摘要： A wet-laid absorbent sheet includes a mixture of pulp-derived papermaking fibers and synthetic polymer fibers, a strength agent selected from carboxymethylcellulose and anionic starch as well as an epihalohydrin/amine functional wet strength resin. Also included is an anionic olefin copolymer resin effective to increase the wet/dry tensile ratio of the sheet.

摘要： The invention relates to a process for making paper or paper board comprising forming a cellulosic suspension, flocculating the suspension, draining the suspension on a device to form a sheet and then drying the sheet, wherein the suspension is flocculated using a formation improving 3-component flocculation system comprising a) a linear cationic or ampoteric co-polymer of: i) acrylamide, and ii) a substance with formula (I) with a halide as counter-ion; b) at least one water soluble component chosen from the group of anionic polyacrylamide, non-ionic polyacrylamide and polyethyleneoxide; and c) inorganic microparticles, whereby the flocculation system does not contain a wafer-dispersible or branched anionic organic polymer. The invention also relates to use of the flocculation/retention system in the manufacture of paper or paper board, and to paper and paper board thus produced.

摘要： The invention relates to a cellulosic product containing thermoplastic microspheres and a charged aromatic acrylamide-based polymer. The invention further relates to a process for a process for producing a cellulosic product which comprises providing an aqueous suspension containing cellulosic fibres; adding to the suspension thermoplastic microspheres and a charged aromatic acrylamide-based polymer; and dewatering the obtained suspension. The invention also relates to the use of the cellulosic product as a liquid packaging board.

摘要： A process of making filled paper comprising the steps of providing a thick stock cellulosic suspension that contains mechanical pulp and filler, diluting the thick stock suspension to form a thin stock suspension, in which the filler is present in the thin stock suspension in an amount of at least 10% by weight based on dry weight of thin stock suspension, flocculating the thick stock suspension and/or the thin stock using a polymeric retention/drainage system, draining the thin stock suspension on a screen to form a sheet and then drying the sheet, in which the polymeric retention/drainage system comprises, i) a water-soluble branched anionic polymer and ii)a water-soluble cationic or amphoteric polymer. The process is particularly suitable for making filled mechanical grade paper, such as SC grade paper. The process enables the separation of retention and drainage parameters, especially useful for fast draining paper machines, such as Gapformers.
