Rayon is still incredibly toxic to produce because of the process.

How so? Carbon disulfide is rather nasty, but it's straightforward to recover most of it. TLV is 10 ppm, while the effluent air from Teepak is 100 ppm [0], meaning you could spend hours a day with just over a 10:1 dilution of the factory exhaust. And there are lots of efforts to get those emissions way lower.

If it means less microplastics, I'm all for it.

Tencel brand is a closed-loop version of the lyocell rayon process.
