Abstract

A fiber and method for making the same is disclosed that comprises a surface treatment, wherein the surface treatment comprises at least one clay nanoparticle component present in an amount greater than 2000 ppm on the surface of the fiber. Also disclosed is a fiber and method for making the same, comprising a surface treatment, wherein the surface treatment comprises at least one clay nanoparticle component and excludes flourochemicals.

First claim

1 . A fiber comprising a surface treatment, wherein the surface treatment comprises at least one clay nanoparticle component present in an amount greater than 2000 ppm on the surface of the fiber.

2 . The fiber of claim 1 wherein the at least one clay nanoparticle component is selected from the group consisting of: montmorillonite, bentonite, pyrophyllite, hectorite, saponite, sauconite, nontronite, talc, beidellite, volchonskoite, vermiculite, kaolinite, dickite, antigorite, anauxite, indellite, chrysotile, bravaisite, suscovite, paragonite, biotite, corrensite, penninite, donbassite, sudoite, pennine, sepiolite, polygorskyte, and combinations thereof.

3 . The fiber of claim 1 wherein the at least one clay nanoparticle component is synthetic.

4 . The fiber of claim 3 wherein the at least one clay nanoparticle component is synthetic hectorite.

5 . The fiber of claim 1 wherein the surface treatment further comprises a fluorochemical, wherein said fluorochemical is present in an amount that results in a surface fluorine content from about 0 ppm to about 50 ppm on the surface of the fiber.

6 . The fiber of claim 1 wherein the at least one clay nanoparticle is synthetic hectorite in an amount from about 2500 ppm to about 15,000 ppm on the surface of the fiber.

7 . The fiber of claim 1 wherein the at least one clay nanoparticle is synthetic hectorite in an amount from about 4000 ppm to about 10,000 ppm on the surface of the fiber.

8 . The fiber of claim 1 wherein the fiber is comprised of at least one polyamide resin selected from the group consisting of nylon 6,6, nylon 6, nylon 7, nylon 11, nylon 12, nylon 6,10, nylon 6,12, nylon 6,12, nylon DT, nylon 6T, nylon 6I and blends or copolymers thereof.

9 . The fiber of claim 1 wherein the fiber is comprised of at least one polyester resin selected from the group consisting of polyethylene terephthalate, polytrimethylene terephthalate, polybutylene terephthalate, polyethylene naphthalate and blends or copolymers thereof.

10 . The fiber of claim 1 wherein the at least one polyester resin is polyethylene terephthalate.

11 . The fiber of claim 1 wherein the at least one polyamide resin is nylon 6,6.

12 . The fiber of claim 1 further comprising a component selected from the group consisting of silicones, optical brighteners, antibacterial components, anti-oxidant stabilizers, coloring agents, light stabilizers, UV absorbers, basic dyes, and acid dye, and combinations thereof.

13 . A textile comprising a fiber from claim 1 .

14 . A carpet comprising a fiber from claim 1 .

15 . The carpet of claim 14 wherein the Delta E is about 85% or less than that of an untreated carpet when measured using ASTM D6540.

16 . The carpet of claim 14 wherein the Delta E is about 50% or less than that of an untreated carpet when measured using ASTM D6540.

17 . The carpet of claim 14 wherein the flame retardancy is improved by about 10% or better when compared to an untreated carpet, wherein the flame retardancy is measured by critical radiant flux using ASTM method E648.

18 . The carpet of claim 14 wherein the flame retardancy is improved by about 30% or better when compared to an untreated carpet, wherein the flame retardancy is measured by critical radiant flux using ASTM method E648.

19 . A method of making a fiber comprising:
a) applying a surface treatment on the fiber, wherein the surface treatment comprises at least one clay nanoparticle component present in an amount greater than 2000 ppm on the surface of the fiber; and b) heat curing the fiber.

20 . The method of claim 19 wherein the surface treatment is applied using a technique selected from the group consisting of spraying, dipping, exhaustive application, coating, foaming, painting, brushing, and rolling.

21 . The method of claim 19 wherein the surface treatment is applied by spraying.

22 . The method of claim 19 wherein said at least one clay nanoparticle component is selected from the group consisting of: montmorillonite, bentonite, pyrophyllite, hectorite, saponite, sauconite, nontronite, talc, beidellite, volchonskoite, vermiculite, kaolinite, dickite, antigorite, anauxite, indellite, chrysotile, bravaisite, suscovite, paragonite, biotite, corrensite, penninite, donbassite, sudoite, pennine, sepiolite, polygorskyte, and combinations thereof.

23 . The method of claim 16 wherein the surface treatment further comprises a flurochemical, wherein said fluorochemical is present in an amount that results in a surface fluorine content from about 0 ppm to about 50 ppm on the surface of the fiber.

24 . The method of claim 19 wherein said at least one clay nanoparticle is synthetic hectorite in an amount from about 2500 ppm to about 15,000 ppm on the surface of the fiber.

25 . The method of claim 19 wherein said at least one clay nanoparticle is synthetic hectorite in an amount from about 4000 ppm to about 10,000 ppm on the surface of the fiber.

26 . The method of claim 19 wherein the fiber is comprised of at least one polyamide resin selected from the group consisting of nylon 6,6, nylon 6, nylon 7, nylon 11, nylon 12, nylon 6,10, nylon 6,12, nylon 6,12, nylon DT, nylon 6T, nylon 6I and blends or copolymers thereof.
