Abstract
An article of footwear (100), apparel (500, 600), and/or sporting equipment (300, 400), and methods of manufacturing thereof, having a hydrogel present on at least a portion of an externally-facing side of the article. The hydrogel is effective in reducing soil accumulation on the article, and/or for reducing soil adhesion to the article.
Claims20
An article of footwear having a component comprising:
- a first surface of the component configured to be externally-facing and ground contacting;
- and
- a second surface of the component opposing the first surface;
- wherein the component comprises a material defining at least a portion of the first surface, and the material compositionally comprises a hydrogel, wherein the material comprises a polymeric network including one or more chains of a polyurethane, one or more chains of a polyamide homopolymer, and combinations thereof, wherein the material is present in the form of a filament that is at least a portion of a non-woven textile;
- or in the form of a yarn that is at least a portion of a woven textile, a knit textile, or a braided textile;
- or in the form of a film.

An article of footwear having a component comprising:
- a first surface of the component configured to be on the bottom of the article of footwear, ground contacting, and externally-facing;
- and
- a second surface of the component opposing the first surface;
- wherein the component comprises a material defining at least a portion of the first surface, and the material compositionally comprises a hydrogel, wherein the hydrogel of the material comprises a crosslinked polymer network, wherein the hydrogel of the material compositionally comprises semi-crystalline regions and amorphous regions, wherein the material is present in the form of a filament that is at least a portion of a non-woven textile;
- or in the form of a yarn that is at least a portion of a woven textile, a knit textile, or a braided textile;
- or in the form of a film.
