Fellow providing towelling material (5)
I believe the answer is:
terry
I believe this is a double definition.
'fellow' is the first definition.
(Terry is a man's name)
'towelling material' is the second definition.
(terry is a type of fabric used to make towels)
'providing' is the link.
(Other definitions for terry that I've seen before include "(Rhyming) man's name" , "Famous actress" , "Towelling material" , "A man" , "Terence (dim.)" .)
