Bibs that somehow nourish? (7)

'bibs' is the definition.
The definition and answer can be both man-made objects as well as being plural nouns.
Perhaps you can see a link between them that I don't see?

'somehow nourish?' is the wordplay.
I cannot quite understand how this works, but
'nourish?' could be 'feed' (nourishing is a kind of feeding) and 'feed' is found in the answer.
The remaining letters 'ers' is a valid word which might be clued in a way I don't understand.
This may be the basis of the clue (or it may be nonsense).

'that' acts as a link.

Can you help me to learn more?
