摘要： Disclosed herein are systems and methods for attaching particulate additives to a population of cellulose fibers dispersed in an aqueous solution. 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.

摘要： Formulations and methods for papermaking are disclosed herein using one or more volatile debonders, where the volatile debonder forms a solution or an emulsion with water in a paper precursor, and where the volatile debonder is evaporable from the paper precursor before the paper precursor is completely dried to form a paper sheet during papermaking. Two volatile debonders having different boiling points can be used, where they are miscible in water and in each other, and where one volatile debonder has a higher molecular weight and the other volatile debonder has a lower boiling point.

摘要： Compositions and methods of producing an optically-enhanced paper-based material are disclosed. The composition can include an optical brightening agent and an additive having an aromatic portion, where the aromatic portion is associated with an optical brightening agent. The paper-based material can exhibit a higher capacity for the optical brightening agent relative to a paper-based material that lacks the additive. Techniques for increasing optical brightening agent retention in a paper-based material are also disclosed. The techniques include using an additive having an aromatic portion, where the aromatic portion associates with an optical brightening agent so that the retention of the optical brightening agent is improved.

摘要： Debonding compositions and methods are disclosed for use in fibrous compositions such as paper-based products. In some instances, debonding agents can be combined with fibers (e.g., cellulose-based fibers) to produce a material having substantial wicking properties while decreasing fiber-fiber interactions that can require substantial energy to overcome in materials processing. In some instances, the debonding agent can act to create a paper-based product exhibiting a transition temperature in which the agent has a higher affinity for the fibers at temperatures above the transition temperature, and the product exhibiting enhanced wicking properties at temperatures below the transition temperature. As an example, a debonding agents can include polymers or other material exhibiting a lower critical solution temperature. The disclosed debonding agents can provide benefits over existing debonding agent formulations such as ammonium salts.

摘要： Compositions and methods of producing paper-based materials are disclosed. The techniques can utilize an amine-containing polymer, such as chitosan, to functionalize one or more components of a mixture used to form materials such as paper-based materials. Such components can include the fibers of a pulp and/or filler particles. Techniques and compositions are also described to further improve the qualities of a paper material by utilizing a complementary polymer which can couple with the amine-containing polymer. Other compositions and methods are directed to forming paper-based materials that are expandable.
