The adsorption kinetics of polyamide-epichlorohydrin wet-strength resin in aqueous papermaking fibrous suspension was investigated using colloid titration and adsorption modeling. The time-dependent behavior of PAE adsorption obeyed a mono-molecular layer adsorption as characterized in Langmuir-type expression. The initial increase in PAE adsorption was fast for a few minutes, but it slowed down at longer times as the fiber surface become saturated. The primary apparent rate constants and the maximum adsorption PAE were determined using slow near-equlibrium adsorption kinetics. The secondary apparent rate constants later being required in PAE adsorption simulations were then determined with the model fitting on the initial dynamic adsorption kinetics. The prediction model provided the real-time PAE adsorption behavior on fibers in aqueous solution and showed a good agreement with the experimental data.
