Retention systems and methods for papermaking |
| abstract |
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. |
