Abstract: A color-changing product includes a fabric and a connection bus disposed along at least a portion of the fabric. The fabric includes a plurality of color-changing fibers. Each of the plurality of color-changing fibers has an electrically conductive core and a coating disposed around and along the electrically conductive core. The coating includes a color-changing pigment. The connection bus has a multi-layer structure including a metallic foil layer and a film layer. The metallic foil layer forms a weld between at least a subset of the plurality of color-changing fibers so that current can flow through the connection bus and into the electrically conductive core of at least the subset of the plurality of color-changing fibers. The film layer at least partially isolates the weld from a surrounding environment.

Abstract: A method of manufacturing a color-changing fiber includes loading a polymeric material and a thermochromic pigment material into a fiber fabrication machine that comprises an extruder and a spinneret, operating the extruder to provide a molten mixture of the polymeric material and the thermochromic pigment material, providing a volume of the molten mixture to the spinneret, and operating the spinneret to coat an electrically conductive core with the molten mixture to form a coating layer around the electrically conductive core to produce the color-changing fiber. The polymeric material and the thermochromic pigment material are provided as (a) a first raw material comprising the polymeric material and a second raw material comprising the thermochromic pigment material or (b) a thermochromic pigment and polymer mixture.

Abstract: A color-changing product includes a fabric. The fabric includes a first layer and a second layer. The first layer is arranged using at least one fiber. The at least one fiber includes (a) an electrically conductive core and (b) a coating disposed around and along the electrically conductive core. The second layer is printed onto the first layer. The second layer includes a foreground thermochromic pigment that is selectively activatable by providing an electrical current to the electrically conductive core of the at least one fiber to change at least one of a foreground color or a pattern of the second layer.
