Saturation and Exhaustion Curves
Saturation curves express the dyeing saturation in dependence on the increasing dye concentration in the dyebath. From them it is possible to determine the saturation point of the dyestuff, i.e. the maximum effective dye concentration. On the X axis there are assigned the integrated reflectance „I“ values
Where K/S is the Kubelka -Munk œ equotion
is surface reflectance
are the colour matching response functions for the D65 light and 10°standard observer
Exhaustion curves were designated from initial concentration of 1/1 standard depth by standard exhaustion method and show the amount of the dye exhausted from the dyebath in dependenc on the dyeing time.
