Abstract

Six cotton cultivars represent the two Egyptian cotton categories, i.e. extra long staple length (Giza 45, Giza 70 and Giza 88) and long staple (Giza 80, Giza 83 and Giza 89) were used in this study. From each cultivar representative samples of fibers of four grades (maturity% levels) (FG, G, FGF and GF) were dyed with direct and reactive dyes before and after mercerization treatment. The results obtained revealed that differential response between different varieties to dyeing with the dyestuffs utilized in this study. The color strength (K/S) values were the highest when the reactive dyestuff was applied, and followed in descending order by direct dye. Regarding the grades, fully good grade (FG) showed the highest color strength (K/S) value followed by good grade (G), fully good fair grade (FGF) and good fair grade (GF) respectively for mercerized and un­mercerized samples. It is worthwhile to mention that, mercerization treatment increase the dye ability and improve the properties of the samples especially the low grades. The color strength (K/S) values of mercerized fully good faire grade (FGF) increased more than that of the color strength values of un-mercerized fully good grade (FG) of Giza 70, Giza 83 and Giza 89 and nearly equal to Giza 45, Giza 88 and Giza 80 cultivars.
