Navel-gazer's discovery, maybe (4)

I believe the answer is:

lint

(Other definitions for lint that I've seen before include "Fabric for dressings" , "Soft material for dressing wounds" , "Wound dressing" , "Napped cloth used to dress wounds" , "Absorbent material for dressing wounds" .)

I've seen this clue in The New York Times.
