Abstract
Disclosed herein is a textile dyeing process. The method comprises surface functionalization of a fiber using a poly-ionic polymer followed by contacting the fiber with an aqueous color solution comprising a protein bonded light harvesting chromophore. The color is then deposited and fixed on to the surface of the fiber followed by cross-linking with a bi-functional protein cross-linking agent.
