Material in name only sent out (5)
I believe the answer is:
nylon
'material' is the definition.
(I know that nylon is a type of material)
'name only sent out' is the wordplay.
'name' becomes 'n' (common abbreviation e.g. on forms).
'sent' indicates an anagram (send can mean to excite or stimulate).
'out' means one lot of letters goes inside another.
'only' is an anagram of 'ylon'.
'n' going inside 'ylon' is 'NYLON'.
'in' acts as a link.
(Other definitions for nylon that I've seen before include "where ladder can appear?" , "Cover for leg" , "Unaccompanied part song" , "Tough synthetic material" , "Synthetic cloth" .)
