Parachute material (5)
I believe the answer is:
nylon
'parachute material' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for nylon that I've seen before include "The first synthetic fibre" , "Unaccompanied part song" , "Man-made fibre" , "Yarn for stockings" , "Fibrous material" .)
