Smooth cotton thread (5)

I believe the answer is:
lisle
'smooth cotton thread' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for lisle that I've seen before include "Fine cotton thread used in stockings" , "Fine smooth cotton thread for stockings" , "Type of cotton yarn" , "Pedestrianised city" , "Strong cotton fabric" .)
