Products made of fluorescent textiles have a variety applications, most notably as smart for human safety during outdoor sports, well detecting authenticity and avoiding counterfeiting. Fluorescence in fabrics is obtained via dyeing or printing the by inks which based on organic dyes, rare earth metal, dendrimers. This review highlights discuss fundamental ideas fluorescence, coloring materials (organic inorganic), processes used to prepare some ink formulations, other related topics. Additionally, we discussed their capacity print various surfaces using methods reviewing current advancements clear way further studies this area.

Smart photochromic and fluorescent textile refers to garments that alter their colorimetric properties in response external light stimulus. Cotton fibers have been reported as a main resource for many non-textile industries, such automobiles, medical devices, furniture applications. is natural fiber distinguished with breathability, softness, cheapness, highly absorbent. However, there growing demands find other resources cotton textiles at high quality low cost various applications, sensor harmful ultraviolet radiation. Herein, we present novel method toward luminescent nonwoven from recycled waste. Using the screen-printing technology, fabric both was developed using aqueous inorganic phosphor nanoparticles (10-18 nm)-containing printing paste. Both CIE Lab color coordinates photoluminescence spectra showed transparent film printed on develops reversible green emission (519 nm) under (365 nm), even pigment concentration (2%) Colorfastness of fabrics durability photostability.
