Description

Technisches GebietTechnical area

Die Erfindung betrifft eine Gewebekombination, die insbesondere zur Herstellung von Kleidung geeignet ist, die einen verbesserten Schutz gegen Störlichtbögen bietet.The invention relates to a fabric combination which is particularly suitable for the manufacture of clothing which offers improved protection against arcing faults.

Aus der EP 1 373 617 A2 ( WO 02/079555 A2 ) ist ein verstärktes Gewebe , das aus zwei Garnen derart gewebt ist, dass ein erstes Garn flammhemmend ist und überwiegend die Außenseite des Gewebe bildet und ein zweites Garn mit einer geringen Feinheit, die Innenseite des Gewebes bildet, beispielsweise für die Herstellung von Bekleidungsstücken von Feuerwehrleuten bekannt, das dem Schutz gegen einen Lichtbogen im Fall einer explosionsgefährdeten Umgebung dient. Dies wird durch eine mechanische Verstärkung erreicht. Auf einem ähnlichen Grundgedanken beruht die EP 1 796 492 B1 , gemäß der zwei Lagen eines Gewebes in besonderer Weise und mit Bildung von Lufttaschen verbunden sind.From the EP 1 373 617 A2 ( WO 02/079555 A2 ) is a reinforced fabric which is woven from two yarns such that a first yarn is flame retardant and predominantly forms the outside of the fabric and a second yarn with a low fineness forms the inside of the fabric, for example for the manufacture of garments from firefighters known, which serves to protect against an arc in the event of a hazardous environment. This is achieved by a mechanical reinforcement. On a similar basic idea, the EP 1 796 492 B1 according to which two layers of a fabric are connected in a special way and with the formation of air pockets.

Schließlich betrifft die DE 20 2007 014 673 U1 ein mehrschichtiges textiles Flächengebilde zur Verwendung als Stoff für eine Schutzbekleidung gegen Störlichtbögen, dessen Schichten aus Kett- und Schussfäden gewebt sind, die flammhemmend ausgerüstet sind. Die Garnfeinheit kann Nm 70/2 betragen.Finally, the concerns DE 20 2007 014 673 U1 a multi-layered fabric for use as a protective clothing garment against arcing faults, the layers of which are woven from warp and weft yarns flame retardant. The yarn count can be Nm 70/2.

Darstellung der ErfindungPresentation of the invention

Der Erfindung liegt die Aufgabe zugrunde, eine Gewebekombination zu schaffen, die sowohl einen Schutz gegen Störlichtbögen bildet, als auch ein vergleichsweise niedriges Flächengewicht aufweist.The invention has for its object to provide a fabric combination, which forms both a protection against arcs, and has a relatively low basis weight.

Die Lösung dieser Aufgabe erfolgt durch die im Anspruch 1 beschriebene Gewebekombination.The solution of this task is carried out by the tissue combination described in claim 1.

Demzufolge weist diese ein Innen- und ein Außengewebe auf. Die Webkonstruktion des Außengewebes ist hierbei derart gewählt, dass zwei unterschiedliche Garne miteinander verwoben werden, wobei das erste Garn überwiegend die Außenseite bildet, und das zweite Garn überwiegend an der Innenseite vorgesehen ist. Infolgedessen ist nachfolgend auch von einer äußeren bzw. inneren "Lage" die Rede. Als Beispiele einer geeigneten Bindung seien eine Köper- oder eine abgewandelte Köperbindung genannt.As a result, this has an inner and an outer fabric. The weave construction of the outer fabric is in this case selected such that two different yarns are woven together, wherein the first yarn predominantly forms the outer side, and the second yarn is provided predominantly on the inner side. As a result, the following is also an external or internal "situation" the speech. Examples of a suitable bond include a twill weave or a modified twill weave.

Das erste Garn ist flammhemmend und macht 65% oder mehr, bevorzugt 70%, weiter bevorzugt 73% und insbesondere 75% oder mehr des Flächengewichts des Außengewebes aus. Ferner ist dieses erste Garn in einer Feinheit von mindestens Nm 60/2 ausgesponnen. Dies ermöglicht eine hohe Geschlossenheit oder Dichtigkeit der äußeren Lage des Außengewebes. Das zweite Garn weist eine geringere Feinheit auf als das erste Garn und ist dergestalt verwebt, daß es überwiegend die "innere Lage" des Außengewebes bildet. Diese innere Lage ist dabei vergleichsweise offenporig und strukturiert ausgebildet. Durch die offenporige innere Lage wird somit eine "Verzehrlage" geschaffen, die sich bei elektro-thermischer Belastung unter Sauerstoffverzehr zersetzt und dadurch verhindert, dass auch das Innengewebe, ein flammhemmender Futterstoff, geschädigt wird. Die innere Lage des Außengewebes ist bevorzugt mechanisch schwächer als die äußere Lage des Außengewebes und trägt somit maßgeblich zur Bildung der "Verzehrlage" bei. Zu dem Innengewebe sei erwähnt, dass es unter dem Außengewebe als "erstem Schutzwall" als "zweiter Schutzwall" dient und dementsprechend besonders feinfädig und damit zur Ausbildung einer möglichst geschlossenen Oberfläche vorgesehen ist. Bei ersten Versuchen hat sich herausgestellt, dass ein "arc thermal performance value" APTV gemäß IEC EN 61482-1-1 von 25cal/cm2 bei einem vergleichsweise geringen Flächengewicht von 400 g oder weniger pro Quadratmeter erreicht werden kann. Der Grundgedanke der Erfindung besteht somit nicht in der Erhöhung der mechanischen Festigkeit, sondern in der besonderen Ausgestaltung eines doppelseitigen Außengewebes mit dicht geschlossener Außenseite und offener Innenseite als "Verzehrlage". Es sei erwähnt, dass auch das zweite Garn und/oder das Garn des Innengewebes bevorzugt flammhemmende Eigenschaften aufweist, wenngleich diese weniger ausgeprägt sein können als bei dem ersten Garn. Im Übrigen sind das Innen- und das Außengewebe bevorzugt nicht miteinander verbunden. Dies kann jedoch vorgesehen sein. Üblicherweise werden diese jedoch bei der Herstellung eines Kleidungsstücks zweilagig konfektioniert.The first yarn is flame retardant and accounts for 65% or more, preferably 70%, more preferably 73% and most preferably 75% or more of the basis weight of the outer fabric. Furthermore, this first yarn is spun in a fineness of at least Nm 60/2. This allows a high degree of tightness or tightness of the outer layer of the outer fabric. The second yarn has a lower fineness than the first yarn and is interwoven to form predominantly the "inner layer" of the outer fabric. This inner layer is comparatively open-pored and structured. The open-pore inner layer thus creates a "consumption position" which decomposes under the influence of electro-thermal stress while consuming oxygen and thereby prevents the inner fabric, a flame-retardant lining material, from being damaged. The inner layer of the outer fabric is preferably mechanically weaker than the outer layer of the outer fabric and thus contributes significantly to the formation of the "Verzehrlage" at. Regarding the inner fabric, it should be mentioned that it serves as a "second protective barrier" under the outer fabric as the "first protective barrier" and accordingly is provided with particularly fine threads and thus the formation of a surface which is as closed as possible. Initial tests have shown that an arc thermal performance value APTV according to IEC EN 61482-1-1 of 25 cal / cm 2 can be achieved with a comparatively low basis weight of 400 g or less per square meter. The basic idea of the invention is therefore not in the Increasing the mechanical strength, but in the particular embodiment of a double-sided outer fabric with tightly closed outside and open inside as a "consumption position". It should be noted that the second yarn and / or the yarn of the inner fabric also preferably has flame-retardant properties, although these may be less pronounced than in the case of the first yarn. Incidentally, the inner and outer fabrics are preferably not connected to each other. However, this can be provided. Usually, however, these are made up of two layers in the production of a garment.

Bevorzugte Weiterbildungen der erfindungsgemäßen Gewebekombination sind in den weiteren Ansprüchen beschrieben.Preferred developments of the tissue combination according to the invention are described in the further claims.

Für das Flächengewicht des Außengewebes bzw. des Innengewebes haben sich 230 bis 240 und insbesondere 235 g/m2 bzw. 160 bis 170 und insbesondere etwa 165 g/m2 als vorteilhaft erwiesen.230 to 240 and in particular 235 g / m 2 or 160 to 170 and in particular approximately 165 g / m 2 have proved to be advantageous for the basis weight of the outer fabric or inner fabric.

Im Hinblick auf den Anteil des ersten Garns am Flächengewicht des Außengewebes wurden gute Eigenschaften für Anteile von 75 bis 85% und insbesondere etwa 80% festgestellt.With regard to the proportion of the first yarn in the basis weight of the outer fabric, good properties were found for proportions of 75 to 85% and in particular about 80%.

Für das erste Garn wird derzeit bevorzugt, dass es aus mindestens 70% meta-Aramid, etwa 2% Antistatikfasern und im Übrigen aus para-Aramid besteht. Hierdurch wird durch die äußerste Gewebelage ein erster "Schutzwall" gegen Störlichtbögen gebildet.For the first yarn, it is presently preferred to consist of at least 70% meta-aramid, about 2% antistatic fibers, and otherwise para-aramid. As a result, a first "protective wall" is formed against arcs through the outermost fabric layer.

Für das zweite, weniger fein als das erste Garn ausgesponnene Garn wird derzeit eine Feinheit zwischen Nm 34/2 und 45/2 bevorzugt.For the second yarn, less finely spun than the first yarn, a fineness between Nm 34/2 and 45/2 is currently preferred.

Ferner haben sich gute Eigenschaften für ein zweites Garn ergeben, das aus etwa 40 bis 60% flammhemmend modifizierter Acrylfaser, sogenanntem Modacryl, und im Übrigen aus Baumwolle besteht. Hierdurch wird, wie erwähnt, eine offen und grobstrukturierte Oberfläche zum Innengewebe gebildet, die in Kombination mit der dichten und glatten äußersten Lage in vorteilhafter Weise für die beschriebene "Verzehrlage" sorgt. In vorteilhafter Weise weist das zweite Garn durch die Verwendung eines hohen Anteils von Modacryl ebenfalls flammhemmende Eigenschaften auf.Furthermore, good properties have resulted for a second yarn, which consists of about 40 to 60% of flame-retardant modified acrylic fiber, so-called modacrylic, and the rest of Cotton exists. As a result, as mentioned, an open and coarsely textured surface to the inner fabric is formed, which provides in combination with the dense and smooth outermost layer advantageously for the described "consumption position". Advantageously, the second yarn also has flame retardant properties through the use of a high level of modacrylic.

Für das Innengewebe wird derzeit die Verwendung eines Garns sowohl in Kette als auch in Schuss mit einer Feinheit von Nm 40/2 bis 50/2 bevorzugt.For the inner fabric, the use of a yarn in both warp and weft with a fineness of Nm 40/2 to 50/2 is currently preferred.

Gute Eigenschaften im Hinblick auf die ergänzende Flammhemmung wurden ferner festgestellt, wenn das Innengewebe zu 60 bis 40% aus meta-Aramidfasern und zu 40 bis 60% aus flammhemmend modifizierter Viskose oder Modalviskosefaser besteht.Good flame retardancy was also found when the inner fabric is 60-40% meta-aramid fiber and 40-60% flame retardant modified viscose or modal viscose fiber.

Schließlich ergeben sich Vorteile, wenn die erfindungsgemäße Gewebekombination einen APTV gemäß IEC EN 61482-1-1 von 25cal/cm2 oder mehr aufweist. Bei diesem Wert zeigt das Innengewebe bei den genormten Testbedingungen keine Lochbildung oder sonstige Schädigung, während das Außengewebe teilweise völlig zerstört wird und insoweit in vorteilhafter Weise als "Verzehrlage" wirkt.Finally, there are advantages when the tissue combination according to the invention has an APTV according to IEC EN 61482-1-1 of 25cal / cm 2 or more. At this value, the inner fabric shows no puncturing or other damage in the standardized test conditions, while the outer fabric is partially completely destroyed and so far advantageously acts as a "Verzehrlage".
