Description

Unterbeinsc utzbekleidunq Lower leg protective clothing
Die Erfindung betrifft eine Unterbeinschutzbekleidung, insbesondere Schutzsocken, gegen chemische und/oder biologische Schadstoffe.The invention relates to protective leg clothing, in particular protective socks, against chemical and / or biological pollutants.
Bekannt sind Unterbeinschutzbekleidungen auf zivilem Gebiet, insbesondere medizinischem Gebiet. So ist z.B. in der EP 0 705 543 Bl eine Unterbeinschutzbekleidung beschrieben, die zur Vermeidung einer Verletzung oder eines Wiederauftretens einer Verletzung bei Sport- oder Trainingsaktivitäten eine Bandagenwirkung ergeben soll.Lower leg protective clothing is known in the civilian field, in particular in the medical field. For example, EP 0 705 543 B1 describes lower leg protective clothing which, in order to avoid injury or recurrence of an injury in sports or training activities, is said to produce a bandaging effect.
Bekannt sind auch wasserdichte, atmungsfähige Socken (siehe z.B. EP 0 386 144 Bl) .Waterproof, breathable socks are also known (see e.g. EP 0 386 144 Bl).
Die DE 199 18 425 AI beschreibt einen Schutzschuh, in welchem, ein Innenschuh mit einer atmungsaktiven Membran als Strumpf ausgebildet ist.DE 199 18 425 AI 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.EP 1 269 877 describes a protective suit as overall for protection against chemical pollutants.
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. 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.A disadvantage of known protective suits against chemical and / or biological pollutants in the military field is that they only reach up to the ankle and the feet are therefore not protected. Overboots made of 100% butyl are used to protect the feet. However, a disadvantage is that the boots can only be activated if the 'soldier has attracted the suit. However, since the protective suits are usually very stiff, putting on the boot is relatively difficult. The well-known overboots also have no breathability and are relatively bulky and large. Because 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 based on the object of providing under-leg protective clothing, in particular protective socks, which avoids the disadvantages mentioned above, in particular which is very comfortable to wear and can be worn like a conventional sock or stocking.
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 Faseroder Partikelform vorhanden ist, und eine innere textile Stoffläge aufweist.According to the invention, this object is achieved by a lower leg protective clothing, in particular a protective sock which has several layers, with an outer leg part and a laminate arranged in the interior of the outer leg part, which has a flexible, windproof and water-deflecting membrane which forms the outside of the laminate and which has at least one barrier for biological Forms pollutants, a carbon layer arranged under the membrane, in which carbon is present in fiber or particle form, and has 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 Unterbeinschutz- bekleidung 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.In addition to protection against chemical and / or biological pollutants, the lower leg protective clothing according to the invention also offers high wearing comfort. It is very flexible and can be worn like a "normal" stocking or socks. In particular, the lower leg protection according to the invention put on clothing before putting on the suit, which means that a person wearing a protective suit is put on more quickly in the event of an operation 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 is made breathable according to the invention, 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 can be an outer sock made of wool, cotton, silk, polyester, polypropylene, polyamide, polyacrylic, modifications or mixtures thereof if they are designed as socks. Protection against chemical and / or biological pollutants is achieved by the laminate according to the invention. In this way, the windproofness of the membrane prevents wind from entering the carbon layer underneath and thus impairing its effectiveness. Due to the watertightness, wetting or penetration of liquid chemicals into the carbon layer is also prevented, which would also lead to an impairment 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 pollutants, the membrane acts on a corresponding one. Also designed as a filter against pollutants.
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 .If liquid pollutants penetrate, they are distributed in the membrane and are generally blocked. Unless they are blocked - they diffuse through so slowly that they arrive at the carbon layer in an aggregate state where it is effective. This mechanism greatly increases the number of chemicals against which a protective effect is achieved. tries in practice have shown that the laminate according to the invention has a significantly better and, above all, a longer protective effect than known materials.
Bei Verwendung von hydrophilen Membranen, wie z.B. Polyester, Polyether, Polyester-Copolymer und ähnlichem, liegt keine Mikroporosität vor, wodurch eine Barriere gegen biologische Schadstoffe gegeben ist. Wasserdampfmoleküle können jedoch trotzdem hindurchtreten, Wasser hingegen nicht.When using hydrophilic membranes, e.g. There is no microporosity in polyester, polyether, polyester copolymer and the like, which creates a barrier against biological pollutants. However, water vapor molecules can still pass through, but water cannot.
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 carbon layer underneath can be made thinner without impairing its effectiveness. This increases the wearing comfort considerably because the heat-accumulating carbon layer is thinner.
Weitere vorteilhafte Materialien für die Membran sind z.B. auf Cellophan basierende Materialien, Polyvinylalkohol, Po- lyacrylamide, Polyurethane und Mischungen daraus.Other advantageous materials for the membrane are e.g. materials based on cellophane, polyvinyl alcohol, polyacrylamides, polyurethanes and mixtures thereof.
Bei Verwendung von mikroporösen Membranen, wie z.B. Polytet- rafluorethylen, wird trotz Winddichtheit und einer Wasserdichtheit eine Atmungsaktivität erreicht.When using microporous membranes, e.g. Polytetrafluoroethylene, breathability is achieved despite being windproof and watertight.
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. Die Kohlenstoffschicht kann aus einem Gewebe oder Gewirk mit 100 % aktivierten Fasern oder auch Aktivkohlekügelchen aufweisen, die auf ein Trägermaterial aufgetragen wurden.According to the invention, it is advantageous if a small pore size is selected such that only water vapor passes through the small pores. Because biological pollutants are generally larger, they are prevented from penetrating in this way. The carbon layer can have a woven or knitted fabric with 100% activated fibers or also activated carbon spheres which have been applied to a carrier material.
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.The wearing comfort is improved even more if, in addition to the outer leg part, an inner leg part on the inside, i.e. the side of the laminate facing the carrier is arranged. The inner leg part can be made from synthetic fibers, such as e.g. Polypropylene, polyamide, polyester, modifications and mixtures 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.A textile fabric can be provided as the textile fabric layer, which forms a mechanical protective layer for the carbon layer. On the outside, in addition to its protective effect against pollutants, the membrane also forms a mechanical protective layer for the fiber layer.

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 using a protective sock. Of course, other lower leg protective clothing, such as Stockings, possible in the configuration according to the invention.
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 protective socks shown in FIGS. 1 and 2 have an outer sock 1 as the outer leg part. A laminate 2 is arranged in the interior of the outer sock 1, the structure of which is described in more detail below with reference to FIGS. 6 and 7. An inner sock 3 is arranged on the inside as the end of the protective sock as an 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 Fußspit- zenbereich, z.B. mittels Fahnen, erfolgen.The three layers, consisting of outer socks 1, laminate 2 and inner socks 3, are connected to one another and are put on together as a protective sock. The connection between the three layers can e.g. by sewing and / or gluing. The sewing can 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 wei- chem, flauschigem gesponnenem Garn gestrickt sein, damit Druckstellen am Fuß verhindert werden.The inner sock 3 can optionally be made hydrophilic. At the seams, the inner socks 3 should be made of chem, fluffy spun yarn, so that pressure points 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 longer than the laminate 2 and the outer socks 1, the inner socks 3 can be placed at the upper end over the laminate 2 and the outer socks 1 in the form of a cuff, as shown in dashed lines in FIGS. 1 and 2 is. In the case of a hydrophilic inner sock 3, moisture absorbed in this way can be transported to the outside and can evaporate there.
Außensocken 1 und Innensocken 2 können aus mehreren Schnitt— teilen 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 from several cut parts. Of course, outer socks 1 and inner socks 3 can also be woven or knitted without a seam. The laminate 2 can be produced from three cut parts, as can be seen from FIGS. 3 to 5 - FIG. 3 shows the cut part for a shaft 4 of the laminate. Fig. 4 shows the cut part for an upper part 5 and Fig. 5 shows a cut part for a sole 6 of the laminate - the same or similar applies to the outer socks 1 if this is also made from 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. 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 Stoffläge 9 vorgesehen.The three cut pieces can be joined using a flatlock stitch or zigzag stitch, the seams being sealed with a waterproof material. The waterproof material can consist, for example, of a waterproof seam sealing tape. It is also possible to connect the three cut parts with water and gas-tight glue, which should also form a barrier against pollutants. FIG. 6 shows in a greatly enlarged cross section the structure of the protective sock from the three layers, namely the outer sock 1, the laminate 2 and the inner sock 3. FIG. 6 also shows the structure of the laminate 2, which consists of three layers exists. The outer side, ie the side of the laminate 2 facing away from the carrier, is formed by a membrane 7. Under the membrane 7, ie on the side facing the support, there is a carbon layer 8 and a textile fabric layer 9 is provided as the inner layer.
Die Membran 7, die Kohlenstoffschicht 8 und die textile Stofflage 9 werden in bekannter Weise durch ein Laminie- rungsverfahren 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 means of a point-by-point lamination, adhesive being introduced point by point between the layers to be connected and then the layers being connected to one another 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.Fig. 7 shows basically the same structure as the embodiment of the protective sock according to Fig. 6. The only difference is that in this case the inner socks 3 are missing, so that the textile layer 9 of the laminate 2, which in this case then will form hydrophilic, rests on the foot of the wearer. The membrane 7 is designed to be flexible so that stretching in both the transverse and longitudinal directions is possible and tearing is avoided.
Wenn die Kohlenstoffschicht 8 als Gewebe ausgebildet ist, ergeben sich sehr gute Wascheigenschaften. 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.If the carbon layer 8 is designed as a fabric, very good washing properties result. The active carbon layer 8 can be produced in fiber form from a knitted or woven 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 in such a way that activated carbon is formed with extremely fine pores, 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 can 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 from 800 to 2,000 m 2 / g, preferably between 1,000 to 1,200 m 2 / g.
