Caustic- and acid-resistant nonwoven articles useful for surface conditioning of sheeting, especially metal sheeting, and a method for the manufacture of such articles are described. 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.

Surface conditioning articles and process for making same

The invention relates to repulpable securing devices for securing repulpable articles. The securing devices are preferably in the form of straps or tapes made from extruded sheets of polyvinylalcohol or rope from extruded fibers of polyvinylalcohol. The securing devices are wrapped around pulpable articles for example, bales of pulp sheets, to hold them securely bound during transit or storage. They may also be used in machine thread-up or turn-up operations or as a handle for repulpable articles. The securing devices have the combination of properties of high tensile strength and repulpability at cold and hot water repulp temperatures. The securing devices can be repulped along with repulpable bales. These devices replace conventional wire or plastic strap which must be separately removed and disposed of, for example, at landfill sites.
