A dyeing and welding process may be configured to convert a substrate into a welded substrate having at least some color imparted thereto via a dye and/or coloring agent by applying a process solvent having a dye and/or coloring agent therein to the substrate, wherein the process solvent interrupts one or more intermolecular force between one or more component in the substrate. The substrate may be configured as a natural fiber, such as cellulose, hemicelluloses, and silk. The process solvent may include a binder, such as dissolved biopolymer (e.g., cellulose). After application of a process solvent comprised of a dye and/or coloring agent, the substrate may be exposed to a second application of a process solvent comprised of a binder, which second application may occur before or after a process temperature/pressure zone, process solvent recovery zone, and/or drying zone.
