WD News: The Indian Institute of Technology, Ropar has said that it has developed an innovative green technology – air nanobubble – that can reduce the usage of water in the textile sector by up to 90 percent.
“Textile is one of the most water-intensive industries and there is an escalating need to address the problem of managing water usage in the textile industry associated with contamination of water,” Mr Rajeev Ahuja, Director, IIT Ropar said in a statement.
Neelkanth Nirmalkar, who has developed this technology, said that as per a rough estimate, 200-250 litres of water is required to process one kg of cotton fabric.
The laboratory reports suggest that the air nano bubble dispersed in water can reduce the water consumption and chemical dosage by 90-95 percent which ultimately saves 90 percent of the energy consumption as well, Nirmalkar claimed.
In the textile industry, water is used in many steps required for fabric preparation, including for dyeing, finishing chemicals in textile substrates, de-sizing (the process of removal of sizing material from yarn), scouring, bleaching, and mercerising (chemical treatment of fabric to enhance affinity towards dye, the statement said.
