A method for manufacturing paper is disclosed. A pulp slurry is produced, a paper sheet is formed from the slurry, an aldehyde functionalized polymer or polymers in combination with at least one additional strength additive is added to the slurry before and/or after sheet formation, and a water soluble acid is added on the paper sheet.

A process for improving the dry strength of the paper by applying a dry-strength enhancing composition to pulp during a paper-making process, said dry-strength enhancing composition comprising a solution comprising an acid mixed with at least one metal ion wherein the metal ion is generally provided as a metal sulfate or a solubilized sulfate to form a mixture (I), wherein the mixture generates an exothermic reaction to form a mixture (II) and wherein the mixture is cooled to form the dry-strength enhancing composition.

A pulp fiber with an enhanced carbonyl content resulting in improved antimicrobial, anti-yellowing and absorptive properties. Methods for making the kraft pulp fiber and products made from it are also described.
