I see all sorts of answers online, but am not fully convinced. I tried finding some research on the longevity of clothes between wash and wash + dry. Considering that it dries for hours just the mechanical movement should damage the clothes I would assume?
By rules of physics it will damage it. Its rubbing against other clothes, its getting blasted with heat and it’s getting folded/bended over and over.
Damage is dependent on the material, but dor sure it wears them down.
