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  |
