The objective of this current work was to investigate the rate determining factor for wet-strength polymer retention in an aqueous fibrous suspension using polyamide-epichlorohydrin (PAE). The fundamental frame of the classical transition state theory was introduced to the polymer adsorption concept depicted as a forward elementary reaction of reversible molecular adsorption. The magnitudes of the equilibrium and kinetic constants determined clearly proved that the PAE polymer retention on fiber is mainly governed by molecular diffusion through the solution. In the second regime of this study, the rate of the diffusion-controlled retention process was determined using a theoretical hydrodynamic diffusion model. The model agreed well with the empirical results; it introduced a new concept of the diffusion limiting angle present on the adsorption site of the fiber surface.

Keywords:PAE;adsorption;fiber;rate limiting factor;diffusion limiting angle
