Abstract
Abstract A pad for protecting at least a portion of the human body against injury including at least three hybrid fabric layers, each hybrid fabric layer comprising at least one high strength fiber having a tensile modulus of at least about 160 grams/denier and a tenacity of at least about 7 grams/denier and at least one ground fiber, wherein the hybrid fabric layer has a construction selected from the group consisting of a weft knit of the high strength fiber and the ground fiber, a warp knit of the high strength fiber and the ground fiber, an inserted warp knit wherein the high strength fiber is inserted into a warp knit of the ground fiber, and a stitchbonded knit.
