  • Microbistatic and deodorizing catamenial and hygienic devices
    Patent number: 4675014
    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.
    Type: Grant
    Filed: March 4, 1985
    Date of Patent: June 23, 1987

  • Copper-modified carboxyalkyl-cellulose fiber
    Patent number: 4637820
    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.
