Nanotechnology has emerged as one of the most significant fields of study in recent years. Due to its special synthesis methods and advantageous properties, nanotechnology is quickly taking over the textile sector. Various finishing, coating, and manufacturing procedures are utilized to create fibers or fabrics with nano-sized particles in the production of high-performance textiles. Nanomaterials have been used to provide antibacterial, UV-resistant, electric conductivity, photocatalytic and self-cleaning qualities to fabrics and clothing in a sustainable way. nanofibers, silver, gold, and zinc nanoparticles, as well as stretchable textiles and wearable solar textiles, triboelectric nanogenerators, and one-piece self-power/self-charging power textiles have all been used in smart wearable textiles.
