Advantages of solvent dyeing:
1) Effluent control & treatment problems have been eliminated.
2) Rapid dyeing is possible with minimum energy consumption.
3) Better levelness and dye yield coupled with better fabric aesthetics.
4) Solvent can be recycled and reused.
5) Solvents require lower temperature lesser time for some shades that compares to water.
Disadvantages of solvent dyeing:
1) Higher cost of solvents. Again, 100% solvent recovery is not possible.
2) Problems in equipment availability.
3) Existing dyestuffs cannot be reused in full range.
4) All fibres are not suitable for solvent dyeing. Only man made hydrophobic fibres can be dyed
