Disperse Fluorescent Dyes

Fluorescent Dyes have long been used mainly for the dyeing of flat materials, especially textiles. The use of fluorescent dyes causes a significant increase in color brightness, which makes the dyed materials more easily perceptible, or more accurately visible. Indeed, fluorescent dyes are considered to be those dyes which absorb and emit radiation in the visible spectral range light and causes fluorescence. These dyes are defined as a group of organic dyestuffs which, when applied to a textile material, give rise to fluorescence under UV radiation and in daylight. In the textile field, the main use of fluorescent dyes is in the coloration of synthetic fibers, especially polyester, polyamide and acrylics in conjunction with elastane fibers, for fashion, leisure, sportswear uses and especially for safety. In industry, many textile materials are dyed with mixtures of dyes to achieve the exact reproducibility of the required color. The use of two or three fluorescent dyes with non-identical properties can affect the sorption of the dye and the high visibility.
