説明
The diffusion of 1:2 metal complex dyes into biaxally drawn nylon 6 film from an infinite dyebath has been studied by the film roll method. The concentration profiles of the dyes in nylon were found to be Fickian, i.e. the diffusio_??_ coefficient calculated was concentration independent. Furthermore, changes in dyebath concentration in a between 1.5×10-5mol/l and 3.5×10-4mol/l had no effect on both the shape of Fickian profile and the pentration distance at a given time. It is concluded that the dyes in the polymer do not interact solely with the terminal amin endogroups in the nylon.<br>Using the surface concentration (equal to equilibrium adsorption) calculated from the profiles, the adsorption isotherms wa found to be curvature like Freundlich type. A possible explanation on the isotherm and the interaction between polymamide and the dye was made. The activation energy of diffusion in a temperature range from 75°C to 90°C was about 25kcal/mol.
