Description

Die Erfindung betrifft eine Unterbeinschutzbekleidung, insbesondere Schutzsocken, gegen chemische und/oder biologische Schadstoffe.The invention relates to a lower leg protective clothing, in particular protective socks, against chemical and / or biological contaminants.

Bekannt sind Unterbeinschutzbekleidungen auf zivilem Gebiet, insbesondere medizinischem Gebiet. So ist z.B. in der EP 0 705 543 B1 eine Unterbeinschutzbekleidung beschrieben, die zur Vermeidung einer Verletzung oder eines Wiederauftretens einer Verletzung bei Sport- oder Trainingsaktivitäten eine Bandagenwirkung ergeben soll.Known underarm protection garments in civil areas, especially medical field. For example, in the EP 0 705 543 B1 a lower leg protective clothing is described, which is to avoid bandage effect to avoid injury or recurrence of injury in sports or training activities.

Bekannt sind auch wasserdichte, atmungsfähige Socken (siehe z.B. EP 0 386 144 B1 ).Also known are waterproof, breathable socks (see, eg EP 0 386 144 B1 ).

Die DE 199 18 425 A1 beschreibt einen Schutzschuh, in welchem ein Innenschuh mit einer atmungsaktiven Membran als Strumpf ausgebildet ist.The DE 199 18 425 A1 describes a protective shoe in which an inner shoe with a breathable membrane is designed as a stocking.

Die EP 1 269 877 beschreibt einen Schutzanzug als Overall zum Schutz gegen chemische Schadstoffe.The EP 1 269 877 describes a protective suit as overalls for protection against chemical pollutants.

Eine weitere Unterbeinschutzbekleidung wird in der US-2003/177566 offenbart.Another lower leg protective clothing is used in the US 2003/177566 disclosed.

Nachteilig bei bekannten Schutzanzügen gegen chemische und/oder biologische Schadstoffe auf militärischem Gebiet ist, dass diese nur bis zum Knöchel reichen und die Füße somit nicht geschützt sind. Zum Schutz der Füße werden Überziehstiefel aus 100 % Butyl genutzt.A disadvantage of known protective suits against chemical and / or biological contaminants in the military field is that they extend only to the ankle and thus the feet are not protected. To protect the feet, overboots made of 100% butyl are used.

Nachteilig dabei ist jedoch, dass die Stiefel erst angezogen werden können, wenn der Soldat den Schutzanzug angezogen hat. Da aber die Schutzanzüge meist sehr steif sind, ist das Anziehen der Überziehstiefel relativ beschwerlich. Die bekannten Überziehstiefel besitzen auch keine Atmungsaktivität und sind relativ unförmig und groß. Dadurch, dass sie von den Schutzanzügen separat sind, besteht auch die Gefahr, dass sie verloren werden.The disadvantage here is that the boots can only be tightened when the soldier has put on the suit. But since the protective suits are usually very stiff, putting on the overboot is relatively cumbersome. The known pull-on boots also have no breathability and are relatively bulky and large. The fact that they are separate from the protective suits, there is also a risk that they will be lost.

Der vorliegenden Erfindung liegt daher die Aufgabe zugrunde, eine Unterbeinschutzbekleidung, insbesondere einen Schutzsocken zu schaffen, der die vorstehend genannten Nachteile vermeidet, insbesondere der einen hohen Tragekomfort bietet und wie ein herkömmlicher Socken oder Strumpf getragen werden kann.The present invention is therefore an object of the invention to provide a Unterbeinschutzbekleidung, in particular a protective socks, which avoids the disadvantages mentioned above, in particular, which offers a high level of comfort and how a conventional socks or stockings can be worn.

Erfindungsgemäß wird diese Aufgabe gelöst durch eine Unterbeinschutzbekleidung, insbesondere einem Schutzsocken, der mehrere Lagen aufweist, mit einem Außenbeinteil und einem im Inneren des Außenbeinteiles angeordneten Laminat, das eine die Außenseite des Laminats bildende flexible, winddichte und wasserabweichende Membran, die wenigstens eine Barriere für biologische Schadstoffe bildet, eine unter der Membran angeordnete Kohlenstoffschicht, in der Kohlenstoff in Faser- oder Partikelform vorhanden ist, und eine innere textile Stofflage aufweist.According to the invention this object is achieved by a Unterbeinschutzbekleidung, in particular a protective socks, which has a plurality of layers, with an outer leg part and a arranged inside the outer leg part laminate, forming the outside of the laminate flexible, windproof and water-repellent membrane, the at least one barrier for biological Contaminants forms, a disposed below the membrane carbon layer in which carbon is present in fiber or particle form, and having an inner textile fabric layer.

Die erfindungsgemäße Unterbeinschutzbekleidung bietet neben einem Schutz gegen chemische und/oder biologische Schadstoffe auch einen hohen Tragekomfort. Sie ist sehr flexibel und lässt sich wie ein "normaler" Strumpf oder Socken tragen. Insbesondere kann man die erfindungsgemäße Unterbeinschutzbekleidung anziehen, bevor der Anzug angezogen wird, womit im Einsatzfall eine einen Schutzanzug tragende Person schneller angezogen ist und darüber hinaus auch eine bessere Bewegungsfreiheit besitzt.The lower leg protection clothing according to the invention offers protection against chemical and / or biological pollutants as well as a high wearing comfort. She is very flexible and can be worn like a "normal" stocking or socks. In particular, one can the lower leg protective clothing according to the invention Wear before the suit is tightened, which in the case of use a person wearing a protective suit is attracted faster and also has better freedom of movement.

Falls die Membran erfindungsgemäß atmungsaktiv ausgebildet ist, so lässt sich der Tragekomfort noch stärker verbessern.If the membrane according to the invention is designed to be breathable, the wearing comfort can be improved even more.

Das äußere Beinteil kann bei einer Ausbildung als Socken einen Außensocken aus Wolle, Baumwolle, Seide, Polyester, Polypropylen, Polyamid, Polyacryl, Modifikationen oder Mischungen daraus bestehen. Durch das erfindungsgemäße Laminat wird ein Schutz gegen chemische und/oder biologische Schadstoffe erreicht. So verhindert die Winddichtheit der Membran, dass Wind in die darunter liegende Kohlenstoffschicht eintritt und damit dessen Wirksamkeit beeinträchtigt. Aufgrund der Wasserdichtheit wird gleichzeitig auch ein Durchnässen oder ein Eindringen von flüssigen Chemikalien in die Kohlenstoffschicht verhindert, was ebenfalls zu einer Wirksamkeitsbeeinträchtigung führen würde.The outer leg part, when formed as socks, may consist of an outer sock made of wool, cotton, silk, polyester, polypropylene, polyamide, polyacrylic, modifications or blends thereof. The laminate according to the invention provides protection against chemical and / or biological pollutants. Thus, the wind-tightness of the membrane prevents wind from entering the underlying carbon layer, thereby impairing its effectiveness. Due to the water-tightness at the same time also a wetting or penetration of liquid chemicals is prevented in the carbon layer, which would also lead to a deterioration of effectiveness.

Neben einer Wirkung als Barriere gegen biologische Schadstoffe wirkt die Membran bei einer entsprechenden Ausgestaltung auch als Filter gegen Schadstoffe.In addition to acting as a barrier against biological contaminants, the membrane also acts as a filter against pollutants in a corresponding embodiment.

Bei einem Eindringen von flüssigen Schadstoffen verteilen sich diese in der Membran und werden im allgemeinen abgeblockt. Soweit sie nicht abgeblockt werden - diffundieren sie so langsam durch, dass sie in einem Aggregatzustand an der Kohlenstoffschicht ankommen, bei der diese wirksam ist. Durch diesen Mechanismus wird die Anzahl Chemikalien, gegen die eine Schutzwirkung erzielt wird, stark erhöht. Versuche in der Praxis haben gezeigt, dass das erfindungsgemäße Laminat eine deutlich bessere und vor allen Dingen längere Schutzwirkung als bekannte Materialien besitzt.When liquid pollutants enter, they spread in the membrane and are generally blocked off. Unless they are blocked, they diffuse so slowly that they arrive in an aggregate state at the carbon layer where it is effective. By this mechanism, the number of chemicals against which a protective effect is achieved, greatly increased. tries In practice, it has been shown that the laminate according to the invention has a significantly better and, above all, longer protective effect than known materials.

Bei Verwendung von hydrophilen Membranen, wie z.B. Polyester, Polyether, Polyester-Copolymer und ähnlichem, liegt keine Mikroporösität vor, wodurch eine Barriere gegen biologische Schadstoffe gegeben ist. Wasserdampfmoleküle können jedoch trotzdem hindurchtreten, Wasser hingegen nicht.When using hydrophilic membranes, e.g. Polyester, polyether, polyester copolymer and the like, there is no microporosity, whereby a barrier against biological pollutants is given. Nevertheless, water vapor molecules can pass through, but water does not.

Da durch die vorgeschaltete Membran bereits eine Schutzwirkung erreicht wird, kann die darunter liegende Kohlenstoffschicht ohne eine Beeinträchtigung ihrer Wirksamkeit dünner ausgebildet werden. Der Tragekomfort wird dadurch erheblich erhöht, weil die hitzestauende Kohlenstoffschicht dünner ist.Since a protective effect is already achieved by the upstream membrane, the underlying carbon layer can be made thinner without compromising their effectiveness. The wearing comfort is considerably increased because the heat-accumulating carbon layer is thinner.

Weitere vorteilhafte Materialien für die Membran sind z.B. auf Cellophan basierende Materialien, Polyvinylalkohol, Polyacrylamide, Polyurethane und Mischungen daraus.Further advantageous materials for the membrane are e.g. cellophane-based materials, polyvinyl alcohol, polyacrylamides, polyurethanes, and mixtures thereof.

Bei Verwendung von mikroporösen Membranen, wie z.B. Polytetrafluorethylen, wird trotz Winddichtheit und einer Wasserdichtheit eine Atmungsaktivität erreicht.When using microporous membranes, e.g. Polytetrafluoroethylene, despite windproofness and waterproofness breathability is achieved.

Erfindungsgemäß ist dabei von Vorteil, wenn eine derart kleine Porengröße gewählt wird, dass lediglich Wasserdampf durch die kleinen Poren hindurchtritt. Da biologische Schadstoffe im allgemeinen größer sind, werden diese auf diese Weise an einem Durchdringen gehindert.According to the invention, it is advantageous if such a small pore size is selected that only water vapor passes through the small pores. Since biological contaminants are generally larger, they are prevented from penetrating in this way.

Die Kohlenstoffschicht kann aus einem Gewebe oder Gewirk mit 100 % aktivierten Fasern oder auch Aktivkohlekügelchen aufweisen, die auf ein Trägermaterial aufgetragen wurden.The carbon layer may comprise a woven or knitted fabric having 100% activated fibers or also activated carbon beads applied to a substrate.

Der Tragekomfort wird noch deutlicher verbessert, wenn zusätzlich zu dem Außenbeinteil noch ein Innenbeinteil auf der Innenseite, d.h. der dem Träger zugewandten Seite, des Laminates angeordnet ist. Das Innenbeinteil kann bei einer Ausbildung als Innensocken aus Chemiefasern hergestellt sein, wie z.B. Polypropylen, Polyamid, Polyester, Modifikationen und Mischungen daraus.Carrying comfort is even more improved if, in addition to the outer leg part, there is still an inner leg part on the inside, i. the side facing the carrier, the laminate is arranged. The inner leg part, when formed as inner socks, may be made of man-made fibers, e.g. Polypropylene, polyamide, polyester, modifications and blends thereof.

Als textile Stofflage kann ein textiles Gewebe vorgesehen sein, das eine mechanische Schutzschicht für die Kohlenstoffschicht bildet. Außenseitig bildet die Membran neben ihrer Schutzwirkung gegen Schadstoffe ebenfalls eine mechanische Schutzschicht für die Faserschicht.As textile fabric layer, a textile fabric may be provided which forms a mechanical protective layer for the carbon layer. On the outside, the membrane also forms a mechanical protective layer for the fiber layer in addition to its protective effect against pollutants.

Die erfindungsgemäße Unterbeinschutzbekleidung wird nachfolgend anhand eines Schutzsockens beschrieben. Selbstverständlich sind jedoch auch noch andere Unterbeinschutzbekleidungen, wie z.B. Strümpfe, in der erfindungsgemäßen Ausgestaltung möglich.The lower leg protective clothing according to the invention is described below on the basis of a protective sock. Of course, however, other lower leg protection garments, such as e.g. Stockings, in the embodiment of the invention possible.

Der in den Figuren 1 und 2 dargestellte Schutzsocken weist als Außenbeinteil einen Außensocken 1 auf. Im Inneren des Außensockens 1 ist ein Laminat 2 angeordnet, dessen Aufbau nachfolgend anhand der Figuren 6 und 7 näher beschrieben wird. Innenseitig ist als Abschluss des Schutzsockens als Innenbeinteil ein Innensocken 3 angeordnet.The in the Figures 1 and 2 Protective socks shown has as outer leg part on an outer sock 1. Inside the outer cam 1, a laminate 2 is arranged, whose structure is described below with reference to FIG FIGS. 6 and 7 will be described in more detail. On the inside, an inner sock 3 is arranged as an end of the protective sock as inner leg part.

Die drei Lagen, bestehend aus Außensocken 1, Laminat 2 und Innensocken 3, sind miteinander verbunden und werden als ein Schutzsocken gemeinsam angezogen. Die Verbindung zwischen den drei Lagen kann z.B. durch Nähen und/oder Verkleben erfolgen. Die Vernähung kann z.B. im Bereich der oberen Enden der drei Lagen und zusätzlich noch im Fersen- und Fußspitzenbereich, z.B. mittels Fahnen, erfolgen.The three layers, consisting of outer socks 1, 2 laminate and inner socks 3, are connected together and are tightened together as a protective socks. The connection between the three layers may e.g. done by sewing and / or gluing. The suturing may e.g. in the area of the upper ends of the three layers and additionally in the heel and toe area, e.g. by means of flags.

Der Innensocken 3 kann gegebenenfalls hydrophil ausgebildet sein. An den Nahtstellen sollte der Innensocken 3 aus weichem, flauschigem gesponnenem Garn gestrickt sein, damit Druckstellen am Fuß verhindert werden.The inner sock 3 may optionally be made hydrophilic. At the seams, the inner sock 3 should be made of soft, be knit fluffy spun yarn so that pressure marks on the foot are prevented.

Wenn der Innensocken 3 länger ausgebildet ist als das Laminat 2 und der Außensocken 1, kann man den Innensocken 3 am oberen Ende über das Laminat 2 und den Außensocken 1 in Form eines Bündchens nach außen stülpen, wie dies in den Figuren 1 und 2 gestrichelt dargestellt ist. Bei einem hydrophilen Innensocken 3 lässt sich auf diese Weise aufgesaugte Feuchtigkeit nach außen transportieren und kann dort verdunsten.If the inner sock 3 is formed longer than the laminate 2 and the outer sock 1, one can put the inner sock 3 at the upper end over the laminate 2 and the outer sock 1 in the form of a cuff to the outside, as shown in the Figures 1 and 2 is shown in dashed lines. In the case of a hydrophilic inner sock 3, moisture absorbed in this way can be transported outward and can evaporate there.

Außensocken 1 und Innensocken 2 können aus mehreren Schnittteilen gefertigt sein. Selbstverständlich können Außensocken 1 und Innensocken 3 auch ohne Naht gewebt oder gewirkt werden. Das Laminat 2 kann aus drei Schnittteilen hergestellt werden, wie dies aus den Figuren 3 bis 5 ersichtlich ist. Fig. 3 zeigt das Schnittteil für einen Schaft 4 des Laminats. Fig. 4 zeigt das Schnittteil für ein Fußoberteil 5 und Fig. 5 zeigt ein Schnittteil für eine Sohle 6 des Laminats. Gleiches oder ähnliches gilt für den Außensocken 1, wenn dieser ebenfalls aus Schnittteilen gefertigt ist.Outer socks 1 and inner socks 2 can be made of several cut parts. Of course, outer socks 1 and 3 inner socks can be woven or knitted without seam. The laminate 2 may be made of three cut pieces as shown in FIGS FIGS. 3 to 5 is apparent. Fig. 3 shows the cut part for a shaft 4 of the laminate. Fig. 4 shows the section for a Fußobererteil 5 and Fig. 5 shows a section for a sole 6 of the laminate. The same or similar applies to the outer cam 1, if this is also made of cut parts.

Die drei Schnittteile können mittels eines Flatlock-Stiches oder Zickzackstiches zusammengefügt werden, wobei die Nähte mit einem wasserdichten Material abgedichtet werden. Das wasserdichte Material kann z.B. aus einem wasserdichten Nahtabdichtungsband bestehen. Ebenso ist auch eine Verbindung der drei Schnittteile durch wasser- und gasdichte Kleber möglich, die ebenfalls eine Barriere gegen Schadstoffe bilden sollten.The three cut pieces can be joined together using a flatlock stitch or zigzag stitch, sealing the seams with a waterproof material. The waterproof material may for example consist of a waterproof seam sealing tape. Likewise, a connection of the three cutting parts by water and gas-tight adhesive is possible, which should also form a barrier against pollutants.

Die Fig. 6 zeigt in einem stark vergrößerten Querschnitt den Aufbau des Schutzsockens aus den drei Lagen, nämlich dem Außensocken 1, dem Laminat 2 und dem Innensocken 3. Aus der Fig. 6 ist weiterhin auch der Aufbau des Laminates 2, welches aus drei Schichten besteht, ersichtlich. Die äußere, d.h. von dem Träger abgewandten Seite des Laminates 2, wird durch eine Membran 7 gebildet. Unter der Membran 7, d.h. auf der dem Träger zugewandten Seite, befindet sich eine Kohlenstoffschicht 8 und als innere Schicht ist eine textile Stofflage 9 vorgesehen.The Fig. 6 shows in a greatly enlarged cross section the structure of the protective cam of the three layers, namely the outer sock 1, the laminate 2 and the inner socks 3. From the Fig. 6 is also the structure of the laminate 2, which consists of three layers, can be seen. The outer side, ie the side of the laminate 2 facing away from the carrier, is formed by a membrane 7. Below the membrane 7, ie on the side facing the wearer, there is a carbon layer 8 and as inner layer a textile fabric layer 9 is provided.

Die Membran 7, die Kohlenstoffschicht 8 und die textile Stofflage 9 werden in bekannter Weise durch ein Laminierungsverfahren miteinander zu einer Einheit verbunden. Dies kann z.B. durch eine Punkt-für-Punkt-Laminierung erfolgen, wobei Klebstoff punktweise zwischen die miteinander zu verbindenden Schichten eingebracht wird und dann während eines Durchlaufes durch Druckwalzen die Schichten miteinander verbunden werden. Das Laminierungsverfahren kann dabei mit oder ohne Erwärmung durchgeführt werden.The membrane 7, the carbon layer 8 and the textile fabric layer 9 are connected to one another in a known manner by a lamination process. This can e.g. by point-by-point lamination, wherein adhesive is introduced pointwise between the layers to be joined together and then the layers are bonded together during a pass through pressure rollers. The lamination process can be carried out with or without heating.

Die Fig. 7 zeigt grundsätzlich den gleichen Aufbau wie das Ausführungsbeispiel des Schutzsockens nach der Fig. 6. Der einzige Unterschied besteht darin, dass in diesem Fall der Innensocken 3 fehlt, so dass die textile Stofflage 9 des Laminates 2, die man in diesem Falle dann hydrophil ausbilden wird, am Fuß des Trägers anliegt. Die Membran 7 ist flexibel ausgestaltet, damit Dehnungen sowohl in Quer- als auch in Längsrichtung möglich sind und ein Reißen vermieden wird.The Fig. 7 shows basically the same structure as the embodiment of the protective cam according to the Fig. 6 , The only difference is that in this case the inner sock 3 is missing, so that the textile fabric layer 9 of the laminate 2, which in this case will then be made hydrophilic, bears against the foot of the wearer. The membrane 7 is designed to be flexible so that expansions in both the transverse and in the longitudinal direction are possible and tearing is avoided.

Wenn die Kohlenstoffschicht 8 als Gewebe ausgebildet ist, ergeben sich sehr gute Wascheigenschaften.If the carbon layer 8 is formed as a fabric, very good washing properties result.

Die aktive Kohlenstoffschicht 8 kann in Faserform aus einem Gestrick oder Gewebe hergestellt werden. Zur Herstellung von aktiven Kohlenstofffasern ist es bekannt, Viskosefasern bzw. ein Viskosegewebe oder -gestrick kontrolliert zu verbrennen und den Verbrennungsprozess dabei so zu steuern, dass Aktivkohle mit extrem feinen Poren gebildet wird, die dann die Filterwirkung erzeugen.The active carbon layer 8 can be made in fiber form from a knit or fabric. For the production of active carbon fibers, it is known to burn viscose fibers or a viscose fabric or knitted fabric in a controlled manner and to control the combustion process so that activated carbon with extremely fine pores is formed, which then produce the filter effect.

Die Dicke der Kohlenstoffschicht 8 kann zwischen 0,2 bis 1,0 mm, vorzugsweise zwischen 0,4 bis 0,8 mm, betragen.The thickness of the carbon layer 8 may be between 0.2 to 1.0 mm, preferably between 0.4 to 0.8 mm.

Vorteilhafte aktive Oberflächen der Kohlenstoffschicht 8 liegen in einem Bereich von 800 bis 2.000 m2/g, vorzugsweise zwischen 1.000 bis 1.200 m2/g.Advantageous active surfaces of the carbon layer 8 are in a range of 800 to 2,000 m 2 / g, preferably between 1,000 to 1,200 m 2 / g.
