Only distributed new fabric (5)
I believe the answer is:
nylon
'fabric' is the definition.
(nylon is a kind of fabric)
'only distributed new' is the wordplay.
'distributed' is an anagram indicator.
'new' becomes 'n' (common abbreviation eg NT for New Testament).
'only' is an anagram of 'nylo'.
'nylo'+'n'='NYLON'
(Other definitions for nylon that I've seen before include "Man-made fabric" , "Fibrous material" , "Strong, resilient, synthetic fibre" , "Artificial fibre" , "Stocking; polymer" .)
