Scientists develop fabric cooler than cotton under direct sunlight
Researchers from Zhengzhou and Adelaide universities have created a purple fabric that stays significantly cooler than regular cotton in direct sunlight.
Key Takeaways
AIResearchers at Zhengzhou University and the University of Adelaide have developed a purple fabric that remains noticeably cooler than ordinary cotton when exposed to direct sunlight.
According to Sputnik, citing the journal Russia Science Portal, the new fabric was found to be 4.2 degrees Celsius cooler than white cotton and 6.2 degrees cooler than traditional purple cotton during outdoor tests.
The scientists explained that an effective cooling fabric should reflect as much solar energy as possible, while colored materials typically absorb specific wavelengths to produce their color.
The new fabric achieves two useful functions: it limits the amount of solar energy absorbed and efficiently releases heat. This combination explains how a colored fabric can remain unexpectedly cool even under direct sunlight.
