Application of 1:2 metal complex dyes on pre-cationized cotton has been studied. This unconventional process avoids the use of electrolyte required as exhausting agent in conventional dyeing of cotton fabric. Indeed, when we use a large amount of salt, the discharged wastewater from dye house creates unavoidable environmental threats. The dyeing has been carried out at the liquor ratio of 1:40 in a sealed stainless steel dyebath housed on the Ahiba Nuance speed varying temperature, contact time and sulphate concentration. Optimal conditions are determined using the experimental designs method. The results show the possibility of chemical auxiliaries free dyeing of cotton fabrics with 1:2 metal complex dye at 75°C for 15 min by treating them with cationizer prior to dyeing. Adsorption kinetic and isotherm are also studied and the parallel exponential model is shown to fit experimental data with higher average regression coefficients. |
