| | The numbers at the individual dye fastness data mean:
| | First number
| - change of shade
| | Second number
| - staining of the undyed adjacent fabric made of the same material as the tested SAMPLE
| | Third number
| - staining of the undyed woolen adjacet fabric
| |
|
|
| | For the fastness to washing at 95°C and fastness to peroxide bleaching the figures have the following meaning:
| | For dyeing of cotton
| | First number
| - change of shade
| | Second number
| - staining of the undyed adjacent cotton fabric
| | Third number
| - staining on the undyed adjacent viscose fabric
| |
|
|
| | u vybarvení na viskóze

| | Second number
| - staining on the undyed adjacent viscose fabric
| | Third number
| - staining of the undyed adjacent cotton fabric

|
|
| | For fastness in mercerizing asterixat the figure means effect to deeper shade
| |
|
|
| | 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 equation
|
|
| | β
| jis 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.
