Case Study

Kinetics of Dyeing Nylon Fabrics with Acid Blue 182

Sada E, et al. Journal of the Society of Dyers and Colourists, 1986, 102(3), 105-109.

The kinetics of dyeing nylon fabrics with an acid dye (C.I. Acid Blue 182) was studied using a rotating disk contactor. The analysis was performed based on intra-polymer diffusion of adsorbed three peaks (one Nernst type and two Langmuir type).
· Nylon film and fabric were dyed with C.I. Acid Blue 182 in a rotating-disccontactor at pH 2.1 and 80°C.
· The resistance to mass transfer from liquor to film was found to be negligible relative to resistance to diffusion inside the nylon film.
· The process of dyeing of nylon fabric is governed by diffusion in the void between filaments within the yarn from which the fabric is made, and the effective interfilament diffusion coefficient is increased with increasing strength of flow at the surface of the fabrics.
· The process can be modelled in terms of diffusion in liquid-filled pores between filaments, with the existence of adsorption equilibria within the filament substrate. In this case the resistance to mass transfer from liquor to fabric cannot be eliminated at low values of Reynolds number (e.g. Re<3500).
