Fundamental Mechanisms to contribute a dyeing
by : Rahul Sharma
Fundamental Mechanisms to contribute a dyeing:
- Control of the exhaustion dye so that it is taken up evenly.
- Migration of dye after initially unleveled absorption on the fibre.
- Non-ionic agent usually from water soluble complexes with the dye, some degree of solubilization being involved.
- Ionic agent are primarily dye-of fibre-substantive ; in the former case they tend to form complexes with the dye and there is competition between the leveling agent and the fibre for the dye, while in the latter case the competition is between the leveling agent and the dye for the fibre.
