I recently heard a podcast episode on plasma, where they mentioned that one of the major applications of plasma physics today is the coating of fabrics, for example for producing rainproof jackets.
What bugs me about it: how do they do it? If the temperature is high enough to turn the atoms of the coating material into plasma, it should be hot enough to also turn the base fabric into plasma.
I tried searching online for videos of how they do it, but only found a handful of PR videos for companies doing the coating, which tended to showcase the water-repellent effect of the finished material, or show people walking around a spruced-up factory. They never showed how it actually works.
So, what is the process behind it, and why does it work? How can we have plasma and a solid object meet, while keeping the solid object intact, such that it even keeps its original structure (in this case, its weave)? And how is it different from applying the same coating material as a gas, without the need to heat it until it has turned into plasma?
