Ballistic Fabric

Abstract

Briefly the invention relates to a flexible fabric for use as for example in a roll-up shutter with improved ballistic properties. More specifically, the present invention is directed to a ballistic fabric that is formed from a unique cabled yarn and allows less deformation on impact. The unique cabled yarn may be a metal reinforced aramid yarn for giving the fabric additional strength.

1 . A ballistic fabric for use in a roll-up shutter or the like, the fabric comprising:
 a plurality of cabled yarns in MD and CD directions;   
     wherein said cabled yarns are formed by cabling high tenacity aramid yarns with metal. 
   
   
       2 . A method for producing a ballistic fabric, the method comprising the steps of:
 cabling high tenacity aramid yarns with metal; and   weaving said cabled yarns in a preferred pattern to a predetermined width.   
   
   
       3 . A ballistic fabric for use in a roll-up shutter or the like, the fabric comprising:
 a plurality of composite yarns in MD and CD directions;   
     wherein said composite yarns are formed from aramid strands used as a core material within a thermoplastic sheath. 
   
   
       4 . A method for producing a ballistic fabric, the method comprising the steps of:
 producing composite yarns with aramid strands used as a core material within a thermoplastic sheath; and   weaving said composite yarns in a preferred pattern to a predetermined width.   
   
   
       5 . The fabric according to  claim 1 , wherein said yarns are UV coated for outdoor exposure of said fabric. 
   
   
       6 . The fabric according to  claim 1 , wherein the metal is stainless steel.
