Sažetak
Beside the vital and powerful role of sun in our everyday lives the overdose of UV radiation on skin can lead to potential skin damage from exposure to the sun's ray. Compare with visible light that interacts with dyes UV radiation interacts with ultraviolet absorbers and fluorescent whitening agents. Middle UV-rays (UV-B region, l=280-315 nm) causes acute and chronic reactions and damages such as skin reddening or increased risk for other diseases. For such reason it is important to protect the people from the ultraviolet radiation falling on garments and sun-screening textiles such as tends. The level of such protection of fabric depends of a large number of factors as the type of fiber, porosity, density, moisture, color and FWA in the case of white textiles. In this paper cationized cotton fabric was treated with UV reactive apsorber on the base of oxalanilide, Tinofast CEL, to improve the UPF of fabric. Exacust method was applied following peroxide bleaching and optical bleaching procedure. For optical bleaching three stilben derivates as optical brighteness agents were used in wide concentration range. The UV protection factor (UPF) measurements were done using Varian Carry-50 AnAs UV-Vis spectrophotometer, the whiteness degree and yellowness by Datacolor Spectraflash 600 plus-CT and relative intensity of fluorescence by Carl-Zeiss Fluorometer. The aim of the paper was to study the FWA's fluorescence changes of sunprotected white cotton fabric.
