Theories and mechanisms of dyeing

Theories and mechanisms of dyeing According to thermo-dynamical behaviour, the fixation of a dye molecule liberates heat energy and shows substantivity with the fibre in case. Possibilities for the fixation of dye molecules are physical adsorption (H-bonds, v.d.Waals bonds), chemical reaction (covalent bonds, ionic bonds), and mechanical retention (blocking in pore/fibre structure). The bond formation
