IIT Delhi develops modified cotton fabric

New Delhi

Modified cotton fabric has been developed by the researchers at the Indian Institute of Technology (IIT) Delhi which is capable of adsorbing harmful air pollutants.

These fabrics are commonly known as ZIF-8@CM Cotton and ZIF-67@CM Cotton. They fall under Zeolite Imidazolate Framework (ZIF)-modified functionalised fabrics because they can absorb high levels of organic air pollutants that include aniline, benzene, and styrene from the air. The research team feels that pollution that is caused due to the increasing levels of sulphur dioxide, carbon oxides, and nitrous oxides other toxic volatile organic compounds is a big issue. The presence of these particles in the environment takes a toll on the health of people and can cause eye problems, throat infections, and even asthma.

According to Ashwini Agrawal, the Textile and Fibre Engineering Department, IIT Delhi, with the help of this study, the team has tried to show the functionalization of cotton fabric by ZIF MOFs (ZIF-8 and ZIF-67) using a rapid, eco-friendly, scalable, and facile approach. These fabrics can control gaseous pollutants that cannot be filtered using filter media, he said. These are perfect for closed spaces like offices, homes, theatres, airplanes, and other vehicles, he added.

These fabrics can also withstand the harsh conditions of washing. They can also be used to design functional filters and pollution-controlling fabrics. They can be regenerated by heating at 120 degrees Celsius and can be reused.
