Reusing protective clothing against droplet infections
The textiles under investigation are currently used for cleanroom clothing in satellite manufacturing, where they primarily protect the environment. For potential medical use, the fabrics were given a hydrophobic PTFE coating. This modification ideally prevents wetting by infectious droplets and their absorption so that they fall off or evaporate on the surface. The detection of such hydrophobic properties by means of contact angle measurement technology is fast, simple and can also be carried out on a mobile basis.
There is still a long way to go before medical facilities can switch to reusable protective clothing. But it is certainly worthwhile, not only for ecological reasons and in the event of supply bottlenecks. Doctors and nurses could benefit from more comfortable and breathable protective clothing.
