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) as at least one coated fiber, the cured coating including a plurality of pigment particles entrapped in a matrix of crosslinked polyurethane homopolymers or copolymers or both, wherein the cured coating is an elastomeric cured coating, and wherein the at least one coated fiber is visible on or through an externally-facing surface of the article of footwear.

2 . The component of claim 1 , wherein the matrix of crosslinked polymers includes crosslinked polyester polyurethanes, wherein the one or more coated fiber(s) include thermoplastic polyurethane fibers, thermoplastic polyamide fibers, thermoplastic polyester fibers, thermoplastic polyether fibers, thermoplastic polyolefin fibers, and any combination thereof.

3 . The component of claim 1 , wherein the at least one coated fiber includes glass fiber, carbon fiber, boron fiber and any combination thereof.

4 . The component of claim 1 , wherein the at least one coated fiber is present in a yarn, and the coating is disposed on an outer surface of the yarn; or wherein the one or more coated fiber(s) are present in a textile, and the coating is disposed on the externally-facing surface of the textile.

5 . The component of claim 1 , wherein the at least one coated fiber is attached to a composite component and consolidated with a substantially transparent resin material, wherein the substantially transparent resin material is a substantially transparent thermoplastic polyurethane resin material or a substantially transparent cured epoxy resin material.

6 . The component of claim 1 , wherein the pigment particles are selected from the group consisting of: metal and metal oxide pigments, carbon pigments, clay earth pigments, ultramarine pigments and a combination thereof.

7 . The component of claim 1 , wherein the component is a plate.

8 . The component of claim 1 , wherein the component is a textile.

9 . The component of claim 1 , wherein the matrix of crosslinked polymers includes crosslinked polyester polyurethanes, wherein the one or more coated fiber(s) include thermoplastic polyurethane fibers, thermoplastic polyamide fibers, thermoplastic polyester fibers, thermoplastic polyether fibers, thermoplastic polyolefin fibers, and any combination thereof.

10 . An article of footwear comprising:
an externally-facing surface; one or more fiber(s); and a cured coating disposed on the one or more fiber(s) as at least one coated fiber, the cured coating including a plurality of pigment particles entrapped in a matrix of crosslinked polyurethane homopolymers or copolymers or both, wherein the cured coating is an elastomeric cured coating, wherein the at least one coated fiber is visible on or through the externally-facing surface of the article of footwear.

11 . The article of claim 10 , wherein the at least one coated fiber includes thermoplastic polyurethane fibers, thermoplastic polyamide fibers, thermoplastic polyester fibers, thermoplastic polyether fibers, thermoplastic polyolefin fibers, and any combination thereof or wherein the one or more coated fiber(s) include glass fibers, carbon fibers, boron fibers and any combination thereof.

12 . The article of claim 10 , wherein the at least one coated fiber is present in a yarn, and the coating is disposed on an outer surface of the yarn.

13 . The article of claim 10 , wherein the at least one coated fiber is present in the form of a tow.

14 . The article of claim 10 , wherein the at least one coated fiber is present in a textile portion of the article of footwear.

15 . 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) as at least one coated fiber, the cured coating including a plurality of pigment particles entrapped in a matrix of crosslinked polyurethane homopolymers or copolymers or both, wherein the cured coating is an elastomeric cured coating, and the one or more coated fiber(s) are consolidated with a substantially transparent or translucent resin material, wherein the at least one coated fiber is visible on or through an externally-facing surface of the article of footwear.

16 . The component of claim 15 , wherein the at least one coated fiber includes thermoplastic polyurethane fibers, thermoplastic polyamide fibers, thermoplastic polyester fibers, thermoplastic polyether fibers, thermoplastic polyolefin fibers, and any combination thereof.

17 . The component of claim 15 , wherein the at least one coated fiber includes glass fibers, carbon fibers, boron fibers and any combination thereof.

18 . The component of claim 15 , wherein the at least one coated fiber is present in a yarn, and the coating is disposed on an outer surface of the yarn.

19 . The component of claim 15 , wherein substantially transparent resin material is selection from: a substantially transparent cured epoxy resin material or a substantially transparent thermoplastic polyurethane resin material.

20 . The component of claim 15 , wherein the at least one coated fiber is present in a textile or a plate.
