Abstract
This research work involves a comparative study on tinctorial and fastness properties of cotton and modified cotton fabrics dyed with date pits powder using conventional and ultrasonic energy. The dyeability of non-modified cotton fabric has been just succeed in acidic medium. For modified cotton fabric, the extracted dye has presented an affinity via the textile fabrics at acidic and basic medium. It was also to note, that in all the studied cases the ultrasonic treatment has presented a highest dye uptake when compared with the conventional one. The overall fastness properties were evaluated and all the dyed samples have presented, generally, good fastness properties. Also a comparative study of the hydrophilic character of cotton, modified cotton and commercially cationized cotton has been developed, and it was shown that the modification of cotton doesn't affect enormously the hydrophility of cotton when compared with the commercially cationized cotton.
