摘要

The publication presents investigation results and statistical analysis showing that by varying the chemical structure of optical brighteners from the derivative group of stilbene used for fabrics of artificial cellulose fibre modification, resulting in a different manufacturing process, it is possible to predict the level of the UPF value of the index of such modified fabric. In addition, statistically it was confirmed by results from early research that both the fibre finish (in this case, roughening the pigment 710 2) used for fabric manufacture as well as the FBA concentration used for fabric modification influence their UPF index value. Fabric UV-barrier studies also showed that despite a partial decrease in UPF values for such finished fabrics, the dependence of such an index on subtle dfferences in the chemical structure of the FBAs is maintained. Primarily the possibility and range of improving textile barriers against UV radiation through the use of the UV-absorption abilities of optical brighteners with subtle differences in their chemical structure was recognised, creating a premise to elaborate a mathematical control concept to steer a textile UV-barrier.
