The Effect of Carriers on the Dyeing of Courtelle S

The extent to which the uptake of C.I. Basic Blue 3 on Courtelle S tow was enhanced by three derivatives of benzyl alcohol was found to be proportional to the amount of each carrier adsorbed by the fibre, with maximum dye uptake coinciding with maximum uptake of carrier by the fibre. Although the maximum extent of uptake of each carrier corresponded approximately to the aqueous solubility of the carrier at the dyeing temperature (80 °C) used, results from a previous study on the carrier action of benzyl alcohol on Courtelle S was employed to demonstrate that maximum uptake of all four carriers was not simply related to aqueous solubility
