Název v původním jazyce

Application of benzotriazole reactive UV absorbers to cellulose and determining sun protection of treated fabric spectrophotometrically

Popis výsledku v původním jazyce

UV absorbers for treating cotton textiles with the aim of increased protection against harmful effects of UV component of solar radiation have been prepared by reactions of five different aminophenylsulfobenzotriazoles with the condensation product of 4-aminophenyl-sulfatoethylsulfone and cyanuric chloride. The UV absorbers with two different reactive groups (monochloro-triazine and aromatic vinylsulfone), capable of formation of covalent bonds with hydroxyl groups of cellulose, were applied to one cellophane foil and two cotton fabrics of different porosities. This treatment increased the ultraviolet protection factor from a value of UPF = 3 to UPF 100 and above. For attaining a high UPF value, the cotton material should exhibit low porosity. The UV absorbers with 2-hydroxyphenyl group are stable in light and do not fluoresce on the fabric on contrary to derivatives without 2-hydroxyphenyl group or with 2-methoxyphenyl group. The high photostability of absorbers is explained by the po
