The dryer balls accelerate this "separation" and allows warm air to flow between garments faster and easier. Additionally, wool dryer balls help to soften fabrics when used in the dryer. The balls continually agitate against the fibers in clothes and linens. So, after a (shorter) drying cycle, your clothes would also be soft to the touch.
