    Abstract: A high-durability paper and method of manufacture thereof. The paper may be intended for manufacturing bank notes, offering good resistance to circulation, especially good resistance to pulverulent soiling in dry medium, to friction in wet medium and to soiling in wet medium, which is moreover appropriately capable of satisfying all the manufacturing constraints, especially the printing constraints. The high-durability paper includes a fibrous substrate, and a protective coat completely covering at least one face of the fibrous substrate, where the protect coat includes at least one base layer on the substrate side and a polyurethane-based outer printability layer that covers the base layer.

    Abstract: Disclosed is a composition for softening a wet laid cellulosic structure. A particularly preferred structure is an absorbent tissue. Further disclosed are tissue structures softened using the composition. The composition includes an effective amount of a softening active ingredient; a vehicle in which the softening active ingredient is dispersed; an electrolyte dissolved in the vehicle; and a bilayer disrupter. The electrolyte and the bilayer disrupter cooperate to cause the viscosity of the composition to be less than the viscosity of a dispersion of the softening active ingredient in the vehicle alone. Preferably, the softening active ingredient is a quaternary ammonium compound with the formula: (R1)4-m—N+—[(CH2)n—Y—R3]mX− the vehicle is water, the electrolyte is calcium chloride, and the bilayer disrupter is a nonionic surfactant. Also disclosed is a method of using the compound by adding it at a use concentration to the wet end of a papermaking process.

    Abstract: A process for improving the freeness of paper pulp, which comprises the steps of adding to the pulp at least 0.05%, based on the dry weight of the pulp, of a cellulolytic enzyme, allowing the pulp to contact the cellulolytic enzyme for from about 40 minutes to about 60 minutes at a temperature of at least 40.degree. C., adding at least 0.011%, based on the dry weight of the pulp, of a water soluble cationic polymer, adding at least 0.007%, based on the dry weight of the pulp, of a water soluble anionic or nonionic polymer and forming the thus treated pulp into paper.

    Abstract: Systems and methods for attaching particulate additives to a population of cellulose fibers dispersed in an aqueous solution are described. The cellulose fibers are treated with an activator that forms complexes with them. The particulate additive is attached to a tether that is capable of interacting with the activator, thereby forming a tether-bearing particulate additive. The tether-bearing particulate additive can be added to the activated suspension of cellulose fibers. The resulting interaction between the tether and the activator forms durable complexes that attach the particulate additive to the cellulose fibers. Using these systems and methods, useful additives like starches can be attached to cellulose fibers, imparting advantageous properties such as increased strength to paper products formed thereby. These systems and methods are particularly useful for papermaking involving virgin pulp fibers, recycled fibers, or any combination thereof.

    Abstract: A storage stable, flowable aqueous dispersion of an amphoteric water-soluble polymer with good handling as well as a method of manufacturing the same are provided. Such an aqueous dispersion can be effectively used for flocculating and/or dehydrating sludge, or for separating and treating oil-containing industrial waste water, as a drainage aid, a retention aid, or recovering substances from white water in the papermaking process. The aqueous dispersion of an amphoteric water-soluble polymer is obtained by polymerizing a mixture of monomers comprising a specific cationic monomer and an anionic monomer as essential components wish stirring in an aqueous salt solution incapable of dissolving the produced polymer and in the presence of a polymer electrolyte dispersant soluble in said aqueous salt solution. Such an aqueous dispersion is highly effective when the concentration of the produced amphoteric water soluble polymer in the aqueous dispersion, the concentration of the salt, the concentration of the dispersant, the viscosity of the aqueous dispersion, and the average diameter of the particles of the amphoteric water-soluble polymer in the aqueous dispersion are found within specific ranges.
