ABSTRACT:
A modified fibrous material comprising cellulose fibers substituted at their cellulose anhydroglucose units by anionic moieties of at least one of the formulae: --PO.sub.3 H.sup.(-) ; --(CH.sub.2).sub.n -PO.sub.3 H.sup.(-) ; --(CH.sub.2).sub.n -SO.sub.3.sup.(-) ; or (CH.sub.2).sub.n --COO.sup.(-) ; where n is from 1 to 3; and capped by copper cations to the extent that said cellulose fibers bind from about 0.1 to about 3.0% by weight of copper, based on the weight of said fibers; as well as processes for its production.
