Abstract

Included are compositions for fibers which include a clay nanoparticle and a wax. The composition provides the fibers with oil and water repellency.

First claim

The invention claimed is:

1. A composition in an aqueous dispersion comprising a combination of a soil repellent composition and a liquid repellent composition;
(a) said soil repellent composition comprising at least one clay nanoparticle component and optionally a first surfactant; and
(b) said liquid repellent composition comprising a wax and a second surfactant, wherein the wax comprises a mixture of paraffin wax, candellila wax, and a polyoxyalkylene.

2. The composition of claim 1 , wherein the composition excludes fluorochemicals.

3. The composition of claim 1 , wherein the composition is prepared in the absence of fluorochemicals.

4. The composition of claim 1 , wherein said at least one clay nanoparticle component comprises at least one member selected from the group consisting of smectites, kaolins, illites, chlorites, attapulgites, and combinations thereof.

5. The composition of claim 1 , wherein said at least one clay nanoparticle component comprises at least one member selected from the group consisting of montmorillonite, bentonite, pyrophyllite, hectorite, saponite, sauconite, nontronite, talc, beidellite, volkonskoite, vermiculite, kaolinite, dickite, antigorite, anauxite, indellite, chrysotile, bravaisite, muscovite, paragonite, biotite, corrensite, penninite, donbassite, sudoite, sepiolite, palygorskyte, and combinations thereof.

6. The composition of claim 1 , wherein said at least one clay nanoparticle component is synthetic.

7. The composition of claim 1 , wherein said at least one clay nanoparticle component is synthetic hectorite.

8. The composition of claim 1 , wherein said soil repellent composition further comprises an oligomeric or polymeric fluorochemical.

9. The composition of claim 8 , wherein said oligomeric or polymeric fluorochemical is selected from the group consisting of fluorinated allophanates, fluorinated polyacrylates, fluorinated urethanes, fluorinated oxetanes, fluorinated carbodiimides, fluorinated guanidines, fluorochemicals incorporating C2 to C8 chemistries, and combinations thereof.

10. The composition of claim 1 , wherein said at least one clay nanoparticle component is present in an amount from about 0.01% to about 25% weight of the composition.

11. The composition of claim 1 , wherein the first surfactant and second surfactants are the same.

12. The composition of claim 1 , wherein the first surfactant and second surfactant are independently selected from two or more different surfactants, wherein the surfactants are not a mixture of a cationic surfactant and an anionic surfactant.

13. The composition of claim 1 , wherein the first surfactant and second surfactant are independently selected from two or more different anionic surfactants.

14. The composition of claim 1 , wherein the composition further comprises a preservative or antimicrobial agent.

15. The composition of claim 1 , wherein the clay nanoparticle comprises about 4% to about 38% by weight of the soil repellent composition.

16. The composition of claim 1 , wherein the wax is about 5% to about 40% by weight of the liquid repellent composition.

17. The composition of claim 1 , wherein the second surfactant comprises a salt of oleic acid.

18. An article comprising fiber and a composition in an aqueous dispersion comprising a combination of a soil repellent composition and a liquid repellent composition;
(a) said soil repellent composition comprising at least one clay nanoparticle component and optionally a first surfactant; and
(b) said liquid repellent composition comprising a wax and a second surfactant wherein the wax comprises a mixture of paraffin wax, candelilla wax, and a polyoxyalkylene.

19. The article of claim 18 , wherein said article is a textile selected from the group consisting of a rug, carpet, yarn, bedding, clothing, window treatments, upholstery, and table coverings.

20. A method for providing soil and liquid repellency to an article comprising applying a composition to the article wherein said composition in an aqueous dispersion comprises a combination of a soil repellent composition and a liquid repellent composition;
(a) said soil repellent composition comprising at least one clay nanoparticle component and optionally a first surfactant; and
(b) said liquid repellent composition comprising a wax and a second surfactant wherein the wax comprises a mixture of paraffin wax, candelilla wax, and a polyoxyalkylene.

21. The method of claim 20 , wherein said composition is applied to the surface of the article.
