    摘要： A method of operating a papermaking process containing a press section with at least one press nip is disclosed. The method comprises simultaneously performing the following steps: (a) providing a press media for said papermaking process that has a MFP size that is less than the MFP size of a press media that was originally supplied to said papermaking process; (b) adding an effective amount of one or more press sheet dewatering additives to said papermaking process prior to the last press nip of said papermaking process; (c) providing a sheet moisture ratio of a paper sheet entering a press nip of said press section to between about 2 to about 9; and (d) applying an optimum rate of pressure development at one or more press nips of said papermaking process, wherein said steps a, b, c, and d either: result in the production of a more uniform paper sheet without the reduction in paper solids exiting the press section that would be expected from performing a, c, and d, alone or in combination with one another; or result in the production of a more uniform paper sheet with an increase in solids content of said paper sheet exiting the press section

    摘要： Novel sizing mixtures to achieve improved sizing along with other benefits is disclosed and claimed. The invention is a composition comprising a sizing mixture having a stabilizing amount of one or more aldehyde-functionalized polymers and a sizing amount of a sizing composition. The invention is also a method of improving paper and paperboard production and enhancing sizing through adding an effective amount of the disclosed sizing mixture to the paper machine and a method of producing a medium having cellulosic fibers, wherein the method includes adding the disclosed sizing mixture to the medium at any point in a papermaking process.
