The aim of the current investigation is the synthesis, characterization, application and evaluation of dyeing performance of novel acid dyes derivatives.
Acid dyes are chemically a sodium (less often ammonium) salt of a carboxylic or phenol organic acid, or sulfuric acid, with ionic substitution to be soluble in water and contains affinity for amphoteric fibers, while lacking direct dye affinity for cellulose fibers (via hydrogen bonding, Van de Waals, and ionic bonding) [67, 68].

In the present research project Almond oil cake and cotton seed oil cake are used for removal of acid dyes (EBT) and A-FGGL bluerespectively from aqueous solution.
Acid dyes are mostly organic sulphonic acids, which are commercialized usually in the form of sodium salts for increasing their water solubility.
The special system is able to avoid color changes of selected acid dyes till a concentration of 0.3% active chlorine.
Reactive dye classes include trichloropyrimidine, mono-chlorotriazine (MCT), car- oxypyridino triazine, dichloroquinoxaline, monofluoro- triazine,difluoropyrimidine, difluorochloro- pyrimidine, and phosphonic acid dyes. Reaction between the dye and cellulose can occur when the dye has been absorbed into the cellulose phase.
Summary: We report synthesis and performance evaluation of a series of novel acid dyes based on diazotized substituted aryl amines and employing substituted naphthalene sulfonic acids as coupling component.
