Touched material (4)
I believe the answer is:
felt
This clue is a double definition.
'touched' is the first definition.
(feeling is a kind of touching)
'material' is the second definition.
(I know that felt is a type of material)
(Other definitions for felt that I've seen before include "Ran one's hand over" , "Experienced, say, emotion" , "hat-maker" , "investigated in touching way" , "Fabric - perceived by touch" .)
