<p>The invention relates to a penetration inhibiting material. The material comprises at least one layer of thickness D and this layer, in turn, has a first and a second woven ply. The first and second woven plies are joined using a binding agent. The first woven ply comprises a first set of threads, which accounts for at least 65% of the weight of the woven, and which has a thread density ranging from 3.5 to 30 threads/cm, a thread titer of at least 210 dtex, and filaments, which form the threads and which have a filament diameter F1. The first woven ply also comprises a second set of threads, which has a thread density ranging from 0.5 to 16 threads/cm and a thread titer of at least one 50 dtex. The second set of threads runs at an angle of greater than 0 DEGREE to 90 DEGREE with regard to the first set of threads, and the ratio of the thread density of the first set of threads to the thread density of the second set of threads is greater than 1. The second woven ply comprises a first set of threads, which has a thread density ranging from 0.5 to 16 threads/cm and a thread titer of at least 50 dtex, and comprises a second set of threads, which accounts for 65% of the weight of the woven and which has a thread density ranging from 3,5 to 20 threads/cm, a thread titer of at least 210 dtex, and filaments, which form the threads and which have a filament diameter F2. The second set of threads runs at an angle of greater than 0 DEGREE to 90 DEGREE with regard to the first set of threads, and the ratio of the thread density of the second set of threads to the thread density of the first set of threads is greater than 1. The first and second set of threads of the first woven ply runs parallel to the first set or second set of threads of the second woven ply, and the ratio of D/F1 and D/F2 is equal to a value ranging from 14.5 to 40.</p> |
