I'm a little stuck... Click here to teach me more about this clue!

'material in youngster's' is the definition.
'rayon' can be an answer for 'material' (type of fabric). I am unsure of the 'in youngster's' bit.

'drawer conservative ignored' is the wordplay.
'drawer' becomes 'crayon' (something which draws).
'conservative' becomes 'C' (UK political abbreviation).
'ignored' is a deletion indicator.
'crayon' with 'c' removed is 'RAYON'.

Can you help me to learn more?

(Other definitions for rayon that I've seen before include "Man-made fibre" , "Viscose fibre" , "Viscose fabric" , "Artificial fibre" , "Synthetic fibre" .)
