THE EFFECT OF MULTI-COMPONENT RETENTION SYSTEMS ON THE ...
Two-component retention systems consisting of cationic fixer, cationic starch and cationic or anionic polymer, have the following influence as compared to one-component retention systems: they neutralize anionic charge in the system and fix colloid particles, dyes and wet strength reagents. At the same time, load water is decreased (COD, BOD5).

Cationic polyacrylamide was selected as a retention aid along with the CNF addition to retain it on fiber surfaces during the papermaking process. The results showed that though the effects of CNF were similar to those of BSWK in the most of properties but there were some important differences which can industrially be noticeable.
