Abstract

The aim of this study was to use PRECIPITATED CALCIUM CARBONATE modified by cationic starch as the filler in writing and printing paper and compare the STRENGTH PROPERTIES of the resulting paper with similar paper using conventional filler (unmodified). One of the limitations of adding fillers to paper is the reduction of the mechanical strength of paper because of reduction in bonding between fibers. In this study with purpose of maintaining the strength of paper, the surface charge of PRECIPITATED CALCIUM CARBONATE was modified and the resulting filler was used. The cationizing condition of cationic PRECIPITATED CALCIUM CARBONATE was selected as; 90oc temperature, 3 hours and 55% water content of cooking process. Loading amount of starch was 9, 12 and 15 percent (w/w) based on PRECIPITATED CALCIUM CARBONATE. Paper was made at three level; 10, 16, 30 percent of filler in paper sheets and compared with conventional fillers. Results indicated that papers containing modified filler retained more filler than those with unmodified filler, at either 20% and 30% filler dosages. Papers contained modified filler showed higher mechanical strength index as compared with papers containing conventional fillers.
