To increase the filler content in paper without sacrificing paper properties, clay-starch composites, made from a simple precipitation method, were used in papermaking. Compared to untreated clay, the clay-starch composite filled paper improved paper tensile up to 100~200%. The significant improvements in the paper strengths are attributed to the formation of a fiber-starch-filler sandwich structure, which avoids direct contact between filler and fiber. The tensile strength (expressed as breaking length) was modeled by using a modified Page equation suggested by Beazley, Dennison, and Taylor (BDT). The experimental results agreed very well with the modeling results. |
