Description

Die Erfindung bezieht sich auf hitze- und flammfeste Schutzkleidung mit einem Gewebe nach dem Oberbegriff des Patentanspruchs, 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, Paraaramid, Viskose FR (Flame Retardant) und Antistatikum enthält. Ein solches Gewebe ist aus der DE 298 05 867 U1 bekannt.The invention relates to heat- and flame-resistant protective clothing with a fabric according to the preamble of the claim, in particular in welding, work, in which a protection against electric arcs is to ensure firefighting operations, there as duty and / or mission clothing, and similar activities from a yarn whose total mixture contains meta-aramid, para-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, hitze- und flammfeste Schutzkleidung mit einem Gewebe zu schaffen, mittels dem insbesondere der Aufprall von Metallspritzern und Lichtbögen hitzetechnisch noch besser zu beherrschen ist, so dass die für derartige Schutzbekleidung geltende Euronorm EN 11611 Klasse 2 erfüllt wird und entsprechend ausgestaltete Kleidungsstücke Schutz für deutlich mehr als 25 auftreffende flüssige Metalltropfen bieten.Based on the above-described prior art, the present invention seeks to provide heat- and flame-resistant protective clothing with a tissue by means of which in particular the impact of metal spatters and arcs heat control is even better to control, so that the applicable for such protective clothing Euronorm EN 11611 Class 2 is met and appropriately designed garments provide protection for well over 25 impinging liquid metal drops.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, dass das Gewebe als gleichseitiger Kreuzköper 2/2 ausgebildet ist, dass die Gesamtmischung des Garns 15 Gew.-% Paraaramid, 43,4 Gew.-% Metaaramid, 40,6 Gew.-% Viskose FR und etwa 1 Gew.-% Antistatikum enthält, dass das Garn aus aus einem Ondegarn oder einem modifizierten Ondegarn aus zwei unterschiedlich dicken Fäden ausgebildetem Zweifadenzwirn mit der Feinheit NM (Nummer metrisch) von 38/2 (53 tex) ausgebildet ist, dass das Gewebe aus 36 Fäden je cm-Kette und 27,5 Fäden je cm-Schuss ausgebildet ist, und dass das Gewebe an der der zu schützenden Person zugewandten Seite aufgerauht ist.This object is achieved in that the fabric is formed as an equilateral Kreuzköper 2/2 that the total mixture of the yarn 15 wt .-% paraaramid, 43.4 wt .-% meta-aramid, 40.6 wt .-% viscose FR and about 1 wt .-% antistatic contains that the yarn is formed from a Ondegarn or a modified Ondegarn of two differently thick threads trained Zweifadenzwirn with the fineness NM (number metric) of 38/2 (53 tex) that the tissue from 36 threads per cm chain and 27.5 threads per cm shot is formed, and that the tissue is roughened on the side facing the person to be protected roughened.

Hierdurch werden die Widerstandsfähigkeit des Gewebes gegen aufprallende Metallspritzer bzw. -tropfen und die Isolation gegen die auftreffende Hitze erhöht. Da 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 Bekleidungsstücks.This will increase the fabric's resistance to impacting metal splash or drops and insulation increased against the impending heat. As 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.

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.

Die beiden Fäden des Zweifadenzwirns des Gewebes können unterschiedliche oder dieselbe Drehrichtung aufweisen.The two threads of the Zweifadenzwirns of the fabric may have different or the same direction of rotation.

Im Folgenden wird die Erfindung anhand einer Ausführungsform näher beschrieben. Die hitze- und flammfeste Schutzkleidung wird insbesondere bei Schweißarbeiten, Arbeiten im Strombereich, Feuerwehrarbeiten und ähnlichen Tätigkeiten eingesetzt. Die Gesamtmischung des Kett- und Schussgarns des Gewebes enthält 15 Gew.-% Paraaramid, 43,4 Gew.-% Metaaramid, 40,6 Gew.-% Viskose FR und 1 Gew.-% Antistatikum.The invention will be described in more detail below with reference to an embodiment. The heat- and flame-resistant protective clothing is used in particular for welding work, work in the electricity sector, fire brigade work and similar activities used. The total blend of the warp and weft yarn of the fabric contains 15% by weight of para-aramid, 43.4% by weight of meta-aramid, 40.6% by weight of rayon FR and 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, i.e. on the side to 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 fabric facing the person to be protected has the consequence that significantly more than 25 liquid metal drops can strike the fabric without endangering the wearer of the garment in question. The corresponding Euronorm EN 11611 class 2 is thus fulfilled by a correspondingly designed protective clothing piece. Experiments made with a suitably designed garment have revealed that protection against more than 25 liquid metal drops, e.g. 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 36 Fäden, je cm-Schuss 27,5 Fäden vorgesehen. Der Zweifadenzwirn ist als modifizierter Ondezwirn 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 36 threads, per cm shot 27.5 threads provided. The Zweifadenzwirn is designed as a modified Ondezwirn of two different thick threads.
