ANTIMICROBIAL POLYMER COATINGS ON TEXTILES
A composition having sodium pyrithione and a binder is provided. The composition may also have a softener. A method of using the composition is provided. The method includes applying a composition to a textile. A method of treating the textile with the composition to impart an antimicrobial and/or antifungal efficacy and durability is also provided.
1 . An antimicrobial composition comprising:
from 6 weight % to 16 weight % of sodium pyrithione,
from 10 weight % to 25 weight % of binder, and
a balance of water,
wherein the weight percentages are based on a total weight of the composition.
2 . The antimicrobial composition according to claim 1 , further comprising from 10 weight percent to 30 weight percent of a softener.
3 . The antimicrobial composition according to claim 1 , wherein the composition is heavy metal-free.
4 . The antimicrobial composition according to claim 1 , wherein the binder is selected from the group consisting of a polyacrylic binder, a polyurethane binder, and a combination thereof.
5 . The antimicrobial composition according to claim 2 , wherein the softener is selected from the group consisting of a sulphated fatty alcohol, anionic fatty acid polysiloxane, nonionic fatty acid polysiloxane, ethoxylated polysiloxane, polyethylene based softener, and a combination thereof.
6 . A method of treating a textile, the method comprising:
applying a composition to a textile, wherein the composition comprises 6 weight % to 16 weight % of sodium pyrithione, 10 weight % to 25 weight % of binder, and a balance of water,
thereby imparting antimicrobial efficacy to the textile.
7 . The method of claim 6 , wherein the composition is heavy metal-free.
8 . The method according to claim 6 , wherein the composition further comprises from 10 weight % to 30 weight % of a softener.
9 . The method according to claim 6 , wherein the textile is a fabric.
10 . The method according to claim 6 , wherein the binder is selected from the group consisting of a polyacrylic binder, a polyurethane binder, and a combination thereof.
11 . The method according to claim 8 , wherein the softener is selected from the group consisting of a sulphated fatty alcohol, anionic fatty acid polysiloxane, nonionic fatty acid polysiloxane, ethoxylated polysiloxane, polyethylene based softener, and a combination thereof.
12 . The method according to claim 6 , wherein the composition is applied by a method selected from the group consisting of padding, spraying, roller coating, exhaustion, and a combination thereof.
13 . The method according to claim 12 , wherein the composition is applied to the textile by padding in a padding bath.
14 . The method according to claim 13 , wherein the textile after padding is cured at a curing temperature in a range of 130° C. to 180° C.
15 . The method according to claim 13 , wherein the textile after padding is cured for a minimum of 45 seconds.
16 . The method according to claim 12 , wherein the composition is added during a dyeing stage of exhaustion.
17 . The method according to claim 12 , wherein the composition is added at a temperature in a range of 60° C. to 130° C.
18 . The method according to claim 12 , wherein the composition is exhausted for twenty minutes to one hour.
19 . An article, the article comprising a textile material, wherein the textile material is treated with a composition comprising:
sodium pyrithione at an effective amount to reduce fungal growth on the textile, and
a binder at an effective amount to coat the textile.
20 . The article according to claim 19 , wherein the sodium pyrithione is present from 6 weight % to 16 weight %.
21 . The article according to claim 19 , wherein the binder is present from 10 weight % to 25 weight %.
22 . The article according to claim 19 , wherein the composition is heavy metal-free.
23 . The article according to claim 19 , wherein the binder is selected from the group consisting of polyacrylic binder, a polyurethane binder, and a combination thereof.
24 . The article according to claim 19 , wherein the composition further comprises from 10 weight percent to 30 weight percent of a softener.
25 . The article according to claim 19 , wherein water is the balance of the total weight of the composition.
