Glove thread (5)
I believe the answer is:
lisle
'glove thread' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for lisle that I've seen before include "Cotton stocking thread" , "Strong twisted cotton thread for the strange Ellis" , "Pedestrianised city" , "Type of cotton yarn" , "(Fabric woven with) a fine cotton thread" .)
