Fabric bringing US city half of capital (5)
I believe the answer is:
nylon
'fabric' is the definition.
(nylon is a kind of fabric)
'us city half of capital' is the wordplay.
'us city' becomes 'ny' (short for New York).
'half of capital' becomes 'lon' (I've seen this in other clues).
'ny'+'lon'='NYLON'
'bringing' is the link.
(Other definitions for nylon that I've seen before include "Plastic used for stockings" , "Man-made fibre" , "Stocking; polymer" , "Man-made material" , "Tough synthetic material" .)
