Penetration-resistant textile fabrics and articles comprising said fabrics

Abstract

Penetration-resistant textile fabrics and articles that include the fabrics. The penetration-resistant textile fabrics have improved fragment protection and improved stab resistance efficiency at the same ballistic protection. The advantageous combination of characteristics of the penetration-resistant textile fabrics correspondingly transfers to articles that include the penetration-resistant textile fabrics.

1 . A penetration-resistant textile fabric comprising at least one untwisted high-performance filament yarn selected from the group consisting of aramid filament yarns, polybenzoxazole filament yarns, polybenzothiazole filament yarns, and mixtures of the filament yarns, wherein:
 the at least one untwisted high-performance filament yarn has a breaking tenacity of at least 1100 MPa, measured without twist according to ASTM D-885, and   the at least one untwisted high-performance filament yarn is a volumized high-performance filament yarn to the extent that the textile fabric (I) which comprises the volumized high-performance filament yarn has a relative compressibility, measured according to DIN 53885, determined by measuring the initial thickness at a measuring pressure of 0.5 N/cm 2  and the end thickness at a measuring pressure of 5 N/cm 2 , wherein-the relative compressibility ie-being greater by a factor off, which has a value in the range of 1.2 to 5, than the-a relative compressibility of a textile comparison fabric, the production of which differs from the production of the penetration-resistant textile fabric in that the high-performance filament yarn of the textile comparison fabric is not volumized.   
     
     
         2 . (canceled) 
     
     
         3 . The penetration-resistant textile fabric according to  claim 1 , wherein the textile fabric is a woven fabric, a knitted fabric, or a unidirectional or multiaxial composite. 
     
     
         4 . The penetration-resistant textile fabric according to  claim 1 , wherein the volumized high-performance filament yarn comprises high-performance filaments and shrunken filaments. 
     
     
         5 . The penetration-resistant textile fabric according  claim 1 , wherein the volumized high-performance filament yarn is a texturized high-performance filament yarn. 
     
     
         6 . The penetration-resistant textile fabric according to  claim 5 , wherein the texturized high-performance filament yarn is a knit-de-knit texturized high-performance filament yarn. 
     
     
         7 . The penetration-resistant textile fabric according to  claim 1 , wherein the factor f has a value in the range from 1.4 to 4. 
     
     
         8 . An article comprising at least one penetration-resistant textile fabric according to  claim 1 . 
     
     
         9 . The article according to  claim 8 , wherein the article is:
 i) selected from the group consisting of a helmet, a vehicle armor, or and a ceramic composite plate, or   ii) selected from the group consisting of a fragment protection mat, a bullet-proof vest, a flak jacket, a stab-resistant vest, and combinations thereof. cm  10 - 16 . (canceled)
