Abstract

The present invention provides an antimicrobial fabric comprising a fibrous material treated with an antimicrobially effective amount of an antimicrobial agent. The present invention further provides a method for preparing an antimicrobial fabric that exhibits antimicrobial properties comprising admixing an antimicrobially effective amount of an antimicrobial agent with a fibrous material.

Claims

1. An antimicrobial fabric comprising a fibrous material treated with an antimicrobially effective amount of an antimicrobial agent.

2. The antimicrobial fabric according to claim 1, wherein the fibrous material is a woven or a non-woven material.

3. The antimicrobial fabric according to claim 1, wherein the fibrous material is a disposable or a non-disposable material.

4. The antimicrobial fabric according to claim 1, wherein the fibrous material is a natural fiber selected from the group consisting of cotton, wool, silk, flax, mohair, linen, hemp, ramie, and jute.

5. The antimicrobial fabric according to claim 1, wherein the fibrous material is a non-natural fiber selected from the group consisting of rayons, acetates, nylons, polyesters, polyolefins, polyamides, acrylics, modacrylics fibers, fluorocarbons, glass fibers, and spandex.

6. The antimicrobial fabric according to claim 1, wherein the antimicrobial agent is selected from the group consisting of anti-viral agents, antibacterial agents, antimycotic agents, and combinations thereof.

7. The antimicrobial fabric according to claim 6, wherein the anti-viral agent is selected from the group consisting of acyclovir, foscarnet sodium, ribavirin, vidarabine, ganeiclovir sodium, zidovudine, phenol, amantadine hydrochloride, and interferon alfa-n3.

8. The antimicrobial fabric according to claim 6, wherein the antibacterial agent is selected from the group consisting of bismuth containing compounds, sulfonamides, nitrofurans, metronidazole, tinidazole, nimorazole, benzoic acid, aminoglycosides, macrolides, penicillins, polypeptides, tetracyclines, cephalosporins, chloramphenicol, and clidamycin.

9. The antimicrobial fabric according to claim 6, wherein the antimycotic agent is selected from the group consisting of heavy-metal fungicides, quinones, dithiocarbamates, imidazolines, guanidines, trichloromethylthiocarboximides, chlorinated and nitrated benzenes, (N-(trichloromethylthio)-4-cyclohexene-1,2-dicarboximide), (N-(trichloromethylthio)-phthalimide), oxathiins, benzimidazoles, pyrimidines, and partially halogenated hydantoins.

10. The antimicrobial fabric according to claim 1, wherein the antimicrobial agent is aluminum chlorohydrate, an aluminum chlorohydrate-containing compound, or an equivalent thereof.

11. The antimicrobial fabric according to claim 10, wherein the antimicrobial agent is selected from the group consisting of aluminum chlorohydrate, aluminum sesquicholorhydrate, aluminum dichlorohydrate, aluminum zirconium octachlorohydrate, aluminum zirconium pentachlorohydrate, aluminum zirconium tetrachlorohydrate, and aluminum zirconium trichlorohydrate.

12. The antimicrobial fabric according to claim 11, wherein the antimicrobial agent is aluminum chlorohydrate.

13. The antimicrobial fabric according to claim 1, wherein the antimicrobial agent is an antimicrobial copper salt.

14. The antimicrobial fabric according to claim 13, wherein the antimicrobial agent is selected from the group consisting of cupric sulfate, cupric acetate, copper carbonate basic, cupric hydroxide, cuprous iodide, cupric oxide, cuprous oxide, and cupric chloride.

15. The antimicrobial fabric according to claim 14, wherein the antimicrobial agent is cupric sulfate.

16. The antimicrobial fabric according to claim 1, wherein the antimicrobial fabric is a medical fabric selected from the group consisting of surgical gowns, scrubs, tabards, gloves, socks, hats, belts, shoes, insoles for shoes, padding, bandages, draping, sheeting, pillow cases, towels, and rugs.

17. The antimicrobial fabric according to claim 1, wherein the antimicrobial agent also acts as an indicator to distinguish between fibrous material treated with the antimicrobial agent and fibrous material untreated with the antimicrobial agent.

18. The antimicrobial fabric according to claim 1, wherein the fibrous material treated with the antimicrobial agent is distinguishable from fibrous material untreated with an antimicrobial agent by addition of an indicator to show treatment.

19. A method for preparing an antimicrobial fabric that exhibits antimicrobial properties comprising admixing an antimicrobially effective amount of an antimicrobial agent with a fibrous material.

20. The method according to claim 19, wherein the fibrous material is a woven or a non-woven material or a disposable or a non-disposable material.

21. The method according to claim 19, wherein the fibrous material is a natural fiber selected from the group consisting of cotton, wool, silk, flax, mohair, linen, hemp, ramie, and jute.

22. The method according to claim 19, wherein the fibrous material is a non-natural fiber selected from the group consisting of rayons, acetates, nylons, polyesters, polyolefins, polyamides, acrylics, modacrylics fibers, fluorocarbons, glass fibers, and spandex.

23. The method according to claim 19, wherein the antimicrobial agent is selected from the group consisting of anti-viral agents, antibacterial agents, and antimycotic agents.

24. The method according to claim 19, wherein the antimicrobial agent is aluminum chlorohydrate, an aluminum chlorohydrate-containing compound, or an equivalent thereof.

25. The method according to claim 24, wherein the antimicrobial agent is selected from the group consisting of aluminum chlorohydrate, aluminum sesquicholorhydrate, aluminum dichlorohydrate, aluminum zirconium octachlorohydrate, aluminum zirconium pentachlorohydrate, aluminum zirconium tetrachlorohydrate, and aluminum zirconium trichlorohydrate.

26. The method according to claim 25, wherein the antimicrobial agent is aluminum chlorohydrate.

27. The method according to claim 19, wherein the antimicrobial agent is an antimicrobial copper salt.

28. The method according to claim 27, wherein the antimicrobial agent is selected from the group consisting of cupric sulfate, cupric acetate, copper carbonate basic, cupric hydroxide, cuprous iodide, cupric oxide, cuprous oxide, and cupric chloride.

29. The method according to claim 28, wherein the antimicrobial agent is cupric sulfate.

30. The method according to claim 19, wherein the antimicrobial fabric is a medical fabric selected from the group consisting of surgical gowns, scrubs, tabards, gloves, socks, hats, belts, shoes, insoles for shoes, padding, bandages, draping, sheeting, pillow cases, towels, and rugs.

31. The method according to claim 19, wherein the antimicrobial agent also acts as an indicator to distinguish between fibrous material treated with the antimicrobial agent and fibrous material untreated with the antimicrobial agent.
