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.
