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 5.7. The CEC varied from 43meq/g to
82meq/g. This study showed that the color yield and the dyeing fastness were improved for modified cellulosic
fabrics. The Bohem titration and FTIR spectrum showed that the acidic sites number on the fabrics increased after
using anionic agents.
