Types of Fabrics
Have been subconsciously ignoring looking into all fabrics that exist. Finally looked into the matter, here's what it comes down to:
All fabric fundamentally comes from plants and animals. Used as they were found, it is termed 'natural fabric'. This is the way humans always clothed themselves - sustainable and healthy in every way possible. If you process it, it's semi-synthetic. Invented in the 1890s, not as sustainable. If instead of sourcing from plants and animals alive today, you source it from those dead millions of years ago, aka from fossil fuels, that's the third category - synthetic. Basically plastic. Bad for everyone in every way. Only good if pitched against staying naked.
Wear natural fabric.
