Abstract
A composite fabric, multi-layer protective panel alternative to an exclusively fine denier, continuous filament yarn protective fabric, multi-layer protective panel. Fabric layers consist of warp and fill sheets of continuous filament yarn of relatively higher denier at a relatively lower cover factor that have their yarns interlocked in a woven pattern by overlapping warp and fill sheets of staple yarns of relatively lower denier, thus raising effective cover factor. Staple yarns have a conspicuous amount of hairiness for greater yarn stability. Ballistic performance is enhanced by depositing a molten mass of fiber material and protruding staple fiber filament ends on a striking projectile upon impact on outer layers, and transporting the additional mass into the panel with a higher coefficient of friction.
