This chapter describes the applications of nanotechnology in textile coloration highlighting resourceful, cost-effective methods among other innovative aspects of textiles industries. Using nanoparticles like gold and silver, colors are brightened by surface plasmon resonance as well as being less toxic than traditional methods with reduced discharge of hazardous wastewater. Nanoparticles can be used to improve dyeing quality, structural colorations, and UV protection supplemental effects. Gold nanoparticles have the potential for imparting a variety of colors to textile materials. Using silver nanoparticles endows enhanced characteristics, such as antibacterial, and hydrophobic properties. Different studies include applications of various nanoparticles on silk, cotton, and wool textiles showing increased color fastness that does not affect the handle of the fabric. Methods like in-situ synthesis increase the binding of nanoparticles which improves wash fastness. In this chapter, the implementations of nanotechnology has been showcased as innovative and sustainable textile dyeing processes providing the benefits of enhanced color quality, feature depth, and pigment adherence for superior visual effects.
