| Abstract: | Acrylic fibre has been dyed with Rhizoma coptidis aqueous solution and its dyeability is studied in terms of the thermodynamic and kinetic properties and dyeing conditions. The results show the Langmuir type adsorption isotherm for dyed acrylic fibre. The dye uptake and dyeing diffusion coefficient of acrylic fibres increase with the increase in dyeing temperature. The effects of dyeing conditions such as dye concentration, dyeing temperature, dyeing time, pH value of dyebath and mordant dyeing on color characteristics of the dyed fibres have been studied, and the optimal dyeing process is selected by orthogonal experimental. The results show that the dyeing temperature and mordant content are the most important influencing factors. Wash fastness and rub fastness of the dyed acrylic show above 4 grade. |
