This report describes the addition of deodorizing functionality to wool fibers by chemical modification for recycling used wool into a functional fiber material. Wool fibers were oxidized and succinylated and the effects of these treatments on ammonia sorption were evaluated. Oxidation significantly improved the ammonia sorption of wool fibers. The oxidized wool fibers also considerably sorbed methyl amine and dimethyl amine, though butyl amine and trimethyl amine were poorly sorbed. Ammonia sorbed rapidly with sulfuric acid groups but sorbed more slowly with carboxylic groups in oxidized and succinylated wool fibers. The sorbability of oxidized wool fibers after repeated sorption could be completely restored by washing with 0.5mM sulfuric acid.
