Lumen restoration of mineral filler to cellulose fiber for paper manufacture

摘要

(57) Abstract The grain of the mineral filler is introduced inside lumen of the wood pulp fiber, the manner containment is disclosed. The filler high - is mixed with consistency pulp slurry, portion of all filler is made to distribute inside lumen. It treats with the coagulant which shows high chemical compatibility the fiber restoration, the fiber compared to vis-a-vis the filler. The filler grain which coheres conservation, in order not to diffuse outside lumen. At equal filler restoration level, as for the paper which was formed with the lumen restoration modulo of this invention, the mechanical strength which is superior than the paper which is produced with usual modulo is shown.
