New T-shirt Fabric Can Keep Your Skin Cool

Chinese Scientists Claim This New T-shirt Fabric Can Keep Your Skin Cool

WHAT’S BEING CLAIMED:

  • Chinese scientists have designed a fabric that can help people keep cool in the sweltering heat.
  • The fabric uses technology that absorbs heat and emits it into space. 
  • According to the researchers, the fabric can be mass-produced at a minimal additional cost. 

Chinese scientists have devised a way to help people cope with the rising temperatures by designing a T-shirt fabric that can keep the skin cool.

According to the scientists, the fabric can be mass-produced at only a minimal additional cost, which will be extremely helpful for outdoor workers or beachgoers to keep cool in increasing temperatures.

Regular clothing usually uses fabric that reflects near-infrared electromagnetic radiation (NIR). But when water vapor in the air absorbs near-infrared electromagnetic radiation (NIR), it can keep the surrounding air temperature high. 

The human skin emits electromagnetic radiation called mid-infrared (MIR), which goes directly out of our atmosphere instead of being trapped in water particles. 

Chinese scientists Ma Yaoguang of Zhejiang University and Tao Guangming of Huazhong University of Science and Technology designed a synthetic fiber blend that uses technology to absorb body heat and emit it as MIR to keep the wearer feeling cool.

  

The image above shows the trial results. During the trial, a participant wore a vest that was half white cotton (left part of the image) and half the cooling fabric (right). Using thermal imaging, researchers found that the part of the body underneath the cooling fabric remained 5°C (9°F) cooler after an hour of sun exposure.

However, Science reports that there are some doubts about how the motion of fabric will affect the shirt’s mechanisms, as MIR-emitting materials have only been tested when laid flat and motionless under the sun. A person’s curves in the shoulders and arms may affect how the cooling fabric may work under the sun.

According to the scientists, producing the fabric only costs about 10% higher than cotton.
