Summary:A process for the production of paper by forming and dewatering a suspension of cellulose containing fibers and optional fillers on a wire in the presence of a cationic silica based sol and a cationic polymeric retention agent. The cationic polymeric retention agent is cationic guar gum or a cationic synthetic polymer such as cationic polyacrylamide. The combination of cationic silica sol and cationic polymeric retention agent gives improved retention of fines and fillers and eases drainage.
