Abstract
The levelness of modified and unmodified Egyptian cotton made from Giza 89 fabric 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 calorimetrically. 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. The results obtained revealed that levelness of dyeing's of CI Direct Blue 78 and CI Direct Yellow 106 on unmodified cotton was slightly improved by the surfactants Rokamin 11 and Igepal CO720. On modified cotton (grafted and quaternised). When dyeing with CI Direct Blue 78, the changes in levelness was achieved for only a "slight decrease in exhaustion, on the other hand, either of the two surfactants, an improvement in Ievelness was also observed, and consequently both surfactants can be used as effective levelling agents, with Igepal CO720 giving better exhaustion results.
