Difference between
Dye Affinity & Dye Substantivity
Dye Substantivity
|
Dye Affinity
|
Natural attraction between dye molecule and fibre is called dye substantivity.
|
Attraction between dyes and fibres with dyeing conditions is called dye affinity.
|
The dye molecules transfer from dye bath to textile materials without any dyeing conditions.
|
The dye molecules transfer from dye bath to textile materials in presence of heat or temperature.
|
Substantivity varies with van der Waals and dispersion force between the dye and fibres molecules
|
Affinity varies with the temperature |
