Description

Die vorliegende Erfindung betrifft einen atmungsaktiven Schutzhandschuh mit Schutzfunktion gegenüber chemischen Giften, insbesondere chemischen Kampfstoffen, nach dem Oberbegriff des Anspruchs 1, insbesondere für den militärischen Einsatz oder für den ABC-Einsatz.The present invention relates to a breathable protective glove with protective function against chemical toxins, in particular chemical warfare agents, according to the preamble of claim 1, in particular for military use or for ABC use.

Es gibt eine Reihe von Stoffen, die von der Haut aufgenommen werden und zu schweren körperlichen Schäden führen. Als Beispiel seien das blasenziehende Lost (Gelbkreuz) und das Nervengift Sarin erwähnt. Menschen, die mit solchen Giften in Kontakt kommen können, müssen eine geeignete Schutzausrüstung tragen bzw. durch geeignete Schutzmaterialien gegen diese Gifte geschützt werden.There are a number of substances that are absorbed by the skin and cause serious physical injury. As an example, the blistering Lost (yellow cross) and the nerve agent sarin are mentioned. People who may come into contact with such toxins must wear suitable protective equipment or be protected by suitable protective materials against these toxins.

Zum Schutz des Körpers, insbesondere der Extremitäten und des Rumpfes, gibt es entsprechende Schutzanzüge. Zum Schutz des Kopfes, insbesondere des Gesichtes, sowie der Atemwege werden im allgemeinen Gasmasken (ABC-Schutzmasken), gegebenenfalls zusammen mit Kapuzen, getragen.To protect the body, especially the extremities and the trunk, there are appropriate protective suits. To protect the head, in particular the face, as well as the respiratory tract, gas masks (ABC protective masks), possibly together with hoods, are generally worn.

Des weiteren ist aber auch darauf zu achten, daß auch die Hände mit einem ausreichenden Schutz gegenüber solchen Giften ausgestattet werden, insbesondere durch das Tragen von Schutzhandschuhen. Insbesondere muß ein solch schützender Handschuh für den militärischen Einsatz oder den ABC-Einsatz geeignet sein.Furthermore, it is also important to ensure that the hands are provided with sufficient protection against such toxins, especially by wearing protective gloves. In particular, such a protective glove must be suitable for military use or ABC use.

Zu diesem Zweck werden gemäß dem Stand der Technik für den militärischen Einsatz bzw. den ABC-Einsatz luft- und wasserdichte Gummihandschuhe, insbesondere auf Butylgummibasis, eingesetzt, welche gegenüber chemischen Giften, insbesondere chemischen Kampfstoffen, undurchlässig sind. Nachteil dieser Schutzhandschuhe ist die mangelnde Atmungsaktivität und der folglich nur geringe Tragekomfort, was insbesondere bei längeren Einsätzen hinderlich ist.For this purpose, according to the prior art for military use or ABC use air and waterproof rubber gloves, in particular on butyl rubber base, used, which are impermeable to chemical toxins, especially chemical warfare agents. Disadvantage of this protective gloves is the lack of breathability and consequently low wearing comfort, which is a hindrance, especially for longer use.

Die auf die Anmelderin selbst zurückgehende US 6 301 715 B1 bzw. die zu derselben Patentfamilie gehörende WO 01/82728 A1 und DE 201 21 518 U1 beschreiben einen Handschuh für Piloten mit erhöhter Taktilität und Schutzwirkung gegenüber chemischen Giften, der aus einem atmungsaktiven Außenmaterial, wie z. B. Leder oder einem Textilmaterial, besteht und mit einer aktivkohlebasierten Adsorptionsschicht zur Adsorption chemischer Kampfstoffe ausgerüstet sein kann. Dieser Handschuh bietet aufgrund der aktivkohlebasierten Adsorptionsschicht zwar eine exzellente Schutzfunktion gegenüber chemischen Giften, insbesondere Kampfstoffen, jedoch ist die Tragezeit dieses Handschuhs bei einem militärische bzw. ABC-Einsatz aufgrund der begrenzten Adsorptionskapazität der Aktivkohle beschränkt. Des weiteren ist dieser. Handschuh nicht ohne weiteres dekontaminierbar bzw. regenerierbar.The originating from the applicant itself US 6 301 715 B1 or belonging to the same patent family WO 01/82728 A1 and DE 201 21 518 U1 describe a glove for pilots with increased tactility and protection against chemical toxins, which consists of a breathable outer material, such as As leather or a textile material, and can be equipped with an activated carbon adsorption layer for adsorption of chemical warfare agents. Although this glove offers an excellent protective function against chemical poisons, in particular warfare agents, due to the activated carbon-based adsorption layer, the wearing time of this glove is limited in a military or ABC use due to the limited adsorption capacity of the activated carbon. Furthermore, this one is. Glove not easily decontaminable or regenerable.

Weiterhin beschreibt die FR 2 752 994 A1 einen Schutzhandschuh gegen nukleare, biologische und chemische Schadstoffe mit einer inneren Filterschicht, welche Aktivkohle enthält und auf einen Stoffträger aufgeklebt ist. Der Schutzhandschuh weist eine äußere Schicht aus Baumwolle/Polyester auf, welche teilweise einer hydrooleofugen Behandlung unterzogen wird.Furthermore, the describes FR 2 752 994 A1 a protective glove against nuclear, biological and chemical pollutants with an inner filter layer containing activated carbon and adhered to a fabric carrier. The protective glove has an outer layer of cotton / polyester, which is partially subjected to a Hydrooleofugen treatment.

Es ist daher die Aufgabe der vorliegenden Erfindung, einen Schutzhandschuh, insbesondere einen atmungsaktiven Schutzhandschuh, mit Schutzfunktion gegenüber chemischen Giften, insbesondere chemischen Kampfstoffen, bereitzustellen, welcher sich insbesondere für den militärischen Einsatz oder den ABC-Einsatz eignet und die zuvor geschilderten Nachteile des Standes der Technik zumindest teilweise vermeidet.It is therefore an object of the present invention to provide a protective glove, in particular a breathable protective glove, with protective function against chemical toxins, in particular chemical warfare agents, which is particularly suitable for military use or ABC use and the disadvantages of the prior Technology at least partially avoids.

Eine weitere Aufgabe der vorliegenden Erfindung besteht darin, den in der US 6 301 715 B1 bzw, in den beiden vorgenannten parallelen Schutzrechtsanmeldungen WO 01/82728 A1 und DE 201 21 518 U1 beschriebenen Handschuh weiterzuentwickeln.Another object of the present invention is that in the US 6,301,715 B1 resp., In the two aforementioned parallel patent applications WO 01/82728 A1 and DE 201 21 518 U1 further developed glove.

Zur Lösung der zuvor geschilderten Aufgabenstellung schlägt die vorliegende Erfindung einen Schutzhandschuh, insbesondere einen atmungsaktiven Schutzhandschuh (z. B. Militärschutzhandschuh oder ABC-Schutzhandschuh), gemäß Anspruch 1 vor. Weitere, vorteilhafte Ausgestaltungen des erfindungsgemäßen Schutzhandschuhs sind Gegenstand der Unter- und Nebenansprüche.To solve the above-described problem, the present invention proposes a protective glove, in particular a breathable protective glove (eg military protective glove or ABC protective glove) according to claim 1. Further, advantageous embodiments of the protective glove according to the invention are the subject of the dependent claims.

Die grundlegende Idee der vorliegenden Erfindung besteht darin, einen atmungsaktiven Schutzhandschuh mit mehrschichtigem Schichtaufbau mit einer insbesondere flächigen, außenseitigen Trägerschicht und einer der Trägerschicht zugeordneten, den Durchtritt chemischer Gifte verhindernden oder zumindest verzögernden, innenseitigen (d. h. im Tragezustand der Hand zugewandten) Sperrschicht, welche eine Adsorptionsschicht auf Basis eines chemische Gifte adsorbierenden Adsorptionsmaterials (z. B. auf Basis von Aktivkohle) umfaßt, dadurch mit einer erhöhten bzw. verbesserten Schutzfunktion gegenüber chemischen Giften, insbesondere chemischen Kampfstoffen, auszurüsten, daß die Sperrschicht zusätzlich zu der Adsorptionsschicht mit einer zumindest im wesentlichen wasser- und luftundurchlässigen, aber wasserdampfdurchlässigen, den Durchtritt chemischer Gifte verzögernden oder gegenüber chemischen Giften zumindest im wesentlichen undurchlässigen Membran, welche zwischen der Trägerschicht und der Adsorptionsschicht angeordnet wird, ausgestattet wird.The basic idea of the present invention is to provide a breathable protective glove with a multilayered layer structure having a particular flat, outside carrier layer and a barrier layer which prevents, or at least retards, the inner side (ie, in the carrying state of the hand facing) the barrier layer associated with the carrier layer and which has a Adsorption layer based on a adsorbent adsorbent material (eg based on activated charcoal) comprising chemical poisons, thereby providing an enhanced function of protection against chemical poisons, in particular chemical warfare agents, that the barrier layer in addition to the adsorption at least substantially water-impermeable, but permeable to water vapor, the passage of chemical poisons retarding or at least substantially impermeable to chemical poisons membrane which between the Trägersch and the adsorption layer is arranged.

Die vorgenannte Membran, welche zwischen der Trägerschicht und der Adsorptionsschicht angeordnet wird, bewirkt, daß gegebenenfalls durch die außenseitige Trägerschicht eingedrungene chemische Gifte, wie z. B. chemische Kampfstoffe, die Adsorptionsschicht nicht oder zumindest zu einem überwiegenden Teil gar nicht erst erreichen, so daß die Adsorptionskapazität der Adsorptionsschicht quasi unetschöpflich bleibt. Durch die Ausstattung des erfindungsgemäßen Schutzhandschuhs mit einer speziellen atmungsaktiven Membran, welche den Durchtritt chemischer Gifte verzögert bzw. gegenüber chemischen Giften zumindest im wesentlichen undurchlässig ist, wird gleichzeitig eine gute Dekontaminierbarkeit und Regenerierbarkeit des erfindungsgemäßen Schutzhandschuhs erreicht.The aforementioned membrane, which is arranged between the carrier layer and the adsorption, causes any chemical poisons which may have penetrated through the outside carrier layer, such as e.g. As chemical warfare agents, the adsorption or not reach at least for the most part not at all, so that the adsorption capacity of the adsorption remains virtually inexhaustible. By equipping the protective glove according to the invention with a special breathable membrane, which delays the passage of chemical poisons or at least substantially impermeable to chemical poisons, a good decontamination and regenerability of the protective glove according to the invention is achieved.

Fig. 1 zeigt einen erfindungsgemäßen atmungsaktiven Schutzhandschuh 1 mit Schutzfunktion gegenüber chemischen Giften, insbesondere gegenüber chemischen Kampfstoffen. Der erfindungsgemäße Schutzhandschuh 1 weist einen mehrschichtigen Schichtaufbau 2 mit einer insbesondere flächigen, außenseitigen Trägerschicht 3 und einer der Trägerschicht 3 zugeordneten, innenseitigen (d. h. im Tragezustand der Hand zugewandten), den Durchtritt chemischer Gifte verhindernden oder zumindest verzögernden Sperrschicht 4 auf, welche eine Adsorptionsschicht 5 auf Basis eines chemische Gifte adsorbierenden Adsorptionsmaterials, insbesondere auf Basis von Aktivkohle, umfaßt. Zusätzlich zu der Adsorptionsschicht 5 weist die Sperrschicht 4 eine zumindest im wesentlichen wasser- und luftundurchlässige, aber wasserdampfdurchlässige (d. h. atmungsaktive), den Durchtritt chemischer Gifte verzögernde oder gegenüber chemischen Giften zumindest im wesentlichen undurchlässige Membran 6 auf, welche zwischen der Trägerschicht 3 und der Adsorptionsschicht 5 angeordnet ist. Urfindujigsgemäß umfaßt die Sperrschicht 4 also sowohl eine Adsorptionsschicht 5 als auch eine Membran 6 mit den vorgenannten Eigenschaften. Durch die Kombination von Adsorptionsschicht 5 einerseits und Membran 6 andererseits entsprechend dem erfindungsgemäßen Schichtaufbau 2 wird ein effizienter Schutz gegenüber chemischen Gifte, insbesondere chemischen Kampfstoffen, bei gleichzeitig hohem Tragekomfort, insbesondere Atmungsaktivität, gewährleistet. Fig. 1 shows a breathable protective glove 1 according to the invention with protective function against chemical toxins, in particular against chemical warfare agents. The protective glove 1 according to the invention has a multi-layered layer structure 2 with a particular flat, outer side carrier layer 3 and an inner side (ie, in the wear state of the hand facing), the passage of chemical poisons preventing or at least retarding barrier layer 4, which an adsorption 5 Based on a chemical poisons adsorbing adsorbent material, in particular based on activated carbon, comprises. In addition to the adsorption layer 5, the barrier layer 4 has an at least substantially water and air impermeable, but water vapor permeable (ie breathable) chemical vapor retardant or at least substantially impermeable to chemical poisons membrane 6 sandwiched between the support layer 3 and the adsorbent layer 5 is arranged. According to Urfindujigs accordingly the barrier layer 4 comprises both an adsorption layer 5 and a membrane 6 with the aforementioned properties. The combination of adsorption layer 5, on the one hand, and membrane 6, on the other hand, according to the layer structure 2 according to the invention, ensures efficient protection against chemical poisons, in particular chemical warfare agents, with simultaneously high wearing comfort, in particular breathability.

Wie aus den Fig. 1 sowie 2A und 2B ersichtlich, wird durch die erfindungsgemäße Anordnung der Membran 6 zwischen der Trägerschicht 3 und der Adsorptionsschicht 5 erreicht, daß gegebenenfalls durch die äußere Trägerschicht 3 des Schutzhandschuhs 1 eingedrungene Gifte bereits von der Membran 6 zurückgehalten werden und folglich die Adsorptionsschicht 5 gar nicht erst erreichen oder allenfalls in äußerst geringen Mengen; auf diese Weise wird zum einen die Adsorptionskapazität der Adsorptionsschicht quasi niemals erschöpft, und zum anderen wird durch die Anwesenheit der Membran 6 ein zusätzlicher Schutz für den Träger des Schutzhandschuhs 1 bereitgestellt, so daß ein Schutzhandschuh 1 mit sozusagen doppelter Schutzfunktion gegenüber chemischen Giften resultiert (nämlich einerseits durch die Sperrwirkung der Membran 6 und andererseits durch die Adsorptionswirkung der Adsorptionsschicht 5). Durch die Anwesenheit der speziellen Membran 6 wird zudem erreicht, daß der Schutzhandschuh 1 dekontaminierbar und regenerierbar wird; denn durch die Außenschicht 3 gegebenenfalls eingedrungene Gifte können durch entsprechende Behandlungsverfahren von der Membran 6 wieder entfernt werden (z. B. durch Herunterspülen), beispielsweise mit geeigneten Dekontaminationslösungen, welche dem Fachmann zu diesen Zwecken bestens bekannt sind.Like from the Fig. 1 2A and 2B, the inventive arrangement of the membrane 6 between the carrier layer 3 and the adsorption layer 5 ensures that poisons which may have penetrated through the outer carrier layer 3 of the protective glove 1 are already retained by the membrane 6 and consequently the adsorption layer 5 is not only reach or at best in extremely small quantities; In this way, on the one hand the adsorption capacity of the adsorption virtually never exhausted, and on the other hand, the presence of the membrane 6, an additional protection for the wearer of the protective glove 1 is provided so that a protective glove 1 with so-to-double protection against chemical toxins results (namely on the one hand by the blocking effect of the membrane 6 and on the other hand by the adsorption effect of the adsorption layer 5). Due to the presence of the special membrane 6 is also achieved that the protective glove 1 is decontaminated and regenerable; since poisons which may have penetrated through the outer layer 3 can be removed again from the membrane 6 by appropriate treatment methods (eg by flushing), for example with suitable decontamination solutions which are well known to the person skilled in the art for these purposes.

Wie aus den Fig. 1 sowie 2A und 2B ersichtlich, ist die Membran 6 bzw. die Sperrschicht 4 an ihrer im Tragezustand von der Hand abgewandten Seite mittelbar mit der Trägerschicht 3 verbunden. Die im Tragezustand der Hand zugewandte bzw. der Trägerschicht 3 abgewandte Seite (d. h also der Innenseite) der Membran 6 ist dagegen mit der Adsorptionsschicht 5 beaufschlagt; im allgemeinen ist die Adsorptionsschicht 5 mittels Klebstoffauftrag 7 an der Membran 6 befestigt. Wie die Fig. 2A und 2B zeigen, kann dabei der Klebstoffauftrag 7 grundsätzlich diskontinuierlich (Fig. 2A) oder aber kontinuierlich bzw. vollflächig (Fig. 2B) erfolgen. Bevorzugt ist jedoch ein diskontinuierlicher, insbesondere punktförmiger Klebstoffauftrag entsprechend Fig. 2A, weil dies den Tragekomfort des erfindungsgemäßen Schutzhandschuhs 1 erhöht, insbesondere eine zusätzliche Steifigkeit der Membran 6 verhindert, wie dies im Fall eines vollflächigen bzw. kontinuierlichen Klebstoffauftrags der Fall sein kann. Dennoch ist es grundsätzlich möglich, einen vollflächigen bzw. kontinuierlichen Klebstoffauftrag 7 zu Zwecken der Befestigung der Adsorptionsschicht 5 an der Membran 6 vorzusehen; in diesem Fall sollte aber darauf geachtet werden, daß der Klebstoff 7 atmungsaktive Eigenschaften aufweist, insbesondere wasserdampfdurchlässig ist, um den nötigen Tragekomfort zu gewährleisten.Like from the Fig. 1 2A and 2B, the membrane 6 or the barrier layer 4 is indirectly connected to the carrier layer 3 on its side facing away from the hand in the carrying state. On the other hand, the side facing the wearer's hand or the support layer 3 facing away from the diaphragm 6 (ie, the inside) of the membrane 6 is charged with the adsorption layer 5; In general, the adsorption layer 5 is attached to the membrane 6 by means of adhesive application 7. As the FIGS. 2A and 2B In this case, the adhesive application 7 can in principle be discontinuous ( Fig. 2A ) or continuously or completely ( Fig. 2B ) respectively. However, a discontinuous, in particular punctiform adhesive application is preferred accordingly Fig. 2A because this increases the wearing comfort of the protective glove 1 according to the invention, in particular prevents additional rigidity of the membrane 6, as may be the case in the case of a full-surface or continuous adhesive application. Nevertheless, it is in principle possible to provide a full-area or continuous adhesive application 7 for purposes of securing the adsorption layer 5 to the membrane 6; but in this case, care should be taken be that the adhesive 7 has breathable properties, in particular water vapor permeable, to ensure the necessary comfort.

Des weiteren ist es vorgesehen, daß zwischen der Membran 6 und der Trägerschicht 3 eine zusätzliche, vorzugsweise flächige Trägerschicht 8 angeordnet ist. Auf diese Weise ist die Membran 6 nur mittelbar mit der Trägerschicht 3 verbunden, und zwar über die zusätzliche Trägerschicht 8. Die zusätzliche Trägerschicht 8 dient zur Stabilisierung und/oder Stützung der Membran 6, und zwar sowohl bei der Verarbeitung der Membran 6, insbesondere bei der Beaufschlagung mit Klebstoff 7 und der Adsorptionsschicht 5, als auch im Gebrauch bzw. beim Tragen des Schutzhandschuhs 1. Durch die zusätzliche Trägerschicht 8 wird insbesondere die Verschleißbeständigkeit, so z. B. die Reißfestigkeit, der Membran 6 gesteigert. Zu diesem Zweck ist die Membran 6 auf die zusätzliche Trägerschicht auflaminiert oder aufkaschiert, und zwar mittels eines Klebstoffs (in den Zeichnungen nicht dargestellt), der punktförmig aufgetragen wird, weil dies eine übermäßige Steifigkeit der Membran 6 verhindert und auf diese Weise der Tragekomfort erhöht wird. Die zusätzliche Trägerschicht 8, die zwischen der Membran 6 und der äußeren Trägerschicht 3 angeordnet ist, kann dann mit der Trägerschicht 3 verbunden werden, üblicherweise mittels eines vorzugsweise diskontinuierlich, insbesondere punktförmig aufgetragenen Klebstoffes. Als Materialien für die zusätzliche Trägerschicht 8 eignen sich beispielsweise Textilmaterialien, insbesondere textile Flächengebilde, wie z. B. Gewebe, Gewirke, Gestricke, Gelege oder Terctilverbundstoffe (z. B. Vliesstoffe), die vorzugsweise luftdurchlässig ausgebildet sind. Erfindungsgemäß hat die zusätzliche Trägerschicht 8 ein geringeres Flächengewicht als die Trägerschicht 3. Im allgemeinen beträgt das Flächengewicht der zusätzlichen Trägerschicht 8 weniger als 60 g / m2, insbesondere weniger als 50 g / m2, vorzugsweise weniger als 40 g / m2; dies trägt zu einen erhöhten Tragekomfort bei, weil auf diese Weise die Biegsamkeit des Schichtaufbaus 2 insgesamt im wesentlichen nicht beeinträchtigt wird und ein guter Tragekomfort erzielt wird.Furthermore, it is provided that between the membrane 6 and the support layer 3, an additional, preferably flat carrier layer 8 is arranged. In this way, the membrane 6 is only indirectly connected to the carrier layer 3, via the additional carrier layer 8. The additional carrier layer 8 serves to stabilize and / or support the membrane 6, both in the processing of the membrane 6, in particular at the application of adhesive 7 and the adsorption layer 5, as well as in use or when wearing the protective glove 1. The additional support layer 8 in particular the wear resistance, such. As the tensile strength, the membrane 6 increased. For this purpose, the membrane 6 is laminated or laminated on the additional support layer by means of an adhesive (not shown in the drawings) which is applied in a point-like manner, because this prevents excessive rigidity of the membrane 6 and in this way increases the wearing comfort , The additional carrier layer 8, which is arranged between the membrane 6 and the outer carrier layer 3, can then be joined to the carrier layer 3, usually by means of a preferably discontinuous, in particular punctiform, applied adhesive. As materials for the additional carrier layer 8, for example, textile materials, in particular textile fabrics such. As wovens, knits, knits, scrims or Terctilverbundstoffe (eg., Nonwovens), which are preferably designed to be permeable to air. According to the invention, the additional carrier layer 8 has a lower basis weight than the carrier layer 3. In general, the weight per unit area of the additional carrier layer 8 is less than 60 g / m 2 , in particular less than 50 g / m 2 , preferably less than 40 g / m 2 ; This contributes to an increased wearing comfort, because in this way the flexibility of the layer structure 2 as a whole is not substantially impaired and a good wearing comfort is achieved.

Wie zuvor geschildert, ist die Membran 6 innenseitig (d. h. auf der im Tragezustand der Hand zugewandten Seite) mit einer Adsorptionsschicht 5 beaufschlagt. Die Adsorptionsschicht 5 wiederum kann auf ihrer im Tragezustand der Hand zugewandten, d. h. also der Membran 6 abgewandten Seite mit einer Abdeckschicht 9 versehen sein, die vorteilhafterweise an der Adsorptionsschicht 5 befestigt ist; zur Befestigung der Abdeckschicht 9 an der Adsorptionsschicht 5 eignen sich beispielsweise Klebstoffe, die zu diesen Zwecken vorzugsweise diskontinuierlich, insbesondere punktförmig, auf der Abdeckschicht 9 aufgetragen werden, oder aber sogenannte Schmelzklebergewebe ("Schmelzkleberwebs"), welche zwischen Abdeckschicht 9 und Adsorptionsschicht 5 angeordnet werden, Als Abdeckschicht 9 eignen sich vorzugsweise luftdurchlässige Textilmaterialien, insbesondere textile Flächengebilde, wie Gewebe, Gewirke, Gestricke, Gelege oder Textilverbundstoffe (z. B. Vliese, insbesondere polyamid/Polyester-Vliese bzw. PA/PES-Vliese). Vorteilhafterweise ist das Abdeckmaterial 9 abriebfest ausgebildet bzw. besteht aus einem abriebfesten Textilmaterial. Vorteilhafterweise besitzt das Abdeckmaterial 9 ein Flächengewicht von 5 bis 150 g / m2, insbesondere 10 bis 125 g/ m2, vorzugsweise 40 bis 100 g/m2. Die Anwesenheit des Abdeckmaterials bzw. der Abdeckschicht 9 hat insbesondere den Vorteil, daß ein unmittelbarer Kontakt der Haut bzw. der Hand mit der Adsorptionsschicht 5 beim. Tragen des Schutzhandschuhs 1 vermieden wird; dadurch wird einerseits bewirkt, daß die Adsorptionsschicht 5 nicht durch Hautschweiß verunreinigt wird, und zum anderen wird ein höherer Tragekomfort erzielt, weil die Abdeckschicht 9 im Rahmen des erfindungsgemäßen Schichtaufbaus 2 die Punktion eines textilen Innenhandschuhs einnimmt, welcher ein angenehmes Tragegefühl bewirkt. Zum anderen verhindert die Abdeckschicht 9 eine übermäßige mechanische Belastung des Adsorptionsmaterials der Adsorptionsschicht.As described above, the membrane 6 is acted upon on the inside (ie on the side facing the wearer in the carrying state) with an adsorption layer 5. The adsorption layer 5, in turn, may be provided with a covering layer 9 on its side facing the hand in the wearing state, ie, facing away from the membrane 6, which is advantageously fastened to the adsorption layer 5; For example, adhesives which are preferably applied intermittently, in particular punctiform, on the cover layer 9 or else so-called hot melt adhesive webs ("hot melt adhesive webs") which are arranged between the cover layer 9 and the adsorption layer 5 are suitable for fastening the cover layer 9 to the adsorption layer 5 "Air-permeable textile materials, in particular textile fabrics, such as woven, knitted or knitted fabrics, scrims or textile composites (eg nonwovens, in particular polyamide / polyester nonwovens or PA / PES nonwovens) are preferably suitable as covering layer 9. Advantageously, the cover 9 is formed abrasion resistant or consists of an abrasion-resistant textile material. Advantageously, the covering material 9 has a weight per unit area of 5 to 150 g / m 2 , in particular 10 to 125 g / m 2 , preferably 40 to 100 g / m 2 . The presence of the covering material or the covering layer 9 has the particular advantage that a direct contact of the skin or the hand with the adsorption 5 during. Wearing the protective glove 1 is avoided; This on the one hand causes the adsorption layer 5 is not contaminated by sweat, and on the other hand, a higher comfort is achieved because the cover layer 9 in the context of the layer structure 2 of the invention occupies the puncture of a textile inner glove, which causes a comfortable fit. On the other hand, the covering layer 9 prevents excessive mechanical loading of the adsorption material of the adsorption layer.

Wie zuvor beschrieben, ist die Membran 6 außenseitig (d. h. auf der im Tragezustand der Hand abgewandten Seite) mit der zusätzlichen Trägerschicht 8 verklebt. Vorteilhafterweise erfolgt die Verklebung nur diskontinuierlich, nämlich punktförmig, insbesondere in Form eines punktförmigen Rasters oder Musters, wobei der Klebstoff nur höchstens 30 %, insbesondere nur höchstens 25 %, vorzugsweise nur höchstens 20 %, besonders bevorzugt nur höchstens 10 % der im Tragezustand von der Hand abgewandten Seite der Membran 6 bedeckt.As described above, the membrane 6 is glued to the outside (ie, on the side facing away from the hand in the carrying state) with the additional carrier layer 8. Advantageously, the bonding takes place only discontinuously, namely punctiform, in particular in the form of a dot-shaped raster or pattern, wherein the adhesive only 30% at most, in particular only at most 25%, preferably only at most 20%, more preferably only at most 10% in the state of wear of the Hand facing away from the membrane 6 covered.

Innenseitig (d. h. auf der im Tragezustand der Hand zugewandten Seite) ist auf die Membran 6 die Adsorptionsschicht 5 aufgebracht, insbesondere mittels eines Klebstoffs 7; der Auftrag des Klebstoffs 7 erfolgt - wie zuvor geschildert - vorteilhafterweise diskontinuierlich, insbesondere nur punktförmig, üblicherweise in Form eines punktförmigen Rasters, wobei zur Erzielung einer hohen Adsorptionsleistung mindestens 50 %, insbesondere mindestens 60 %, vorzugsweise mindestens 70 %, besonders bevorzugt mindestens 75 %, ganz besonders bevorzugt mindestens 80 % der im Tragezustand der Hand zugewandten, d. h. also der Trägerschicht 3 abgewandten Seite der Membran 6 mit dem Adsorptionsmaterial der Adsorptionsschicht 5 bedeckt bzw. beaufschlagt sein kann; entsprechend ist der Klebstoffauftrag 7 über diese Flächenbereiche der Membran 6 vorzusehen. Für den Fall, daß als Adsorptionsmaterial der Adsorptionsschicht 5 ein Flächengebilde (Grewebe, Gewirke, Gelege, Vlies etc.) aus Aktivkohlefasern verwendet wird, kann die im Tragezustand der Hand zugewandte, d. h. also der Trägerschicht 3 abgewandte Seite der Membran 6 vollständig, d. h. zu 100 %, mit dem Adsorptionsmaterial der Adsorptionsschicht 5 bedeckt bzw. beaufschlagt sein; das Aktivkohlefasergebilde kann beispielsweise durch nur punktförmigen Klebstoffauftrag an der Membran 6 fixiert sein.On the inside (ie on the side facing the wearer in the carrying state), the adsorption layer 5 is applied to the membrane 6, in particular by means of an adhesive 7; the application of the adhesive 7 takes place-as described above-advantageously discontinuously, in particular only punctiform, usually in the form of a dot-shaped grid, with at least 50%, in particular at least 60%, preferably at least 70%, particularly preferably at least 75%, to achieve a high adsorption performance. , most preferably at least 80% of the hand-facing, d. H. Thus, the support layer 3 opposite side of the membrane 6 may be covered or acted upon with the adsorbent material of the adsorption layer 5; Accordingly, the adhesive application 7 is to be provided over these areas of the membrane 6. In the event that the adsorption of the adsorption layer 5, a fabric (Grewebe, knitted fabric, scrim, fleece, etc.) is used from activated carbon fibers, the in the worn state of the hand facing, d. H. So the carrier layer 3 opposite side of the membrane 6 completely, d. H. 100%, to be covered with the adsorption material of the adsorption layer 5; the activated carbon fiber structure can be fixed to the membrane 6, for example, by only point-wise adhesive application.

Im allgemeinen sind die einzelnen Schichten 3, 4, 5, 6, 8 und 9 des Schichtaufbaus 2 jeweils miteinander verbunden; dies geschieht mit an sich für diese Zwecke bekannten Methoden (z. B. durch Verkleben, Verschweißen, Vernähen, Verheften etc.). Vorteilhafterweise erfolgt das Verbinden bzw. Fixieren der einzelnen Schichten 3, 4, 5, 6, 8 und 9 des Schichtaufbaus 2 jeweils miteinander nahtlos, vorzugsweise ohne Beschädigung der einzelnen Schichten 3, 4, 5, 6, 8 und 9 (z. B. durch Verkleben, Verschweißen etc.). Für den Fall, daß die Schichten 3, 4, 5, 6, 8 und 9 - zumindest teilweise - vernäht oder dergleichen werden, empfiehlt es sich, die Nahtstellen abzudichten (z. B. mit einem sogenannten Nahtversiegelungsband). Insbesondere bilden die einzelnen Schichten 3, 4, 5, 6, 8 und 9 des Schichtaufbaus 2 einen zusammenhängenden Verbund aus.In general, the individual layers 3, 4, 5, 6, 8 and 9 of the layer structure 2 are connected to each other; This is done by methods known per se for this purpose (eg by gluing, welding, sewing, stapling etc.). Advantageously, the bonding or fixing of the individual layers 3, 4, 5, 6, 8 and 9 of the layer structure 2 takes place in each case seamlessly, preferably without damaging the individual layers 3, 4, 5, 6, 8 and 9 (eg. by gluing, welding, etc.). In the event that the layers 3, 4, 5, 6, 8 and 9 are - at least partially - sewn or the like, it is recommended to seal the seams (eg with a so-called seam-sealing tape). In particular, the individual layers 3, 4, 5, 6, 8 and 9 of the layer structure 2 form a coherent composite.

Die einzelnen Schichten 3, 4, 5, 6, 8 und 9 bzw. der Schichtaufbau 2 können bzw. kann sich dabei über die gesamte Hand einschließlich des Handgelenks und eines Teils des unteren Unterarms erstrecken (Fig. 1). Gemäß dieser Ausführungsform bilden die einzelnen Schichten 3, 4, 5, 6, 8 und 9 bzw. der Schichtaufbau 2 einen zusammenhängenden Handschuh in Form einer Hand mit fünf Fingern und einem Schaft, der sich über den Handknöchel hinweg erstreckt.The individual layers 3, 4, 5, 6, 8 and 9 or the layer structure 2 can extend over the entire hand including the wrist and a part of the lower forearm ( Fig. 1 ). According to this embodiment, the individual layers 3, 4, 5, 6, 8 and 9 or the layer structure 2 form a coherent glove in the form of a hand with five fingers and a shaft which extends over the knuckle of the hand.

Vorteilhafterweise ist der Schutzhandschuhs 1 als Fingerhandschuh ausgebildet, weist also die Form einer Hand mit fünf Fingern auf; dies steigert nicht nur den Tragekomfort, sondern erleichtert auch den Einsatz für militärische bzw. ABC-Zwecke. Die Tatsache, daß der erfindungsgemäße Handschuh 1 sich vorteilhafterweise über den Handknöchel hinweg erstreckt (d. h. einen Handschuhschaft aufweist), ermöglicht eine abdichtende Verbindung mit einem gleichzeitig getragenen ABC-Schutzanzug; zu diesem Zweck können der Handschuh und/oder der ABC-Schutzanzug mit entsprechenden Abdichtelementen ausgestattet sein (z. B. Reißverschlüsse, Klettelemente, Dichtlippen etc.), um den Übergang von Schutzhandschuh 1 und ABC-Schutzanzug abzudichten bzw. abdichtend miteinander zu verbinden.Advantageously, the protective glove 1 is designed as a finger glove, thus has the shape of a hand with five fingers on; This not only increases the wearing comfort, but also facilitates the use for military or ABC purposes. The fact that the glove 1 according to the invention advantageously extends over the knuckle (i.e., has a glove shaft) enables a sealing connection with a simultaneously worn ABC protective suit; For this purpose, the glove and / or the ABC protective suit may be provided with appropriate sealing elements (eg zippers, hook-and-loop fasteners, sealing lips, etc.) in order to seal the transition between protective glove 1 and ABC protective suit or to seal them together.

Insbesondere bilden die einzelnen Schichten 3, 4, 8 und 9 dabei jeweils die Form eines Handschuhs mit fünf Fingern aus: Die Abdeckschicht 9 bildet dabei sozusagen einen Innenhandschuh aus, während die Trägerschicht 3 sozusagen einen Außenhandschuh ausbildet. Die Sperrschicht 4 mit innenseitiger Adsorptionsschicht 5 und außenseitiger Membran 6 bildet zusammen mit der zusätzlichen Trägerschicht 8 einen zwischen Innenhandschuh und Außenhandschuh befindlichen Kernhandschuh aus, wobei alle drei Handschuhteile - Außen-, Innen- wie Kernhandschuh - miteinander verbunden sind und gemeinsam den erfindungsgemäßen Schutzhandschuh 1 bilden.In particular, the individual layers 3, 4, 8 and 9 in each case form the shape of a glove with five fingers: the covering layer 9 forms an inner glove, so to speak, while the carrier layer 3 forms, so to speak, an outer glove. The barrier layer 4 with adsorption layer 5 on the inside and outer membrane 6 forms, together with the additional carrier layer 8, a core glove located between inner glove and outer glove, wherein all three glove parts - outer, inner and core glove - are connected together and together form the protective glove 1 according to the invention ,

Was das Material der Trägerschicht 3, die im allgemeinen die Außenschicht des Schutzhandschuhs 1 bildet, anbelangt, so können hier beliebige, insbesondere atmungsaktive Materialien verwendet werden, wie sie für Handschuhe im allgemeinen verwendet werden. Beispiele hierfür sind Textilmaterialien, vorzugsweise luftdurchlässige Textilmaterialien, insbesondere in Form textiler Flächengebilde, so z. B. Gewebe, Gewirke, Gestricke, Gelege oder Textilverbundstoffe. Beispielsweise kann der Textilverbundstoff ein Vlies sein. Alternativ kann die Trägerschicht 3 aber auch als ein Ledermaterial ausgebildet sein. Dabei ist es vorteilhaft, den Außenhandschuh bzw. die Trägerschicht 3 im Bereich der Fingerspitzen nahtlos auszubilden. Für weitere diesbezügliche Einzelheiten kann auf die vorgenannten Dokumente US 6 301 715 B1 bzw. WO 01/82728 A1 und DE 201 21 518 U1 verwiesen werden.As regards the material of the carrier layer 3, which generally forms the outer layer of the protective glove 1, any, in particular breathable, materials as used for gloves in general can be used here. Examples of these are textile materials, preferably air-permeable textile materials, in particular in the form of textile fabrics, such. For example, woven, knitted, knitted, scrim or textile composites. For example, the nonwoven fabric may be a nonwoven. alternative However, the carrier layer 3 may also be formed as a leather material. It is advantageous to form the outer glove or the carrier layer 3 seamlessly in the region of the fingertips. For further details please refer to the above mentioned documents US 6 301 715 B1 respectively. WO 01/82728 A1 and DE 201 21 518 U1 to get expelled.

Um ein Eindringen chemischer Gifte (z. B. konzentrierter Tropfen von Kampfstoffen) zu verhindern bzw. zu erschweren, empfiehlt sich eine Oleophobierung und/oder Hydrophobierung des Materials der äußeren Trägerschicht 3, insbesondere durch eine spezielle Imprägnierung.In order to prevent or aggravate the penetration of chemical poisons (eg concentrated droplets of warfare agents), oleophobization and / or hydrophobing of the material of the outer carrier layer 3 is recommended, in particular by a special impregnation.

Das Material der Trägerschicht 3 bzw. des Außenhandschuhs besitzt im allgemeinen ein Flächengewicht von 50 bis 300 g/ m2, insbesondere 75 bis 250 g/ m2, vorzugsweise 75 bis 175 g/ m2. Insbesondere ist die Trägerschicht 3 als ein luftdurchlässiges, 75 bis 250 g/ m2, vorzugsweise 75 bis 175 g/ m2 schweres textiles Flächengebilde, welches oleophob und/oder hydrophob ausgerüstet sein kann, ausgebildet.The material of the carrier layer 3 or of the outer glove generally has a basis weight of 50 to 300 g / m 2 , in particular 75 to 250 g / m 2 , preferably 75 to 175 g / m 2 . In particular, the carrier layer 3 as an air-permeable, 75 to 250 g / m 2 , preferably 75 to 175 g / m 2 heavy textile fabric, which may be equipped oleophobic and / or hydrophobic formed.

Was die Membran 6 anbelangt, so handelt es sich hierbei im allgemeinen um eine kontinuierliche, insbesondere geschlossene oder allenfalls mikroporöse Membran. Dabei beträgt die Dicke der Membran 6 im allgemeinen 1 bis 500 µm, inbesondere 1 bis 250 µm, vorzugsweise 1 bis 100 µm, bevorzugt 1 bis 50 µm, besonders bevorzugt von 2,5 bis 30 µm, ganz besonders bevorzugt 5 bis 25 µ. Zur Erhöhung des Tragekomforts, insbesondere der Atmungsaktivität, weist die Membran 6 bei 25 °C und bei einer Dicke von 50 µm eine hohe Wasserdampfdurchlässigkeit von mindestens 12,5 1/m2 pro 24 h, insbesondere mindestens 17,5 1/m2 pro 24 h, vorzugsweise mindestens 20 1/m2 pro 24 h oder mehr, auf (gemessen nach der "Methode des umgekehrten Bechers" bzw. "inverted cup method" nach ASTM E 96 und bei 25 °C) (Zu weiteren Einzelheiten zur Messung der Wasserdampfdurchlässigkeit [water vapour transmission, WVT] vgl. auch McCullough et al. "A comparison of standard methods for measuring water vapour permeability of fabrics" in Meas. Sci. Technol. [Measurements Science and Technology] 14, 1402-1408, August 2003 ). Hierdurch wird ein besonders hoher Tragekomfort gewährleistet.As far as the membrane 6 is concerned, this is generally a continuous, in particular closed or at most microporous membrane. The thickness of the membrane 6 is generally 1 to 500 .mu.m, in particular 1 to 250 .mu.m, preferably 1 to 100 .mu.m, preferably 1 to 50 .mu.m, more preferably from 2.5 to 30 .mu.m, most preferably 5 to 25 μ. To increase the wearing comfort, in particular the breathability, the membrane 6 at 25 ° C and at a thickness of 50 microns high water vapor permeability of at least 12.5 1 / m 2 per 24 h, in particular at least 17.5 1 / m 2 per 24 h, preferably at least 20 l / m 2 per 24 h or more (measured according to the "inverted cup method" according to ASTM E 96 and at 25 ° C.) (For further details on the measurement the water vapor permeability [water vapor transmission, WVT], see also McCullough et al. "A comparison of standard methods for measuring water vapor permeability of fabrics" in Meas. Sci. Technol. [Measurements Science and Technology] 14, 1402-1408, August 2003 ). This ensures a particularly high wearing comfort.

Aufgrund der Vielzahl von Schichten 3, 4, 5, 6, 8 und 9 des Schichtaufbaus 2 ist die Wasserdampfdurchlässigkeit des Schutzhandschuhs 1 insgesamt - im Vergleich zu der Membran 6 allein - geringfügig geringer; die Wasserdampfdurchlässigkeit des Schutzhandschuhs 1 insgesamt ist dennoch sehr hoch und beträgt mindestens 101 / m2 pro 24 h, insbesondere mindestens 15 1 / m2 pro 24 h, vorzugsweise mindestens 201 / m2 pro 24 h, bei einer Dicke der Membran 6 von 50 µm (bei 25 °C).Due to the large number of layers 3, 4, 5, 6, 8 and 9 of the layer structure 2, the water vapor permeability of the protective glove 1 as a whole is slightly lower compared to the membrane 6 alone; the water vapor permeability of the protective glove 1 overall is still very high and is at least 101 / m 2 per 24 h, in particular at least 15 1 / m 2 per 24 h, preferably at least 201 / m 2 per 24 h, with a thickness of the membrane 6 of 50 μm (at 25 ° C).

Die Membran 6 sollte aus Gründen der Atmungsaktivität einen geringen Wasserdampfdurchgangswiderstand Ret unter stationären Bedingungen - gemessen nach DIN EN 31 092:1993 vom Februar 1994 ("Textilien - Physiologische Wirkungen, Messung des Wärme- und Wasserdampfdurchgangswiderstandes unter stationären Bedingungen [sweating guarded-hotplate test]") bzw. nach gleichlautender internationaler Norm ISO 11 092 - bei 35 °C von höchstens 30 (m2 · Pascal) / Watt, insbesondere höchstens 25 (m2· Pascal) / Watt, vorzugsweise höchstens 20 (m2 · Pascal) / Watt, bei einer Dicke der Membran 6 von 50 µm aufweisen. Aufgrund der Vielzahl von Schichten 3, 4, 5, 6, 8 und 9 des Schichtaufbaus 2 ist der Wasserdampfdurchgangswiderstand Ret des Schutzhandschuhs 1 insgesamt - im Vergleich zu der Membran 6 allein - geringfügig höher; im allgemeinen beträgt der Wasserdampfdurchgangswiderstand Ret des Handschuhs 1 insgesamt höchstens 30 (m2 · Pascal) / Watt, insbesondere höchstens 25 (m2 Pascal) / Watt, vorzugsweise höchstens 20 (m2 · Pascal) / Watt, bei einer Dicke der Membran 6 von 50 µm.The membrane 6 was for reasons of breathability a low water vapor transmission resistance R et under stationary conditions - measured according to DIN EN 31 092: 1993 of February 1994 ("Textiles - Physiological effects, measurement of heat and water vapor transmission resistance under steady state conditions [sweating guarded-hotplate test ] ") or according to the same international standard ISO 11 092 - at 35 ° C of at most 30 (m 2 · Pascal) / watt, in particular at most 25 (m 2 · Pascal) / watt, preferably at most 20 (m 2 · Pascal) / Watt, have a thickness of the membrane 6 of 50 microns. Due to the large number of layers 3, 4, 5, 6, 8 and 9 of the layer structure 2, the water vapor transmission resistance R et of the protective glove 1 as a whole is slightly higher than that of the membrane 6 alone; In general, the water vapor transmission resistance R et of the glove 1 is at most 30 (m 2 · Pascal) / watt, in particular at most 25 (m 2 Pascal) / watt, preferably at most 20 (m 2 · Pascal) / watt, with a thickness of the membrane 6 of 50 μm.

Die Membran 6 sollte im übrigen allenfalls nur geringfügig wasseraufnahmefähig bzw. quellfähig sein; eine geringfügige Wasseraufnahmefähigkeit bzw. Quellfähigkeit erhöht den Tragekomfort. Insbesondere sollte die Quellfähigkeit bzw. das Wasseraufnahmevermögen der Membran 6 höchstens 35 %, insbesondere höchstens 25 %, vorzugsweise höchstens 20 %, bezogen auf das Eigengewicht der Membran 6, betragen. Im übrigen sollte die Membran 6 gegenüber Flüssigkeiten, insbesondere Wasser, und/oder gegenüber Aerosolen zumindest im wesentlichen undurchlässig sein oder zumindest deren Durchtritt verzögern. Zur Erreichung einer allenfalls geringfügigen Quellfähigkeit sollte die Membran 6 keine oder im wesentlichen keine stark hydrophilen Gruppen, insbesondere keine Hydroxylgruppen, aufweisen. Zu Zwecken einer geringfügigen Quellung kann die Membran 6 aber schwach hydrophile Gruppen, beispielsweise Polyethergruppen, aufweisen.Otherwise, the membrane 6 should at most only be able to absorb or swell water to a slight extent; a slight water absorption capacity or swelling capacity increases the wearing comfort. In particular, the swelling capacity or the water absorption capacity of the membrane 6 should be at most 35%, in particular at most 25%, preferably at most 20%, based on the intrinsic weight of the membrane 6. Moreover, the membrane 6 should be at least substantially impermeable to liquids, in particular water, and / or aerosols, or at least delay their passage. To achieve at most a slight swelling capacity, the membrane 6 should have no or substantially no strongly hydrophilic groups, in particular no hydroxyl groups. For the purposes of a slight swelling, the membrane 6 but weakly hydrophilic groups, such as polyether groups have.

Die Membran 6 kann aus einem Kunststoff oder einen Polymermaterial bestehen oder ein solches umfassen. Ein solcher Kunststoff bzw. ein solches Polymer kann geeigneterweise z. B. ausgewählt sein aus der Gruppe von Polyurethanen, Polyetheramiden, Polyesteramiden, Polytetrafluorethylenen und/oder Polymeren auf Cellulosebasis sowie Derivaten der vorgenannten Verbindungen. Beispielsweise kann die Membran 6 als Reaktionsprodukt aus der Reaktion eines Isocyanats, insbesondere eines maskierten oder blockierten Isocyanats, mit einem isocyanatreaktiven Vernetzer erhalten sein. So kann die Membran 6 beispielsweise eine polyurethanbasierte Membran sein. Gleichermaßen kann die Membran 6 auch eine expandierte, gegebenenfalls mikroporöse Membran auf Basis von Polytetrafluorethylen sein.The membrane 6 may consist of or comprise a plastic or a polymer material. Such a plastic or such a polymer may suitably z. B. be selected from the group of polyurethanes, polyetheramides, polyesteramides, polytetrafluoroethylenes and / or polymers based on cellulose and derivatives of the aforementioned compounds. For example, the membrane 6 can be obtained as a reaction product from the reaction of an isocyanate, in particular a masked or blocked isocyanate, with an isocyanate-reactive crosslinker. For example, the membrane 6 may be a polyurethane-based membrane. Similarly, the membrane 6 may also be an expanded, optionally microporous membrane based on polytetrafluoroethylene.

Gemäß einer besonderen Ausführungsform kann die gegebenenfalls vorhandene Membran 6 als ein mehrschichtiges Membranlaminat bzw. als ein mehrschichtiger Membranverbund ausgebildet sein. Dieses Membranlaminat bzw. dieser Membranverbund kann aus mindestens zwei, vorzugsweise mindestens drei miteinander verbundenen Membranschichten oder -lagen bestehen. Beispielsweise kann dieses Membranlaminat bzw. dieser Membranverbund eine Kernschicht auf Basis eines Polymers auf Cellulosegrundlage und zwei mit der Kernschicht verbundene äußere Schichten, insbesondere auf Basis eines Polyurethans, eines Polyetheramids und/oder eines Polyesteramids, umfassen. Dabei kann die Kernschicht auf Basis eines Polymers auf Cellulosegrundlage als 1 bis 100 µm, insbesondere 5 bis 50 µm, vorzugsweise 10 bis 20 µm dicke Membran ausgebildet sein und können die zwei mit der Kernschicht verbundenen äußeren Schichten jeweils als 1 bis 100 µm, insbesondere 5 bis 50 µm, vorzugsweise 5 bis 10 µm dicke Membran ausgebildet sein. Diese besondere Ausgestaltung der Membran 6 ermöglicht es, verschiedene Membranmaterialien mit jeweils unterschiedlichen Eigenschaften, insbesondere unterschiedlichen Wasserdampfdurchlässigkeiten und/oder Baniefewirkungen gegenüber chemischen Giften, miteinander zu kombinieren und so eine Optimierung der Eigenschaften der Membran 6 zu erreichen. Beispielsweise sind Cellulose und Cellulosederivate ausgezeichnete Sperrschichtmaterialien, insbesondere gegenüber chemischen Schad- bzw. Giftstoffen, wie z. B. Kampfstoffen (Lost etc.), und werden von diesen Giften nicht angegriffen bzw. aufgelöst; zum anderen verhindern polyurethanbasierte Materialien eine Migration bzw. Diffusion der in der Celluloseschicht gegebenenfalls vorhandenen Weichmacher und dämpfen außerdem das durch die Cellulose bedingte, beim Tragen auftretende Knistern. Deswegen ist es gemäß dieser besonderen Ausführungsform bevorzugt, daß im Fall eines Membranlaminats oder -verbunds die Kernschicht auf Basis eines Polymers auf Cellulosegrundlage gebildet wird, während die beiden Außenschichten der Membran 6 durch Polyurethanschichten gebildet werden.According to a particular embodiment, the optionally present membrane 6 may be formed as a multilayer membrane laminate or as a multilayer membrane composite. This membrane laminate or membrane composite can consist of at least two, preferably at least three interconnected membrane layers or layers. By way of example, this membrane laminate or membrane composite may comprise a core layer based on a cellulose-based polymer and two outer layers bonded to the core layer, in particular based on a polyurethane, a polyetheramide and / or a polyesteramide. The core layer based on a cellulose-based polymer may be formed as a 1 to 100 μm, in particular 5 to 50 μm, preferably 10 to 20 μm thick membrane and the two outer layers connected to the core layer may each be 1 to 100 μm, in particular 5 be formed to 50 microns, preferably 5 to 10 microns thick membrane. This particular embodiment of the membrane 6 makes it possible to combine different membrane materials, each with different properties, in particular different water vapor permeabilities and / or Baniefewirkung compared to chemical poisons, and thus to achieve an optimization of the properties of the membrane 6. For example, cellulose and cellulose derivatives are excellent barrier materials, especially against chemical pollutants or toxins such. B. warfare agents (Lost etc.), and are not attacked or dissolved by these poisons; on the other hand polyurethane-based materials prevent migration or diffusion of the softeners optionally present in the cellulosic layer and also attenuate the cellulose-related, crackling occurring during the application. Therefore, according to this particular embodiment, it is preferred that, in the case of a membrane laminate or composite, the core layer be based on a cellulose-based polymer, while the two outer layers of the membrane 6 are formed by polyurethane layers.

Wie zuvor geschildert, kann - insbesondere um die Stabilität bzw. Verschließbeständigkeit, insbesondere die Reißfestigkeit, der Membran 6 im Herstellungsprozeß (z. B. beim Bedrucken der Membran 6 mit heißem Klebstoff 7) wie auch beim Tragen zu erhöhen - die Membran 6 auf einer zusätzlichen Trägerschicht 8 aufgebracht bzw. aufkaschiert sein. Diesbezüglich kann auf obige Ausführungen verwiesen werden.As described above, in particular in order to increase the stability or sealing resistance, in particular the tear strength, of the membrane 6 in the production process (eg when printing on the membrane 6 with hot adhesive 7) as well as when wearing it, the membrane 6 can be mounted on one be applied or laminated on additional carrier layer 8. In this regard, reference may be made to the above statements.

Zur Erhöhung des Tragekomforts einerseits und zur Erzielung einer guten Verschleißbeständigkeit andererseits ist es vorteilhaft, wenn die Membran 6 eine gewisse Elastizität aufweist. Insbesondere ist es vorteilhaft, wenn die Membran 6 zu mindestens 10 %, insbesondere zu mindestens 20 %, vorzugsweise zu mindestens 30 % oder mehr, zumindest in eine Richtung gedehnt bzw. gestreckt werden kann (bezogen auf die Membran 6). Auch der Schichtaufbau 2 insgesamt sollte zu den vorgenannten Zwecken - neben einer guten Biegsamkeit - auch eine gewisse Elastizität aufweisen; verglichen mit der Membran 6, ist die Elastizität des Schichtaufbaus 2 als Ganzes jedoch etwas geringer, und im allgemeinen ist der Schichtaufbau 2 insgesamt zu mindestens 5 %, vorzugsweise zu mindestens 10 %, ganz besonders bevorzugt zu mindestens 15 % oder mehr, zumindest in eine Richtung dehnbar bzw. streckbar.To increase the wearing comfort on the one hand and to achieve good wear resistance on the other hand, it is advantageous if the membrane 6 has a certain elasticity. In particular, it is advantageous if the membrane 6 can be stretched or stretched to at least 10%, in particular to at least 20%, preferably to at least 30% or more, at least in one direction (based on the membrane 6). The layer structure 2 as a whole should for the aforementioned purposes - in addition to a good flexibility - also have a certain elasticity; However, compared to the membrane 6, the elasticity of the layer structure 2 as a whole is slightly lower, and generally the layer structure 2 is at least 5%, preferably at least 10%, more preferably at least 15% or more, at least one Direction stretchable or stretchable.

Gemäß einer besonderen, in den Figuren nicht dargestellten Ausführungsform kann die Membran 6 gleichzeitig die Klebstoffschicht 7 zur Befestigung der Adsorptionsschicht 5 darstellen. In diesem Fall muß die Membran 6 selbstklebend, insbesondere hitzeklebrig, ausgebildet sein. Gemäß dieser besonderen Ausführungsform kommt es zu einer Einsparung von Gewicht, da auf eine zusätzliche Klebstoffschicht 7 gänzlich verzichtet werden kann.According to a particular, not shown in the figures embodiment, the membrane 6 can simultaneously represent the adhesive layer 7 for fixing the adsorption layer 5. In this case, the membrane 6 must be self-adhesive, in particular heat-tacky, formed. According to this particular embodiment, there is a saving in weight, as can be dispensed with an additional adhesive layer 7 entirely.

Bei dem Aufbau bzw. der Konzeption des erfindungsgemäßen Schutzhandschuhs 1 geht man im allgemeinen derart vor, daß die Membran 6 des Schutzhandschuhs 1 aus zwei miteinander verbundenen, vorzugsweise abdichtend miteinander verbundenen, insbesondere miteinander verklebten und/oder verschweißten Materialstücken besteht. Dabei weisen beide Materialstücke jeweils die Form einer Hand mit fünf Fingern auf, wobei eines der beiden Materialstücke zur Abdeckung der Handvorderseite (Handinnenseite) und das andere Materialstück zur Bedeckung der Andrückseite (Handrücken) bestimmt ist und die beiden Materialstücke nur entlang ihrer jeweiligen äußeren Konturen, insbesondere entlang des Handumrisses, miteinander verbunden, vorzugsweise abdichtend miteinander verbunden, insbesondere miteinander verklebt und/oder verschweißt, sind.In the design of the protective glove 1 according to the invention is generally carried out in such a way that the membrane 6 of the protective glove 1 consists of two interconnected, preferably sealingly interconnected, in particular glued together and / or welded pieces of material. In this case, both pieces of material each have the shape of a hand with five fingers, one of the two pieces of material for covering the front of the hand (hand inside) and the other piece of material for covering the Andrückseite (back of the hand) is determined and the two pieces of material only along their respective outer contours, in particular along the outline of the hand, connected to each other, preferably sealingly connected to each other, in particular glued together and / or welded, are.

Was die Adsorptionsschicht 5 des erfindungsgemäßen Schutzhandschuhs 1 anbelangt, so ist diese im allgemeinen diskontinuierlich ausgebildet, d. h. die A.dsorptionsschicht 5 umfaßt im allgemeinen diskrete, chemische Gifte adsorbierende Adsorpdonspartikel (z. B. auf Basis von Aktivkohle), die beispielsweise mittels eines Klebstoffs 7 auf der Membran 6 fixiert sein können. Das Adsorptionsmaterial der Adsorptionsschicht 5 ist insbesondere ein Aktivkohle enthaltendes oder hieraus bestehendes Adsorptionsmaterial, beispielsweise ein Material auf Basis von Aktivkohle in Form von Aktivkohleteilchen und/oder Aktivkohlefasern.As regards the adsorption layer 5 of the protective glove 1 according to the invention, this is generally discontinuous, d. H. the A.dsorptionsschicht 5 generally comprises discrete, adsorbent adsorbent chemical particles (eg based on activated carbon), which may be fixed for example by means of an adhesive 7 on the membrane 6. The adsorption material of the adsorption layer 5 is in particular an adsorbent material containing or consisting of activated carbon, for example a material based on activated carbon in the form of activated carbon particles and / or activated carbon fibers.

Denn, wenn als Adsorptionsmaterial für die Ausbildung der Adsorptionsschicht 5 aktivkohlehaltige Materialien verwendet werden, kann der ohnehin bestehende, hohe Tragekomfort noch weiter gesteigert werden, weil die Aktivkohle als intermediärer Feuchtigkeits- bzw. Wasserspeicher (z. B. für Schweiß) dient und Feuchtigkeit bzw. Wasser sozusagen "abpuffern" kann. Bei Verwendung beispielsweise von Aktivkohlekügelchen als Adsorptionsmaterial für die Adsarptionssehicht 5 sind Auflagen von bis zu ca. 250 g / m2 oder mehr üblich, so daß z. B. bei einem Schweißausbruch etwa 40 g / m2 Feuchtigkeit gespeichert werden können, die im Fall einer atmungsaktiven Träger- bzw. Außenschicht 3 dann wieder an die Umgebung abgegeben werden können.For if activated carbon-containing materials are used as adsorption material for the formation of the adsorption layer 5, the already existing high wearing comfort can be further increased because the activated carbon serves as an intermediate moisture or water reservoir (eg for sweat) and moisture or moisture Water can, so to speak, "buffer" it. When using, for example, activated carbon beads as adsorption material for the Adsarptionssehicht 5 runs of up to about 250 g / m 2 or more are common, so that z. B. in a sweat break about 40 g / m 2 moisture can be stored, which can then be given back to the environment in the case of a breathable carrier or outer layer 3.

Gemäß einer Ausführungsform der vorliegenden Erfindung umfaßt die Adsorptionsschicht 5 diskrete Aktivkohleteilchen, vorzugsweise in Konform ("Komkohle") oder ("Kugelkohle"), In diesem Fall beträgt der mittlere Durchmesser der Aktivkohleteilchen weniger als 1,0 mm, insbesondere weniger als 0,5 mm, vorzugsweise weniger als 0,4 mm, bevorzugt weniger als 0,35 mm; der mittlere Durchmesser der Aktivkohleteilchen beträgt jedoch mindestens 0,1 mm. Bei dieser Ausführungsform werden die Aktivkohleteilchen im allgemeinen in einer Menge von 5 bis 500 g/m2, vorzugsweise 20 bis 300 g/m2, bevorzugt 25 bis 250 g/m2, besonders bevorzugt 50 bis 120 g/m2, auf der Membran 6 aufgebracht. Geeignete Aktivkohleteilchen weisen innere Oberflächen (BET) von mindestens 800 m2/ g, insbesondere von mindestens 900 m2/ g, vorzugsweise von mindestens 1.000 m2/ g, bevorzugt im Bereich von 800 bis 1.500 m2/ g, auf. Kornkohle, insbesondere Kugelkohle, hat den entscheidenden Vorteil, daß sie enorm abriebfest und sehr hart ist, was in bezug auf die Verschleißeigenschaften von großer Bedeutung ist. Bevorzugterweise beträgt der Berstdruck für ein einzelnes Aktivkohleteilchen, insbesondere Aktivkohlekörnchen bzw. -kügelchen, im allgemeinen mindestens etwa 5 Newton, insbesondere mindestens etwa 10 Newton, und kann bis zu etwa 20 Newton erreichen.According to one embodiment of the present invention, the adsorbent layer 5 comprises discrete particles of activated carbon, preferably in conformance ("charcoal") or ("carbon spheres"). In this case, the average diameter of the activated carbon particles is less than 1.0 mm, in particular less than 0.5 mm, preferably less than 0.4 mm, preferably less than 0.35 mm; however, the average diameter of the activated carbon particles is at least 0.1 mm. In this embodiment, the activated carbon particles are generally in an amount of 5 to 500 g / m 2 , preferably 20 to 300 g / m 2 , preferably 25 to 250 g / m 2 , particularly preferably 50 to 120 g / m 2 , on the Membrane 6 applied. Suitable activated carbon particles have internal surface areas (BET) of at least 800 m 2 / g, in particular of at least 900 m 2 / g, preferably of at least 1000 m 2 / g, preferably in the range of 800 to 1500 m 2 / g. Grain, especially ball carbon, has the distinct advantage that it is extremely abrasion resistant and very hard, which is of great importance in terms of wear properties. Preferably, the bursting pressure for a single particle of activated carbon, especially activated carbon granules, is generally at least about 5 Newton, more preferably at least about 10 Newton, and may reach up to about 20 Newton.

Gemäß einer alternativen Ausführungsform kann die Adsorptionsschicht 5 als Adsorptionsmaterial Aktivkohlefasern, insbesondere in Form von Aktivkohlefaserflächengebilden, umfassen. Derartige Aktivkohlefaserflächengebilde können beispielsweise ein Flächengewicht von 20 bis 200 g/m2, insbesondere 30 bis 150 g/m2, vorzugsweise 15 bis 120 g/m2, aufweisen. Bei diesen Aktivkohlefaserflächengebilden kann es sich beispielsweise um Aktivkohlefasergewebe, -gewirke, -gelege oder -verbundstoffe handeln (z. B auf Basis von carbonisierter und aktivierter Cellulose und/oder carbonisierten und aktivierten Acrylnitrilen).According to an alternative embodiment, the adsorption layer 5 as adsorption material comprise activated carbon fibers, in particular in the form of activated carbon fiber sheets. Such activated carbon fiber sheetings may, for example, have a weight per unit area of 20 to 200 g / m 2 , in particular 30 to 150 g / m 2 , preferably 15 to 120 g / m 2 . These activated carbon fiber sheets may be, for example, activated carbon fiber fabrics, knits, blends or composites (eg, based on carbonized and activated cellulose and / or carbonized and activated acrylonitriles).

Gleichermaßen ist es auch möglich, als Adsorptionsmaterial der Adsorptionsschicht 5 Aktivkahleteilchen und Aktivkohlefasern miteinander zu kombinieren. Aktivkahleteilchen haben den Vorteil einer höheren Adsorptionskapazität, während Aktivkohlefasern eine bessere Adsorptionskinetik aufweisen.Likewise, it is also possible to combine 5 adsorbent material of the adsorption layer Aktivkahleteilchen and activated carbon fibers with each other. Active carbon particles have the advantage of higher adsorption capacity, while activated carbon fibers have better adsorption kinetics.

Zur Erhöhung der Adsorptionseffizienz bzw. Adsorptionsleistung besteht die Möglichkeit, das Adsorptionsmaterial der Adsorptionsschicht 5, insbesondere die Aktivkohleteilchen und/oder die Aktivkohlefasern, außerdem mit mindestens einem Katalysator zu imprägnieren.
