Active and adaptive photochromic fibers, textiles and membranes
First Claim
1. A process to make a dyed fiber which comprises mixing at least one dye capable of changing color and said dye comprises photochromic compound, magnetochromic compound, electrochromic compound, thermochromic compound, piezochromic compound, or leuco body and at least one polymer into at least one solvent at a temperature below the temperature at which the dye or polymer degrades to form a polymer dye solution and electrospinning said polymer dye solution to form a fiber wherein the dye penetrates more than the surface of the fiber.

Abstract
A process to make a dyed fiber which has the steps of mixing a dye capable of changing color and a polymer into a solution at a temperature below the temperature at which the dye or polymer degrades to form a polymer dye solution and electrospinning said polymer dye solution to form a fiber wherein the dye penetrates more than the surface of the fiber. The invention also relates to the fiber and use of the fiber.
