It is called iron wool here; others call it 'steel wool'. Actually its the white very very fluffy lightweight (it is light as a feather) stuff and is usually used to line the inside of men's shirt collars (we call it 'bakram'). Fish hobbyists are using this since ages for filtration and is is good.
