Royals use this material to trouble fool surrounded by silence (9)

I believe the answer is:
sailcloth
'royals use this material' is the definition.
'sailcloth' can be an answer for 'material' (sailcloth is a kind of material). I am unsure of the rest of the definition.
'trouble fool surrounded by silence' is the wordplay.
'trouble' becomes 'ail' (synonyms).
'fool' becomes 'clot' (I've seen this before).
'surrounded by' means one lot of letters goes inside another.
'silence' becomes 'sh' ('sh' is said to tell someone to be silent).
'ail'+'clot'='ailclot'
'ailclot' going inside 'sh' is 'SAILCLOTH'.
'to' acts as a link.
Can you help me to learn more?
(Other definitions for sailcloth that I've seen before include "fabric" , "I call host (anag) - canvas" .)
