Abstract
Official abstract text for this publication.
A method of forming a color-changing fiber that can be incorporated into fabrics and other woven materials. The color changing fibers include an annular wall and a conductive wire axially extending through the annular wall, a core strand surrounded by the annular wall and extending axially through a central portion of the fiber, and an encapsulated electro-optic medium disposed on a surface of the core strand.
First claim
Opening claim text (preview).
The invention claimed is: 1. A method of making a flexible color-changing fiber comprising: coating at least a portion of a surface of a conductive core strand with capsules including an electrophoretic medium to create a coated core strand; drying the capsules including an electrophoretic medium onto the surface of the conductive core strand to create a dried coated core strand; inserting the dried coated core strand through a preform comprising a conductive wire; and drawing down the preform to form a fiber comprising an annular wall, such that the conductive wire extends axially through the annular wall and the dried coated core strand extends axially through a central portion of the fiber. 2. The method of claim 1 , wherein the electrophoretic medium comprises a non-polar solvent and two types of charged pigment particles, each type of charged pigment particles having a charge polarity and color different from the other.
