“…The products derived from the coupling reactions of the two amines ( Figure 1) with a molar ratio 1:1 are new monoazo reactive red dyes. The synthesis is in accordance with previous experimental data [15] while previous work [6] containing coupling of the amines with a molar ratio 1:2 resulted in disazo reactive blue dyes. Table 1 shows the melting points, the spectrophotometrical data UV-Vis and FT-IR and the elemental analysis of the dyes.…”

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.

Reactive dyes are widely used in the textile industry due to their versatility of shades, high wash fastness properties, and the ease of application. Dyeing properties such as exhaustion, substantivity, fixation, time to half dyeing, migration index and effect of metal salts were studied for a novel reactive dye (named RRNa) synthesized with one vinylsulfone as reactive group. The aim of this study is to figure out the influence of the ultrafiltration process this dye went through on its aforementioned properties. It was found that the ultrafiltrated reactive dye shows higher exhaustion, substantivity, dye uptake than the original dye, which is attributed to the purification performed by the ultrafiltration process. The migration index is slightly lower for the ultrafiltrated dye which indicates that its mobility is lower, due to the possible formation of more covalent bonds between the dye and the substrate. The effect of metals (Fe, Co, Cu) was also studied and the color strength of the dyeings in the presence of sulfate salts was compared with the control sample. It was found that Co2+ and Cu2+ have a detrimental effect on the shade obtained, whereas Fe3+ reduces color strength to a lower extent.
