Abstract
Puncture-resistant fabric layers such as a fabric layer with a high cover factor woven fabric having a fill yarn cover factor of at least about 75% of full and a warp yarn cover factor of at least about 100% of full formed of fill yarns and warp yarns, wherein the weight per unit length of the fill yarns is less than the weight per unit length of the warp yarns. Some embodiments have high tenacity fibers having a tensile breaking strength of at least about 10 g/Denier. Techniques for forming light weight yarns with high tenacity fibers for the small fill yarns and/or warp yarns. The high cover factor, small fill yarn-constructed woven fabrics can have natural and/or synthetic fibers with a tensile breaking strength less than about 10 g/Denier.
