The invention relates to nonwoven filter fabrics comprising cellulosic fibers and methods of manufacturing such fabrics. The nonwoven filter fabric consists of a compressed fibrous array comprising at least in part cellulosic fibers which contain as a finish a liquid aliphatic polyhydroxy alcohol which is free or substantially free from fatty acids. The alcohol provides the array with sufficient strength to be usable as a filter yet allows waste pieces of fabric to be disintegrated to recycle the fibres. |
