Canvas...I never thought of that but it makes sense. Now that you mention canvas I can recall lots of similar uses for canvas on military vehicles to provide some protection for or from moving parts exposed to the elements.
I just had my "as seen on TV" expanding garden hose blow out on me. It is a soft rubber hose protected by a loose woven nylon cover. Now that the hose is ruined I may salvage the nylon cover to use on my chains. I'm happy to send you some if you want to try it out on yours.
