I don't think it will work as well. If you have a specific material you want to try, you could certainly test it to be sure. But I have found poly fibers I tested to be pretty ineffective. Same with organics like cotton. Both seem to act more like a solid mass, less like a damper.
I also think in terms of health, fiberglass insulation is often maligned unreasonably. This is probably because it looks similar to asbestos, which is harmful. But fiberglass is not, it is completely benign, and is probably the safest stuff you can use.
I mean, I know it is irritating to install it, because it makes you itch. But it is only irritating when it is disturbed, when your skin brushes against it. Once it is installed, it settles does and does not give off fibers into the environment. Sound energy isn't enough to break the fibers loose, so they do not enter the air.
