  • Penetration-resistant material comprising fabric with high linear density ratio of two sets of threads
    Patent number: 7132380
    Abstract: A penetration-resistant material having at least a double layer of woven fabric having a first layer of fabric composed of a first set of threads having 3.5 to 20 threads/cm, a linear density of at least 210 dtex, and at least 65% of the fabric weight, and a second set of threads having 0.5 to 16 threads/cm and a linear density of at least 50 dtex and a second layer of fabric composed of a first set of threads having 0.5 to 16 threads/cm and a linear density of at least 50 dtex, and a second set of threads having 3.5 to 20 threads/cm, a linear density of at least 210 dtex, and at least 65% of the fabric weight. In each layer, the second set are transverse to the first set and the ratio of the number of threads/cm of the second set to that of the first set is >1.

  • Penetration-resistant material comprising fabric with high linear density ratio of two sets of threads
    Publication number: 20040082242
    Abstract: The invention pertains to a penetration-resistant material comprising at least a double layer of woven fabric, characterized in that 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.

  • Penetration-resistant material comprising fabric with high linear density ratio of two sets of threads
    Patent number: 6610618
    Abstract: The invention pertains to a penetration-resistant material having at least a double layer of fabric composed of two layers of woven fabric which are cross-plied at an angle, characterized in that the fabric is composed of a first set of threads having 3.5 to 20 threads/cm and having a linear density of at least 420 dtex, and a second set of threads having 0.5 to 8 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 wherein the ratio of the linear density of the first set of threads to the linear density of the second set of threads is >4.2, more preferably >7.5. In a preferred embodiment, the first set of threads is warp threads made of p-aramid yarn and the second set of threads is weft threads of polyester yarn, and the ratio of the number of threads/cm of the first set to that of the second set is >1.
