A differential density absorbent towel paper product comprising at least one absorbent towel paper web is disclosed. The absorbent towel paper web has: (a) from about 20% to about 90% by weight of the dry fiber basis of the absorbent towel paper web of a refined soft wood pulp fiber mixture, (b) pulp fibers selected from the group consisting of hard wood fibers, non-wood fibers, recycled fibers, synthetic polymer fibers, bleached eucalyptus kraft fibers, and combinations thereof and, (c) not more than about 10% by weight moisture. The refined soft wood pulp fiber mixture has: i) from about 18.5% to about 88.5% by weight of soft wood pulp fiber; ii) from about 0.25% to about 5.0% by of cationic strengthening polymer; and, iii) from about 0.05% to about 20% by weight of cellulose nano-filaments.

The present disclosure generally relates to glyoxalated polyacrylamide (GPAM) compositions, methods of preparation and methods of use thereof, particularly in the paper industry. Moreover, the present disclosure generally pertains to cationic GPAM compositions, methods of preparation and methods of use thereof in papermaking applications and in products such as paper-based products, wherein the cationic GPAM compositions may provide increased wet and/or dry strength to the paper-based products, and wherein such cationic GPAM compositions optionally require a reduced volume of an aqueous carrier for storage or transport compared to a volume of an aqueous carrier needed for conventional GPAMs used in papermaking.
