Abstract
Abstract A method for absorbing bodily secretions while hindering the generation of odors and growth of microbes comprising applying a fibrous mass having copper cations bound through selected anions, preferably carboxymethyl, the amount of chemically bound copper being between 0.1 and 3% by weight. The fibrous mass can be in the form of a catamenial device, bandage, diaper, shoe liner, or the like.

Claim 1
Independent Claim
147 words
A method for absorbing bodily secretions while hindering the generation of odors and growth of microbes comprising applying to said secretions at or near their source, an effective amount of a fibrous material consisting at least partially of viscose cellulose fibers substituted uniformly by anionic moieties of at least one of the general formulae: --PO 3 H.sup.(-) ; --(CH 2 ) n --PO 3 H.sup.(-) ; --(CH 2 ) n --SO 3 .sup.(-) ; or --(CH 2 ) n --COO.sup.(-) ; wherein n is from 1 to 3; which anionic moieties are each attached through an oxygen atom to a viscose cellulose anhydroglucose unit; wherein sufficient of said anionic moieties are present, and sufficient of said present anionic moieties are bonded to cupric cations, that said viscose cellulose fibers bind from about 0.1 to about 3% by weight of copper, based on the weight of said fibers.
Claim 2
Independent Claim
147 words
