The levelness of modified and unmodified cotton fabrics dyed with CI Direct Blue 78 and CI Direct Yellow 106 in the presence and absence of two nonionic surfactants (Rokamin 11 and Igepal CO720) was evaluated colorimetrically. The cotton was modified by grafting with vinyl pyridine (with and without quaternisation with dodecyl bromide). On modified cotton (grafted and quaternised) a significant improvement in levelness was achieved for only a slight decrease in exhaustion.
