“…The cotton dyeing process with the natural dye, curcumin, was simulated with an initial concentration of 1 kg/m 3 at a temperature of 70 • C. It was used as an adsorption isotherm that, based on the studies of Haque et al [21], has higher performance in dyeing. The simulation was carried out with the parameter values in Table 2, in a time interval of 1800 s (30 min), considered for the exhaustion of the dye solution and the subsequent comparison with the experimental data.…”

“…The simulation results are obtained through approximate data based on the validation parameters of the process with the reactive dye and experimental parameters with a slight difference in the conditions of the dyeing process. With this clarification, a comparison was made between the results obtained and the experimental results of Haque et al (2018) of the dyeing of curcumin in cotton fiber.…”

Cotton dyeing is a very complex process with many variables in which different phenomena occur simultaneously. This study aimed to describe the cotton dyeing process by natural dye, using a mathematical model that consists of three mass conservation equations that depict dyeing cotton in cones, taking a representative volume element at the micro, meso, and macroscales. The first equation describes the concentration changes of the dye in the solution, taking into account the diffusive, convective, adsorptive, and reactive effects. The second equation describes the changes in dye concentration in cotton fiber, considering the diffusive, adsorptive, and reactive effects within an intermediate scale. The last equation describes changes in the concentration of dye in the solution on the macroscale, based on the characteristics of the equipment and the difference in concentration before and after passing through the fiber. In addition, a fluid continuity equation was incorporated, taking into account Darcy’s law. In the simulation of the dyeing process with synthetic dye with initial concentrations of 0.408 and 2.06 kg/m3, RMSE of 0.00221 and 0.0289 kg/m3 were obtained, respectively. For the simulation of a dyeing process with natural dyeing, a behavior similar to the experimental data was obtained.

Adsorption and desorption studies were done of polyhexamethylene biguanide (PHMB) onto two different types of textile fiber surfaces. Based on these studies and mathematical modelling, the rate constants were calculated. Two different experimental conditions were used to simulate laundering, namely wet-to-wet and dry-to-wet. The model PHMB surface concentrations showed that the model can be used to describe the adsorption kinetics on cotton and cotton-polyester blends with reasonable accuracy.
