Abstract
Abstract A material suitable for fabricating chemical warfare protective garments comprises at least one layer of an activated woven carbon fabric plus a body-side high absorbency rayon layer interposed between said at least one woven carbon fabric layer and the wearer's body. An innermost body-side layer of a ribbed fabric such as corduroy underlays the carbon and rayon layers to channel vapor away from the material. Chemical warfare protective garments having extended use life can be fabricated from this material.
