In this work, the substitution of environmentally harmful additives in the industrial dyeing process of polyamide-6microfiber-made knitted fabrics (PA-6μFKF) was studied. Using the disperse red 60 (DR60) dye, kinetic adsorption tests onthe PA-6μFKF dyeing were performed by using either β-cyclodextrin (β-CD) additive, commercial leveling agents, orwithout additives. Equilibrium tests were also performed during 25 h. A modelling based on a dye adsorption processcontrolled by an intraparticle diffusion was proposed to represent the sets of kinetic data. Three isotherm models were alsotested for representing the equilibrium data. The kinetic data have evidenced three main dye diffusion zones. Differentadsorption mechanisms on PA-6μFKF surface dyeing was evidenced, being the data well represented by the two-stepLangmuir isotherm. Finally, the best quality on color uniformity was attained using the β-CD additive, revealing a goodalternative for the substitution of environmentally harmful additives in industrial dyeing processes.
