Nip back, love, to get the material (6)
I believe the answer is:
poplin
'the material' is the definition.
(poplin is a kind of material)
'nip back love to get' is the wordplay.
'back' says the letters should be written backwards.
'love' becomes 'opl' (I can't justify this - if you can you should give a lot more credence to this answer).
'to get' is an insertion indicator.
'nip' back-to-front is 'pin'.
'pin' placed around 'opl' is 'POPLIN'.
Can you help me to learn more?
(Other definitions for poplin that I've seen before include "Corded cotton fabric" , "Type of fabric" , "Lightweight corded cotton" , "Material" , "stuff!" .)
