Abstract
The present invention provides an improved fabric which comprises at least one network of fibers selected from the group consisting of extended chain polyethylene (ECPE) extended chain polypropylene (ECPP) fibers, extended chain polyvinyl alcohol fibers and extended chain polyacrylonitrile fibers. A low modulus elastomeric material, which has a tensile modulus of less than about 6,000 psi, measured at about 23° C., substantially coats the fibers of the network. Preferably, the fibers have a tensile modulus of at least about 500 grams/denier and an energy-to-break of at least about 22 Joules/gram.
