- the invention relates to a method for producing a carrier fabric formed from interwoven warp and weft threads. Furthermore, the invention also relates to such a carrier fabric formed from interwoven warp and weft threads and uses thereof.
- the known threads are due to the twisted orientation of the plastic monofilaments and their inherent high elasticity not suitable to use as warp and weft threads for carrier fabric of the type mentioned use, since the inherent rigidity is not satisfactory.
- the object of the invention is therefore to propose a method for producing a carrier fabric formed from interwoven warp and weft threads, in which the carrier fabric has a particularly high inherent rigidity and is particularly suitable for the production of bellows, inflatable boats and conveyor belts, due to the high inherent rigidity to dispense with a multi-layer sandwich construction with multiple layers of the carrier fabric and a correspondingly high number of elastomer layers, if possible.
- the proposal according to the invention is based on producing the carrier fabric by twisting in each case a plurality of plastic monofilaments in a first step about its longitudinal axis in a first direction of rotation with a predeterminable number of revolutions and in a second subsequent step together with at least one filament yarn be twisted in the opposite direction of rotation with the given number of revolutions in the first direction of rotation.

- the plastic monofilaments are first twisted in a first direction of rotation with the predetermined number of revolutions and then together with the filament yarn in a first direction of rotation opposite direction of rotation are twisted with the same number of turns, are the plastic monofilaments in the connection the twisting with the filament yarn back into untwisted, ie rectilinear alignment along its longitudinal axis, since the first step in a first rotation caused twisting with the specified number of turns in the first step by the subsequent twisting in the opposite direction and with the same number of turns completely turned back.
- the filament yarn twisted with the turned-back plastic monofilaments wound in the longitudinal direction of the monofilaments around their outer surface in the second direction with the specified number of revolutions so that ultimately the plastic monofilaments in straight alignment as the core in untwisted state and completely wrapped with the twisted filament yarn are so that they are no longer visible on the surface of the thus obtained warp or weft thread and the carrier fabric can be produced therefrom.
- the carrier fabric produced in this way is to be used for bellows, inflatable boats or conveyor belts, due to the high inherent stiffness of the carrier fabric, it is only necessary to provide it with at least one, preferably two, surfaces each with a coating layer of elastomer material, so that overall the costs are significantly reduced become.
- a plurality of plastic monofilaments are twisted together in a first step to form each individual warp and weft thread, and then twisted with a filament yarn, or the plastic monofilaments are twisted together with a plurality of filament yarns.
- the number of plastic monofilaments and the filament yarns per warp and / or weft is selected in each case coincident.

Under the unit tours / m is understood in the context of the invention, a number of revolutions per meter running in the longitudinal extension of the plastic monofilaments.
- polyester as a starting material for the plastic monofilaments and / or filament yarns is particularly suitable for general applications, while the use of polyamide may be useful especially for carrier fabric, which are highly loaded, for example in the corner of a bellows, since the bellows here a high tensile load is exposed.
- the from the FIG. 1 apparent thread consists of a core forming plastic monofilament 1, which is made for example of a polyester and extending in untwisted rectilinear alignment along its longitudinal extent L.

Abstract
Description
Die Erfindung betrifft ein Verfahren zur Herstellung eines aus miteinander verwobenen Kett- und Schussfäden gebildeten Trägergewebes. Ferner betrifft die Erfindung auch ein derartiges aus miteinander verwobenen Kett- und Schussfäden gebildetes Trägergewebe sowie Verwendungen desselben.The invention relates to a method for producing a carrier fabric formed from interwoven warp and weft threads. Furthermore, the invention also relates to such a carrier fabric formed from interwoven warp and weft threads and uses thereof.
Es ist bekannt, zur Herstellung von Faltenbälgen für z.B. Gelenkomnibusse sowie zur Herstellung von Schlauchbooten und Fördergurten eines Gurtförderers Trägergewebe auf Basis von Kunststoffmultifilen einzusetzen, bei denen die Kunststoffmultifile als Kett- und Schussfäden miteinander verwoben werden. Nachfolgend wird dieses Trägergewebe auf mindestens einer, vorzugsweise beiden Seiten mit einer Elastomermasse beschichtet, beispielsweise im Streichverfahren mit einer Gummierung versehen. Bei Faltenbälgen für Gelenkbusse oder hochwertigen Schlauchbootstoffen ist es sogar üblich, ein Sandwichmaterial, bestehend aus zwei oder drei derartigen Trägergeweben, die über eine Gummierung miteinander verbunden sind und an ihren Außenoberflächen nochmals mit einer Gummierung versehen sind, d.h. einem Fünf- bzw. Siebenschichtverbund aus zwei bzw. drei Trägergeweben und drei bzw. vier Gummierungsschichten zu verwenden. Dieser Sandwichaufbau erfolgt insbesondere unter dem Gesichtpunkt, dass der Faltenbalg oder der Schlauchbootstoff eine gewisse Eigensteifigkeit aufweisen muss. Nachteilig bei diesem an sich bewährten Aufbau sind jedoch die hohen Kosten, die insbesondere durch die drei- bis vierschichtige Auftragung der Gummierung im Streichverfahren bedingt ist. Aus der

Die bekannten Fäden sind aufgrund der verzwirnten Ausrichtung der Kunststoffmonofile sowie der ihnen innewohnenden hohen Elastizität nicht geeignet, als Kett- und Schussfäden für Trägergewebe der eingangs genannten Art Verwendung zu finden, da die Eigensteifigkeit nicht zufriedenstellend ist.The known threads are due to the twisted orientation of the plastic monofilaments and their inherent high elasticity not suitable to use as warp and weft threads for carrier fabric of the type mentioned use, since the inherent rigidity is not satisfactory.
Aufgabe der Erfindung ist es daher, ein Verfahren zur Herstellung eines aus miteinander verwobenen Kett- und Schussfäden gebildeten Trägergewebes vorzuschlagen, bei dem das Trägergewebe eine besonders hohe Eigensteifigkeit aufweist und insbesondere zur Herstellung von Faltenbälgen, Schlauchbooten und Fördergurten geeignet ist, wobei aufgrund der hohen Eigensteifigkeit auf einen mehrlagigen Sandwichaufbau mit mehreren Schichten des Trägergewebes und entsprechend hoher Anzahl an Elastomerschichten nach Möglichkeit verzichtet werden soll.The object of the invention is therefore to propose a method for producing a carrier fabric formed from interwoven warp and weft threads, in which the carrier fabric has a particularly high inherent rigidity and is particularly suitable for the production of bellows, inflatable boats and conveyor belts, due to the high inherent rigidity to dispense with a multi-layer sandwich construction with multiple layers of the carrier fabric and a correspondingly high number of elastomer layers, if possible.
Diese Aufgabe wird erfindungsgemäß durch ein Verfahren sowie ein Trägergewebe gemäß den Merkmalen der unabhängigen Ansprüche 1 bzw. 8 gelöst.This object is achieved by a method and a carrier fabric according to the features of the independent claims 1 and 8, respectively.
Vorteilhafte Ausgestaltungen und Weiterbildungen der Erfindung sind Gegenstand der abhängigen Ansprüche.Advantageous embodiments and modifications of the invention are the subject of the dependent claims.
Der erfindungsgemäße Vorschlag beruht darauf, das Trägergewebe dadurch herzustellen, dass zur Ausbildung der Kett- und Schussfäden jeweils mehrere Kunststoffmonofile in einem ersten Schritt um ihre Längsachse in einer ersten Drehrichtung mit einer vorgebbaren Tourenzahl verdrillt werden und in einem zweiten anschließenden Schritt gemeinsam mit mindestens einem Filamentgarn in einer der ersten Drehrichtung entgegengesetzten Drehrichtung mit der vorgegebenen Tourenzahl verzwirnt werden. Die solchermaßen erhaltenen Kett- und Schussfäden, jeweils bestehend aus mehreren mit einem Filamentgarn verzwirnten Kunststoffmonofilen können sodann zu dem Trägergewebe verwoben werden.The proposal according to the invention is based on producing the carrier fabric by twisting in each case a plurality of plastic monofilaments in a first step about its longitudinal axis in a first direction of rotation with a predeterminable number of revolutions and in a second subsequent step together with at least one filament yarn be twisted in the opposite direction of rotation with the given number of revolutions in the first direction of rotation. The warp and weft threads thus obtained, each consisting of several plastic monofilaments twisted with a filament yarn, can then be woven into the carrier fabric.
Aufgrund der Tatsache, dass im ersten Schritt des erfindungsgemäßen Verfahrens die Kunststoffmonofile zunächst in einer ersten Drehrichtung mit der vorgegebenen Tourenzahl verdrillt werden und anschließend gemeinsam mit dem Filamentgarn in einer der ersten Drehrichtung entgegengesetzten Drehrichtung mit der gleichen Tourenzahl verzwirnt werden, liegen die Kunststoffmonofile im Anschluss an das Verzwirnen mit dem Filamentgarn wieder in unverdrillter, d.h. geradliniger Ausrichtung entlang ihrer Längsachse vor, da die im ersten Schritt in einer ersten Drehrichtung bewirkte Verdrillung mit der vorgegebenen Tourenzahl durch das anschließende Verzwirnen in der entgegengesetzten Drehrichtung und mit der gleichen Tourenzahl vollständig zurückgedreht wird. Dabei wickelt sich jedoch das mit den zurückgedrehten Kunststoffmonofilen verzwirnte Filamentgarn in Längserstreckung der Monofile um deren Außenoberfläche in der zweiten Drehrichtung mit der vorgegebenen Tourenzahl herum, so dass sich letztlich die Kunststoffmonofile in geradliniger Ausrichtung als Kern in unverdrilltem Zustand wiederfinden und vollständig mit dem verzwirnten Filamentgarn umwickelt sind, so dass sie an der Oberfläche des so erhaltenen Kett- bzw. Schussfadens und des daraus herstellbaren Trägergewebes nicht mehr sichtbar sind.Due to the fact that in the first step of the method according to the invention, the plastic monofilaments are first twisted in a first direction of rotation with the predetermined number of revolutions and then together with the filament yarn in a first direction of rotation opposite direction of rotation are twisted with the same number of turns, are the plastic monofilaments in the connection the twisting with the filament yarn back into untwisted, ie rectilinear alignment along its longitudinal axis, since the first step in a first rotation caused twisting with the specified number of turns in the first step by the subsequent twisting in the opposite direction and with the same number of turns completely turned back. In this case, however, the filament yarn twisted with the turned-back plastic monofilaments wound in the longitudinal direction of the monofilaments around their outer surface in the second direction with the specified number of revolutions, so that ultimately the plastic monofilaments in straight alignment as the core in untwisted state and completely wrapped with the twisted filament yarn are so that they are no longer visible on the surface of the thus obtained warp or weft thread and the carrier fabric can be produced therefrom.
Nach dem Verweben der solchermaßen hergestellten Kett- und Schussfäden in einer an sich bekannten Webart, der keine besondere Limitierung auferlegt ist, erhält man ein äußerst hartes und steifes Gewebe, welches eine gegenüber dem Stand der Technik höhere Festigkeit und Eigensteifigkeit aufweist und sich durch höhere Weiterreißfestigkeit und Schnittfestigkeit auszeichnet.After interweaving the warp and weft threads thus produced in a per se known weaving, which is not particularly limited imposed, one obtains an extremely hard and stiff fabric, which is opposite the prior art higher strength and inherent rigidity and is characterized by higher tear strength and cut resistance.
Diese Eigenschaften sind bei Verwendung des erfindungsgemäßen Trägergewebes in einem Faltenbalg z.B. im Hinblick auf die Widerstandsfähigkeit gegenüber Vandalismus vorteilhaft, bei Verwendung in einem Schlauchboot steigern Sie die Festigkeit gegenüber Grundberührung etc.These properties are when using the carrier fabric according to the invention in a bellows, e.g. advantageous in terms of resistance to vandalism, when used in a dinghy you increase the resistance to ground contact etc.
Sofern das solchermaßen hergestellte Trägergewebe für Faltenbälge, Schlauchboote oder Fördergurte Verwendung finden soll, ist es aufgrund der hohen Eigensteifigkeit des Trägergewebes lediglich erforderlich, dieses an mindestens einer, vorzugsweise beiden Oberflächen mit jeweils einer Beschichtungslage aus Elastomermaterial zu versehen, so dass insgesamt die Kosten bedeutend reduziert werden.If the carrier fabric produced in this way is to be used for bellows, inflatable boats or conveyor belts, due to the high inherent stiffness of the carrier fabric, it is only necessary to provide it with at least one, preferably two, surfaces each with a coating layer of elastomer material, so that overall the costs are significantly reduced become.
Nach der Erfindung werden zur Ausbildung jedes einzelnen Kett- und Schussfadens mehrere Kunststoffmonofile gemeinsam in einem ersten Schritt verdrillt und anschließend mit einem Filamentgarn verzwirnt oder die Kunststoffmonofile werden mit mehreren Filamentgarnen gemeinsam verzwirnt.According to the invention, a plurality of plastic monofilaments are twisted together in a first step to form each individual warp and weft thread, and then twisted with a filament yarn, or the plastic monofilaments are twisted together with a plurality of filament yarns.
Nach einem weiteren Vorschlag der Erfindung ist die Anzahl der Kunststoffmonofile und der Filamentgarne pro Kett- und/oder Schussfaden jeweils übereinstimmend ausgewählt.According to a further proposal of the invention, the number of plastic monofilaments and the filament yarns per warp and / or weft is selected in each case coincident.
Sinnvoll werden im Rahmen der Erfindung Anzahlen von zwei bis vier, vorzugsweise zwei Monofilen und einer entsprechenden Anzahl an Filamentgarnen pro Kett- und Schussfaden angesehen.In the context of the invention, numbers of two to four, preferably two monofilaments and a corresponding number of filament yarns per warp and weft thread are expediently considered.
Die im Rahmen der Erfindung verwendeten Kunststoffmonofile weisen nach einem Vorschlag der Erfindung einen Durchmesser von 0,18 bis 0,40 mm, vorzugsweise 0,25 mm auf, während die Filamentgarne mit einer Fadenstärke von 460 bis 3.300 dtex eingesetzt werden.The plastic monofilaments used in the invention have according to a proposal of the invention a diameter of 0.18 to 0.40 mm, preferably 0.25 mm, while the filament yarns are used with a thread thickness of 460 to 3300 dtex.
Die Kunststoffmonofile und/oder Filamentgarne sind nach einem Vorschlag der Erfindung aus einem Polyester oder Polyamid hergestellt, wobei bevorzugt eine sortenreine übereinstimmende Materialauswahl für die Kunststoffmonofile und die Filamentgarne getroffen wird.The plastic monofilaments and / or filament yarns are made according to a proposal of the invention of a polyester or polyamide, wherein preferably a sorted matching material selection for the plastic monofilaments and the filament yarns is made.
Sofern die Filamentgarne aus einem Polyester hergestellt werden, sind diese nach einem weiteren Vorschlag der Erfindung in einer Fadenstärke von 550 bis 3.300 dtex, vorzugsweise 1.100 dtex ausgeführt. Sofern die Filamentgarne aus einem Polyamid hergestellt sind, beträgt die Fadenstärke etwa 460 bis 2.820 dtex, vorzugsweise 940 dtex.If the filament yarns are made of a polyester, these are according to another proposal of the invention in a thread thickness of 550 to 3300 dtex, preferably 1100 dtex executed. If the filament yarns are made of a polyamide, the thread thickness is about 460 to 2,820 dtex, preferably 940 dtex.
Im Sinne der Erfindung können nicht nur Kunststoffmonofile und/oder Filamentgarne aus einem reinen Polyester, sondern auch aus modifizierten Polyestern zur Anwendung kommen.For the purposes of the invention not only plastic monofilaments and / or filament yarns of a pure polyester, but also of modified polyesters can be used.
Die Tourenzahl, mit der die Kunststoffmonofile in der ersten Drehrichtung verdrillt und anschließend gemeinsam mit den Filamentgarnen in der zweiten entgegengesetzten Drehrichtung verzwirnt werden, liegt nach einem Vorschlag der Erfindung zwischen 50 und 500 Touren/m, vorzugsweise bei etwa 200 Touren/m. Unter der Einheit Touren/m wird im Sinne der Erfindung wird eine Anzahl Umdrehungen pro laufendem Meter in Längserstreckung der Kunststoffmonofile verstanden.The number of revolutions with which the plastic monofilaments are twisted in the first direction of rotation and then twisted together with the filament yarns in the second opposite direction of rotation, according to a proposal of the invention between 50 and 500 tours / m, preferably at about 200 tours / m. Under the unit tours / m is understood in the context of the invention, a number of revolutions per meter running in the longitudinal extension of the plastic monofilaments.
Die Verwendung von Polyester als Ausgangsmaterial für die Kunststoffmonofile und/oder Filamentgarne bietet sich insbesondere für allgemeine Anwendungen an, während die Verwendung von Polyamid insbesondere für Trägergewebe sinnvoll sein kann, die hochbelastet sind, beispielsweise im Eckbereich eines Faltenbalges, da der Faltenbalg hier einer hohen Zugbelastung ausgesetzt ist.The use of polyester as a starting material for the plastic monofilaments and / or filament yarns is particularly suitable for general applications, while the use of polyamide may be useful especially for carrier fabric, which are highly loaded, for example in the corner of a bellows, since the bellows here a high tensile load is exposed.

Der Fachmann wird erkennen, dass diese Verfahrensweise auch mit abweichenden Anzahlen von Kunststoffmonofilen, beispielsweise auch drei, vier oder mehr derartigen Kunststoffmonofilen und entsprechender Anzahl von Filamentgarnen bewirkt werden kann und es auch möglich ist, die Anzahl der verwendeten Kunststoffmonofile und Filamentgarne auch abweichend voneinander auszuwählen.The person skilled in the art will recognize that this procedure can also be effected with deviating numbers of plastic monofilaments, for example also three, four or more such plastic monofilaments and corresponding number of filament yarns and it is also possible to select the number of plastic monofilaments and filament yarns used differently from one another.
In jedem Falle erhält man auf diese Weise als Kett- und Schussfäden für ein Trägergewebe geeignete Fäden, bei denen die Kunststoffmonofile im Kern mit 0 Touren/m sich wiederfinden und an den Oberflächen des Trägergewebes nicht mehr sichtbar sind.In any case, obtained in this way as warp and weft threads for a carrier fabric suitable threads in which the plastic monofilaments in the core with 0 tours / m find themselves and are no longer visible on the surfaces of the carrier fabric.
Für einen z.B. bei Gelenkomnibussen verwendbaren Faltenbalg wurden Kett- und Schussfäden hergestellt, indem jeweils zwei parallele Monofile aus Polyethylenterephthalat (PET) mit einem Durchmesser von jeweils 0,25 mm mit 200 Touren/m in einer ersten Drehrichtung gemeinsam verdrillt und anschließend gemeinsam mit je zwei PET-Filamentgarnen von jeweils 1.100 dtex in entgegengesetzter Drehrichtung mit ebenfalls 200 Touren/m verzwirnt wurden.For a e.g. Warp and weft yarns used in articulated buses were manufactured by twisting two parallel polyethylene terephthalate (PET) monofilaments each 0.25 mm in diameter at 200 turns / m in a first direction of rotation and then together with each two PET filament yarns each of 1,100 dtex in the opposite direction of rotation were also twisted with 200 tours / m.
Aus den solchermaßen erhaltenen Kett- und Schussfäden wurde in einer Leinwand L1/1-Webung ein Trägergewebe mit 6,5/6,5 Fäden/cm in Kett- und Schussrichtung gewebt, welches ein Flächengewicht von 500 g/m2 aufwies.From the warp and weft yarns obtained in this way, a support fabric with 6.5 / 6.5 threads / cm in warp and weft direction was woven in a canvas L1 / 1 weave, which had a basis weight of 500 g / m 2 .
Die Festigkeit des so erhaltenen Trägergewebes betrug in Kettrichtung 5.250 N/5 cm bei einer Bruchdehnung von 27% und in Schussrichtung 5.300 N/5 cm bei einer Bruchdehnung von 23%.The strength of the carrier fabric thus obtained was 5,250 N / 5 cm in the warp direction at an elongation at break of 27% and in weft 5,300 N / 5 cm at an elongation at break of 23%.
Durch nachfolgende Beschichtung der Ober- und Unterseite des Trägergewebes mit einer geeigneten Gummierung wurde ein Faltenbalg mit hervorragenden Eigenschaften erhalten.Subsequent coating of the top and bottom of the base fabric with a suitable gum resulted in a bellows having excellent properties.
