U.S. researchers have created a fabric that will help survive the heat

Researchers from the Pritzker School of Molecular Engineering (PME) at the University of Chicago have developed a new fabric. It can help urban dwellers survive the worst effects of heat and can be used in clothing, construction and car design, as well as food storage.

In an article published recently in the journal “Science”, researchers claim that the new textile reduces heat both from the sun and from thermal radiation from nearby buildings, writes Fibre2Fashion.

During tests under the Arizona sun the material was 2.3 degrees Celsius cooler than broadband emitting fabric,used for outdoor endurance sports, and 8.9 degrees Celsius cooler than commercial silk, which is commonly used to make shirts, dresses and other summer clothing.

This, the team hopes, will help many avoid the heat-related hospitalizations and deaths seen around the world this year.

The available cooling fabric for outdoor sports works by reflecting sunlight in a diffuse pattern to prevent dazzle the audience. But in the conditions of the urban heat island, the sun – only one heat source, others are thermal radiation from buildings, road surfaces and vehicles.

This means that many materials that perform well in laboratory tests will not help urban dwellers in hot places.

Sunlight and pavement heat up differently. Creating one material capable of protecting people from both of these factors became a serious engineering challenge for the team.

Sunlight – this is visible light, and thermal radiation – infrared, so they have different wavelengths. This means that you need to have a material that has two optical properties at the same time. It is very difficult to do,
– said co-first author Chenxi Sui, a PME graduate student, in a university press release.

“You have to play around with materials science to design and tune the material to give different resonances at different wavelengths,” – he explained.

The new textile, which received a preliminary patent, could help provide a passive cooling system that could complement and reduce the need for energy- and waste-intensive systems.

Similarly, the material could be used to transport and store milk and other products that would otherwise spoil in the heat, reducing the effect of refrigeration equipment.
