A cheap shirt to cool the body may dispense with the conditioning
Researchers at two Chinese universities have created an inexpensive T-shirt to cool the body, based on the properties of infrared radiation emitted by human skin in a medium range.
According to the Jordan News Agency, Petra, (Science) magazine indicated that researchers based on the experience of their colleagues at Stanford University in the United States, who, five years ago, created a fabric of nanoparticles, 0.045 millimeters thick, that can reduce body temperature by 3 degrees Celsius But the durability of this fabric has raised doubts about its use.
Chinese researchers from Georgian and Hua Zhong Universities of Technology decided to create a thicker and more durable fabric, and were able to create a tissue from a mixture (polylactic acid), with nanoparticles of titanium dioxide, its thickness (0.55 millimeters). This tissue absorbs the infrared rays emitted by the body and releases it to the surrounding environment. It also reflects the ultraviolet rays, and tests showed that it reduces the temperature by five degrees Celsius.
“Although this fabric looks like a regular shirt, visually it is a mirror,” says one of its creators, engineer Tao Guangming.
"We can mass-produce the new fabric, and this means that anyone can get a shirt from it for the price of a regular cloth shirt," he adds. The magazine said that the American Stafford University scientists, following the successes of their Chinese colleagues, decided to test the Chinese fabric themselves, and whether it reduces the temperature while walking as well.
