Embodiment Construction

[0040] example

[0041] A penetration barrier material containing 22 double layers was produced using the following procedure.

[0042] Produced with Teijin Twaron in warp 930 dtex (9.5 threads / cm, with Ciba OLE OPHOBOL from Pfersee GmbH, Langwied am Lech, DE treated to produce water resistance), polyester 140 dtex (produced by Hoechst) is used in the weft direction 710) (2 threads / cm), making the first layer of each double layer.

[0043] Use polyester 140 decitex (produced by Hoechst) in the warp direction 710) (4 threads / cm) and produced with Teijin Twaron in the weft direction 930 dtex (9.5 threads / cm, with Ciba OLEOPHOBOL from Pfersee GmbH, Langwied am Lech, DE treatment creates water resistance), making the second layer of each double layer. The warp / longitude ratio of the first layer to the weft / longitude ratio of the second layer is 6.6.

[0044] To prepare a double layer, the first and second layers were laminated together with 3 layers of polyethylen...

Abstract

A penetration-resistant material is described comprising at least a double layer of wowen fabric wherein the double layer comprises a first layer of fabric composed of a first set of threads comprising 3.5 to 20 threads / cm, having a linear density of at least 210 dtex, and comprising at least 65 % of the fabric weight, and a second set of threads comprising 0.5 to 16 threads / cm and having a linear density of at least 50 dtex, with the second set of threads being transverse to the first set of threads, and the ratio of the number of threads / cm of the first set to that of the second set is > 1, and a second layer of fabric composed of a first set of threads comprising 0.5 to 16 threads / cm and having a linear density of at least 50 dtex, and a second set of threads comprising 3.5 to 20 threads / cm, having a linear density of at least 210 dtex, and comprising at least 65 % of the fabric weight, with the second set of threads being transverse to the first set of threads, and the ratio of the number of threads / cm of the second set to that of the first set is > 1, and wherein the first and second sets of threads of the first layer have a parallel orientation towards the first and second sets, respectively, of threads of the second layer, and wherein in the first layer of fabric at least the first set of threads and in the second layer of fabric at least the second set of threads are treated with a water-repellant.

Description

technical field [0001] The present invention relates to a penetration resistant material and to articles made therefrom. Background technique [0002] Penetration resistant articles such as bulletproof vests, helmets, vehicle panels and armor made from high strength fibers are well known in the art. For many applications, especially for ballistic (ballistic) vests, these fibers are used in woven or knitted fabrics. The fabric can be coated or impregnated in a matrix to obtain a hard ballistic resistant material, or it can be used without a matrix to obtain a soft ballistic resistant material. [0003] A ballistic resistant fabric is known especially from EP 310199 . The fabric disclosed herein is composed of high-strength, high-modulus, ultra-high molecular weight polymer filament yarns, and the warp threads are made of a different polymer material than the weft threads. [0004] In the former Soviet Union patent RU2096542, a bulletproof fabric for bulletproof jackets is ...
