Two males producing cloth (7)
I believe the answer is:
buckram
'cloth' is the definition.
(buckram is a kind of cloth)
'two males' is the wordplay.
'two males' means two replacements for 'male'.
'male' becomes 'buck' (a male deer).
'male' becomes 'ram' (male sheep).
'buck'+'ram'='BUCKRAM'
'producing' is the link.
(Other definitions for buckram that I've seen before include "stiff stuff!" , "Coarse stiffened cloth" , "Coarse stuff" , "Cloth stiffened with size" , "Coarse material" .)
