Fabric in shawl is Lebanese (5)
I believe the answer is:
lisle
'fabric' is the definition.
(I've seen this before)
'in shawl is lebanese' is the wordplay.
'in' indicates a hidden word.
'LISLE' can be found hidden inside 'shawl is lebanese'.
(Other definitions for lisle that I've seen before include "(Fabric woven with) a fine cotton thread" , "Fine smooth cotton thread for stockings" , "Strong tightly twisted cotton thread" , "Strong twisted cotton thread for the strange Ellis" , "Cotton stocking thread" .)
