The behaviour of two surface–active agents (anionic and cationic) in the dyeing of Hercosett wool with reactive dyes of the α–bromoacry/amide type has been studied. The influence of pH, concentration of dye and surface–active agent, temperature and time on the percentage of the dye adsorbed and reacted is studied. Due to the complexity of this subject, a central rotatable plan of five variables has been used. The results found are represented in three–dimensional graphs, and are examined through the possible mechanisms that operate in the dyeing process, considering the nature of the anionic and cationic agents used.
