Abstract: A water-dispersible sheet is described having suppressed time degradation of the tacky adhesiveness of the tacky adhesive layer, while maintaining water dispersibility. The base paper of the water-dispersible sheet has a multilayer structure, including an inner layer which is not in contact with a tacky adhesive layer and a surface layer which is in contact with the tacky adhesive layer. The layers are independently mixtures of papermaking fibers and an alkalized fibrous carboxymethyl cellulose.

Abstract: The present invention provides multi-layered tissue webs, and tissue products comprising the same, the multi-layered webs comprising wood fibers and non-wood cellulosic fibers where the non-wood cellulosic fibers are selectively deposited in one or more outer layers of the multi-layered web. Surprisingly disposing non-wood cellulosic fibers in the outer layers, even in relatively modest amounts, alters the machine and/or cross-machine direction properties of the resulting web, such that MD:CD tensile ratio may be reduced.

Abstract: Cellulosic materials modified with a surface modifier to promote compatibility with a hydrophobic material and methods for producing surface-modified cellulosic materials are provided. The methods include providing a slurry of a cellulosic material and adding a surface modifier to the slurry. The surface modifier may be added to the slurry in a soluble form and precipitated by adjusting the pH. The surface-modified cellulosic material may be solvent-dried and/or dried using conventional drying methods to enhance hydrophobicity. To solvent-dry the surface-modified cellulosic material, a solvent is added to an aqueous slurry of the surface-modified cellulosic material to form an azeotrope. The azeotrope has a boiling point that is less than the boiling point of the solvent. The slurry is distilled to remove the azeotrope from the surface-modified cellulose material. The solvent is removed from the surface-modified cellulose material.

Abstract: The present invention provides tissue webs and products that are manufactured by non-compressive dewatering and/or drying methods, such as through-air drying, where the webs and products comprise cross-linked fiber. The non-compressively dewatered tissue webs and products have improved sheet bulk and z-direction properties. For example, in one embodiment, the invention provides through-air dried tissue products having good sheet bulk and resiliency, such as a sheet bulk greater than about 15 cc/g and Compression Energy (E) greater than about 1.30 N/m. Surprisingly the foregoing products have sufficient strength to withstand use, such as a GMT greater than about 600 g/3?, but are not overly stiff, generally having a Stiffness Index less than about 12.

Abstract: A method of making a fibrous sheet. The method includes forming a nascent web from an aqueous solution of papermaking fibers, dewatering the nascent web to form a dewatered web having a consistency from about ten percent solids to about seventy percent solids, moving the dewatered web on a transfer surface, and transferring the dewatered web from the transfer surface to a molding roll at a molding zone. The molding roll includes an exterior and a patterned surface on the exterior of the molding roll. Papermaking fibers of the dewatered web are redistributed on the patterned surface in order to form a molded paper web. The method also includes transferring the molded paper web to a drying section and drying the molded paper web in the drying section to form a fibrous sheet.

Abstract: The present invention provides tissue webs and products having improved z-directional properties. The improved z-directional properties may be achieved by providing the structure with a unique three-dimensional surface topography, which increases the structure's Exponential Compression Modulus (K) and Caliper Under Load (C0). By improving both K and C0, the present inventors have also been able to provide tissue structures with relatively high Compression Energy (E), which enables the structures to be calendered at high loads without significant loss of sheet bulk or degradation of strength.

Abstract: A pulp-digester screen cleaner having a pneumatic actuator with a cylinder and a rod coaxially disposed within the cylinder. An actuator mounting plate is used to mount the actuator outside of a pulp-digester screen housing pipe. A rod seal has a body disposed on the pipe that prevents any loss of fluid or pressure, yet allows the rod to pass into the pipe. The cylinder contains all of the mechanics of the pneumatic actuator and can be easily serviced without draining the digester. The rod is disposed through a first aperture of each of a pair of scrapers. A treated edge of each of the pair of scrapers varies to match different digester screen types and patterns. The present pulp-digester screen cleaner eliminates the need for chemical cleaning or other mechanical cleaning solutions. It will also improve pulp quality, increase pulp production, and promote overall digester efficiency.
