In this work, the substitution of environmentally harmful additives in the industrial dyeing process of polyamide-6 microfiber-made knitted fabrics (PA-6µFKF) was studied. Using the disperse red 60 (DR60) dye, kinetic adsorption tests on the PA-6µFKF dyeing were performed by using either β-cyclodextrin (β-CD) additive, commercial leveling agents, or without additives. Equilibrium tests were also performed during 25 h. A modelling based on a dye adsorption process controlled by an intraparticle diffusion was proposed to represent the sets of kinetic data. Three isotherm models were also tested for representing the equilibrium data. The kinetic data have evidenced three main dye diffusion zones. Different adsorption mechanisms on PA-6µFKF surface dyeing was evidenced, being the data well represented by the two-step Langmuir isotherm. Finally, the best quality on color uniformity was attained using the β-CD additive, revealing a good alternative for the substitution of environmentally harmful additives in industrial dyeing processes.

在这项工作中，研究了聚酰胺6超细纤维制成的针织面料（PA-6µFKF）在工业染色过程中对环境有害的添加剂的替代方法。使用分散红60（DR60）染料，通过使用β-环糊精（β-CD）添加剂，市售流平剂或不添加添加剂，对PA-6µFKF染色进行动力学吸附测试。在25小时内也进行了平衡测试。提出了一种基于受粒子内扩散控制的染料吸附过程的模型，以表示动力学数据集。还测试了三个等温线模型以表示平衡数据。动力学数据证明了三个主要的染料扩散区。证明了对PA-6µFKF表面染色的不同吸附机理，这是两步Langmuir等温线很好地代表的数据。最后，
