Separation Of Dyes From Cotton Dyeing Effluent Using Cationic Polyelectrolytes
The separation of reactive, sulfur, and vat dyes from cotton dyeing effluent was investigated by a coagulation process using a cationic polymer electrolyte (PE). The coagulation of dyes was found to be considerably influenced by the amount of added PE and pH of the effluent. High degree of separation, (i.e.-90-99%) could be achieved for all the dyes. The secondary treatment of the PE treated (p...
متن کاملSalt-free dyeing of cotton fabric modified with prepared chitosan-poly propylene imine dendrimer using direct dyes
This study presents a novel method for eco-friendly dyeing of cotton fabrics with direct dyes. Cotton fabric modified with chitosan-poly propylene imines dendrimer CS-PPI, and its dyeing and fastness properties were investigated using three direct dyes. The impacts of important factors, i.e., CS-PPI concentration, dye concentration, dyeing time, dyeing temperature, and salt concentration were i...
متن کاملTreatment of a Textile Effluent from Dyeing with Cochineal Extracts Using Trametes versicolor Fungus
Trametes versicolor (Tv) fungus can degrade synthetic dyes that contain azo groups, anthraquinone, triphenylmethane polymers, and heterocyclic groups. However, no references have been found related to the degradation of natural dyes, such as the carminic acid that is contained in the cochineal extract. Experiments to determine the decolorization of the effluent used in the cotton dyeing process...
متن کاملDyeing of Cotton Fabric with Natural Dyes Improved by Mordants and Plasma Treatment
Nowadays, there is a great tendency for eco-dyeing and finishing of textiles with natural products. several natural dyes have been used for dyeing of protein fibers but a low number have the ability to dye cotton fiber because of low affinity of cellulose to the natural dyes. In this study madder and weld natural colorants were used to dye cotton fabric premordanted with three metallic salt...
متن کاملA Study of Physico-Chemical Properties, Exhaust Dyeing of Cotton with Synthesized azo-reactive Dyes and Their Printing Applications
Three sulfatoethylsulfone reactive dyes have been synthesized and were applied to mill desized, bleached and mercerized cotton fabric. Effect of different dyeing parameters i.e. salt concentration, dyeing time, dyeing temperature and pH of dye solution were being optimized by exhaust dyeing method. The fixation (%F) of the synthesized dye molecules with the cotton fabrics was also studied. Cott...
