I guess there's no use for paper fabric such as the ones you had during WW1, as from my understanding that literally is woven paper thread. Given that I couldn't find any mentions of "paper fabric" from WW2, the technology was probably dated by that time and turning cellulose into viscose was a better option than the paper thing at the point. I do know for a fact that late German uniforms were more viscose than wool and cotton.
Also, I thought paper can be turned into viscose, but its dont, so WW2 viscose was from food, not paper.

Seems that by WW2 the paper proper was only used for fake leather.
Makes me want to understand the process behind the WW1 paper textiles they made clothes from, and why it wasn't used or wasn't widespread by 1940s, but there's little comprehensible info online, as well as any accounts on how these clothes wore/felt.
Pls no bully.
Hair is a "renewable source", so it's yucky but still ethical, it's not dehumanizing like human leather.
Burying people is a perfectly fine use of resources, it feeds the Earth.
