Abstract

Antimicrobial and/or anti-odor textile coating composition that reduce and/or prevent bacterial growth and/or control odor(s) on a textile material treated for a prolonged time period including up to, for example, fifty wash cycles. The textile coating compositions may include benzoic acid and at least one of terephthalic acid, and/or a quat silane.

Claims (27)

1. An antimicrobial and/or anti-odor, textile coating composition that reduces and/or prevents microbial growth and/or controls odor(s) on a textile material comprising:

(a) from 65 weight % to 90 weight % benzoic acid, based on the total weight of the composition; and

(b) terephthalic acid;

wherein the benzoic acid and the terephthalic acid are present in the composition at a ratio of 2:1 to 8:1.

2. The antimicrobial and/or anti-odor, textile coating composition according to claim 1 , wherein the benzoic acid is present from 75 weight % to 85 weight % of the total weight of the composition.

3. The antimicrobial and/or anti-odor, textile coating composition according to claim 1 , wherein the terephthalic acid is present from 10 weight % to 35 weight % of the total weight of the composition.

4. The antimicrobial and/or anti-odor, textile coating composition according to claim 1 , wherein the terephthalic acid is present from 15 weight % to 20 weight % of the total weight of the composition.

5. A textile material having the antimicrobial and/or anti-odor, textile coating composition according to claim 1 applied thereon, wherein the textile material reduces bacterial growth by a 3 log reduction or greater when compared with an untreated textile material.

6. The textile material according to claim 5 , wherein benzoic acid forms an outermost layer and terephthalic acid forms an intermediary layer positioned between the benzoic acid and the textile material having the textile coating composition applied thereon.

7. The textile material according to claim 5 , wherein the textile material reduces bacterial growth by a 3 log reduction or greater after twenty-five home launderings when compared with an untreated textile material.

8. The textile material according to claim 5 , wherein the textile material comprises polyester.

9. The textile material according to claim 5 , wherein the antimicrobial and/or anti-odor, textile coating composition is present on the textile from 2 weight % to 10 weight % on weight of fabric.

10. The textile material according to claim 5 , wherein the textile material comprises benzoic acid from 1.3 weight % to 9 weight % based on weight of fabric.

11. The textile material according to claim 5 , wherein the textile material comprises terephthalic acid from 0.2 weight % to 3.5 weight % based on weight of fabric.

12. A method of reducing and/or preventing microbial growth and/or odor on a textile material, the method comprising:

a. applying the antimicrobial and/or anti-odor, textile coating composition according to claim 1 to a textile material;

wherein, applying the antimicrobial and/or anti-odor, textile coating composition comprises padding or exhaustion of the composition onto the textile material to obtain a treated textile material that resists the growth of microbes and controls odor on the textile for a prolonged period of time.

13. The method according to claim 12 , further comprising, prior to step (a), adding the antimicrobial and/or anti-odor, textile coating composition according to claim 1 to water to create an application bath.

14. The method according to claim 13 , further comprising adding a dispersant to the application bath, heating the mixture, or a combination thereof.

15. The method according to claim 12 , wherein the antimicrobial and/or anti-odor, textile coating composition is applied to the textile from 2 weight % to 10 weight % on weight of fabric.

16. The method according to claim 12 , wherein the benzoic acid is present on the treated textile from 1.3 weight % to 9 weight % on weight of fabric.

17. The method according to claim 12 , wherein the benzoic acid is present on the treated textile from 1.5 weight % to 8.5 weight % on weight of fabric.

18. The method according to claim 12 , wherein the terephthalic acid is present on the treated textile from 0.2 weight % to 3.5 weight % on weight of fabric.

19. The method according to claim 12 , wherein the terephthalic acid is present on the treated textile from 0.3 weight % to 2.0 weight % based on weight of fabric.

20. The method according to claim 12 , wherein the method reduces bacterial growth on the treated textile material by a 3 log reduction or greater.

21. The method according to claim 12 , wherein the method reduces bacterial growth on the treated textile material by a 3 log reduction or greater after twenty-five home launderings.

22. The method according to claim 12 , wherein the textile material comprises polyester.
