They did, but they were not writing about clothing production for the most part. This we lack insight into what they did except what we can make educated guesses on.
We can date archeological finds accurately enough the the word guess is not appropriate. I know that sewn clothes have existed something like 20,000 or 30,000 years. And I think I read recently about woven fabrics dating back maybe 8 thousand years or so. I tend to think in round numbers so go ahead and call that a guess, but archeologists have this stuff dated pretty accurately. And new finds sometimes push the dates back even further.
