Abstract

One or more aspects of the present disclosure are directed to aqueous solutions that can be used to make substrates such as an article that can inhibit or limit one or more sources of odor. In an aspect, the aqueous solution can include one or more components, where one of the components is an inhibiting agent that can function to inhibit or limit the sources of odor in an article such as a textile.

First claim

I claim:

1. A method of treating a substrate, comprising:
exposing the substrate to an aqueous solution comprising trehalose and one or more of the following: polyacrylic acid, sodium hypophosphite, and polyethylene glycol ester;
drying the substrate; and
curing the substrate to form a treated substrate.

2. The method of claim 1 , wherein the concentration of the trehalose is about 0.01 to less than 5 wt % of the solution.

3. The method of claim 1 , wherein the concentration of the trehalose is about 0.01 to about 4 wt % of the solution.

4. The method of claim 1 , wherein the concentration of the trehalose is about 0.01 to 1 wt % of the solution.

5. The method of claim 1 , wherein the surface coating comprises two or more of the following: polyacrylic acid, sodium hypophosphite, and polyethylene glycol ester.

6. The method of claim 1 , wherein the surface coating comprises each of the following: polyacrylic acid, sodium hypophosphite, and polyethylene glycol ester.

7. The method of claim 1 , wherein the aqueous solution comprises:
a trehalose at about 0.01 to 10 weight % of the solution and one or more of the following:
polyacrylic acid at about 0.01 to 5 weight % of the solution;
sodium hypophosphite at about 0.01 to 10 weight % of the solution; and
polyethylene glycol ester at about 0.01 to 6 weight % of the solution.

8. The method of claim 7 , wherein the concentration of the trehalose is about 0.01 to less than 5 wt % of the solution.

9. The method of claim 7 , wherein the concentration of the trehalose is about 0.01 to about 4 wt % of the solution.

10. The method of claim 7 , wherein the concentration of the trehalose is about 0.01 to 1 wt % of the solution.

11. The method of claim 1 , wherein two or more of the following are included in the aqueous solution:
a carboxymethyl cellulose salt at about 0.01 to 5 weight % of the solution;
polyacrylic acid at about 0.01 to 5 weight % of the solution;
sodium hypophosphite at about 0.01 to 10 weight % of the solution; and
polyethylene glycol ester at about 0.01 to 6 weight % of the solution.

12. The method of claim 1 , wherein three or more of the following are included in the aqueous solution:
a carboxymethyl cellulose salt at about 0.01 to 5 weight % of the solution;
polyacrylic acid at about 0.01 to 5 weight % of the solution;
sodium hypophosphite at about 0.01 to 10 weight % of the solution; and
polyethylene glycol ester at about 0.01 to 6 weight % of the solution.

13. The method of claim 1 , wherein the aqueous solution includes each of:
a carboxymethyl cellulose salt at about 0.01 to 5 weight % of the solution;
polyacrylic acid at about 0.01 to 5 weight % of the solution;
sodium hypophosphite at about 0.01 to 10 weight % of the solution; and
polyethylene glycol ester at about 0.01 to 6 weight % of the solution.

14. The method of claim 1 , wherein the substrate comprises a textile.

15. The method of claim 1 , wherein the textile is an article of apparel or a component of apparel.

16. The method of claim 1 , wherein the textile is an article of footwear or a component of footwear.

17. The method of claim 1 , wherein the textile comprises a polyester-polyurethane copolymer.

18. An article, comprising: a treated substrate made from the method of claim 1 .

19. The article of claim 18 , wherein the textile is an article of apparel or a component of apparel or an article of footwear or a component of footwear.

20. The article of claim 19 , wherein the aqueous solution includes each of:
a carboxymethyl cellulose salt at about 0.01 to 5 weight % of the solution;
polyacrylic acid at about 0.01 to 5 weight % of the solution;
sodium hypophosphite at about 0.01 to 10 weight % of the solution; and
polyethylene glycol ester at about 0.01 to 6 weight % of the solution.
