Solvent Assisted Dyeing of Acrylic Fibres. Part 2 – Dyeing With Disperse and Cationic Dyes

The plasticising solvents ethylene carbonate, propylene carbonate, nitromethane and iso-amyl alcohol have been added to aqueous dyebaths containing disperse and cationic dyes. The dye uptake in all the cases was found to increase linearly with decrease in the glass transition temperature of the acrylic fibres
