ABSTRACT:
A process for preparing a moisture exchange element which comprises impregnating a substrate made of organic or inorganic fiber with an aqueous impregnating solution containing colloidal silica, an acid and a metallic cation; drying and gelatinizing the impregnating solution deposited on the impregnated substrate is disclosed. The absorbent formed on the substrate after the impregnating solution is dried has a pore size of about 60-70 .ANG., thus allowing the moisture exchange element of the present invention to provide improved moisture adsorbing/desorbing ability.
