  In order to improve their affinity to the cationic dyes, cotton and jute cellulosic fibres were chemically modified using natural compounds such as: Tannic acid, Mimosa and cactus juice and commercialized compounds such as Clarite Com, Albatex and Albaflow. Cellulose modifications were performed using physiochemical analysis such as Bohem titration, spectroscopic analysis (FTIR spectroscopy and UV-Vis), the Point of Zero Charge (pHPZC) and the Cationic Exchange Capacity (CEC) determination. The dyeing performance were evaluated by controlling the percentage of the dye bath exhaustion (E %), the color yield (k/s), the brightness index BI (%) and the dyeing fastness to light, washing and rubbing. Two cationic dyes CI Basic Red 46 and CI Basic Blue 3 with a delocalised cationic charge were checked for dyeing properties. The pHPZC of modified samples varied from 2.98 to 5... Read More»
