Anionic reactive dyes used to dye nylon suffer from failures due to the poor efficiency caused by low degree of exhaustion and fixation. From the previous work , the dyeing efficiency of Procion Rubine XL on modified nylon was particularly week and hence offers the widest scope for an in depth investigation in to variables that effect the dyeing process. The variables dyeing studies for this pr...

Abstract In recent days, the waste productions from industries are increased and direct discharge of wastes causes various pollution to environment. Wastewater treatment in textile dye industry mainly involves highly colored wastewater containing variety dyes different concentrations. The dyeing using types pigments concentration during their several production steps. These a which contains org...

As increasing attention is being paid to harmful residual dye pollution in the dyeing effluent from microfiber synthetic leather industry, there an urgent need explore innovative ways alleviate such pollution. Here, a low-polarity waterborne polyurethane (WPU) was synthesized using hydroxyl-terminated polybutadiene (HTPB) and polypropylene glycol (N220) as soft segments react with –NCO on isoph...

A wide range of chemicals and dyes are being used in textile industry, and are often found in the wastewater produced. This study attempts to investigate the reduction of COD, TSS, and dye in effluents from the dyeing and washing unit of textile industry, using electrocoagulation process. The reactor is equipped with 10 iron electrodes, connected to a direct current (DC) source in a monopolar e...
