Description

Die Erfindung bezieht sich auf ein Gewebe für hitze- und flammfeste Schutzkleidung, die insbesondere bei Schweißarbeiten, Arbeiten, bei denen ein Schutz vor Lichtbögen zu gewährleisten ist, Feuerwehreinsätzen, dort als Dienst- und/oder Einsatzbekleidung, und ähnlichen Tätigkeiten eingesetzt wird, aus einem Garn, dessen Gesamtmischung Metaaramid, Viskose FR (Flame Retardant) und Antistatikum enthält. Ein solches Gewebe ist aus der DE 298 05 867 U1 bekannt.The invention relates to a fabric for heat- and flame-resistant protective clothing, which is used in particular in welding, work, in which a protection against electric arcs is to be used, firefighting missions, there as a service and / or protective clothing, and similar activities, from a Yarn whose total mixture contains meta-aramid, viscose FR (flame retardant) and antistatic agent. Such a fabric is from the DE 298 05 867 U1 known.

Bei der Durchführung von Schweißarbeiten und ähnlichen Tätigkeiten sind die damit befassten Personen naturgemäß erheblichen Belastungen ausgesetzt. Die Schutzkleidung für diese Personen muss daher eine große Sicherheit gegen die Einwirkungen hoher Temperaturen (hohe Isolation), Flammen, Metallspritzern und Lichtbögen gewährleisten. Des Weiteren muss bei der Auslegung des Gewebes für diese Schutzkleidung beachtet werden, dass die die Schutzkleidung tragenden Personen sehr beweglich sein müssen, dass die Schutzkleidung eine lange Lebensdauer aufweisen soll und dass die Schutzkleidung seitens der sie tragenden Personen nicht als hinderlich empfunden wird. Selbstverständlich muss diese Schutzkleidung feuerfest und schwer entflammbar sein.When carrying out welding and similar activities, the persons involved are naturally exposed to considerable burdens. The protective clothing for these persons must therefore ensure a high level of protection against the effects of high temperatures (high insulation), flames, metal splashes and electric arcs. Furthermore, when designing the fabric for this protective clothing, it must be taken into account that the persons wearing the protective clothing must be very flexible, that the protective clothing should have a long service life, and that the protective clothing is not perceived as a hindrance by the persons carrying it. Of course, this protective clothing must be fireproof and flame retardant.

Zur Erfüllung dieses Anforderungsprofils ist eine Vielzahl unterschiedlicher Gewebe realisiert worden, z.B. Gewebe aus Wolle, Viskose FR und Polyamid, aus mit einer Flammschutzimprägnierung versehener Baumwolle und dergleichen.To meet this requirement profile, a variety of different fabrics have been realized, e.g. Wool, viscose FR and polyamide fabrics, cotton impregnated with flame retardant impregnation and the like.

Ausgehend von dem eingangs geschilderten Stand der Technik liegt der Erfindung die Aufgabe zugrunde, ein Gewebe für hitze- und flammfeste Schutzkleidung zu schaffen, mittels dem insbesondere der Aufprall von Metallspritzern und Lichtbögen hitzetechnisch noch besser zu beherrschen ist.Based on the above-described prior art, the present invention seeks to provide a fabric for heat- and flame-resistant protective clothing, by means of which in particular the impact of metal spatters and arcs heat control is even better to control.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, dass bei einem derartigen Gewebe für hitze- und flammfeste Schutzkleidung das Gewebe als gleichseitiger Kreuzkörper 2/2 ausgebildet ist. Hierdurch werden die Widerstandsfähigkeit des Gewebes gegen aufprallende Metallspritzer bzw. -tropfen und die Isolation gegen die auftreffende Hitze erhöht.This object is achieved in that in such a fabric for heat- and flame-resistant protective clothing, the fabric is designed as an equilateral equilateral body 2/2. As a result, the resistance of the fabric against impacting metal splashes or drops and the insulation against the impinging heat are increased.

Das Gewebe besteht aus einem Garn, dessen Gesamtmischung Metaaramid, Viskose FR (Flame Retardant) und Antistatikum enthält. Gemäß einer vorteilhaften Weiterbildung der Erfindung kann die Gesamtmischung des Garns darüber hinaus auch Paraaramid bezichungsweise Polyamidimide enthalten.The fabric consists of a yarn whose total mixture contains meta-aramid, viscose FR (flame retardant) and antistatic agent. According to an advantageous development of the invention, the total mixture of the yarn may also contain para-aramid or polyamide-imides.

Wenn das Gewebe auf seiner dem Körper des Schweißers od.dgl. zugewandten Innenseite aufgerauht ist, wird durch die zusätzliche Aufrauhung zum einen der Tragekomfort eines entsprechend gestalteten Kleidungsstücks erhöht; ergänzend ergeben sich erheblich verbesserte Isolationseigenschaften eines betreffenden Kleidungsstücks.If the fabric or the like on his body of the welder. roughened facing inside, is increased by the additional roughening on the one hand the wearing comfort of a suitably shaped garment; In addition, significantly improved insulation properties of a garment in question.

Darüber hinaus wird aufgrund dieser zusätzlichen Aufrauhung an der Innenseite des Gewebes die Möglichkeit eröffnet, die für derartige Schutzbekleidung geltende Euronorm EN 11611 Klasse 2 zu erfüllen, d.h., entsprechend ausgestaltete Kleidungsstücke bieten Schutz für deutlich mehr als 25 auftreffende flüssige Metalltropfen.In addition, this additional roughening on the inside of the fabric opens the possibility of meeting the EN 11611 Class 2 Euronorm standard applicable to such protective clothing, ie suitably designed garments provide protection for significantly more than 25 impinging drops of liquid metal.

Gemäß einer vorteilhaften Ausgestaltung des erfindungsgemäßen Gewebes für hitze- und flammfeste Schutzkleidung enthält die Gesamtmischung des Kett- und des Schussgarns des Gewebes bis zu 18, vorzugsweise 15 Gew.-% Paraaramid, 35 bis 60, vorzugsweise 43,4 Gew.-% Metaaramid, 35 bis 46, vorzugsweise 40,6 Gew.-% Viskose FR und einen geringen Anteil, z.B. etwa 1 Gew.-%, Antistatikum.According to an advantageous embodiment of the fabric according to the invention for heat- and flame-resistant protective clothing contains the total mixture of the warp and the weft yarn of the fabric up to 18, preferably 15 wt .-% paraaramide, 35 to 60, preferably 43.4 wt .-% meta-amide, 35 to 46, preferably 40.6 wt .-% viscose FR and a small proportion, eg about 1 wt .-%, antistatic.

Durch ein entsprechend ausgebildetes Gewebe für hitze- und flammfeste Schutzkleidung lässt sich erreichen, dass Metallspritzer bzw. -tropfen auf einen Flächenabschnitt der Schutzkleidung aufprallen können, die die Norm DIN EN ISO 11611 mindestens fordert, ohne dass die Gefahr von Durchtritten dieser Metallspritzer bzw. -tropfen durch das Schutzgewebe besteht oder die geforderten Hitzedurchgangswerte überschritten werden.By means of a suitably formed fabric for heat- and flame-resistant protective clothing, it is possible to strike metal splashes or drops onto a surface section of the protective clothing which at least requires the standard DIN EN ISO 11611, without the danger of the metal splashes or dripping through the protective fabric or the required heat transfer values are exceeded.

Das Kett- und das Schussgarn des Gewebes ist vorteilhaft aus einem Zweifadenzwirn ausgebildet, der eine Feinheit von 133 tex bis 33 tex, vorzugweise 53 tex (die Feinheit NM (Nummer metrisch) von 15/2 bis 60/2, vorzugsweise 38/2) aufweist.The warp and the weft yarn of the fabric is advantageously formed of a two-filament yarn having a fineness of 133 tex to 33 tex, preferably 53 tex (the fineness NM (number metric) of 15/2 to 60/2, preferably 38/2) having.

Zweckmäßigerweise ist das Gewebe aus ca. 30 bis 40, vorzugsweise 36 Fäden je cm-Kette und aus ca. 20 bis 35, vorzugsweise 27,5 Fäden je cm-Schuss ausgebildet.Conveniently, the fabric of about 30 to 40, preferably 36 threads per cm-chain and from about 20 to 35, preferably 27.5 threads per cm shot formed.

Der Zweifadenzwirn des Gewebes kann gemäß einer weiteren vorteilhaften Weiterbildung des erfindungsgemäßen Gewebes aus einem Ondégarn oder einem modifizierten Ondégarn aus zwei unterschiedlich dicken Fäden ausgebildet sein. Entsprechend können die beiden Fäden unterschiedliche oder dieselbe Drehrichtung aufweisen.The two-filament yarn of the fabric may, according to a further advantageous development of the fabric according to the invention, be formed of an ond yarn or a modified ond yarn of two differently thick threads. Accordingly, the two threads may have different or the same direction of rotation.

Im Folgenden wird die Erfindung anhand einer Ausführungsform näher beschrieben. Das erfindungsgemäße Gewebe für hitze- und flammfeste Schutzkleidung und gegen Lichtbögen wird insbesondere für die Ausgestaltung von Schutzbekleidungsstücken verwendet, die bei Schweißarbeiten, Arbeiten im Strombereich, Feuerwehrarbeiten und ähnlichen Tätigkeiten eingesetzt werden. Die Gesamtmischung des Kett- und Schussgarns des Gewebes enthält ca. 15 Gew.-% Paraaramid, ca. 43,4 Gew.-% Metaaramid, ca. 40,6 Gew.-% Viskose FR und ca. 1 Gew.-% Antistatikum.The invention will be described in more detail below with reference to an embodiment. The fabric according to the invention for heat- and flame-resistant protective clothing and against electric arcs is used in particular for the design of protective garments which are used in welding, work in the field of electricity, fire-fighting and similar activities. The total mixture of the warp and weft yarn of the fabric contains about 15% by weight of para-aramid, about 43.4% by weight of meta-aramid, about 40.6% by weight of viscose FR and about 1% by weight of antistatic agent ,

Das Gewebe ist als gleichseitiger Kreuzköper 2/2 ausgebildet. Hierdurch ergeben sich vorteilhafte Auswirkungen hinsichtlich der Widerstandsfähigkeit des Gewebes gegen aufprallende Metallspritzer bzw. -tropfen, Strahlungs- und Kontakthitze und die Beaufschlagung mit Lichtbögen.The fabric is designed as an equilateral Kreuzköper 2/2. This results in advantageous effects in terms of the resistance of the fabric against impacting metal splash or droplets, radiation and contact heat and the application of arcs.

An der Innenseite des Gewebes, d.h., an derjenigen Seite, an der das Gewebe der zu schützenden Person zugewandt ist, ist das Gewebe zusätzlich aufgerauht. Die daraus resultierende ausgeprägt räumliche Struktur an der der zu schützenden Person zugewandten Innenfläche des Gewebes hat zur Folge, dass deutlich mehr als 25 flüssige Metalltropfen auf das Gewebe auftreffen können, ohne dass hierdurch der Träger des betreffenden Kleidungsstücks gefährdet würde. Die entsprechende Euronorm EN 11611 Klasse 2 wird durch ein entsprechend ausgestaltetes Schutzbekleidungsstück somit erfüllt. Mit einem entsprechend gestalteten Schutzbekleidungsstück vorgenommene Versuche haben ergeben, daß Schutz gegen mehr als 25 flüssige Metalltropfen, z.B. gegen 27 flüssige Metalltropfen, gesichert ist.On the inside of the fabric, ie, on the side on which the fabric of the person to be protected faces, the fabric is additionally roughened. The resulting pronounced spatial structure at the inner surface of the tissue facing the person to be protected has the consequence that significantly more than 25 liquid drops of metal can impinge on the fabric, without this would endanger the wearer of the garment in question. The corresponding Euronorm EN 11611 class 2 is thus fulfilled by a correspondingly designed protective clothing piece. With a suitably designed protective garment experiments have shown that protection against more than 25 liquid metal drops, for example against 27 liquid metal drops, is secured.

Das Kett- und Schussgarn des Gewebes ist aus Zweifadenzwirn mit der Feinheit 53 tex / NM 38/2 ausgebildet. Je cm-Kette sind ca. 36 Fäden, je cm-Schuss ca. 27,5 Fäden vorgesehen. Der Zweifadenzwirn ist als modifizierter Ondézwirn aus zwei unterschiedlich dicken Fäden ausgebildet.The warp and weft yarn of the fabric is formed of two-thread yarn with a fineness of 53 tex / NM 38/2. Per cm chain are about 36 threads, per cm shot about 27.5 threads provided. The Zweifadenzwirn is formed as a modified Ondézwirn from two different thick threads.
