Abstract
A dyed synthetic fiber having antibacterial and antifungal properties is described, which contains 0.01 to 20 weight % of a silver-substituted zeolite and 0.001 to 1.0 weight % of a substantially water-insoluble copper compound. The copper compound is present independent of zeolite particles in the fiber. The dyed synthetic fiber is prepared by incorporating a silver-substituted zeolite in a monomer or a polymerization mixture before the completion of polymerization in the step of preparing a polymer for the fiber; further incorporating the copper compound in the polymer before the spinning thereof into a fiber; spinning the polymer into a fiber; and dyeing the fiber. The dyed fiber retains a high level of antibacterial and antifungal properties.
