- Suitable polymers are rigid PVC with a flexural modulus between 3500 and 4000 MPa or polyurethanes with a flexural modulus between 4000 and 4500 MPa.
- Polymer films made from a polycarbonate have proven particularly useful for connecting the fabrics to form a fabric layer.
- a polycarbonate is sold, for example, under the name POKALON N 38 by Color Print (Frankenthal, Germany).
- Another example of a suitable polycarbonate is the polycarbonate sold under the name LEXAN 103 by GE Plastics.
- LEXAN 103 has a flexural modulus of 2500 MPa, a strength of 70 MPa and an elongation at break of 120%.
- protective clothing according to the invention which comprises a protective material which consists of an arrangement of a plurality of fabric layers lying one on top of the other and a layer of felt is placed on both the outer surface and the inner surface, shows particularly good protection. Therefore, this embodiment is preferred, in particular when the protective material comprises an arrangement of 6 to 30 layers of fabric lying one on top of the other, and it is particularly preferred from the point of view of protective effect and wearing comfort if the protective material comprises an arrangement of 6 to 25 layers of fabric lying on top of one another.
- a further preferred embodiment of the present invention consists in protective clothing which comprises at least two of the protective materials as described above.
- a protective material or a plurality or all or all of the protective materials are preferably arranged in a cover made of textile material in the protective clothing according to the invention, because this provides better handling.

- the protective effect is illustrated by the stab protection effect which protective materials of the protective clothing according to the invention show.
- the stab protection effect was tested according to the NU (National Institute of Justice) - Standard - 0115.00, protection class KR 2. To do this, drop a skewer with a drop device onto the stab protection material.
- the stab protection material is fixed with a tension belt on a background material, which consists of different foams defined in the standard mentioned.
- the spit falls on the stab protection material, penetrates the material and penetrates a certain distance into the background material.
- the penetration into the background material is measured in mm and the arithmetic mean is determined from several drop tests. In a modification of the above-mentioned standard, this mean value is referred to as puncture resistance.
- Fabrics were made from aramid yarns with a titer of 930 dtex and a breaking strength of 3380 MPa in plain weave. The warp and weft contained approximately the same number of threads.
- the Walz fabric density was 18.5%, the fabric weight 140 g / m 2 .
- a polymer film made of polycarbonate (POKA-LON N 38, company Color Print, Frankenthal, Germany) with a weight per unit area of 75 g / m 2 was placed between two fabrics which had been washed beforehand. The two fabrics were laminated with the polymer film to form a fabric layer in a temperature range between 220 and 230 ° C. at a pressure of about 100 bar.
- Example 1 16 of the above Lay layers of fabric on top of each other, fasten them to the background material with a tension belt and measure the puncture resistance as described above.
- Example 2 16 layers of felt were placed on top of one another, fastened to the background material with a tension belt and the puncture resistance measured as described above.
