Abstract

Abstract: Large amount of water is utilized in the textile dyeing and finishing processes and

as a result of that, the treatment of this large amount of effluent creates cost and very important

as the textile wet processes are concerned. In the last two decades, new technologies have been

utilized in order to minimize the processing time, energy consumption, water consumption and

le dyeing

and finishing industry and may include the following emerging technologies:

use of ultrasonic energy in textile dyeing and finishing,

use of microwave energy in textile dyeing, drying, and dye fixing,

use of plasma technology in textile dyeing and finishing,

use of supercritical fluids in textile dyeing and cleaning,

use of ozone in bleaching of textiles and also in the treatment of dyeing effluents,

use of combined enzymatic processes in the pre-treatment of textiles,

use of the Dyebath Reuse technology to minimize the amount of water to be used,

reuse of recovered chemicals and dyes from processes and

reuse of decolorized effluent in dyeing and finishing.

This current work will review the recent technology used in the textile wet processes with a

particular emphasis on the work carried out in the Turkish textile industry.
