Engineers from the University of Chicago have developed a unique fabric that can cool surfaces and skin by up to 8 degrees in urban environments. The three-layer fabric is designed to block over half of the radiant heat emitted from buildings and the ground, making it an ideal solution for protecting clothes, buildings, cars, and even storing food.
The developers of the fabric aimed to create a material specifically for cities where surfaces like asphalt and buildings can radiate heat and raise temperatures significantly. The silver threads in the fabric reflect not only direct sunlight but also thermal radiation emitted by urban structures, effectively cooling the fabric and reducing heat absorption.
In a world where heatwaves are becoming more frequent and intense, this fabric’s cooling effect could have significant impacts on human health and comfort in urban areas. By reducing heat-related hospitalizations and even deaths, it could be a valuable tool in combating the effects of urban heat islands.
The fabric has been tested in outdoor conditions under the Arizona sun and remains significantly cooler than traditional silk fabric. Its unique design that incorporates different properties to reflect both direct sunlight and thermal radiation sets it apart from other cooling fabrics on the market. Additionally, its protective qualities make it suitable for a variety of applications beyond clothing, including building protection and food storage during transport.
