Lyocell, commonly known by its trade name Tencel, is an eco-friendly type of rayon. It's produced using a closed-loop process, so fewer chemicals are used during its production, and they're recycled and reused.
Allowing printed garments to air dry naturally is one effective method, followed by a careful, low-heat ironing if necessary, making sure not to apply direct heat onto the print itself.
So you can go in all directions with rayon!
