Description

Die Erfindung betrifft ein Bekleidungsstück, insbesondere Unterbekleidungsstück für Personen im Militär- und im Zivilschutzbereich.The invention relates to a piece of clothing, in particular Underwear for people in the military and in civil protection.

Bekleidungsstücke, insbesondere Unterbekleidungsstükke, die als Schutz vor Kälte dienen, weisen als wesentliches Bestandteil ein Kunststoffvlies, zumeist ein Polyestervlies, auf. Mit diesem Material wird eine sehr gute Isolation gegen Witterungseinflüsse, insbesondere als Kälteschutz erreicht. Nachteilig bei den bekannten Bekleidungsstücken ist jedoch, daß diese sehr leicht brennbar sind. Dies bedeutet, daß gerade im Militär- und im Zivilschutzbereich, wobei Personen häufig auch in der Nähe von offenen Flammen arbeiten oder sich aufhalten, wie z.B. Feuerwehrleute bei einem Brand oder Soldaten und Zivilschutzeinheiten an einem offenen Feuer oder dort lagern, eine nicht unerhebliche Gefahr für die mit derartigen leichtentzündbaren Bekleidungsstücken versehenen Personen besteht.Articles of clothing, in particular pieces of underwear, that serve as protection from the cold, have essentials Part of a plastic fleece, mostly a polyester fleece on. With this material one very good insulation against weather influences, in particular achieved as protection against the cold. A disadvantage of the known clothing is, however, that this are very flammable. This means that straight in the military and civil protection area, with people often work near open flames or stay, e.g. Firefighters at one Fire or soldiers and civil protection units on one open fire or store there, a not inconsiderable Danger to those with such highly flammable Clothing provided persons exists.

Der vorliegenden Erfindung liegt daher die Aufgabe zugrunde, ein Bekleidungsstück, insbesondere ein Unterbekleidungsstück für Personen im Militär- und im Zivilschutzbereich zu schaffen, welches nicht so leicht entzündbar ist, wobei jedoch die guten Isolierungseigenschaften erhalten bleiben sollen und im Bedarfsfalle auch ein hoher Tragekomfort gegeben ist.The present invention is therefore based on the object based on an item of clothing, in particular an undergarment for people in the military and in To create a civil protection area, which is not so is easily flammable, but the good insulation properties should be preserved and if necessary it is also very comfortable to wear.

Erfindungsgemäß wird diese Aufgabe durch die in Anspruch 1 genannte Merkmalskombination gelöst.According to the invention, this object is achieved by the 1 combination of features mentioned solved.

In der Praxis hat sich herausgestellt, daß durch die erfindungsgemäße Kombination der beiden Vliese mit den dazwischenliegenden diskreten Flocken aus Blähgraphit, ein deutlich verbessertes flammhemmendes Bekleidungsstück geschaffen worden ist, wobei jedoch durch die beiden Vliese - entsprechend ihrer Materialauswahlsehr gute Isolationseigenschaften erreichbar sind.In practice it has been found that the combination of the two nonwovens according to the invention with the intermediate discrete flakes made of expanded graphite, a significantly improved flame retardant garment has been created, however by the two fleeces - according to their choice of materials good insulation properties can be achieved.

Grundsätzlich ist die Verwendung von Blähgraphit als flammhemmendes Material auf dem Bausektor als Dämm- und Isolierstoff, im Heimtextilienbereich als Teppich und im Automobil- und Filterbereich bekannt, aber dabei waren stets Flächengebilde als Trägermaterial vorgesehen. Basically, the use of expanded graphite as flame retardant material in the construction sector as insulation and insulating material, in the home textile sector as a carpet and known in the automotive and filter sector, but in the process fabrics were always intended as the carrier material.

In überraschender Weise hat man jedoch festgestellt, daß sich diskrete Flocken aus Blähgraphit auch in der Bekleidung bei entsprechender Kombination mit den beiden Vliesen ebenfalls dazu eignen, einem Bekleidungsstück einen höheren Widerstand gegen eine Entzündung zu geben, wobei gleichzeitig die Haupteigenschaft des Bekleidungsstückes, nämlich ein Schutz gegen Witterungseinflüsse, insbesondere ein Kälteschutz, nicht beeinträchtigt wird.Surprisingly, however, it has been found that discrete flakes of expanded graphite can also be found in the Clothing with the appropriate combination with the two Nonwovens are also suitable for an item of clothing a higher resistance to inflammation to give, while at the same time the main characteristic of the Item of clothing, namely protection against the effects of weather, especially cold protection, not is affected.

Als mögliche vorteilhafte Materialien für das erste Vlies, das z.B. außenseitig angeordnet ist, können Polyesterfasern verwendet werden. Für das zweite Vlies, das auf der dem Träger zugewandten Seite ein Innenvlies bilden kann, kann ebenfalls Polyester oder auch Polyamid vorgesehen sein.As possible advantageous materials for the first Fleece, e.g. is arranged on the outside, polyester fibers be used. For the second fleece, an inner fleece on the side facing the carrier can also form polyester or polyamide may also be provided.

Eine weitere deutliche Erhöhung des Tragekomforts ergibt sich, wenn in einer sehr vorteilhaften Ausgestaltung der Erfindung vorgesehen ist, daß zwischen einem der beiden Vliese und den Flocken aus Blähgraphit eine wasserdampf- und luftdurchlässige Membrane angeordnet ist.Another significant increase in comfort results himself when in a very advantageous embodiment the invention provides that between a of the two fleeces and the flakes made of expanded graphite Water vapor and air permeable membrane arranged is.

Es hat sich herausgestellt, daß trotz der Flocken aus Blähgraphit eine Atmungsfähigkeit des Bekleidungsstükkes erreicht werden kann, wenn man in der angegebenen Weise eine wasserdampf- und luftdurchlässige Membrane anordnet. In vorteilhafter Weise wird man dabei die Verbindung zu den benachbart liegenden Materialienzumindest auf einer Seite - als Punktverklebung vornehmen, damit über die Poren der Membrane eine gute Atmungsfähigkeit bzw. eine Wasserdampf- und Luftdurchlässigkeit verbleibt.It turned out that despite the flakes Expandable graphite a breathability of the garment can be achieved if one is given in the Way a water vapor and air permeable membrane orders. Advantageously, you will be the Connection to the adjacent materials at least on one side - as a point glue, thus a good one over the pores of the membrane Breathability or water vapor and air permeability remains.

Die Flocken aus Blähgraphit können auf verschiedene Weise auf ein Vlies aufgebracht werden. In einer vorteilhaften Ausgestaltung sind die Flocken in einer Schmelzkleberschicht, die vor der Wärmebehandlung in Granulatform vorliegt, verteilt. Der Schmelzkleber wird dann auf eines der beiden Vliese aufgestreut, z.B. das zweite Vlies, wonach das Ganze z.B. über eine temperierte Langstrecke in einem Kalander läuft und unter Hitze und Druck miteinander verbunden, d.h. laminiert wird.Expandable graphite flakes can be made in different ways Way to be applied to a fleece. In an advantageous The flakes are in one design Hot melt adhesive layer, which before in the heat treatment Granular form is present, distributed. The hot melt adhesive is then sprinkled on one of the two fleeces, e.g. the second fleece, after which the whole e.g. over a tempered long distance runs in a calender and bonded together under heat and pressure, i.e. laminated becomes.

Bei einer Ausbildung als Drei-Schicht-Laminat mit einem ersten Vlies, den dazwischenliegenden Flocken aus Blähgraphit, welche in der Schmelzkleberschicht aufgenommen worden sind, und dem zweiten Vlies kann man die Temperierung und damit die Verbindung zu dem Drei-Schicht-Laminat in einem Arbeitsgang durchführen.When training as a three-layer laminate with one first fleece, the flakes in between Expandable graphite, which is absorbed in the hot melt adhesive layer and the second fleece can be used Tempering and thus the connection to the three-layer laminate perform in one operation.

Falls zur Erhöhung des Tragekomforts eine Membrane in den Verbund mit aufgenommen werden soll, so kann dies in einer sehr vorteilhaften Weiterbildung der Erfindung dadurch geschehen, daß über die Schmelzkleberschicht mit dem Blähgraphit das zweite Vlies mit der Membrane verbunden wird, während die Membrane über Klebepunkte mit dem ersten Vlies verbunden wird. If, to increase the comfort, a membrane in the association should be included, so this can in a very advantageous development of the invention by doing that over the hot melt adhesive layer with the expanded graphite the second fleece with the Membrane is connected while the membrane is over Glue dots are connected to the first fleece.

Nachfolgend ist ein Ausführungsbeispiel der Erfindung anhand der Zeichnung prinzipmäßig beschrieben, wobei die einzige Figur aus Übersichtlichkeitsgründen in einem stark vergrößerten Maßstab ausschnittsweise im Querschnitt einen Teil eines Bekleidungsstückes darstellt. Das Bekleidungsstück kann eine Unterbekleidung, wie z.B. Unterhemd, Unterhose oder Socken sein.The following is an embodiment of the invention described in principle with reference to the drawing, wherein the only figure for reasons of clarity in a greatly enlarged scale in sections Cross section represents part of a garment. The garment can be an undergarment, such as. Undershirt, underpants or socks.

Das Bekleidungsstück besteht aus einem ersten Vlies 1 aus Polyesterfasern, einer darunterliegenden Membrane 2, einer Schmelzkleberschicht 3, in die eine Vielzahl von diskreten bzw. einzelnen Flocken 4 aus Blähgraphit eingelegt sind und einem zweiten Vlies 5, das auf der von der Membrane 2 abgewandten Seite der Schmelzkleberschicht 3 liegt.The item of clothing consists of a first fleece 1 made of polyester fibers, an underlying membrane 2, a hot melt adhesive layer 3, into which a variety of discrete or individual flakes 4 made of expanded graphite are inserted and a second fleece 5, which on the side of the hot melt adhesive layer facing away from the membrane 2 3 lies.

Im allgemeinen wird das erste Vlies 1 aufgerauht sein und auf der Außenseite liegen (es kann aber auch flach hergestellt sein und innenseitig liegen), während das zweite Vlies 5 (eventuell auch aufgerauht) dem Träger des Bekleidungsstückes zugewandt ist. Selbstverständlich ist dieser Aufbau nur beispielsweise genannt. Als Membrane 2 können Materialien aus Komfortgründen verwendet werden, die unter dem Markennamen Goretex und Sympatex bekannt sind. Selbstverständlich sind jedoch auch noch andere Membrane im Rahmen der Erfindung möglich, welche eine entsprechende Amtungsaktivität gewährleisten.In general, the first fleece 1 will be roughened and lie on the outside (but it can also be flat be made and inside), while the second fleece 5 (possibly also roughened) the carrier the garment is facing. Of course this structure is only mentioned for example. As Membrane 2 can use materials for comfort reasons that are sold under the brand names Goretex and Sympatex are known. Of course, are other membranes are also possible within the scope of the invention, which guarantee a corresponding official activity.

Wenn das Bekleidungsstück ohne Membrane 2 vorgesehen ist, kann dessen Herstellung auf einfache Weise so erfolgen, daß der Schmelzkleberüberzug in fester Form, z.B. in Pulver- oder Granulatform auf eines der beiden Vliese 1 oder 5 aufgestreut wird, das andere Vlies darübergelegt wird und die Einheit unter Hitze und Druck zu einem Drei-Schicht-Aufbau miteinander verbunden wird.If the garment is provided without membrane 2 is, its production can be done in a simple manner take place that the hot melt adhesive coating in solid form, e.g. in powder or granule form on one of the two Fleece 1 or 5 is sprinkled, the other fleece is placed over it and the unit under heat and Pressure combined to form a three-layer structure becomes.

Wenn ein Bekleidungsstück in der dargestellten Form hergestellt werden soll, so kann dies z.B. dadurch erfolgen, daß man die Membrane 2 über Klebepunkte 6 mit dem ersten Vlies 1 verbindet und auf diese Weise ein Zwei-Lagen-Laminat herstellt.If a garment in the form shown to be produced, this can e.g. thereby take place that the membrane 2 over adhesive dots 6th connects to the first fleece 1 and in this way produces a two-layer laminate.

Auf das zweite Vlies 5 wird dann der Blähgraphit 4 mit dem pulverförmigen Schmelzkleber aufgestreut, ebenfalls thermisch behandelt, wobei der Schmelzkleber zur Bildung einer Schmelzkleberschicht 3 aktiv wird und damit nach einem vorangegangenen Auflegen des vorher gebildeten Zwei-Lagen-Laminates aus dem Vlies 1 und der Membrane 2 über die Schmelzkleberschicht 3 alle Materialien zu einer Einheit miteinander verbunden werden.Expandable graphite 4 is then applied to the second fleece 5 sprinkled on the powdery hot melt adhesive, likewise thermally treated, the hot melt adhesive for Formation of a hot melt adhesive layer 3 becomes active and after a previous hang up of the previous formed two-layer laminates from the fleece 1 and the membrane 2 all over the hot melt adhesive layer 3 Materials connected to one another become.

Anstelle einer Aufbringung der Flocken 4 aus Blähgraphit über einen pulverförmigen Schmelzkleber können selbstverständlich die Flocken 4 auch noch auf andere Weise mit dem dazugehörigen Vlies verbunden werden. So kann z.B. die Oberfläche des Vlieses 1 oder 5 mit einer wässrigen Polymerlösung besprüht werden, wobei das Aufstreuen der Flocken 4 aus Blähgraphit vor oder nach dem Besprühen erfolgen kann. Instead of applying the flakes 4 made of expanded graphite over a powdery hot melt adhesive of course the flakes 4 also on others Be connected with the associated fleece. So can e.g. the surface of the fleece 1 or 5 with a sprayed aqueous polymer solution, the Sprinkle the flakes 4 of expanded graphite before or after spraying can take place.

Ebenso ist es möglich, die Blähgraphitflocken 4 in Form einer Suspension oder Dispersion zusammen in wässrigen Polymerlösungen auf die Oberfläche des Vlieses 1 oder 5 aufzubringen. Die Durchmesser bzw. Größen der Flocken können z.B. zwischen 0,1 mm und einigen mm betragen.It is also possible to expand the expanded graphite flakes 4 in Form a suspension or dispersion together in aqueous polymer solutions on the surface of the fleece To apply 1 or 5. The diameters or sizes the flakes can e.g. between 0.1 mm and a few mm be.
