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