The disclosed subject matter relates to chemical and biological protective garments and ensembles (i.e., two-part garments that when worn together cover most of the human body) and composite fabrics used therein. The composite fabrics include embodiments having a fabric cover layer combined with a vapor protective layer.

Chemical and biological thermal ensemble and composite fabric

The present invention relates to a textile composite for the adsorption and breakdown of harmful chemical materials. A support layer and a sorptive and reactive material mounted on the support layer form a protective layer, which is mounted on an inner liner. The protective layer adsorbs and breaks down harmful chemical materials. An outer shell is formed of fabric having an outer surface that is hydrophobic for resisting the passage of harmful chemicals, which may be in the form of vapor, liquid or aerosols. Preferably, the sorptive and reactive material includes zirconium hydroxide, and the support layer includes a fabric material. The zirconium hydroxide is distributed on the fabric material in the amount of at least 20 grams of zirconium hydroxide per square meter. Alternatively, the zirconium hydroxide is distributed in the amount of at least 150 or 200 grams of zirconium hydroxide per square meter.
