A comparative study of the effects of pulp fractionation, refining, and microfibrillated cellulose addition on tissue paper properties

Environmental and economic concerns are driving tissue paper manufacturers to improve understanding of the relationships between fibres, networks they form, forming process, final properties. This work investigated how pulp fractionation, refining, or addition microfibrillated cellulose (MFC) affect compromise absorbency strength 33 ± 2 g/m² model papers made bleached eucalyptus kraft pulp. The results showed that properties was better when fibres were refined than MFC added. capacity 2%wt MFC-paper almost 20% lower at same dry strength. calculated additional storage due water-induced deformations fibre network 40% in range bulk. By a high viscosity gel inter-fibre contacts, could limit occurrence major deformation mechanisms water imbibing paper.
