Multilayered materials with color changing properties
Described are articles of wear including with a material with color changing properties. The material includes at least one elastic portion having an unstretched colored appearance and a stretched colored appearance. The material also includes at least one fixed portion having the stretched colored appearance regardless of a magnitude of an external force applied to the at least one fixed portion.
1. A component of an article of wear, the component comprising:
a material with color changing properties comprising:
a first layer;
a third layer positioned below the first layer; and
a second layer positioned between the first layer and the third layer, wherein the second layer comprises a substantially translucent appearance in an unstretched condition, and a substantially opaque appearance in a stretched condition;
at least one elastic portion of the material comprising an unstretched colored appearance when the second layer is in the unstretched condition and a stretched colored appearance when the second layer is in the stretched condition, wherein the unstretched colored appearance is different from the stretched colored appearance; and
at least one fixed portion of the material comprising a permanently stretched condition, wherein the at least one fixed portion comprises the stretched colored appearance regardless of a magnitude of an external force applied to the at least one fixed portion, wherein:
the first, second, and third layers extend across an entire surface of the component such that the first layer is an outermost layer of the component; and
a change from the unstretched colored appearance to the stretched colored appearance occurs locally at a location of stretching of the at least one elastic portion.
2. The component of claim 1 , wherein the first layer comprises a first coloration, and the third layer comprises a second coloration that is different from the first coloration,
wherein the unstretched colored appearance comprises a combination of the first coloration and the second coloration, and
wherein the second coloration is concealed from the stretched colored appearance by the second layer.
3. The component of claim 2 , wherein the first coloration is complementary to the second coloration.
4. The component of claim 1 , wherein the second layer is polyurethane or thermoplastic polyurethane film.
5. The component of claim 1 , wherein a change from the unstretched colored appearance to the stretched colored appearance occurs based on an application of an external force in a plurality of nonparallel directions.
