Fluorescence in Smart Textiles

Abstract

Fluorescence has been identified as an advantageous feature in smart fabrics, notably for the protection of humans during outdoor athletic activities, as well as for preventing counterfeiting and determining authenticity. Fluorescence in smart fabrics is achieved using dendrimers, rare earth metal compounds, and fluorescent dye. The principal method for producing fluorescent fabrics is to immerse the sample in a solution containing fluorescent agents. However, covalent connections between fluorophores and textile substates should be established to improve the stability and intensity of the fluorescent characteristics. Fabric can be fluorescent throughout, or fluorescent fibers can be woven directly into the textile structures, made of natural (cotton, silk) or synthetic (polyamide- and polyester-based) fibers, into a precise pathway that becomes visible under ultraviolet irradiation.

Smart E-textiles: A review of their aspects and applications

“…Fluorescent fabrics and innovation (e.g., fabric-based electronic image displays, security barcodes, sensors) add value for human safety in outdoor sports and special services in the armed forces, fashion, and trends. 68 Some researchers use nanoparticles for blocking ultraviolet radiation as non-toxic in nature, very compatible with human skin, and chemically more stable at high temperatures and UV region. 69 Ultraviolet protection factor of woven or knitted fabrics has a higher coverage factor than other fabrics; knitted fabric structures are observed as the wavelength increases resulting in lower protection levels in the UVA region.…”
