Description

Protective textile against ballistic effects

The invention relates to a protective textile against ballistic effects for e.g. Protective vests or linings such as the interior linings of vehicles.

Protective textiles against ballistic effects are intended to protect the wearer from projectiles (ballistic protection) and, if necessary, against attacks with knives (stab protection). It is not only intended to prevent the projectile from penetrating, but also to prevent serious injuries that can result from the impulse transmission from the projectile to the body.

The textiles are textile fabrics and consist e.g. from fabrics, nonwovens, knitwear or scrims based on raw materials such as aramid, polyamide, polyester, polyethylene, polypropylene or glass fibers. In addition to the starting materials, the type of manufacture and the structure have a significant influence on the properties of the textiles.

The protective properties * of the vest must be independent of external conditions, in particular, moisture or temperature must not reduce the protective effect. It should also be borne in mind that materials and constructions with a low basis weight are selected to achieve a high level of comfort. As a result, the problem of heat build-up, which occurs particularly in underwear vests, can be reduced. The protective vest should also be flame retardant.

It is known to be a laminate of layers of high-strength fabric Use fiber material to protect against ballistic effects. The individual layers are glued to one another over the entire area by a matrix material with which the fibers of the fabric are wetted. The disadvantage of such laminates is that they are relatively stiff and a shaping device is therefore required if they are to assume a predetermined shape.

From DE 100 11 701 AI a laminate for protection against ballistic effects is known, which consists of several layers of a fabric made of high-performance fibers, which are only connected in places, so that a flexible laminate results. In the production of the laminate, the individual fabric layers are first formed by weaving, laying or the like, whereupon the adhesive material is applied approximately at a point to the fabric surface by means of stencil application. The template has a hole diameter of 0.1 - 2 mm. After the fabric has been coated with adhesive at certain points, the individual layers are pressed together and then cut to the required shaped pieces. Aramid fibers, high-performance polyethylene and PWO fibers are used as high-performance fibers. In addition, the use of glass fibers for the laminate structure is also possible.

From GB-2 308 094 A a multi-layer flexible fabric material is known which, for. B. can consist of aramid fibers, a thermoplastic material formed as a network is arranged between the individual layers. The thermoplastic material of these nets is melted by heat and pressure treatment and thus leads to adhesion between the individual layers. These multi-layer materials are also used for the production of protective vests against ballistic effects.

Both the laminate from DE 100 11 701 AI and the multi-layer flexible fabric material from GB 2 308 094 A have the disadvantage that the individual layers of the multi-layer end fabric are bonded to one another at certain points, the individual adhesive areas being applied either by stencil application or by means of a network-like structuring always in the same areas arranged one above the other. This leads to only a limited flexibility of the end fabric.

The object of the invention is to provide a flexible protective textile in the form of a reinforcing composite which has a relatively low weight, an increased permeability to gases and / or liquids, as well as a higher resistance to ballistic loads and a higher flexibility, and which is also less expensive to manufacture. In addition, the reinforcement composite should be easily adaptable to specified loads in terms of production technology.

The object is achieved by a protective textile with the features of claim 1. Further advantageous embodiments of the invention are characterized in the subclaims.

Exemplary embodiments of the invention are explained in more detail with reference to the drawings. Show it:

Fig. 1 shows schematically an embodiment of a reinforcing composite according to the invention in cross section;

2 schematically shows an advantageous exemplary embodiment of a reinforcing composite in a top view;

Fig. 4 schematically shows a further embodiment of a reinforcing composite in cross section.

1 shows a flexible textile, laminated and / or laminated reinforcing composite 1 according to the invention, which is composed of individual textile layers 2. These textile Individual layers 2 are in each case connected to one another by means of an adhesive fleece 5 placed between two individual layers 2, forming local adhesive points 3 and non-adhesive contact surfaces 4 and / or cavities 7. Neither the local glue points 3 nor the non-adhesive contact surfaces 4 are systematically arranged, but distributed in a confused manner. The cross-sectional areas of the adhesive points 3 can also be different. Accordingly, the contact surfaces 4 are not arranged in the same area.

According to the invention, laminated laminates are thus used as textiles, the layers of which are connected to one another by discrete adhesive points, discrete cavities or contact surfaces being provided in addition to the adhesive points. The adhesives used are preferably somewhat elastic and / or flexible, so that loads do not lead directly to the breaking of the adhesive points. Preferably, such a distribution and configuration of the gluing points is also provided that mechanical, static and / or dynamic loads acting on an upper layer, which this layer cannot normally withstand, are partially transferred to the layer underneath via gluing points without the upper layer is damaged, the underlying layer absorbing the load without being released in a harmful manner to the surroundings of the installed textile. In this respect, the textile according to the invention has a high load absorption capacity.

Adhesive nonwovens are thin, very light, flexible fabrics with high elasticity made of thermoplastic, heat-activatable, dry adhesive fibers or adhesive monofilaments, which are in the form of thermally bonded, for example spinneret-extruded, nonwoven or extruded parallel nonwovens and which are, for example, wound up on a roll become. They can be based on different adhesive polymer bases, such as polyolefin, copolyamides, copolyethers and terpolymers. The Structure has many small gaps. Adhesive nonwovens are traded as web goods with basis weights of, for example, 10 to 100 g / m ² . For the bond ^• pressure, time and activation heat are required.

For the purposes of the invention, e.g. related to the application, the basis weight as well as the base polymer of the adhesive fleece are selected. Several layers of adhesive fleece of the same or different basis weights and / or the same or different polymer base can be selected between two layers of textile, so that the load absorption capacity can be controlled by the appropriate selection.

Likewise, the load absorption capacity of the textile can be specifically adjusted to the application by using adhesive fleeces of different basis weights and / or different polymer bases between several layers of the textile.

The adhesive fleece has synergistic effects for the textile laminate according to the invention. It ^'in the laminate a reversibly stretchable, resilient to almost elastic adhesive layer that does not impair the flexibility or softness of the fabric so that a textile according to the invention is guaranteed easy to handle. In addition, this adhesive has a very low weight and therefore does not burden the textile. '

In addition, however, an adhesive bond with a tangled nonwoven net structure is produced, which results from the adhesive bond of nonwoven elements to one another and the structural elements of the textile fabrics into which the adhesive penetrates, the nonwoven filament adhesive points resulting from the nonwoven filaments being the contact surfaces and / or cavities surround or surround. A large number of small dimensioned glue points that are randomly or irregularly distributed and also have different dimensions. The glue points essentially have the thread structure and thread length of the threads or thread portions which, during lamination or lamination, have produced the randomly distributed glue points by melting. These glue points are generally of different lengths and / or thicknesses and / or widths, so that an irregularity is also produced in this respect. It is attributed to these irregularities that the textiles produced with the adhesive fleeces guarantee a surprisingly high and superior load absorption capacity, which in particular may also result in a detectable high and superior delamination resistance.

In addition to the glue points, the cavities or contact surfaces are also distributed irregularly or confusingly and have correspondingly irregular dimensions. This cavity or surface contact structure also contributes decisively to the superior load absorption capacity, because this structure can buffer shock loads particularly effectively.

In combination with the targeted setting of the possibility of controlling the load absorption via the adhesive fleeces, the load absorption can also be controlled via different basis weights of the textile layers and / or the type of textile. In this respect, fabrics and / or knitted fabrics and / or scrims and / or nonwovens with the same or different basis weights and / or made of different materials, such as aramid, are expediently used. The use of the adhesive fleeces makes the combination of the textile layers of the textiles with non-textile functional fabrics such as metal foils, foams or the like particularly easy. These functional fabrics are also glued using adhesive fleeces. When using adhesive fleeces, the invention also makes it possible to control the load absorption in such a way that deliberate delamination of textile or non-textile individual layers can take place with absorption and derivation of occurring forces, without the textile as a whole losing its predefined functionality.

According to the invention, the local adhesive points 3 are for a high resistance to displacement and separation of the individual layers 2 and thus also for a high resistance of the reinforcing composite 1 according to the invention. B. responsible for pressure or pressure surge stress. In addition, the adhesive-free contact surfaces 4 enable gases and / or liquids to permeate through the reinforcing composite 1, and they also enable the composite 1 to have a high degree of softness and a low flexural strength.

This composite according to the invention of two or more individual textile layers is achieved by means of an adhesive fleece 5 each arranged between two individual textile layers.

2 schematically shows a laminate with an adhesive fleece 5, for which an adhesive fleece extruded by foaming is preferably used. The adhesive fleece 5 has a spider web-like structure made of polymeric filament parts 6 and cavities 7. The cavities 7 present in the structure of the adhesive nonwoven 5 lead to permeable contact surfaces 4 and cavities in the reinforcing composite 1. According to the invention it is provided that, when heat and pressure act on this arrangement of textile individual layers 2 and the adhesive fleece 5 arranged in between, the polymeric filament parts 6 of the adhesive fleece 5 melt and penetrate into the adjacent surfaces of the textile individual layers 2, as a result of which the sliding - And form permanent bond 3. The adhesive fleeces 5 consist of tangled filaments (Fig. 3). This unstructured distribution of the filaments 6 leads to the fact that, in the case of an arrangement of a plurality of textile individual layers 2 with adhesive fleece 5 in between, both the local adhesive spots 3 which form and the non-adhesive contact surfaces 4 are only randomly arranged one above the other. The likelihood that adhesive points 3 or adhesive-free contact surfaces 4 lying one above the other are arranged parallel to one another is very low due to the non-structured adhesive fleece 5. This random arrangement of the adhesive points 3 and the adhesive-free contact surfaces 4 and cavities 7 leads to increased flexibility in the multilayer end fabric, since the adhesive medium is not closed over the entire area like a film, but instead has small gaps.

4 shows a further embodiment of a reinforcement composite 1 with three textile individual layers 2 and adhesive fleece 5 arranged in between, the adhesive fleece 5 having a different number of adhesive joints 3, which results in a partially higher reinforcement and the depth of the reinforcement composite varies in flexibility receives.

The adhesive fleece 5 is based on an adhesive polymer. Polyolefins, copolyamides, copolyesters and terpolymers are used as polymers.

The adhesive nonwoven material can be produced as a sheet and has a basis weight of 10-100 g / m ² . The processing of these adhesive fleeces can take place continuously, ie from roll to roll, as well as discontinuously. The parameters pressure, time and heat are generally required for each bonding process in order to set the adhesive to the viscosity required for wetting. In addition, the adhesive medium can later be reactivated by heat and can bond with other substrates. The adhesive nonwovens 5 consisting of adhesive fibers or of adhesive monofilaments can be in the form of thermally bonded nonwoven fabrics which are extruded from the spinneret. Even with low adhesive weights, these adhesive fleeces 5 still have excellent separation strength without sticking over the entire surface and excellent permeability to gases and / or liquids. Furthermore, they are characterized by a flexible grip and high elasticity.

The following relationships exist between the properties of the adhesive fleece 5 and the structure and properties of the reinforcing composite 1:

Nonwoven reinforcement composite

Foam extrusion Softness Filament thickness Size and number of glue points Size and number of contact surfaces

Area mass size and number of glue points size and number of contact surfaces

It is also advantageous if the adhesive fleece has 30 to 300 adhesive-free contact areas 4 per cm ² .

To achieve special functional properties, e.g. on one or on both surface sides of the reinforcing composite 1 in the same operation as when bonding the individual textile individual layers 2 or in a subsequent operation also by means of an adhesive nonwoven functional surfaces such as B. metal foil, foam or the like.

The textile reinforcement composite 1 according to the invention enables light to meet the increasing functional requirements for high resistance to oblique to vertical pressure and puncture stress acting on a surface of the reinforcing composite 1 by the combination according to the invention of several textile individual layers, which are bonded to one another by small-area adhesive points and are resistant to sliding and separation.

By increasing the resistance to oblique to vertical superficial pressure or puncture stress due to the small-area, sliding and separable bond points, an application-related reduction in the total mass of the textile individual layers z. B. compared to comparable, by stacking individual layers with or without connection z. B. sewing possible. For the flexible textile reinforcement composite 1 according to the invention, this means a reduction in the material costs for the valuable individual textile layers and an increase in suitability for use due to the lower weight of the component or product made from the flexible textile reinforcement composite 1 that has to be clamped.

The invention is explained in more detail on the basis of exemplary embodiments, which, however, do not limit the invention.

Example 1:

In one embodiment, the flexible textile reinforcement composite 1 consists of three warp knitted textile individual layers 2 with a basis weight of 175, 250 and 400 g / m ² .

The warp knitted fabrics consist of polyester multifilament yarns. Is for connection between the warp with 175 g / m ² and 250 g / m ² basis weight, a polyester adhesive web 5 with a basis weight of 17 g / m ^2, and between the warp with 250 g / m ² basis weight and with 400 g / m ^{2 basis} weight Polyester adhesive fleece 5 with a basis weight of 24 g / m ² arranged. This multi-layer structure is fed to a flat bed laminating system and solidified there with the following conditions to form the reinforcing composite 1:

Temperature in the two adhesive joints: 132 ° C tape gap: 2.5 mm

For the test-technical representation of the high pressure and puncture resistance of the reinforcing composite 1, the stamp penetration force customary in geotextiles is determined. A cone-shaped metal stamp presses vertically through the surface of the clamped sample of the reinforcement composite at a constant speed.

With the construction listed in the exemplary embodiment, a punch penetration force of 12.45 kN was achieved. As a comparison, a stamp penetration force of 12.75 kN was used for a non-glued construction made of the same warp knitted fabrics made of polyester with a four-layer structure consisting of the basis weights 175 g / m ² , 200 g / m ² , 250 g / m ² and 400 g / m ² measured.

Example 2:

In a second embodiment, the flexible reinforcement composite 1 consists of 24 individual textile layers 2 of the same construction. Each is a woven fabric made of polyamide filament yarn with a basis weight of 60 g / m ² . For use, a polyamide adhesive fleece 5 extruded by foaming is used, the basis weight of the adhesive fleece 5, according to the invention, being varied as follows, starting from the surface side of the flexible reinforcing composite material 1 which is first subjected to impact pressure:

Between the first and sixth individual textile layers 2, 20 g / m ² ; Between the sixth and twelfth textile individual layers 2 40 g / m ² ;

Between the twelfth and twentieth textile layer 2, 60 g / m ² each;

Between the twentieth and the twenty-fourth individual textile layer 2, 80 g / m ^{2 in} each case.

The thermal bonding takes place on a flat bed laminating system in several passages in order to be able to economically achieve the temperature required for melting the adhesive nonwoven intermediate layers.

With such a construction according to the invention of the flexible textile reinforcement composite 1, the same puncture resistance is achieved as with a comparable laminate of 30 textile individual layers 2 made of the same polyamide fabric with a basis weight of 60 g / m ² , connected by sewing.

The adhesive fleece surface mass increasing with the number of individual textile layers 2 causes larger and more local adhesive sites 3 and thus a continuously increasing absorption of the energy of the penetrating body.

Example 3:

In a further exemplary embodiment, the flexible textile reinforcement composite 1 consists of five individual textile layers 2. In the middle of the reinforcement composite 1, a nonwoven fabric made of polyester fiber with a basis weight of 200 g / m ^{2 is} arranged.

On each of the two outer surfaces of the needle-punched nonwoven fabric, a fabric is used as the strength-bearing textile individual layer 2 Polyester monofilament yarn with a basis weight of 75 g / m ² arranged. A textile single layer 2 made of needle-punched nonwoven made of glass fibers with a mass per unit area of 160 g / m ^{2 is} arranged on the outer surfaces of these two fabrics, these two outer textile single layers 2 made of glass fiber nonwoven guarantee one. good flame resistance of the flexible textile reinforcement composite 1. These five textile individual layers 2 are connected to one another by adhesive fleeces 5 made of foamed polyester, each of which has a mass per unit area of 40 g / m ² .

According to the invention, the polyester needle-punched nonwoven fabric with the polyester fabrics with an adhesive nonwoven 5 with a mass per unit area of 40 g / m ² and the polyester fabric with the glass fiber nonwovens is in each case provided with two nonwoven webs 5 with a mass per unit area of 20 g / m ² , i.e. a total adhesive nonwoven mass of 40 g / m ² connected. According to FIG. 4, the local adhesive points 3a and 3b are produced, the number of adhesive points 3b formed from two layers of adhesive nonwoven having the same total mass being present. Here, in all textile individual layers 2 of the reinforcing composite 1, despite different polymers of the individual layers, approximately the same separation resistance is guaranteed.

Example 4:

In a further exemplary embodiment, the flexible textile reinforcement composite 1 consists of three textile individual layers 2 of the same construction. Each is a fabric made of aramid filament yarn with a basis weight of 200 g / m ² . A polyamide adhesive fleece 5 extruded by foaming is used for the connection, the basis weight of the adhesive fleece in the laminate, in each case between the individual layers, being 60 g / m ² . The thermal Solidification takes place on a flat bed laminating machine with the fixing conditions required by the adhesive system.

Eight of these "3-layer laminates" showed the same and better puncture resistance as 30 textile single layers made of the same material and the same construction.
