Why do clothes feel crunchy when you air dry them, but soft out of the dryer?

Tap water has minerals dispersed in it in solution. When it dries on a line the fibers/threads stiffen because the clothing is not moving much, and the threads retain their shape as the water evaporates and leaves the minerals behind, while in a tumbling dryer the threads are constantly crunched and tugged and squeezed so they cannot stiffen in this way.
