Abstract

Garments made from a composite, protective fabric are disclosed. The composite fabric has microflex layers of woven para-aramid yarn placed in proximity to metallic mesh layers of woven stainless steel mesh. The individual poly-p-phenylene terephthalamide fibers in the para-aramid yarn have a denier of less than or equal to 2 dtex. The metallic mesh layers are woven from stainless steel fibers having a diameter of 0.2 mm or less and have a mesh aperture of 0.45 mm or less. The garments made using the fabric include gloves, bullet proof vests and chain-saw resistant trousers.
