  ABSTRACT: Nylon 6 fabric was dyed with C.I. Acid Yellow 23 at a temperature 50°C using sodium chloride (NaCl) and citric acid as auxiliaries. The adsorption kinetic mechanism was studied using two models. Results of the UV-Vis spectroscopy indicated that colour yield of C.I. Acid Yellow 23 reduced when more than 1% (acid) and 5% (salt) concentration were used respectively for dyeing. NaCl however had the most inhibitive effect on the dye colour yield. The adsorption kinetics mechanism result fitted the pseudo-second-order-kinetic model with R2 of 0.993.
