Claims
- 1. A method for obtaining a desired antimicrobial agent concentration in a fiber while passing said fiber through a liquid medium, comprising:
- providing a fiber containing an initial concentration of the antimicrobial agent 4,5-dichloro-2-cyclohexyl-3-isothiazolone that is essentially homogenously distributed throughout the fiber cross-section;
- passing said fiber through a liquid medium which contains the same antimicrobial agent that is contained in said fiber, said antimicrobial agent in said liquid medium being controlled in a concentration relative to the initial concentration in said fiber whereby a desired, predetermined antimicrobial concentration in said fiber following its passage through said liquid medium is obtained.
- 2. The method of claim 1 wherein:
- the medium contains a concentration of antimicrobial agent sufficient to result in essentially no change in the antimicrobial agent concentration of the fiber.
- 3. The method of claim 1, wherein:
- the medium contains a concentration of antimicrobial agent sufficient to result in an increase in the antimicrobial agent concentration of the fiber.
- 4. The method of claim 1, wherein:
- the medium contains a concentration of antimicrobial agent sufficient to result in a decrease in the antimicrobial agent concentration of the fiber.
- 5. The method of claim 1, wherein:
- said medium is an aqueous medium.
- 6. The method of claim 1, wherein said fiber is nylon.
- 7. The method of claim 1, wherein:
- said aqueous medium also functions to dye the fiber during passage through the medium.
- 8. The method of claim 7, wherein:
- said medium is a beck dye bath.
- 9. A product produced by the method of claim 1.
