Material dug up put back (5)
I believe the answer is:
denim
'material' is the definition.
(type of fabric)
'dug up put back' is the wordplay.
'dug up' becomes 'mined' (I've seen this in another clue).
'put back' shows that the letters should be reversed in order.
'mined' written backwards gives 'DENIM'.
(Other definitions for denim that I've seen before include "Coloured cotton twill" , "Coarse durable twill-weave cotton fabric" , "Cloth for jeans, etc" , "dark blue material" , "Material for casual trousers or jackets" .)
