse weather conditions. It is important that the textile fabric is at least partially formed from smooth filament yarns and that both the warp threads and the weft threads are spinneret-dyed and have different colors. The smooth formation of the filament yarns enables excellent reflection in the event of incidence of light, which in turn, in conjunction with the different colors of the warp threads and weft threads, ensures a viewing-color-dependent color of the fabric as a whole. As a result, a so-called tilt effect is achieved: If, for example, the warp threads are black and the weft threads are dyed green, the fabric appears overall, depending on the viewing angle, once black and once green. Since at the same time it is also provided that both the warp threads and the weft threads are spinneret dyed, ie a dyeing already takes place in liquid solution or mixture, there is also a homogeneous distribution and anchoring of the dyestuffs in the individual yarns, so that the fabric and ultimately the yarn textile fabrics in particular Weathering can withstand good and longevity of the product is given. This is due in particular to a firm anchoring of dyes within the yarns, so that UV irradiation, wetness or rain or ozone does not affect the dyes in the yarns or bleach the yarns, whereby the tilting effect would be lost.

Der gewünschte Kippeffekt sowie eine hervorragende Witterungsbeständigkeit und UV-Resistenz ist auch dann gegeben, wenn bloß ein Teil des Gewebes aus Filamentgarn besteht, der übrige Teil jedoch aus einem Stapelfasergarn.The desired tilting effect as well as excellent weathering resistance and UV resistance is also given if only a part of the fabric consists of filament yarn, but the remaining part consists of a staple fiber yarn.

Ein weiterer Vorteil ergibt sich daraus, dass durch die erfindungsgemäße Verwendung von spinndüsengefärbten Kettfäden und Schussfäden das optisch anmutige textile Flächengebilde relativ einfach erstellt werden kann, da nachträgliche Operationen zum Färben einzelner Filamentgarne oder Stapelfasergarne, die im Übrigen auch nicht zweckmäßig wären, entfallen können.Another advantage arises from the fact that the inventive use of spun-dyed warp threads and weft threads the visually graceful fabric can be relatively easily created as subsequent operations for dyeing individual filament yarns or staple fiber yarns, which would otherwise not be useful, can be omitted.

Erfindungsgemäß können die Kettfäden und die Schussfäden jeweils aus einem Polymer bestehen. Dabei kann vorgesehen sein, dass die Kettfäden und die Schussfäden aus unterschiedlichen Polymeren bestehen, beispielsweise Polyester, Polypropylen oder anderen Polymeren. Bevorzugt kann es jedoch je nach Anwendungsfall auch sein, dass die Kettfäden und die Schussfäden aus dem gleichen Polymer bestehen, insbesondere PAN. Dadurch kann im Zusammenhang mit der vorgesehenen Spinndüsenfärbung eine Langlebigkeit bzw. Witterungsstabilität der Garne sichergestellt werden.According to the invention, the warp threads and the weft threads can each consist of a polymer. It can be provided that the warp threads and the weft threads consist of different polymers, for example polyester, polypropylene or other polymers. However, depending on the application, it may also be preferable that the warp threads and the weft threads consist of the same polymer, in particular PAN. As a result, longevity or weathering stability of the yarns can be ensured in connection with the intended spinneret dyeing.

Wichtig ist, dass die Filamentgarne, welche das Gewebe alleine oder zusammen mit Stapelfasergarn bilden, glatt ausgebildet sind. Dabei können sowohl Einzelfilamente als auch Multifilamente vorgesehen sein. Multifilamente weisen den Vorteil auf, dass diese hinsichtlich eines Glanzes bzw. einer Reflexion besonders gut geeignet sind und somit eine erfindungsgemäß gewünschte betrachtungswinkelabhängige flächig gleichmäßige Farbe des textilen Flächengebildes besonders leicht erreicht werden kann. Die Multifilamente können dabei jeweils aus etwa 150 bis 250, vorzugsweise 180 bis 220, Einzelfilamenten gebildet sein. Dies ist insbesondere im Hinblick auf eine Langlebigkeit des textilen Flächengebildes, auch bei extremen Witterungseinflüssen, bevorzugt.Importantly, the filament yarns which form the fabric alone or together with staple fiber yarn are smooth. Both single filaments and multifilaments can be provided. Multifilaments have the advantage that they are particularly well suited for a gloss or a reflection, and thus a viewing angle-dependent surface-uniform color of the textile fabric which is desired according to the invention can be achieved particularly easily. The multifilaments can be formed in each case from about 150 to 250, preferably 180 to 220, individual filaments. This is particularly preferred in view of a longevity of the textile fabric, even in extreme weather conditions.

Ein Verhältnis einer Kettdichte zu einer Schussdichte ist grundsätzlich nicht kritisch, beträgt jedoch bevorzugt 1,5 bis 2,5, um den angestrebten Kippeffekt bzw. einen betrachtungswinkelabhängigen Farbeffekt möglichst zu begünstigen.A ratio of a warp density to a weft density is basically not critical, but is preferably 1.5 to 2.5 in order to favor the desired tilting effect or a viewing angle-dependent color effect as much as possible.

Das textile Flächengebilde kann bei alleiniger Verwendung von Filamentgarnen derart ausgebildet sein, dass eine Feinheit der Kettfäden und der Schussfäden 50 bis 2000 dtex, insbesondere 300 bis 800 dtex, beträgt. Bei einer Feinheit von weniger als 50 dtex sind einzelne Filamente zu dünn und eine Verarbeitung schwierig. Bei einer Feinheit von mehr als 2000 dtex sind die einzelnen Filamentgarne zu dick und wird eine Verarbeitung schwierig. Im Bereich von 300 bis 800 dtex ist neben einer guten Verarbeitbarkeit auch eine Preiswertigkeit der Filamente gegeben.The textile fabric may be formed with the sole use of filament yarns such that a fineness of the warp threads and the weft threads is 50 to 2000 dtex, in particular 300 to 800 dtex. With a fineness of less than 50 dtex, individual filaments are too thin and difficult to process. With a fineness of more than 2000 dtex, the individual filament yarns are too thick and difficult to process. In the range of 300 to 800 dtex in addition to a good processability and a low-cost of the filaments is given.

Wenn nur Filamentgarne eingesetzt werden, können die Kettfäden und die Schussfäden grundsätzlich gleiche Feinheit aufweisen, wiewohl es für die Erzielung verschiedener Farbeffekte bei unterschiedlichen Betrachtungswinkeln von Vorteil sein kann, wenn diese unterschiedliche Feinheit aufweisen.If only filament yarns are used, the warp yarns and the weft yarns may in principle have the same fineness, although it may be advantageous for obtaining different color effects at different viewing angles if they have different fineness.

Die Feinheit der Kettfäden und der Schussfäden kann eine Anmutigkeit bzw. optische Erscheinungsform des textilen Flächengebildes beeinflussen. Bevorzugt ist es diesbezüglich, dass eine Feinheit der Kettfäden zumindest das 1,5-Fache der Schussfäden beträgt.The fineness of the warp threads and the weft threads can influence a gracefulness or visual appearance of the textile fabric. It is preferred in this regard that a fineness of the warp threads is at least 1.5 times the weft threads.

Eine Fadendichte der Kettfäden und/oder Schussfäden liegt grundsätzlich im Bereich von 10 bis 50 Fäden/cm.A thread density of the warp threads and / or weft threads is basically in the range of 10 to 50 threads / cm.

Besonders bevorzugt ist es, dass die Kettfäden und die Schussfäden durch eine Köper-Bindungsart verknüpft sind, die zu einer besonders starken Abhängigkeit der Farbe des textilen Flächengebildes vom Betrachtungswinkel führt. Dies trifft vor allem für Verdecke von Cabriolets zu. Für andere Anwendungszwecke, z. B. Markisen, kann aber auch eine Leinwand-Bindungsart angewendet werden.It is particularly preferred that the warp threads and the weft threads are linked by a twill weave, which leads to a particularly strong dependence of the color of the fabric from the viewing angle. This is especially true for the tops of convertibles. For other applications, eg. As awnings, but can also be applied a canvas-binding style.

Wie bereits erwähnt, können die Kettfäden und die Schussfäden aus einem Filamentgarn einerseits und einem Stapelfasergarn andererseits bestehen. Insbesondere zweckmäßig ist es, die Kettfäden aus einem Stapelfasergarn und die Schussfäden aus einem glatten Filamentgarn bestehen, da sich das textile Flächengebilde dann besonders einfach herstellen lässt. Bei einer solchen Ausbildung kann auch eine optimale Abstimmung von optischem Kippeffekt auf der einen Seite und Witterungsbeständigkeit auf der anderen Seite erfolgen. Die Kettfäden können aus PAN bestehen und z. B. eine schwarze Farbe aufweisen. In dieser Ausbildung sind die Kettfäden insbesondere resistent gegen UV-Einwirkung und vergilben selbst im Test mit einer Xenon-Lampe bei wiederholter Bestrahlung in mehreren Zyklen über insgesamt 350 Stunden nicht. Die als Filamentgarn vorliegenden Schussfäden können in diesem Fall z. B. aus einem Polyester bestehen und weisen eine andere Farbe auf. Durch die entsprechende Kombination bzw. Zusammensetzung und Ausbildung von Kettfäden und Schussfäden ist gleichzeitig auch der gewünschte optische Kippeffekt gegeben.As already mentioned, the warp threads and the weft threads may consist of a filament yarn on the one hand and a staple fiber yarn on the other hand. In particular, it is useful to the warp threads of a staple fiber yarn and the weft threads from a smooth Filament yarn exist because the fabric can then be produced particularly easily. With such a design can also be an optimal vote of optical tilt effect on the one hand and weather resistance on the other hand. The warp threads can consist of PAN and z. B. have a black color. In this embodiment, the warp threads are particularly resistant to UV exposure and do not yellow even in the test with a xenon lamp with repeated irradiation in several cycles over a total of 350 hours. The present as filament yarn wefts can in this case, for. B. consist of a polyester and have a different color. By the appropriate combination or composition and training of warp threads and weft threads is also given the desired optical tilt effect at the same time.

Wenn Anforderungen an eine Licht- und Wetterbeständigkeit weniger hoch sind, können sowohl die Kettfäden als auch die Schussfäden aus PAN bestehen.When light and weather resistance requirements are less stringent, both the warp and weft yarns can be PAN.

Möglich ist es grundsätzlich auch, dass in umgekehrter Weise die Kettfäden aus einem glatten Filamentgarn und die Schussfäden aus einem Stapelfasergarn bestehen.In principle, it is also possible for the warp threads to consist of a smooth filament yarn and the weft threads to consist of a staple fiber yarn in the reverse direction.

Das textile Flächengebilde kann an sich aus dem Gewebe als solchen gebildet sein. Für viele Anwendungszwecke ist es jedoch vorteilhaft, dass das textile Flächengebilde mit einem Untergewebe ausgebildet ist, mit dem das Gewebe verbunden ist. Insbesondere kann vorgesehen sein, dass das Gewebe mit dem Untergewebe über eine Gummischicht verbunden ist. Dadurch wird dem Gewebe, das nach außen hin optisch in Erscheinung tritt, eine für viele Anwendungszwecke erforderliche Stabilität verliehen, beispielsweise Verdecke von Cabriolets oder Markisen oder anderen Einrichtungen, die mit einem Antrieb zum Verfahren einer äußeren Einflüssen wie Witterung oder UV-Bestrahlung ausgesetzten Stoffbahn ausgestattet sind.The textile fabric may be formed as such from the fabric itself. For many applications, however, it is advantageous that the textile fabric is formed with a lower fabric to which the fabric is connected. In particular, it can be provided that the tissue is connected to the lower tissue via a rubber layer. As a result, the fabric, which visually emerges outwardly, imparted stability required for many applications, such as hoods of cabriolets or awnings or other equipment equipped with a drive for the action of external influences such as weathering or UV irradiation exposed fabric are.

Entsprechend den vorstehend dargestellten Vorteilen wird die weitere Aufgabe durch Verwendung eines erfindungsgemäßen Flächengebildes für ein- und ausfahrbare Stoffbahnen, die eine von einem Betrachtungswinkel abhängige variierende Farbe aufweisen, insbesondere Verdecke von Cabriolets oder Markisen, gelöst. Dabei ist insbesondere von Vorteil, dass sich die Farbe der Stoffbahn beim Verfahren je nach Betrachtungswinkel ändert, was einen unerwarteten Effekt ergibt.According to the above-described advantages, the further object is achieved by using a sheet according to the invention for retractable and extendable fabric panels, which have a dependent on a viewing angle varying color, in particular tops of convertibles or awnings. It is particularly advantageous that the color of the fabric changes in the process depending on the viewing angle, resulting in an unexpected effect.

Die noch weitere Aufgabe der Erfindung wird durch eine Vorrichtung der eingangs genannten Art mit einem erfindungsgemäßen textilen Flächengebilde gelöst.The still further object of the invention is achieved by a device of the type mentioned above with a textile fabric according to the invention.

Weitere Merkmale, Vorteile und Wirkungen der Erfindung ergeben sich aus den nachfolgend dargestellten Ausführungsbeispielen.Further features, advantages and effects of the invention will become apparent from the embodiments illustrated below.
