Silky wool (6)
I believe the answer is:
angora
'silky wool' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for angora that I've seen before include "Yarn or fabric from hair of goats or rabbits" , "Fine yarn from hair of goats" , "Breed of rabbit or cat, the former name for the Turkish capital" , "Breed of goat with silky hair" , "Breed of goat, cat or rabbit" .)
