Description

Die Erfindung betrifft ein Gewebe mit Kettfäden und Schussfäden.The invention relates to a fabric with warp threads and weft threads.

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

Sonnenexponierte Bereiche können zum Schutz von Personen mit fixen oder bedarfsweise ein- und ausfahrbaren Beschattungselementen ausgestattet sein. Ein Beispiel hierfür sind Markisen, wie diese häufig bei Terrassen oder Balkonen von Wohnhäusern vorgesehen sind.Sun-exposed areas can be equipped to protect people with fixed or, if necessary, retractable and extendable shading elements. An example of this are awnings, as they are often provided on terraces or balconies of residential buildings.

Ein Beschattungselement wie eine Markise ist in der Regel aus einem Gewebe aufgebaut, das mit mechanischen Komponenten verbunden ist, die entweder eine fixe oder zeitliche variable Positionierung des Beschattungselementes erlauben. Bei einer Markise ist zum Beispiel in der Regel ein Rahmen vorgesehen, in welchem die Markise aufgerollt eingespannt ist und bei Bedarf unter Abrollen ausgefahren und später wieder eingefahren werden kann.A shading element such as an awning is usually constructed of a fabric which is connected to mechanical components which allow either a fixed or temporally variable positioning of the shading element. In the case of an awning, a frame is generally provided, for example, in which the awning is clamped rolled up and, if necessary, can be extended under unrolling and retracted later.

Das Gewebe einer Markise oder auch eines anderen Beschattungselementes ist neben einer Bestrahlung durch Sonnenlicht insbesondere auch Witterungseinflüssen ausgesetzt. Das Gewebe hält üblicherweise auch einer jahrelangen Sonnenlichteinwirkung stand, da das Gewebe gerade für diesen Zweck ausgerichtet ist. Witterungseinflüsse wie Regen oder Schnee können dem Gewebe allerdings zusetzen und auch zu einem nicht erwünschten Aussehen führen. Insbesondere Regentropfen, die sich beispielsweise auf einer Markise ablagern, können insbesondere bei dunkleren Markisenstoffen zu unerwünschten Farbflecken führen. Dieser unerwünschte Effekt kann sich bei starkem Pollenflug verstärken.The fabric of an awning or of another shading element is in addition exposed to exposure to sunlight, in particular weathering. The fabric usually withstands many years of exposure to sunlight because the fabric is just designed for this purpose. However, weather influences such as rain or snow can clog the fabric and also lead to an undesirable appearance. In particular raindrops, which are deposited, for example, on an awning, can lead to undesirable color spots, especially in the case of darker awning fabrics. This undesirable effect can increase with strong pollen.

Noch wichtiger ist, dass Regenwasser indirekt auch die Langlebigkeit des Gewebes beeinträchtigen kann. Wird eine Markise bei Regen eingefahren, befinden sich bereits Regentropfen auf der Markise und werden mit dieser eingerollt, wenn die Markise nach einsetzendem Regen auf eine hierfür vorgesehene Welle aufgerollt wird. In der Folge verbleibt das Wasser innerhalb der aufgerollten Markise, was im Laufe der Zeit zu Schimmelbildung führen kann, je nachdem, wie lange die Markise im eingerollten Zustand verbleibt. DE 20 2013 002 389 U1 offenbart ein Markisentuch mit mindestens zwei Gewebebahnen mit Kettfäden und Schussfäden, wobei die Kettfäden abwechselnd aus Bereichen mit größerem und kleinerem Fadendurchmesser gebildet sind, sodass in einem Querschnitt des Gewebes Oberflächen der Bereiche des einen Kettfadens höher als Oberflächen der Bereiche des anderen Kettfadens liegen. Diese Anordnung dient zur Vermeidung der Faltenbildung an den Nahtstellen beim Aufrollen des Markisentuchs.More importantly, rainwater can also indirectly affect the longevity of the tissue. If an awning retracts in the rain, raindrops are already on the awning and are rolled up with this, if the awning is rolled up after the onset of rain on a shaft provided for this purpose. As a result, the water remains inside the rolled-up awning, which increases over time Depending on how long the awning remains in the rolled-up state. DE 20 2013 002 389 U1 discloses an awning fabric having at least two webs of warp and weft yarns, wherein the warp yarns are alternately formed of regions of larger and smaller yarn diameters such that in a cross section of the fabric surfaces of the regions of one warp are higher than surfaces of the regions of the other warp. This arrangement serves to avoid the formation of wrinkles at the seams when rolling up the awning fabric.

Die Erfindung stellt sich die Aufgabe, ein Gewebe anzugeben, mit welchem die vorstehend erläuterten Probleme vermeidbar sind.The object of the invention is to provide a fabric with which the above-described problems can be avoided.

Diese Aufgabe wird gelöst, wenn bei einem Gewebe der eingangs genannten Art die Kettfäden abwechselnd aus Bereichen aus Multifilamentgarn und Bereichen aus Stapelfasergarn gebildet sind, wobei das Stapelfasergarn einen größeren Durchmesser als das Multifilamentgarn aufweist, sodass in einem Querschnitt des Gewebes Oberflächen der Bereiche des Stapelfasergarns höher als Oberflächen der Bereiche des Mutlifilamentgarns liegen.This object is achieved if, in a fabric of the type mentioned, the warp threads are formed alternately from areas of multifilament yarn and areas of staple fiber yarn, wherein the staple fiber yarn has a larger diameter than the multifilament yarn, so that in a cross section of the fabric surfaces of the areas of the staple fiber yarn higher as surfaces of the areas of the multifilament yarn.

Ein erfindungsgemäßes Gewebe zeichnet sich dadurch aus, dass durch die bei den Kettfäden getroffene abwechselnde Anordnung von Bereichen aus Multifilamentgarn einerseits und Bereichen aus Stapelfasergarn andererseits quasi eine Kanalstruktur gebildet werden kann, wenn das Stapelfasergarn einen größeren Durchmesser als das Mulitfilamentgarn aufweist. Es liegen dann die Oberflächen der Bereiche aus Stapelfasergarn in einem Querschnitt des Gewebes senkrecht zu den Kettfäden betrachtet über den Oberflächen der Bereiche aus Mulitfilamentgarn. Allfälliges Wasser kann dann entlang der tiefer liegenden Bereiche des Mulitfilamentgarns abgeleitet werden. Dies ist beispielsweise von Nutzen, wenn das Gewebe in einer Markise eingesetzt wird und die Markise aufgerollt wird. Die Kanalstruktur erstreckt sich dann bei entsprechender Anordnung des Gewebes entlang der Richtung des Ein- bzw. Ausfahrens.A fabric according to the invention is characterized in that, as a result of the alternating arrangement of regions of multifilament yarn on the one hand and regions of staple fiber yarn on the other hand, a channel structure can be virtually formed if the staple fiber yarn has a larger diameter than the multi-filament yarn. The surfaces of the staple fiber yarn areas in a cross-section of the fabric perpendicular to the warp yarns are then over the surfaces of the areas of multi-filament yarn. Any water may then be drained along the lower lying areas of the multi-filament yarn. This is useful, for example, when the fabric is used in an awning and the awning is rolled up. The channel structure then extends with appropriate arrangement of the tissue along the direction of extension or extension.

Beim Einfahren der Markise wird das Wasser dann entlang der Bereiche aus Mulitfilamentgarn hinausgedrückt, sodass eine Ansammlung von Wasser im aufgerollten Markisenbereich minimiert oder zumindest verringert ist.When retracting the awning, the water is then pushed out along the areas of Mulitfilamentgarn so that accumulation of water in the rolled up awning area is minimized or at least reduced.

Die Bereiche aus Multifilamentgarn können aus 1 bis 40, vorzugsweise 1 bis 30, besonders bevorzugt 2 bis 20, insbesondere 2 bis 8, unmittelbar nebeneinander angeordnete Multifilamentgarne aufweisen bzw. aus diesen gebildet sein. Grundsätzlich ist bereits ein einzelnes Mutlifilamentgarn ausreichend, um einen entsprechenden Bereich für die Kettfäden auszubilden. Bevorzugt sind jedoch zumindest zwei Multifilamentgarne vorgesehen, die unmittelbar nebeneinander angeordnet sind. Es hat sich als zweckmäßig erwiesen, eine obere Anzahl von unmittelbar nebeneinander angeordneten Multifilamentgarnen mit 40, vorzugsweise 30, zu beschränken. Sind mehr nebeneinander angeordnete Multifilamentgarne vorgesehen, werden die entsprechenden Bereiche so breit, dass ein asymmetrisches Festigkeitsverhältnis entstehen kann. Dies ergibt sich daraus, dass hauptsächlich die Multifilamentgarne für die Festigkeit verantwortlich sind bzw. Kräfte aufnehmen. Als besonders vorteilhaft zur Optimierung aller Gebrauchseigenschaften hat sich diesbezüglich erwiesen, eine obere Anzahl von Multifilamentgarnen auf 8 zu beschränken.The regions of multifilament yarn may comprise from 1 to 40, preferably 1 to 30, more preferably 2 to 20, in particular 2 to 8, directly adjacent to each other arranged multifilament yarns or be formed from these. Basically, a single multifilament yarn is already sufficient to form a corresponding area for the warp threads. Preferably, however, at least two multifilament yarns are provided, which are arranged directly next to each other. It has proven to be appropriate have proven to limit an upper number of immediately adjacent multifilament yarns of 40, preferably 30. If more juxtaposed multifilament yarns are provided, the corresponding areas become so wide that an asymmetrical strength ratio can arise. This results from the fact that mainly the multifilament yarns are responsible for the strength or absorb forces. In this regard, it has proven to be particularly advantageous for optimizing all use properties to limit an upper number of multifilament yarns to 8.

Das Multifilamentgarn kann insbesondere als glattes Garn vorliegen, was einen Abfluss von Wasser fördert.The multifilament yarn may in particular be in the form of a smooth yarn, which promotes a drainage of water.

Da das Multifilamtengarn ebenso wie das Stapelfasergarn neben Witterungseinflüssen insbesondere auch einer UV-Bestrahlung ausgesetzt ist, ist es zweckmäßig, wenn das Multifilamentgarn spinndüsengefärbt ist.Since the multifilament yarn, like the staple fiber yarn, is exposed to weathering influences, in particular also to UV irradiation, it is expedient for the multifilament yarn to be spinneret-dyed.

Das Multifilamentgarn kann aus beliebigen hierfür geeigneten Materialien bestehen, die sich insbesondere auch mittels Spinndüsenfärbung verarbeiten lassen. Hierfür kommen beispielsweise Polyester oder Polypropylen infrage. Besonders bevorzugt ist ein Einsatz von Polyacrylnitril.The multifilament yarn can consist of any materials suitable for this purpose, which can be processed in particular by means of spinneret dyeing. For this example, polyester or polypropylene come into question. Particularly preferred is a use of polyacrylonitrile.

Die Bereiche aus Stapelfasergarn können zum Beispiel aus 1 bis 15, vorzugsweise 1 bis 10, insbesondere 2 bis 8, unmittelbar nebeneinander angeordnete Stapelfasergarne aufweisen bzw. aus diesen gebildet sein. Die Anzahl der Stapelfasergarne eines Bereiches derselben wird insbesondere auf die Bereiche aus Multifilamentgarnen abgestimmt.The regions of staple fiber yarn can, for example, comprise or be formed from 1 to 15, preferably 1 to 10, in particular 2 to 8, staple fiber yarns arranged directly next to one another. The number of staple fiber yarns of a range thereof is particularly tuned to the areas of multifilament yarns.

Auch das Stapelfasergarn kann so wie das Multifilamentgarn bevorzugt spinndüsengefärbt vorliegen.The staple fiber yarn may also be in the form of a spinneret, as is the case with the multifilament yarn.

Die Schussfäden können grundsätzlich aus einem beliebigen Garn bestehen. Bevorzugt bestehen die Schussfäden aus einem Garn aus Multifilament. Insbesondere können die Schussfäden aus dem gleichen Multifilamentgarn gebildet sein, das auch in den Kettfäden vorliegt.The weft threads can basically consist of any yarn. The weft threads preferably consist of a multifilament yarn. In particular, the weft threads may be formed from the same multifilament yarn which is also present in the warp threads.

Entsprechend den vorstehend dargestellten Vorteilen kommt ein erfindungsgemäßes Gewebe insbesondere als Gewebe für Markisen zur Anwendung.In accordance with the advantages presented above, a fabric according to the invention is used, in particular, as tissue for awnings.

Weitere Merkmale, Vorteile und Wirkungen der Erfindung ergeben sich aus dem nachfolgend dargestellten Ausführungsbeispiel. In den Zeichnungen, auf welche dabei Bezug genommen wird, zeigen:

  • Fig. 1 ein schematisch dargestelltes Gewebe;
  • Fig. 2 Bereiche verschiedener Garne im Querschnitt;
  • Fig. 3 eine schematische Darstellung der Oberfläche eines erfindungsgemäßen Gewebes.
Further features, advantages and effects of the invention will become apparent from the embodiment illustrated below. In the drawings, to which reference is made, show:
  • Fig. 1 a schematically illustrated tissue;
  • Fig. 2 Areas of different yarns in cross section;
  • Fig. 3 a schematic representation of the surface of a fabric according to the invention.

In Fig. 1 ist ein erfindungsgemäßes Gewebe 1 stark schematisiert dargestellt. Das Gewebe 1 ist aus Kettfäden 2 und Schussfäden 3 gebildet. Die Kettfäden 2 bestehen zum einen aus einem Mulitfilamentgarn 4 und zum anderen aus einem Stapelfasergarn 5. Das Multifilamentgarn 4 ist in Bündeln von beispielsweise 2 bis 8 Garnen angeordnet, zwischen welchen sich kein Stapelfasergarn 5 befindet. Die so angeordneten Multifilamentgarne 4 bilden damit einen Bereich 41 mit einer oberen, kopfseitigen Oberfläche 42 dieses Bereiches 41 aus. Das Multifilamentgarn 4 kann dabei beispielsweise aus Polyacrylnitril gebildet sein. Zur Bildung des Monofilamentgarns 4 werden bis zu 200 Monofilamente miteinander verbunden. Dabei ist es von Vorteil, wenn spinndüsengefärbte Monofilamente verwendet werden.In Fig. 1 an inventive fabric 1 is shown in a highly schematic. The fabric 1 is formed of warp threads 2 and weft threads 3. The warp threads 2 consist on the one hand of a multi-filament yarn 4 and on the other hand of a staple fiber yarn 5. The multifilament yarn 4 is arranged in bundles of, for example, 2 to 8 yarns, between which there is no staple fiber yarn 5. The multifilament yarns 4 thus arranged thus form a region 41 with an upper, head-side surface 42 of this region 41. The multifilament yarn 4 can be formed, for example, from polyacrylonitrile. To form monofilament yarn 4, up to 200 monofilaments are bonded together. It is advantageous if spinneret-dyed monofilaments are used.

Die Bereiche 41 des Multifilamentgarns 4 sind abwechselnd bzw. alternierend mit Bereichen 51 eines Stapelfasergarns 5 angeordnet. Auch das Stapelfasergarn 5 liegt nicht als einzelnes Garn, sondern als Bündel von nebeneinander angeordneten Stapelfasergarnen 5 vor, welche gemäß Fig. 2 einen Bereich 51 mit dessen Oberseite bzw. Oberfläche 52 ausbilden. Bevorzugt ist es, dass das Stapelfasergarn 5 in der Breite auf eine Breite 41 des Multifilamentgarns 4 abgestimmt ist. Beispielsweise können beide Bereiche jeweils aus vier nebeneinander angeordneten Garnen gebildet sein. Das Stapelfasergarn 5 kann wie das Multifilamentgarn 4 spinndüsengefärbt sein.The regions 41 of the multifilament yarn 4 are arranged alternately or alternately with regions 51 of a staple fiber yarn 5. The staple fiber yarn 5 is not present as a single yarn, but as a bundle of adjacent staple yarns 5, which according to Fig. 2 form a region 51 with its upper side or surface 52. It is preferred that the staple fiber yarn 5 is matched in width to a width 41 of the multifilament yarn 4. For example, both areas may each be formed of four adjacent yarns. The staple fiber yarn 5 may be spinneret-dyed like the multifilament yarn 4.

Das Gewebe 1 weist neben den Kettfäden 2 übliche Schussfäden 3 auf, die in Fig. 1 lediglich strichliert angedeutet sind. Der exakte Verlauf der Schussfäden 3 hängt von der gewählten Bindungsart ab. Die Bindungsart kann beliebig gewählt werden, beispielsweise wohlbekannte Bindungen wie Leinwandbindung, Köperbindung oder Atlasbindung. Die Schussfäden 3 können beispielsweise aus dem gleichen Multifilamentgarn 4 bestehen wie jene der Bereiche 41 der Kettfäden 2.The fabric 1 has in addition to the warp threads 2 usual weft threads 3, which in Fig. 1 only indicated by dashed lines. The exact course of the weft threads 3 depends on the chosen type of binding. The type of binding can be chosen arbitrarily, for example Well-known bindings such as plain weave, twill weave or satin weave. The weft threads 3 may, for example, consist of the same multifilament yarn 4 as those of the regions 41 of the warp threads 2.

Die Multifilamentgarne 4 der Kettfäden 2 sind mit einem Durchmesser ausgebildet, der kleiner als jener der Stapelfasergarne 5 ist. Dadurch ergibt sich, wie in Fig. 2 schematisch dargestellt, im Querschnitt des Gewebes 1 eine Struktur, bei welcher die Bereiche 41 höhenmäßig unter jenen der Bereiche 51 liegen. Die höhenmäßige Differenz bezieht sich hierbei insbesondere auf eine Oberseite bzw. Oberseite 42 des Bereiches 41 der Multifilamentgarne 4 im Vergleich mit der Oberseite bzw. Oberfläche 52 des Bereiches 51 der Stapelfasergarne 5. In Fig. 2 sind zwar die Schussfäden 3 nicht eingezeichnet, unabhängig von der Art der Bindung ändern die Schussfäden 3 allerdings nichts daran, dass im Durchschnitt die Bereiche 41 mit deren Oberfläche 42 unterhalb der Oberfläche 52 der Bereiche 51 liegen. Damit sind an der Oberseite des Gewebes 1 Kanalstrukturen geschaffen, durch welche Wasser abfließen kann. Zusammen mit dem Abfluss von Wasser wird auch Schmutz abtransportiert. Dies wird auch dann begünstigt, wenn die Mulitfilamentgarne 4 glatt ausgebildet sind, womit die Kanalstruktur optimiert ist.The multifilament yarns 4 of the warp yarns 2 are formed with a diameter smaller than that of the staple fiber yarns 5. This results in how in Fig. 2 schematically illustrated, in the cross section of the fabric 1, a structure in which the areas 41 are lower in height than those of the areas 51. The difference in height here refers in particular to an upper side or upper side 42 of the region 41 of the multifilament yarns 4 in comparison with the upper side or surface 52 of the region 51 of the staple fiber yarns 5. In Fig. 2 Although the weft threads 3 are not drawn, regardless of the type of binding, the weft threads 3 do not change the fact that, on average, the areas 41 lie with their surface 42 below the surface 52 of the areas 51. This 1 channel structures are created at the top of the fabric through which water can flow. Together with the drainage of water and dirt is transported away. This is also favored when the Mulitfilamentgarne 4 are smooth, whereby the channel structure is optimized.

Eine entsprechende schematische Darstellung der sich so ergebenen Oberseite des Gewebes 1 ist in Fig. 3 dargestellt, wobei die Kanalstrukturen ersichtlich sind.A corresponding schematic representation of the thus resulting top side of the fabric 1 is shown in FIG Fig. 3 represented, wherein the channel structures are visible.

Ein Gewebe 1 wie vorstehend dargestellt kann in beliebigen Bereichen zum Einsatz kommen, insbesondere im Außenbereich. Dabei hat sich eine Verwendung für Markisen als besonders vorteilhaft erwiesen. Das Gewebe 1 wird auf der Markise so befestigt, dass die Kanalstrukturen entlang einer Einfahr- bzw. Ausfahrrichtung angeordnet sind. Dadurch rinnt Wasser bevorzugt entlang der Kanäle ab und kann insbesondere beim Einfahren der Markise auch quasi ausgepresst werden.A fabric 1 as shown above can be used in any areas, especially in the outdoor area. In this case, a use for awnings has proven to be particularly advantageous. The fabric 1 is mounted on the awning so that the channel structures are arranged along a retraction or extension direction. As a result, water preferably drains along the channels and, in particular, can also be virtually squeezed out when the awning is retracted.
