As others have said, both washers and dryers let clothes tumble around uncontrollably for hours at a time which can do varying levels of damage.
My best unscientific advice from doing both a lot is to keep load sizes small. Reduces the friction and theoretically reduces the drying time, which also reduces damage. Also, if drying tshirts with ink prints, flip them inside out to protect the ink.



That’s exactly what I would say if I owned an LLM or LLM adjacent company
