Summers are approaching and what would be better than having your own clothes that keep you cool? Scientists at the University of Alabama at Birmingham in the United States are working on innovations and have also applied for a patent. The research team led by Dr Vinoy Thomas, who is a native of Valakam in Kottarakkara. The findings have been published in the journal of the American Chemical Society. What Is The New Finding Of Self-Cooling Fabric?The researchers did not create a brand-new cooling fabric. Instead, they introduced a technique that transforms regular textiles into heat-regulating materials. This is done using two processes: electrospinning and plasma surface modification.The first technique allows boron nitride nanoparticles to be evenly spread across the surface of the fabric. The second method uses low-temperature plasma (LTP) treatment to embed silicon oxide nanoparticles into the stitching threads.Both boron nitride and silicon oxide are known for their heat-resistant qualities. By combining these two methods, researchers have created a coating that significantly lowers heat. The nanoparticles act as an added protective layer on the fabric.Testing showed that the coating remains effective even after five to eight washes and does not affect the fabric’s original properties. Although its performance gradually decreases with repeated washing, researchers suggest applying a double-layer surface coating to improve durability.Commercial production is expected to start once the patent is approved. In experiments, the coated garments reduced an external temperature of 35°C by 15°C, lowering it to 20°C. According to the researchers, this technique can be applied to any type of fabric.Unlike earlier studies that focused on inventing entirely new heat-resistant materials, this innovation modifies existing fabrics. The study states that this approach is more efficient and cost-effective than current technologies.The research team also includes Dr Ranjith Rajanpillai, Dr Kannadasan Appavu, Dr Claudiu T Lungu, and Dr Sanjay K Behura from the Department of Mechanical and Materials Engineering.Innovations For Sizzling SummersIn Japan, something similar happened when former Sony engineer Hiroshi Ichigaya came up with kuchofuku or "fan jackets". This garment has a built-in feature, powered by battery, which is a fan at the lower back. This helps the circulation of air and to evaporate sweat and cool workers. These jackets are commonly used by construction workers, delivery partners, and people working in factory to combat extreme heat.
