The International Exhibition of Inventions Geneva is the world’s largest annual event devoted exclusively to inventions and the licensing market.
Natsu Cool is a single-use non-woven facemask that has incorporated the “cooling” function by adopting a structural design to avoid heat buildup and surface-coating with heat dissipating materials. It has a 4-layer stereo design of an optimised three-dimensional breathing zone, and the additional fabric layer is further coated with a mixture of hygroscopic cooling agents, sugar alcohols, by using binder-free fabric surface modification technology.
