The research of adding bacterial cellulose to improve the strength of long-fiber paper

Abstract

BC (Bacterial Cellulose) is fermented by the bacteria and other microbes from wood vinegar. This paper studies using the well dispersed bacterial cellulose fibers which is modified by polypropylene with plant fibers to make paper .According to the changes of the physical properties indicators of the paper, we get the better ratio of furnish proportion and pulp freeness. Experiments show that when the bacteria fiber was 3%, while the freeness of 40 ° SR, the physical properties of the sheet reaches a maximum. Tensile index was 82.4N • m / g increase by 12.6% and a tear index of 11.4mN • m2 / g increase by 10.1%, burst index of 6.05kPa • m2 / g improved 7.82%. Introduction
