cze	Reaktivní UV absorber na bázi fenylbenzimidazolu a jeho aplikace na celulózové materiály	Byly připraveny nové typy UV absorberů na bázi fenylbenzimidazolu. Jedná se o reaktivní typy, které byly aplikovány na bavlněné tkaniny. Dochází k výraznému zvýšení ochranného faktoru vůči UV záření takto upravených tkanin. Nové typy UV adsorberů je na bavlněné tkaniny možno aplikovat společně s opticky zjasňujícími prostředky a barvivy.	UV absorbery;fenylbenzimidazol;celulosové materiály
eng	Reactive phenylbenzimidazole UV absorbers and their application to cellulose textiles	New types of reactive UV absorbers for applications to cellulose textiles have been prepd. These substances are condensation products of sulfobenzimidazolaniline, cyanuric chloride, and aminophenyl-(2-sulfethoxy)-sulfone. They were applied to bleached, unbleached, as well as dyed cellulose textiles with the aim to increase the protection effect of these textiles against UV radiation. All the tested textiles showed a marked increase in the UV protection factor (UPF). The effects of the UV absorbers tested neither interfere with the function of fluorescent brighteners (FBs) nor affect the hue of the used dyestuffs. They exhibit synergistic effect in the protection effectiveness against UV radiation: the UV absorbers used together with dyestuffs and FBs have a higher UPF factor than is the sum of UPF contributions of the individual components	UV absorbers;phynylbezimidazole;cellulose textiles
