The Indian Institute of Technology, Ropar, has developed an innovative green technology air nano bubble that can reduce the use of water up to 90 per cent in textile . Nearly 200 litres of water is required to process 1 kg of Cotton fabric.
The laboratory reports suggest the air nano bubble dispersed in water could reduce the water consumption and chemical dosage by 90-95 per cent.
This ultimately also saves 90 per cent of the energy consumption, said Dr Neelkanth Nirmalkar, who has developed the technology.
In the textile industry, the water is used at many steps, including for dyeing, finishing chemicals in the textile substrates, desizing (process of removal of sizing material from yarn), scouring, bleaching, and mercerizing (chemical treatment of fabric to enhance affinity towards dye).
At the same time, the textile industry also produces the highest volume of waste water.
