    摘要: Various processes and methods are disclosed for incorporating polyvinyl alcohol additives into products. In one embodiment, polyvinyl alcohol particles are dissolved in a solvent without the use of external heat to form a polyvinyl alcohol solution for incorporation into a product. In an alternative embodiment, polyvinyl alcohol particles are directly incorporated into a starch-based adhesive composition. Through the processes of the present disclosure, solid polyvinyl alcohol particles can be delivered directly to a manufacturing facility where the product that incorporates the polyvinyl alcohol additive is being made or formulated. In this manner, since the polyvinyl alcohol particles are not predissolved, the costs associated with shipping and transporting the polyvinyl alcohol product are greatly reduced.

    摘要: Corrosion-resistant adhesive compositions are provided. The compositions are useful for bonding together plies in multi-ply cellulosic fibrous structures. Multi-ply cellulosic fibrous structures incorporating the adhesives, products produced from such structures, and methods of producing the structures are also disclosed. The adhesive compositions incorporate a polyvinyl alcohol polymer and a corrosion inhibitor. The adhesive compositions may be sprayed or coated onto the cellulosic structures to bond layers of the structure to each other. The corrosion-resistant adhesive compositions are useful for preventing corrosion in the various devices used for handling and application of the adhesives such as spray equipment and applicator rolls. The cellulosic fibrous structures may be used to produce a variety of products including paper towels, toilet tissue, facial tissue, napkins, and other absorbent materials.
