A process for including a fine particulate filler into tissue paper using an anionic polyelectrolyte

Abstract

(57) the method of making particulate non-cell rose granular 填料 by summary book invention containing in a crepe tissue paper, a) The stage of contacting the water dispersal system of non-cell rose granular 填料 (34) to the water dispersal system of anion polymer electrolyte polymer (35), b) Mix the water dispersal system of 填料 (38) in contact with polymer with a paper-making fiber, The stage which forms water paper-making completion 紙料 (41) containing polymer contact 填料 and a paper-making fiber, c) The stage of contacting the above-mentioned water paper-making completion 紙料 (41) to a cation yield improver (46), d) The stage which forms a paper embryo web (88) from the above-mentioned water paper-making completion 紙料 (45) on porous paper-making tools (85), e) The stage which dries from the above-mentioned embryo web (88), and forms a half-dry paper-making web, f) The stage which pastes up the above-mentioned half dry paper-making web on a Yankee drier (108), and dries the above-mentioned web to a dry state substantially, g) From the above-mentioned Yankee drier, carry out Clay Pingu of the web substantially dry with the flexible Clay Pingu braid (111), and include the stage which forms a crepe tissue paper. Prepare at least one additional paper-making completion 紙料 (31, 33), and paper-making completion 紙料 (31, 33; 45) of both of above is sent on porous paper-making tools (85), An embryo and a multilayer paper web (88) are formed from the above-mentioned 填料 content water paper-making completion 紙料 and additional paper-making completion 紙料, In this case, by generating the multilayer paper web which at least one layer (88b, 88c) consists of the above-mentioned 填料 content water paper-making completion 紙料, and consists of the above-mentioned additional paper-making completion 紙料 of the above at least one layer (88a) again, A multilayer crepe tissue paper (70) can be formed. By this method, the strong soft low dusting nature tissue paper web which can be used for manufacture of the health products of absorbency with soft toilet tissue, face tissue, absorbency towel, etc. Can be obtained.
