PURPOSE:To obtain paper outstanding in both formation and the respective yields of filler and fine structure, by incorporating a raw paper suspension with a cationic polyelectrolyte and a bacteria cellulose-opened product followed by papermaking. CONSTITUTION:A raw paper suspension is incorporated with (A) a cationic polyelectrolyte [e.g., cationic polyacrylamide, (epoxidized)polyamidepolyamine, with a molecular weight of >=100,000] and (B) a bacteria cellulose-opened product (e.g., obtained by mechanically opening cellulose, etc., produced by microorganisms) followed by papermaking, thus obtaining the objective paper. Preferably, the weight ratio A/B=0.05-10.0. |
