ELI5: Why are towels soft after they're dried in a dryer but kinda crunchy when left to air dry?

Move a crunchy air dried towel around enough and you'll eventually make it soft. This is because moving unsticks fibers that dried together.

A dryer is constantly moving so fibers don't have much of a chance to stick together. Or if they do they'll eventually unstick.
