Patent number: 11591755Abstract: 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.

Patent number: 9580869Abstract: A process is disclosed for topically applying additive compositions to planar substrates, such as tissue webs. In one embodiment, the process is designed to apply relatively high viscous compositions to base sheets at high speeds in a manner that prevents the additive composition from penetrating into the sheet. The additive composition having the relatively high viscosity can be applied to the base sheet in one embodiment using an offset gravure printing process. The applicator roll includes a pattern of raised elements. The raised elements define a surface having at least one dimension that is less than 500 microns. The raised elements are also spaced closely together in order to prevent fiber buildup on the roll during relatively fast processing speeds.Type: GrantFiled: December 30, 2010Date of Patent: February 28, 2017Assignee: Kimberly-Clark Worldwide, Inc.Inventors: Keyur Desai, Deborah J.
