(57) [Abstract] [PROBLEMS] To develop a papermaking method capable of improving the yield of cellulose fibers and fillers and improving drainage in a papermaking process. SOLUTION: In a papermaking process of papermaking, a dispersion polymerization method of a stock material in a salt aqueous solution (that is, a polymer electrolyte soluble in the salt aqueous solution in a salt aqueous solution in which a monomer is dissolved but a produced polymer is not dissolved) In the coexistence of a dispersant consisting of, an amphoteric water-soluble polymer produced by polymerization is carried out with stirring to obtain a dispersion liquid of fine polymer particles, and then mixed, and then anionic colloidal silica and / or The problem can be solved by a papermaking method in which bentonite is added and mixed. |
