Abstract

This study examined how the percentage of mineral fillers and their various types, when added to the base paper, affects the mechanical characteristics of latex impregnated paper.

A series of model handsheets were produced and subjected to physical property tests. The basis weight of these handsheets was held constant, as various types and percentages of filler were added. This base paper was then impregnated with a known acrylic emulsion. All variables with the impregnation process were held constant during the impregnation process. Physical properties were tested on the handsheets before and after impregnation. All physical tests on the handsheet samples were carried out in accordance with TAPPI procedures.

Evaluation was completed to determine the effect that different filler types have on the physical properties of impregnated paper, along with the relationship of mineral filled paper grades before and after impregnation. The results indicated moderate increases in smoothness, decreases in air permeability and reductions of all strength properties with the increased addition of mineral fillers to the base sheet of the latex impregnated paper.
