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 environmental problems. Therefore, the
“Green Production” concept is the first key issue as far 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 the amount of effluent. “Green production” is a preventive
business strategy in textile 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 “Direct 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.
