Abstract: The present invention relates to a process of producing a cellulosic fibre web comprising a) providing a cellulosic suspension and adding a debonder system to the suspension b) dewatering the cellulosic suspension and forming a cellulosic fibre web c) applying colloidal silica particles in an amount from about 0.01 to about 5 kg/t cellulosic fibres to said cellulosic fibre web, wherein no polymer is added to the formed cellulosic fibre web. The invention also relates to a cellulosic fibre web obtainable by the method.

Abstract: The present invention relates to a method for the production of paper from a suspension containing cellulosic fibers comprising adding to the suspension and/or to a formed paper prepared from the cellulosic suspension i) a nitrogen-containing organic compound separately and/or in conjunction with, ii) an aqueous dispersion of an acid anhydride and iii) at least one shading dye, draining the suspension on a wire to form a paper.

Abstract: The invention relates to an aqueous dispersion of cellulose-reactive sizing agent containing an acid anhydride, an anionic polyelectrolyte and a nitrogen-containing organic compound which is an amine or quaternary ammonium thereof having a molecular weight less than 180 and/or having one or more hydroxyl groups. The invention further relates to a process for the production of paper which comprises adding the aqueous dispersion of cellulose-reactive sizing agent to an aqueous cellulosic suspension.

Abstract: The invention relates to a composition used for enhancing softness in paper products. The composition comprises (i) an oil, fat or wax (i) at least one non-ionic surfactant (iii) at least one anionic compound selected from anionic microparticles and anionic surfactants (iv) at least one polymer which is cationic, non-ionic or amphoteric wherein the non-ionic surfactant is added in an amount of from about 60 to about 1000 parts by weight per 100 parts by weight of the polymer. The invention also relates to a process for production of paper comprising adding said composition to a cellulosic suspension or to a wet or dry paper web.

Abstract: The invention relates to a papermaking process in which the static potential of the fibers/paper product can be controlled and reduced while enhancing the softness of the produced paper product. The papermaking process comprises adding to a suspension of cellulosic fibers: (i) a smectite clay (ii) at least one anionic compound selected from anionic microparticles and anionic surfactants (iii) at least one polymer which is cationic, non-ionic or amphoteric (iv) at least one non-ionic surfactant; and/or an oil, wax or fat.

Abstract: The present invention relates to a process for the production of paper which comprises: (a) providing an aqueous cellulosic suspension; (b) separately adding to the suspension: (i) a nitrogen-containing organic compound having a molecular weight less than 1,000; and (ii) a cellulose-reactive sizing agent; and (c) dewatering the obtained suspension to form paper. The invention further relates to a process in which a nitrogen-containing organic compound having a molecular weight less than 1,000 is mixed with an aqueous dispersion of a cellulose-reactive sizing agent to form a pre-mix and which premix is added to the suspension.
