Abstract

The present disclosure is directed to articles that include one or more coated fiber(s) (i.e., fiber(s) with a cured coating disposed thereon), where the coating includes a matrix of crosslinked polymers and optionally a colorant (e.g., pigment particles or dye or both). The cured coating is a product of crosslinking a coating composition including uncrosslinked polymers (e.g., a dispersion of uncrosslinked polymers in a carrier, wherein the uncrosslinked polymers are crosslinked to form the matrix of crosslinked polymers). The present disclosure is also directed to articles including the coated fibers, methods of forming the coated fibers and articles, and methods of making articles including the coated fibers.

First claim

What is claimed is:

1. A component of an article of footwear comprising:
one or more fiber(s); and
a cured coating disposed on the one or more fiber(s), the cured coating including a plurality of pigment particles entrapped in a matrix of crosslinked polyurethane homopolymers or copolymers or both, wherein the article is a composite component, and the one or more coated fiber(s) are attached to a substrate and consolidated with a substantially transparent resin material, wherein the substantially transparent resin material is a substantially transparent cured epoxy resin material.

2. The component of claim 1 , wherein the cured coating is an elastomeric cured coating.

3. The component of claim 1 , wherein the matrix of crosslinked polymers includes crosslinked polyester polyurethanes.

4. The component of claim 1 , wherein the one or more coated fiber(s) include thermoplastic polyurethane fibers, thermoplastic polyimide fibers, thermoplastic polyester fibers, thermoplastic polyether fibers, thermoplastic polyolefin fibers, and any combination thereof.

5. The component of claim 1 , wherein the one or more coated fiber(s) include glass fibers, carbon fibers, boron fibers and any combination thereof.

6. The component of claim 1 , wherein the one or more coated fiber(s) are present in a yarn, and the coating is disposed on an outer surface of the yarn.

7. The component of claim 6 , wherein the component is a component of an upper for an article of footwear.

8. The component of claim 1 , wherein the one or more coated fiber(s) are present in a textile, and the coating is disposed on an outer surface of the textile.

9. The component of claim 1 , wherein the composite component is a plate for an article of footwear, and the at least one coated fiber is visible on or through a side of the plate configured to be ground-facing during use.

10. A method of making a component of an article of footwear, the method comprising:
disposing a coating composition onto one or more fiber(s), wherein the coating composition comprises a dispersion of uncrosslinked polyurethanes and pigment particles in a carrier;
curing the coating composition on the one or more fiber(s), crosslinking polyurethanes to form a matrix of crosslinked polyurethanes, and forming a cured coating including a plurality of the pigment particles entrapped in the matrix of crosslinked polyurethanes; and
affixing the one or more fiber(s) to a substrate prior to the disposing the coating composition onto the one or more fiber(s).

11. The method of claim 10 , wherein the carrier is water or an aqueous solution.

12. The method of claim 10 , wherein the coating composition comprises a thermally-initiated crosslinking agent.

13. The method of claim 10 , wherein the disposing comprises spraying the coating composition onto the one or more fiber(s).

14. The method of claim 10 , wherein the affixing comprises stitching or embroidering a tow of fibers including the coated fiber(s) to the substrate.

15. The method of claim 10 , wherein the method further comprises:
disposing a liquid resin material onto the one or more coated fiber(s), wetting the one or more coated fiber(s) with a liquid resin material; and
solidifying the liquid resin material surrounding and consolidating the one or more coated fiber(s) with solid resin material, forming a composite component.

16. The method of claim 15 , wherein the liquid resin material comprises a liquid uncured epoxy resin material, and the solidifying the resin material comprises curing the liquid uncured epoxy resin material and forming a substantially transparent solid, cured epoxy resin material.

17. A method of making a component of an article of footwear, the method comprising:
disposing a coating composition onto one or more fiber(s), wherein the coating composition comprises a dispersion of uncrosslinked polyurethanes and pigment particles in a carrier;
curing the coating composition on the one or more fiber(s), crosslinking the polyurethanes to form a matrix of crosslinked polyurethanes, and forming a cured coating including a plurality of the pigment particles entrapped in the matrix of crosslinked polyurethanes,
disposing a liquid resin material onto the one or more coated fiber(s), wetting the one or more coated fiber(s) with a liquid resin material; and
solidifying the liquid resin material surrounding and consolidating the one or more coated fiber(s) with solid resin material, forming a composite component,
wherein the liquid resin material comprises a liquid uncured epoxy resin material, and the solidifying the resin material comprises curing the liquid uncured epoxy resin material and forming a substantially transparent solid, cured epoxy resin material.
