Dryer debris (4)
I believe the answer is:
lint
'dryer debris' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for lint that I've seen before include "Soft cloth for dressing wounds" , "Absorbent material for dressing wounds" , "Napped cloth used to dress wounds" , "Soft material for dressing wounds" , "Fabric for dressings" .)
