Abstract:
A tissue paper product is provided having at least one ultra-low density ply having a highly porous, open-celled structure and that comprises cellulosic fibers, a water insoluble binder and a foaming surfactant. The cellulosic fiber comprises greater than 50% by weight of the ply and are bonded to one another by hydrogen bonding. Further, the ply has a density less than about 0.04 g/cc and yet still provides low lint and high strength properties with the use of minimal binder. The ultra-low density ply may comprise or be included in sheets forming a stack of dispensable wipers or may be employed as or part of an absorbent core or liquid distribution layer of a personal care absorbent personal care product such as a diaper or feminine pad.
