“…This forms the basis for the use of nanocelluloses as paper strength reinforcement agents. This material is biodegradable (and renewable), with high specific strength and stiffness, high reinforcing potential, and high specific surface area (Guimond et al 2010;Osong et al 2014;Kumar et al 2016;Balea et al 2018;Viana et al 2018).…”

Recycled fibers used in the manufacturing of paper and board are associated with strength deficiencies. This study investigated the use of TEMPO-oxidized nanocellulose from oil palm empty fruit bunch (OPEFB-TEMPO) for reinforcing papers made from such fibers. Strength properties of tensile and tear were enhanced with the addition of OPEFB-TEMPO, with strong correlations, as indicated by the R2 values. The reinforcement capability was supported by the scattering coefficient-percent relationship. The only drawback of the nanocellulose addition is that it reduces pulp drainability, which can be minimized by adding drainage aids. Because only a relatively small amount is required, OPEFB-TEMPO has the potential to be used as paper strengthening agent, particularly in the production of low grammage papers.

“…Other researchers have studied refining as the main mechanical defibrillation treatment to prepare CMF or CNF without additional treatments or using a low concentration of NaOH in the fibers soak. These CMF/CNF were obtained in high consistency refiners (HCR), where the heterogeneous furnish formed by fibres and fines, water and steam is at a concentration in the range of 10-40% 41,42 ; or in low consistency refiners (LCR) at a concentration of 2-6% 26,43 . The pulp suspension acts as an incompressible fluid and is pumped through the refiner using an external pump.…”

“…Among these studies, only some of them use CMF/CNF as an additive to reinforce strength properties in paper or board. In the case of CMF/CNF prepared with HCR, Kumar et al 41 studied an increase of mechanical properties as tensile and burst indexes in three different papers from hardwood, softwood and bagasse pulps with a CNF addition up to 20%. On the contrary, drainage time is longer with the reinforcement.…”

Recycling cycles cause a decrease in mechanical paper properties due to cellulose fiber degradation. The use of cellulose micro/nanofibers (CMF/CNF) to reinforce paper strength has been well studied, although it has been found to have negative effects on drainage. However, the application of CMF/CNF as paper reinforcement is affected by the nanocellulose type. Thus in this study mechanical and chemical treatments in CNF production were compared. Old corrugated container (OCC) pulp used to produce recycled cartonboard was reinforced with 1) CMF from never-dried northern bleached softwood kraft pulp (NBSK) highly refined in a 16-inch low consistency refiner at 1200 rpm and 25 kW of net power; and 2) CNF from NBSK pulp treated by TEMPO-mediated oxidation and homogenization at 600 bars. CMF/CNF and OCC were pulped at the same time and handsheets formed with cationic starch (CS) as retention system. Mechanical, drainage and flocculation properties were evaluated and compared. Data were also compared with other sources of TEMPO CNF. Results show an improvement in mechanical properties, drainage and flocculation when OCC is reinforced with CMF obtained with LCR. Therefore, high fibrillation was not necessary to improve mechanical paper or cardboard properties.
