1. A method of treating fibers to render the fibers antibacterial, said method comprising the steps of:
- a) preparing a solution containing monovalent copper cations;
b) immersing said fibers in said solution for a period of time sufficient for adsorption of said copper cations;
c) at the same time or subsequently, treating said fibers in a solution containing anions wherein said anions are selected from the group consisting of borate, carbonate and mixtures thereof for period of time sufficient for adsorption of said anions;
d) removing said copper containing fibers from the solution containing anions.
