Abstract
Three new azo reactive dyes of different metallic salts (Na, K, Li) were synthesized. The dyes were purified-concentrated by ultrafiltration technology, characterized and applied on cotton, wool and nylon 66 fabric by exhaustion (dyeing) and by ink-jet printing. Fastness properties of the dyeings were measured. Wash fastness was found to be very good to excellent in all cases, while light fastness values were medium to low. Ink-jet ink formulations were prepared using the ultrafiltrated dyes UF RR(a-c) and their properties pH, conductivity, surface tension and viscosity were monitored over a period of 90 days. The inks were used to print digitally cotton and nylon 66 samples and wash- and light fastness properties of the prints were measured. Wash fastness properties were excellent while light fastness values are low Colour measurements of the dyeings and prints were conducted.
