Claims43
An absorbent sanitary article for absorbing body fluids which comprises a fibrous matrix including at least one fiber having an outer surface and metallic silver attached to the outer surface, the silver having a metallic silver surface area, attachment of the silver to the outer surface consisting essentially of chemical and/or physical bonds other than bonds formed by liquid matrix or dispersing media for the silver, whereby the silver is immobilized relative to the fiber surface so that the metallic silver surface area is accessible to the body fluids and the silver cannot be flushed away from the fiber during use of the sanitary article.
An absorbent sanitary article for absorbing body fluids comprising a fibrous matrix including at least one fiber having an outer surface, metallic silver bonded to the outer surface by bonds that are free of liquid matrix or dispersing media for the silver, the silver having a metallic silver surface area, whereby the metallic silver surface area is accessible to the body fluids and the silver cannot be flushed away from the outer surface during use of the sanitary article.
A process for producing an absorbent sanitary article for absorbing body fluids which comprises a fibrous matrix containing metallic silver having a metallic silver surface area, comprising the steps of disposing a fiber having an outer surface in said matrix, attaching the silver to the outer surface with bonds consisting essentially of chemical and/or physical bonds other than bonds formed by liquid matrix or dispersing media for the silver, and thereby immobilizing the silver relative to the outer surface of the fiber so that the metallic silver surface area is accessible to the body fluids and the metallic silver cannot be flushed away from the outer surface during use of the sanitary article.
A process for producing an absorbent sanitary article for absorbing body fluids which comprises a fibrous matrix containing metallic silver having a metallic silver surface area, comprising the steps of disposing a fiber having an outer surface in said matrix and binding said metallic silver exclusively to said fiber surface to immobilize the metallic silver relative to the surface of the fiber so that the metallic silver surface area is accessible to the body fluids and the metallic silver cannot be flushed away from the fiber surface during use of the sanitary article.
