Pants fabric (5)
I believe the answer is:
chino
'pants fabric' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for chino that I've seen before include "Durable cotton fabric" , "Cotton cloth used in trousers" , "Coarse cotton khaki-coloured fabric" , "Cotton textile material" , "Type of fabric" .)
