The influence of sea water to UV absorber quenching of fluorescence

Textile and clothing provide some sun screening properties which highly depends on large number of factors, e.g. type of fibre, fabric surface and construction, wetness, type and concentration of dyestuff, fluorescent whitening agent (FWA), UV-B protective agents, as well as nanoparticles, if applied. Recently, the new stilbene type UV absorber was developed, for the application in textile finishing and care. Molecules of UV absorbers are able to absorb the damaging UV-R range of 290 nm to 360 nm, and convert it into harmless heat energy. As stilbene-type, this UV absorber show the phenomenon of fluorescence reemitting the energy at the blue region (typically 420-470 nm) of the spectrum, resulting in better whiteness and UV protection. Therefore, the whiteness and UV protective properties of cotton knitted and woven fabrics achieved by its application were researched in this paper, and the quenching phenomenon of UV absorber fluorescence was discussed.
