Abstract
The use of microparticulate retention aids was investigated in three different papermaking systems: the deposition of PCC on kraft fibers, flocculation of TMP fibers and the deposition of fines on TMP fibers. It is shown that montmorillonite significantly increases both particle deposition and fiber flocculation. This is attributed to a higher bond strength in the presence of a microparticle. The role of the microparticles is to provide links between adsorbed polymer layers. The bond strengthening is explained by the asymmetric nature of an adsorbed polymer layer.
