Abstract
The invention covers a method of forming functionally active fibers and substrates including functionally active fibers. The method includes forming a mixture of at least one poly vinyl polymer and at least one bleaching active. The mixture is then injected at a controlled flow rate into an electric field to cause the mixture to at least partially form fine fibers that have an average diameter of less than about 1000 nanometers.
