| Summary: | The equilibrium sorption of dyeing polyamide 6.6 fabric with reactive dye is presented in this paper. Polyamide is a chemical fiber obtained from synthetically produced polymers, while reactive dyes are most often sulfonated azo compounds: which are derived from bendisidine and its derivatives. The solution in a constant volume contained dye concentrations of 5, 10, 15, 20, 30, 40 and 50 mg/L. The samples were dyed at temperatures of 40, 60 and 98°C. A spectrophotometer (Cary 100 Conc UV-VIS, Varian) was used to measure the absorbance of aqueous dyed solutions and to calculate the unknown dye concentration in the solution and to construct a calibration curve. The degree of dye exhaustion and the amount of absorbed dye were calculated. Two models of adsorption isotherms were used: Freundlich and Florry-Huggins. The high functionality of the variable was observed in the Freundlich model. |
