The Indian Institute of Technology (IIT), Ropar has created a brand-new, cutting-edge green technology called an air nano bubble that can reduce water use in the textile industry by up to 90%, according to reports.
According to sources, the technology is based on ozone and nanoscale air bubbles. Due to their hydrophobic character, the bubbles interact with the cloth more favorably than water and disperse chemicals and dyes in the fabric more effectively.
Neelkanth Nirmalkar, Assistant Professor at the chemical engineering department of IIT, Ropar developed this technology.
As per Neelkanth, “The air nano bubble dispersed in water can reduce the water consumption and chemical dosage by 90-95 per cent which ultimately saves 90 percent of the energy consumption as well.”
The bubbles are of a size equivalent to 1/10000th times of a human hair. Ozone nano bubbles efficiently remove extra dye during fabric wash and degrade the dye in the water, he added.
In addition to reducing water consumption, a nano bubble machine’s processed water can be recycled. According to him, nanobubbles act as a carrier for the processing chemical and cut down on the amount of additional chemical needed.
He also claimed that the treatment of garments through this patented technology helps in maintaining their real colour for outdoor usage. It helps in obtaining 2D effects, easy care, water repelling and softening of fabric.
Regarding this, Rajeev Ahuja, Director, IIT Ropar said, “We are inventing and incorporating new-age processing methods to conserve water for future generations.”
Notably, IIT Ropar has developed this eco-friendly technology under a start-up named NanoKriti Pvt Limited, which is also working towards cleaning the environment and is expanding to develop new applications, ranging from water treatment to healthcare.
