Angora fabric (6)
I believe the answer is:
mohair
'angora fabric' is the definition.
(I've seen this before)
This is the entire clue.
(Other definitions for mohair that I've seen before include "Fine silky wool of the angora goat" , "Fabric made from the coat of an Angora goat" , "Angora fleece" , "Fine hair fabric" , "Fabric made from fine silky wool of goat" .)
