Abstract

The goal of this work was to clarify the effects of sequential addition of commercial cationic and anionic polymers on wet and dry web tensile and relaxation characteristics. Studies were carried out at laboratory and pilot scales. Both wet and dry paper strength was observed to increase using sequential polymer addition mode (i.e. cationic starch to pulp suspension and A-PAM by spraying onto wet web). Wet web residual tension was not observed to change compared to reference and thus, presumably different polymers strengthened fiber-fiber contacts but had small effect on readiness of fiber network to carry load. Based on the studies sequential addition of cationic (to pulp suspension) and anionic (by spraying onto wet web) polymer appears to be interesting way to enhance the dry and wet web tensile strength.
