ABSTRACT:
A multilayer composite fabric material consisting of a woven or non-woven fabric support, a microporous membrane layer, and an ultrathin permselective surface coating, and optionally an intermediate sealing layer and a protective top layer; the material being freely permeable to water vapor but impermeable to toxic organic vapors.
The material is suitable for fabricating protective clothing for use in industrial and military hazardous chemical enviornments.
