My daughter moved your material in bags? (8)
I believe the answer is:
corduroy
'material in bags?' is the definition.
'corduroy' can be an answer for 'material' (corduroy is a kind of material). I am not sure about the 'in bags?' bit.
'my daughter moved your' is the wordplay.
'my' becomes 'cor' (both are expressions of surprise).
'daughter' becomes 'd' (genealogical abbreviation).
'moved' indicates anagramming the letters.
'your' is an anagram of 'uroy'.
'cor'+'d'+'uroy'='CORDUROY'
Can you help me to learn more?
(Other definitions for corduroy that I've seen before include "Material" , "Thick ribbed cloth" , "Velvety ribbed fabric" , "Ribbed cotton fabric" , "Cut pile cotton fabric" .)
