| Abstract:The bacterial cellulose was separated using fluffer and PFI mill respectively and separately added into the softwood pulp suspension to prepare handsheets. The strength properties of the handsheets were compared. The result showed that the strength properties are the best when the amount of the bacterial cellulose separated by fluffer is about 3%, the tensile index, tear index, burst index, folding endurance are improved by 40.7%, 40.9%, 38.3%, 23.2% respectively. The strength properties improve obviously when the bacterial cellulose is separated by PFI mill under 12000 revolutions the tensile index, tear index, burst index, folding endurance increase by 77.6%, 20.4%, 38.2%, 25.3% respectively. Comparing the two separating methods, the latter is better than the former. |
