The articles comprise a plurality of compacted, stacked nonwoven web elements, the web elements each comprising entangled fibers bonded together at points of mutual contact by an adhesive binder, the binder comprising a terpolymer of acrylonitrile butadiene styrene. The nonwoven articles can be configured into any of a variety of convenient and useful shapes, such as roll shapes and slab or bar shapes.
