  • Patent number: 7776182
    Abstract: Selected chlorohydrin and cationic compounds containing nitroxide or hydroxylamine moieties are effective in stabilizing pulp or paper, especially pulp or paper containing lignin, against yellowing and discoloration due to the adverse effects of light. These compounds are added at various points in the paper-making process, especially at the wet ends, making the need for water soluble or water dispersible materials having high affinity for pulp or paper essential. This performance is often further enhanced by the presence of one or more coadditives selected from the group consisting of the UV absorbers, the polymeric inhibitors, the nitrones, the fluorescent whitening agents and metal chelating agents. Combinations of hydroxylamines or their salts, benzotriazole or benzophenone UV absorbers and a metal chelating agent are particularly effective.

  • Publication number: 20100132902
    Abstract: The invention relates to a paper that is formed of a fibre-based source material and is applicable as printing paper. According to the invention, the surface of the paper is surface-treated by arranging on the surface sufficient density in such manner that the density of at least one surface layer of the paper is sufficiently high to yield a Gurley-Hill value of over 7000 s/100 ml as measured from the entire paper. Furthermore, the invention relates to a method for making paper.

  • Publication number: 20100132901
    Abstract: The present invention is directed to a method of efficiently maintaining or increasing brightness and whiteness of refined paper. In one aspect, the invention is directed to a method for substantially maintaining (or even increasing) brightness and/or whiteness of paper with increased pulp refining, the method including refining the pulp down to reduce the freeness at least about 100 CSF and adding a combination of an OBA and a carrier polymer to the paper surface in the size press in amounts sufficient to increase brightness and/or whiteness of the final paper. In another aspect, the invention is directed to a method of making paper from refined pulp that includes refining a cellulosic fiber suspension to reduce the freeness at least about 100 CSF and contacting the cellulosic fibers with at least one optical brightening agent (OBA) during or after the refining step prior to adding any additional wet end chemicals.

  • Publication number: 20100126684
    Abstract: The invention provides a method of producing paper with a higher proportion of mineral filler particles than is otherwise be possible without the expected loss in paper strength. The method allows for the use of the greater amount of filler particles by coating at least some of the filler particles with a material that prevents the filler materials form adhering to a strength additive. The strength additive holds the cellulose fibers together tightly and is not wasted on the filler particles. The method is particularly effective when the filler particles are a PCC-GCC blend and when the GCC particles are coated with the adherence preventing coating.
