Description

Die Erfindung betrifft eine mindestens ein Stichschutzmaterial umfassende Stichschutzkleidung.The invention relates to a puncture protection clothing comprising at least one puncture protection material.

Kleidung zum Schutz vor Angriffen durch Stichwaffen sind bekannt. WO 00/08411 beschreibt ein Stichschutzmaterial aus mindestens zwei Geweben, die über einen Polymerfilm miteinander verbunden sind, wobei die Gewebe aus Garnen mit einer Festigkeit von mindestens 900 MPa bestehen, und der die Gewebe verbindende Polymerfilm eine Festigkeit von mindestens 10 MPa und einen Biegemodul von 1500 bis 4500 MPa aufweist.Clothing to protect against attacks by stabbing weapons are known. WO 00/08411 describes a sting protector material of at least two fabrics joined together by a polymeric film, the fabrics consisting of yarns having a tenacity of at least 900 MPa, and the fabric-bonding polymer film having a tenacity of at least 10 MPa and a flexural modulus of from 1500 to 4500 MPa having.

Zwar zeigt das in WO 00/08411 offenbarte Material bereits eine hohe Stichschutzwirkung. Jedoch besteht immer noch ein Bedürfnis nach Stichschutzkleidung mit einem Stichschutzmaterial, das bei gleichem Flächengewicht einen noch besseren Schutz gewährleistet. Eine derartige Stichschutzkleidung hätte den zusätzlichen Vorteil, das ein bestimmtes Maß an Schutz mit einem kleineren Flächengewicht als bisher erreichbar wäre, wodurch sich der Tragekomfort erhöhen würde.Although that shows in WO 00/08411 revealed material already a high stab protection effect. However, there is still a need for puncture protective clothing with a puncture protection material, which ensures even better protection at the same basis weight. Such puncture protection clothing would have the additional advantage that a certain level of protection would be achieved with a smaller basis weight than hitherto, which would increase the wearing comfort.

Daher stellt sich die vorliegende Erfindung die Aufgabe, eine Stichschutzkleidung mit einem Stichschutzmaterial zur Verfügung zu stellen, das bei gleichem Flächengewicht einen verbesserten Stichschutz gewährt bzw. bei gleichem Schutz ein geringeres Flächengewicht aufweist.Therefore, the present invention has the object to provide a puncture protection clothing with a puncture protection material available at the same basis weight granted an improved puncture protection or at the same protection has a lower basis weight.

Diese Aufgabe wird gelöst durch eine Stichschutzkleidung umfassend mindestens ein Stichschutzmaterial, das eine Anordnung umfaßt, die aus einer oder mehreren aufeinanderliegenden Gewebelagen besteht, wobei jede Gewebelage flexibel ist und aus mindestens einem mit mindestens einem Polymerfilm verbundenen Gewebe aus Garnen mit einer Festigkeit von mindestens 900 MPa besteht, und wobei das Stichschutzmaterial eine der Angriffsseite zugewandte Außenoberfläche und eine von der Angriffsseite abgewandte Innenoberfläche aufweist, und das dadurch gekennzeichnet ist, dass das Stichschutzmaterial weiterhin mindestens eine weitere Lage aus Filz aufweist, die jeweils auf einer der Gewebelagen angeordnet ist, und mindestens eine der weiteren Lagen aus Filz an der Außenoberfläche des Stichschutzmaterials angeordnet ist.This object is achieved by a puncture protective clothing comprising at least one sting protection material comprising an assembly consisting of one or more superposed fabric layers, each fabric layer being flexible and at least one fabric joined to at least one polymer film of yarns having a strength of at least 900 MPa and wherein the sting protection material has an outer surface facing the attack side and an inner surface facing away from the attack side, and characterized in that the sting protection material further comprises at least one further layer of felt, which is arranged on each of the fabric layers, and at least one the further layers of felt is arranged on the outer surface of the puncture protection material.

Überraschenderweise wurde festgestellt, daß dadurch, dass das Stichschutzma-terial weiterhin mindestens eine weitere Lage aus Filz aufweist, die jeweils auf einer der Gewebelagen angeordnet ist, eine Stichschutzkleidung resultiert, die bei gleichem Flächengewicht einen besseren Schutz bietet und es somit möglich macht, den gleichen Schutz bei einem geringeren Flächengewicht, d.h. bei höherem Tragekomfort, zu gewähren.Surprisingly, it has been found that the fact that the stab protection material further comprises at least one further layer of felt, which is respectively arranged on one of the fabric layers, a puncture protective clothing results, which provides better protection at the same basis weight and thus makes it possible, the same Protection at a lower basis weight, ie with higher wearing comfort, to grant.

Dass das Stichschutzmaterial der Stichschutzkteidung erfindungsgemäß weiterhin mindestens eine weitere Lage aus Filz aufweist, die jeweils auf einer der Gewebelagen angeordnet ist, bedeutet, dass die mindestens eine Lage aus Filz auf jeweils einer der Gewebelagen lediglich punktuell vernäht oder punktuell verklebt oder nur aufgelegt ist, wobei die zuletzt genannte Ausführungsform wegen der Einfachheit ihrer Ausführung bevorzugt istAccording to the invention, that the puncture protection material of the puncture protection has at least one further layer of felt, which is arranged on one of the fabric layers, means that the at least one layer of felt is sewn on at one of the fabric layers only selectively or adhesively bonded or only applied, wherein the latter embodiment is preferred because of the simplicity of its design

Besonders schutzwirksam und daher erfindungsgemäß bevorzugt ist eine Stichschutzkleidung, bei der mindestens eine Lage aus Filz an der Innenoberfläche des Stichschutzmaterials angeordnet ist.Particularly protective and therefore preferred according to the invention is a puncture protection clothing in which at least one layer of felt is arranged on the inner surface of the puncture protection material.

Ferner ist eine weitere Ausführungsform der erfindungsgemäßen Stichschutzkleidung besonders schutzwirksam und daher bevorzugt, die mindestens drei Gewebelagen umfaßt und wobei mindestens eine Lage aus Filz zwischen den Gewebelagen angeordnet ist und wobei die Anzahl der Gewebelagen zur Außenoberfläche kleiner ist als die Anzahl der Gewebelagen zur Innenoberfläche.Furthermore, another embodiment of the puncture protection clothing according to the invention is particularly protective and therefore preferred, which comprises at least three layers of fabric and wherein at least one layer of felt between the fabric layers is arranged and wherein the number of fabric layers to the outer surface is smaller than the number of layers of fabric to the inner surface.

Es ist von Vorteil, wenn in der erfindungsgemäßen Stichschutzkleidung die mindestens eine Lage aus Filz aus einem aromatischen Polyamid, d.h. aus einem Aramid und insbesondere aus einem p-Aramid besteht.It is advantageous if in the puncture protective clothing according to the invention the at least one layer of felt made of an aromatic polyamide, i. consists of an aramid and in particular a p-aramid.

Die Lage aus Filz kann nach irgendeinem der bekannten Herstellungsverfahren für Filze erzeugt werden, wodurch eine Lage aus Filz entsteht, die z.B. thermisch, durch Einwirkung eines Wasserstrahl oder von Luft oder durch Nadeln verfestigt ist Bevorzugt ist die Filzlage ein genadelter Fitz. Ein derartiger Filz ist beispielsweise von der Fa. Job (Kinna, Schweden) erhältlich.The felt layer may be produced by any of the known felt production processes, thereby forming a layer of felt, e.g. thermally, is solidified by the action of a jet of water or air or by needles. Preferably, the felt layer is a needled Fitz. Such a felt is available, for example, from the company Job (Kinna, Sweden).

Ferner ist es für die erfindungsgemäße Stichschutzkleidung bevorzugt, dass jedes Gewebe jeder Gewebelage aus Garnen mit einer Festigkeit von 900 bis 8000 MPa, noch günstiger von 1500 bis 6000 MPa und am günstigsten von 3000 bis 6000 MPa besteht. Derartige Festigkeiten weisen praktisch alle auch für den Einsatz zum ballistischen Schutz geeigneten Garne auf, wie beispielsweise Garne aus Polyolefin, insbesondere Polyethylen, aus Polyamid, Polyimid, Polyester oder Poly (p-phenylene - 2,6 - benzobisoxazole). Besonders günstig haben sich Garne aus Aramiden erwiesen, insbesondere solche aus p-Aramiden.Further, for the puncture protective clothing of the present invention, it is preferable that each fabric of each fabric layer consists of yarns having a tenacity of 900 to 8,000 MPa, more preferably 1,500 to 6,000 MPa, and most preferably 3,000 to 6,000 MPa. Such strengths have virtually all suitable for use for ballistic protection yarns, such as yarns of polyolefin, in particular polyethylene, polyamide, polyimide, polyester or poly (p-phenylene - 2,6 - benzobisoxazole). Yarns made of aramids have proven particularly favorable, in particular those of p-aramids.

Für die erfindungsgemäße Stichschutzkleidung hat es sich bestens bewährt, dass jedes Gewebe jeder Gewebelage Leinwandbindung aufweist.For the sting protective clothing according to the invention, it has proven to be very good that every fabric of each fabric layer has plain weave.

Ferner hat es sich für die erfindungsgemäße Stichschutzkleidung bestens bewährt, dass jedes Gewebe jeder Gewebelage eine Gewebedichte, berechnet nach Walz, von 15 bis 80 %, bevorzugt von 15 bis 60 % autweist.Furthermore, it has proven very well for the sting protective clothing according to the invention that each fabric of each fabric layer has a fabric density, calculated according to rolling, of 15 to 80%, preferably 15 to 60%.

Die Gewebedichte nach Walz wird nach folgender Formel bestimmt: DG = d k + d s 2 f k f s

Figure imgb0001
The fabric density after rolling is determined according to the following formula: DG = d k + d s 2 f k f s

Hierbei bedeuten:

dk =
Substanzdurchmesser des Kettgarnes in mm
ds =
Substanzdurchmesser des Schußgarnes in mm
fk =
Kettfäden pro cm
fs =
Schußfäden pro cm
Where:
d k =
Substance diameter of the warp yarn in mm
d s =
Substance diameter of the weft yarn in mm
f k =
Warp threads per cm
f s =
Wefts per cm

Der Substanzdurchmesser dk bzw. ds der Garne wird wie folgt berechnet. d = Titer ½ / 88 , 5 Dichte ½

Figure imgb0002

wobei d entweder dk oder ds bedeutet, der Titer des entsprechenden Garnes in dtex und die Dichte des Garnes in g/cm3 eingesetzt wird.The substance diameter d k or d s of the yarns is calculated as follows. d = titres ½ / 88 . 5 density ½
Figure imgb0002

where d is either d k or d s , the denier of the corresponding yarn in dtex and the density of the yarn in g / cm 3 is used.

Die oben angegebenen Werte gelten insbesondere für Gewebe in Leinwandbindung. Liegen von der Leinwandbindung abweichende Bindungen vor, so muß ein Bindungs-Korrekturfaktor in die Berechnung einbezogen werden. Für diesen Bindungs-Korrekturfaktor werden beispielsweise bei Geweben in speziellen Bindungsarten folgende Werte eingesetzt: Bindungsart Bindungs-Korrekturfaktor Panarnabindungen 2:2 0,56 Köperbindungen 2:1 0,70 Köperbindungen 2:2 0,56 Köperbindungen 3:1 0,56 Köperbindungen 4:4 0,38 Satin 1:4 0,49 The above values apply in particular to plain weave fabrics. If there are deviations from the plain weave, a binding correction factor must be included in the calculation. For this binding correction factor, for example, the following values are used for fabrics in special weave types: weave Weave correction factor Panama Bindings 2: 2 0.56 Twill weaves 2: 1 0.70 Twill weaves 2: 2 0.56 Twill weaves 3: 1 0.56 Twill bonds 4: 4 0.38 Satin 1: 4 0.49

Mit diesen Korrekturfaktoren wird die gemäß der Formel nach Walz errechnete Gewebedichte DG multipliziert.
Die Gewebedichte DG nach Walz wird in % Gewebedichte angegeben. Bei sehr dichten Geweben können Werte über 100 % auftreten.
These correction factors are used to multiply the tissue density DG calculated according to the formula according to Walz.
The fabric density DG after rolling is given in% fabric density. Values over 100% can occur with very dense fabrics.

Dass in der erfindungsgemäßen Stichschutzkleidung jede Gewebelage aus mindestens einem mit mindestens einem Polymerfilm verbundenen Gewebe besteht, bedeutet beispielsweise, dass ein Gewebe mit einem Polymerfilm verbunden ist. Dabei kann entweder der Polymerfilm oder das Gewebe der der Angriffsseite zugewandten Außenoberfläche des Stichschutzmaterials näher sein.The fact that in the stab-resistant clothing according to the invention each fabric layer consists of at least one fabric connected to at least one polymer film means, for example, that a fabric is bonded to a polymer film. In this case, either the polymer film or the fabric may be closer to the outer surface of the puncture protection material facing the attack side.

In einer bevorzugten Ausführungsform der erfindungsgemäßen Stichschutzkleidung besteht jede Gewebelage aus einem Gewebe, das auf beiden Seiten mit einem Polymerfilm verbunden ist.In a preferred embodiment of the puncture protection clothing according to the invention, each fabric layer consists of a fabric which is connected on both sides with a polymer film.

In einer weiteren bevorzugten Ausführungsform der erfindungsgemäßen Stichschutzkleidung besteht jede Gewebelage aus zwei über einen Polymerfilm verbundenen Geweben, wobei es sich als besonders vorteilhaft erwiesen hat, dass jede Gewebelage aus zwei, über einen Polymerfilm miteinander laminierten Geweben besteht.In a further preferred embodiment of the puncture protection clothing according to the invention, each fabric layer consists of two woven fabrics connected by a polymer film, wherein it has proved to be particularly advantageous that each fabric layer consists of two woven fabrics laminated together by a polymer film.

Günstig ist es, wenn der die beiden Gewebe der Lage verbindende Polymerfilm eine Bruchdehnung von mindestens 80 %, beispielsweise 100 % oder 120 % aufweist.It is favorable if the polymer film connecting the two fabrics of the layer has an elongation at break of at least 80%, for example 100% or 120%.

Wie auch in WO 00/08411 soll auch bei vorliegender Erfindung der Biegemodul (flexural modulus) gemäß ASTM D-790, die Festigkeit des Films gemäß ASTM D-638, die Bruchdehnung gemäß ASTM D-638 und die Festigkeit des Garns gemäß ASTM D-885 bestimmt werden.As well as in WO 00/08411 Also in the present invention, flexural modulus according to ASTM D-790, strength of the film according to ASTM D-638, elongation at break according to ASTM D-638 and strength of the yarn according to ASTM D-885 shall be determined.

Das dadurch gebildete erfindungsgemäße Stichschutzmaterial wird mit einem Spanngurt auf dem Hintergrundmaterial befestigt und wie vorstehend beschrieben die Stichfestigkeit gemessen. Der Aufbau der getesteten Materialien; ihre Flächengewichte, die Einzelwerte der Penetration und die dazugehörigen arithmetischen Mittelwerte, die, wie bereits erwähnt, in Abwandlung der vorstehend beschriebenen Norm als Stichfestigkeiten bezeichnet werden, sind in der folgenden Tabelle zusammengefasst. Dabei ist die Stichfestigkeit umso besser, je kleiner der angegebene Wert ist. Beispie I Aufbau Flächengewicht (g/m2) Einzelwerte der Penetration (mm) Stichfestigkeit (mm) 1 16 Gewebelagen 5680 26 28 29 27,7 2 16 Lagen aus Filz 5600 ca. 25 ca. 25 3 14 Gewebelagen 2 Lagen aus Filz 5670 29, 26, 17, 32 26,0 4 2 Lagen aus Filz 14 Gewebelagen 5670 22, 15, 24, 23 21,0 5 1 Lage aus Filz 15 Gewebelagen 5675 12, 20, 18, 30, 16, 13, 16, 17 17,8 6 1 Lage aus Filz 14 Gewebelagen 1 Lage aus Filz 5670 0, 14, 14, 10, 19, 0, 27, 15 12,4 In Example 6 are placed on 1 of the layers of felt 14 of the above-mentioned layers of fabric and on the 14 layers of fabric 1 of the layers just described felt. The sting protection material according to the invention thus formed is fastened with a tension belt on the background material and, as described above, the puncture resistance is measured. The structure of the tested materials; their basis weights, the individual values of the penetration and the associated arithmetic mean values, which, as already mentioned, are referred to as random strengths in a modification of the standard described above, are summarized in the following table. The smaller the specified value, the better the puncture resistance. Example I construction Basis weight (g / m 2 ) Individual values of penetration (mm) Puncture resistance (mm) 1 16 tissue layers 5680 26 28 29 27.7 2 16 layers of felt 5600 about 25 about 25 3 14 layers of fabric 2 layers of felt 5670 29, 26, 17, 32 26.0 4 2 layers of felt 14 layers of fabric 5670 22, 15, 24, 23 21.0 5 1 layer of felt 15 layers of fabric 5675 12, 20, 18, 30, 16, 13, 16, 17 17.8 6 1 layer of felt 14 layers of fabric 1 layer of felt 5670 0, 14, 14, 10, 19, 0, 27, 15 12.4

Die Tabelle zeigt, dass bereits durch den Ersatz einer Gewebelage durch eine Lage aus Filz die Stichfestigkeit deutlich verbessert wird (vergleiche die Beispiele 1 und 5).The table shows that even the replacement of a fabric layer by a layer of felt significantly improves the puncture resistance (compare Examples 1 and 5).

Generell sind die Stichfestigkeiten in solchen Stichschutzmaterialien, in denen die Lage aus Filz auf die Außenoberfläche gelegt ist, die dem fallenden Spieß zugewandt ist, besser als in Stichschutzmaterialien, in denen die Lage aus Filz auf die Innenoberfläche gelegt ist, die dem Hintergrundmaterial zugewandt ist (vergleiche Beispiele 3 und 4).In general, the puncture strengths in such puncture protective materials, in which the layer of felt is placed on the outer surface facing the falling spit, are better than in puncture protection materials in which the layer of felt is laid on the inner surface facing the background material ( compare Examples 3 and 4).

Die beste Stichfestigkeit wurde mit dem Stichschutzmaterial von Beispiel 6 erreicht. Bei den beiden Einzelversuchen, welche Einzelwerte der Penetration von 0 mm ergaben, wurde der Spieß sogar verbogen. Übersetzt in eine reale Bedrohungssituation, d.h. in einen Angriff mit einer dem Spieß entsprechenden Stichwaffe, bedeutet das Ergebnis, das bei Verwendung der 16 Gewebelagen des Standes der Technik der Spieß etwa 28 mm in den Körper eindringen würde (siehe Beispiel 1), während das erfindungsgemäße Stichschutzmaterial von Beispiel 6 bewirkt, dass der Spieß nur etwa 12 mm und somit 16 mm weniger tief in den Körper eindringen würde. Dabei ist das Flächengewicht des erfindungsgemäßen Stichschutzmaterials mit 5670 g/m2 sogar etwas geringer als das der eben genannten 16 Gewebelagen des Standes der Technik (5680 g/m2). Folglich kann ein erfindungsgemäßes Stichschutzmaterial zur Verfügung gestellt werden, das bei einer Stichfestigkeit von 28 mm ein Flächengewicht aufweist, das deutlich kleiner als 5680 g/m2 ist und somit bei gleicher Stichfestigkeit wie bei den 16 Gewebelagen des Standes der Technik einen deutlich besseren Tragekomfort bietet.The best puncture resistance was achieved with the puncture protection material of Example 6. In the two individual experiments, which yielded individual values of penetration of 0 mm, the skewer was even bent. Translated into a real threat situation, ie in an attack with a spit corresponding stitch weapon, the result means that when using the 16 fabric layers of the prior art spit would penetrate about 28 mm into the body (see Example 1), while the inventive Sting protection material of Example 6 causes the skewer to penetrate only about 12 mm and thus 16 mm less deeply into the body. The surface weight of the sting protection material according to the invention with 5670 g / m 2 is even slightly lower than that of the just mentioned 16 fabric layers of the prior art (5680 g / m 2 ). Consequently, a sting protection material according to the invention can be made available which, with a puncture resistance of 28 mm, has a weight per unit area which is considerably smaller than 5680 g / m 2 and thus offers significantly better wearing comfort with the same stich resistance as in the 16 fabric layers of the prior art ,
