The Chinese are developing a new type of fabric  that can make humans feel 15 percent cooler when they put the clothes on in hot conditions.  The technology is sure to be duplicable by others, and, hopefully, will be duplicated by those committed to open source technology that gives all of humanity the opportunity to develop and exploit this type of technology.

With China working hard to colonize Africa, one can see how a product such as this could be a billions of yuan winfall for the CCP-controlled corporations that produce such products.  It would be better for Africa to develop their own engineered silk products and produce them in-continent than to pin such a dependence to such a totalitarian and supremacist state as China.

Fabric technology: Modified silk keeps skin 12°C cooler than cotton

Climate change is making summer days even hotter for some – but new clothing might helps us keep cool

A fabric made of engineered silk keeps skin about 12.5°C cooler than cotton clothing and provides relief from hot weather.

Approximately 15 per cent of global electricity goes towards keeping us cool. To reduce this energy demand, scientists have been searching for passive ways of cooling us that don’t require electricity.

Jia Zhu at Nanjing University in China and Shanhui Fan at Stanford University and their colleagues were inspired by silk, which feels cool against the skin because it reflects most of the sunlight that strikes it – mainly the infrared and visible wavelengths – and so readily radiates heat.

They were able to engineer silk to block even more sunlight – about 95 per cent – by embedding the fibres with aluminium oxide nanoparticles that reflect the ultraviolet wavelengths of sunlight.
