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. An article of apparel with anti-odor properties, comprising:
a plurality of polyester fibers or yarns comprising a durable surface coating, wherein the durable surface coating comprises an aldehyde inhibitor configured to inhibit generation of volatile aldehydes on a treated article of apparel, and a cross-linker,
wherein the aldehyde inhibitor comprises a polysaccharide that is covalently bonded to the plurality of polyester fibers or yarns through the cross-linker.

2. The article of apparel of claim 1 , wherein the cross-linker is selected from the group consisting of: a polycarboxylic acid crosslinking agent, an aldehyde crosslinking agent, a polyisocyanate crosslinking agent, and a combination thereof.

3. The article of apparel of claim 1 , wherein the plurality of polyester fibers or yarns comprise polyethylene terephthalate fibers or yarns.

4. The article of apparel of claim 1 , wherein the durable surface coating comprises one or more of the following: polyacrylic acid, sodium hypophosphite, and polyethylene glycol ester.

5. The article of apparel of claim 1 , wherein, after exposing the treated article of apparel to 25 wear, wash and dry cycles, the durable surface coating remains effective in inhibiting generation of volatile aldehydes on the treated article of apparel.

6. The article of apparel of claim 1 , wherein the durable surface coating is the product of exposing an untreated article of apparel to an aqueous solution comprising the aldehyde inhibitor and the cross-linker, drying the exposed article of apparel, and curing the exposed article of apparel to activate the cross-linker and cross-link the durable surface coating, forming the treated article of apparel.

7. The article of apparel of claim 1 , wherein the aldehyde inhibitor comprises trehalose.

8. The article of apparel of claim 1 , wherein the durable surface coating further comprises one or more of a stain release agent, a softener, and an alkali metal salt catalyst.

9. The article of apparel of claim 8 , wherein the stain release agent is selected from the group consisting of: carboxymethyl cellulose salt, an oligomeric copolymer of terephthalic acid with ethylene glycol and polyethylene glycol, carboxy based hydrophilic polymer, and a combination thereof.

10. The article of apparel of claim 8 , wherein the softener is selected from the group consisting of: polyethylene glycol ester, polyethylene terephthalate copolymer, derivatives of polyethylene terephthalate, and a combination thereof.

11. The article of apparel of claim 8 , wherein the alkali metal salt catalyst is selected from the group consisting of: alkali metal hypophosphites, alkali metal phosphites, alkali metal polyphosphonates, alkali metal phosphates, and alkali metal sulfonates.

12. The article of apparel of claim 1 , wherein the durable surface coating is configured to cure at a temperature of about 120° C. to about 160° C.

13. An article of apparel with anti-odor properties, comprising:
a plurality of polyester fibers or yarns, comprising polyethylene terephthalate fibers or yarns, wherein the plurality of polyester fibers or yarns comprises a durable surface coating, wherein the durable surface coating is uniformly distributed throughout an article of apparel thickness, the durable surface coating comprising a cross-linker and an aldehyde inhibitor, wherein the aldehyde inhibitor comprises a polymeric composition, wherein the durable surface coating is configured to inhibit generation of volatile aldehydes on the article of apparel during or following wear, and wherein the aldehyde inhibitor is covalently bonded to the at least one of the polyethylene terephthalate fibers or yarns through the cross-linker.

14. The article of apparel of claim 13 , wherein the durable surface coating further comprises one or more of the following: a stain release agent, a softener, and an alkali metal salt catalyst.

15. The article of apparel of claim 13 , wherein the cross-linker is selected from the group consisting of: a polycarboxylic acid crosslinking agent, an aldehyde crosslinking agent, a polyisocyanate crosslinking agent, and a combination thereof.

16. The article of apparel of claim 13 , wherein the durable surface coating is configured to cure at a temperature of about 120° C. to about 160° C.

17. An article of apparel with anti-odor properties, comprising:
a plurality of polyester fibers or yarns comprising
a durable surface coating configured to remain in the article of apparel for at least 25 wear, wash and dry cycles, and wherein the durable surface coating comprises an aldehyde inhibitor configured to inhibit generation of volatile aldehydes on a treated article of apparel, and a cross-linker, wherein the aldehyde inhibitor is covalently bonded to the plurality of polyester fibers or yarns through the cross-linker.

18. The article of apparel of claim 17 , wherein the cross-linker is selected from the group consisting of: a polycarboxylic acid crosslinking agent, an aldehyde crosslinking agent, a polyisocyanate crosslinking agent, and a combination thereof.

19. The article of apparel of claim 17 , wherein the aldehyde inhibitor is bonded to the plurality of polyester fibers or yarns.

20. The article of apparel of claim 17 , wherein the durable surface coating further comprises one or more of a stain release agent, a softener, and an alkali metal salt catalyst.

21. The article of apparel of claim 1 , wherein the aldehyde inhibitor has an odor reduction rate of at least 7.2 percent after 25 wash cycles.
