Definitions

  • the invention relates to a bullet-resistant protective vest consisting of a plurality of layers of fabrics made of aramid yarn, one on top of the other.

Abstract

Body armor comprising a plurality of laminated fabric layers from aramid yarn, wherein the filaments of the armid yarn have an individual titer of less than 1.5 dtex.

Description

Die Erfindung betrifft gemäß Oberbegriff des Anspruches 1 eines geschoßhemmende Schutzweste, bestehend aus mehreren, übereinandergeschichteten Lagen von Geweben aus Aramidgarn.According to the preamble of claim 1, the invention relates to a bullet-resistant protective vest consisting of a plurality of layers of fabrics made of aramid yarn, one on top of the other.

Derartige Schutzwesten sind beispielsweise aus Melliand Textilberichte 6/1981, Seite 463 bis 468 bekannt. Es wird dort darauf hingewiesen, daß Gewebe aus feinen Aramidgarnen, z.B. 220 oder 440 dtex in ballistischer Hinsicht günstiger sind als Gewebe aus gröberen Garnen. Weiterhin wird dort berichtet, daß wegen der hohen Kosten der feinen Garne aber allgemein eine Feinheit von 1100 dtex eingesetzt und zum Ausgleich der etwas schlechteren ballistischen Eigenschaften eine Erhöhung des Gesamtflächengewichtes in Kauf genommen wird. Es versteht sich, daß sich diese Titerangaben alle auf den Gesamttiter der verwendeten Aramidgarne beziehen.Protective vests of this type are known, for example, from Melliand Textile Reports 6/1981, pages 463 to 468. It is pointed out there that fabrics made from fine aramid yarns, e.g. In ballistic terms, 220 or 440 dtex are cheaper than fabrics made from coarser yarns. Furthermore, it is reported there that, because of the high cost of the fine yarns, a fineness of 1100 dtex is generally used and an increase in the total basis weight is accepted to compensate for the somewhat poorer ballistic properties. It is understood that these titer details all relate to the total titer of the aramid yarns used.

Aus der zitierten Literaturstelle kann geschlossen werden, daß bei gleichem Flächengewicht der Gesamtheit der verwendeten Lagen von Aramidgeweben durch Reduzierung des Gesamttiters der verwendeten Aramidgarne der ballistische Schutz erhöht, bzw. zur Erreichung des gleichen ballistischen Schutzes durch die Reduzierung des Gesamttiters der verwendeten Aramidgarne das Gesamtflächengewicht reduziert und somit der Tragkomfort verbessert werden kann.From the cited literature reference it can be concluded that with the same basis weight of all the layers of aramid fabrics used, the ballistic protection is increased by reducing the total titer of the aramid yarns used, or to achieve the same ballistic protection by reducing the total titer of the aramid yarns used, the total weight per unit area is reduced and thus the comfort can be improved.

Aufgabe der vorliegenden Erfindung ist es, eine weitere Schutzweise der eingangs genannten Art zur Verfügung zu stellen, bei der ebenfalls bei gleichem Gesamtflächengewicht der Lagen aus Aramidgeweben der ballistische Schutz erhöht bzw. bei gleichem ballistischem Schutz das Gesamtflächengewicht reduziert und somit der Tragekomfort verbessert werden kann.The object of the present invention is to provide a further type of protection of the type mentioned at the outset, in which the ballistic protection is likewise increased with the same total basis weight of the layers of aramid fabrics or the total basis weight is reduced with the same ballistic protection and the wearing comfort can thus be improved.

Erfindungsgemäß kann diese Aufgabe bei einer Schutzweste der eingangs genannten Art dadurch gelöst werden, daß die Filamente des Aramidgarns einen Einzeltiter von weniger als 1,5 dtex, vorzugsweise einen Einzeltiter von 0,8 bis 1,4 dtex aufweisen.According to the invention, this object can be achieved in a protective vest of the type mentioned at the outset in that the filaments of the aramid yarn have an individual titer of less than 1.5 dtex, preferably an individual titer of 0.8 to 1.4 dtex.

In der Patentliteratur werden zwar Aramidgarne mit einem Einzeltiter von weniger als 1,5 dtex beschrieben, doch sind derartige Garne bisher auf dem Markt nicht erhältlich.In the patent literature, aramid yarns with a single titer of less than 1.5 dtex are described, but such yarns have not yet been available on the market.

Neuerdings ist auch ein Aramidgarn bekannt geworden, dessen Filamente einen Einzeltiter von 1,58 dtex aufweisen, die bei ballistischen Laminaten im Kombination mit anderen Garnen Verwendung finden (US-PS 4 181 768).An aramid yarn has recently become known whose filaments have an individual titer of 1.58 dtex, which are used in ballistic laminates in combination with other yarns (US Pat. No. 4,181,768).

Doch sind die ballistischen Eigenarten von ballistischen Laminaten und ballistischen Mehrlagengeweben nicht miteinander vergleichbar.However, the ballistic characteristics of ballistic laminates and ballistic multi-layer fabrics are not comparable.

Als günstige Einzeltiter der Filamente des Aramidgarnes beim Einsatz in geschoßhemmenden Schutzwesten gattungsgemäßer Art haben sich 1,46 dtex, 1,12 dtex und 0,84 dtex erwiesen.1.46 dtex, 1.12 dtex and 0.84 dtex have proven to be favorable single titer of the filaments of the aramid yarn when used in bullet-resistant protective vests of the generic type.

Die der Erfindung zugrundeliegende Aufgabe wird besonders gut dann gelöst, wenn bei den Aramidgarnen nicht nur der Einzeltiter der filamente reduziert wird, sondern auch der Gesamttiter weniger als 1100 dtex, vorzugsweise weniger als 850 dtex beträgt.The object on which the invention is based is particularly well achieved if not only the individual titer of the filaments is reduced in the aramid yarns, but also the total titer is less than 1100 dtex, preferably less than 850 dtex.

Die Erfindung wird anhand der beigefügten Figur erläutert.The invention is explained with reference to the attached figure.

Die Schutzweste kann äußerlich wie bekannte Westen konfektioniert werden (nicht dargestellt). Zwischen den außen sichtbaren Stoffen besteht eine geschoßhemmende Schutzweste aus mehreren Lagen 1 von Geweben aus Aramidgarnen, die miteinander beispielsweise durch Vernähen verbunden sein können. Um den sogenannten Traumeffekt zu verhindern, kann bei Polizeiwesten auf der Körperseite ein Schockabsorber 2 angeordnet sein. Bei Splitterschutzwesten im militärischen Bereich ist ein Schockabsorber entbehrlich.The protective vest can be assembled externally like known vests (not shown). Between the materials visible from the outside there is a bullet-resistant protective vest consisting of several layers 1 of fabrics made of aramid yarns, which can be connected to one another, for example, by sewing. In order to prevent the so-called dream effect, a shock absorber 2 can be arranged on the body side of police vests. A shock absorber is not necessary for splinter protection vests in the military sector.

Erfindungsgemäß hat es sich herausgestellt, daß der ballistische Effekt durch Verwendung von Aramidgarnen, deren Filamente einen Einzeltitervon weniger als 1,5 dtex aufweisen, zur Herstellung der Gewebelagen 1 wesentlich verbessert wird.According to the invention, it has been found that the ballistic effect is significantly improved by using aramid yarns, the filaments of which have a single titer of less than 1.5 dtex, for the production of the fabric layers 1.

Beispielexample

Es wurden zwei Gewebe hergestellt, die folgende Merkmale aufwiesen.

Beide Gewebe wurden gewaschen und nach gleicher Rezeptur wasserabweisend ausgerüstet.Both fabrics were washed and made water-repellent according to the same recipe.

Bei dem Gewebepaket aus Geweben A (Vergleich) wurde ein durchschnittlicher Vso-Wert (gemessen) von 458 m/sec festgestellt, während das Gewebepaket aus Geweben B (erfindungsgemäß) einen durchschnittlichen Vso-Wert (gemessen) von 480 m/sec aufwies, was einer Steigerung von etwa 5% entspricht.The fabric package from fabrics A (comparison) was found to have an average Vso value (measured) of 458 m / sec, while the fabric package from fabrics B (according to the invention) had an average Vso value (measured) of 480 m / sec, which corresponds to an increase of about 5%.
