Abstract

The purpose of this study was to investigate effects of lignocellulosic fillers made of wood powder and inorganic fillers, such as GCC and PCC, on physical properties of papers. Mechanical treatment and chemical treatment were carried out subsequently for generating lignocellulosic fillers, and then inorganic filler and wood powder were mixed together, and then mechanically treated for making lignocellulosic fillers covered with inorganic fillers. Consequently the particle size of lignocellulosic fillers was higher than that of inorganic fillers, which led to lumen loading and simultaneously surface coverage of fine inorganic fillers. Lignocellulosic fillers contributed to the increase of both bulk and opacity of handsheets dramatically, but some of properties including tensile strength, brightness and roughness decreased compared to inorganic fillers.
