 Full text | Abstract: Several yellow and red bis-monochlorotriazine reactive dyes with built-in UV-absorber residues were synthesised. Their application properties were determined during the coloration of cotton, and the UV-protection factor (UPF) of the dyed fabrics was measured. The results of these measurements were compared with those obtained for coloration of the same fabrics carried out with the use of dyebaths containing a composition of a model dye and colourless fibre-reactive UV absorber. |
