Lignin as a natural dye: We present the production of composite fibers that contain cellulose and lignin from an ionic liquid solution by dry-jet wet spinning. Two potential applications are pursued. The first approach aims to produce naturally dyed textile fibers. The second approach is to utilize the composite fiber as a precursor for carbon fibre production.
