“…CNFs produced from SBKP resulted in the greatest improvement in mechanical properties (folding endurance > 1200, tensile index > 30 N•m•g -1 ) of the paper. The CNFs produced from SBKP had high viscosity, lower fibre diameter and higher zeta-potential compared to CNFs produced from BHKP (Park et al, 2018).…”

“…On the other hand, 3 wt% of CNFs improved the tensile index of OCC by 60%. The optimisation of the retention system used counteracted the negative effect on the drainage rate caused by the CNFs Park et al (2018). compared the extent to which CNFs produced from softwood kraft pulp (SBKP) and bleached hardwood kraft pulp (BHKP) improved the mechanical properties of paper made from cotton lint mixed pulp.…”

Role of cellulose nanofibrils in improving the strength properties of paper: a review

The pursuit for sustainability in the papermaking industry calls for the elimination or reduction of synthetic additives and the exploration of renewable and biodegradable alternatives. Cellulose nanofibrils (CNFs), due to their inherent morphological and biochemical properties, are an excellent alternative to synthetic additives.These properties enable CNFs to improve the mechanical, functional and barrier properties of different types of paper. The nanosize diameter, micrometre length, semi-crystalline structure, high strength and modulus of CNFs has a direct influence on the mechanical properties of paper such as tensile index, burst index, Scott index, breaking length, tear index, Z-strength, E-modulus, strain at break, and tensile stiffness. This review details the role played by CNFs as an additive to improve strength properties of papers and the factors affecting the improvement in paper quality when CNFs are added as additives. The paper also includes techno-economic aspects of the process and identifies areas that need further research.

“…The laser scattering-based particle size measurement is not a perfect method for detecting the fiber dimensions because NFCs have a high aspect ratio (Gantenbein et al 2011). However, particle size data were used to indirectly indicate the size differences between NFCs (Park et al 2018). The zeta-potential for 0.01% NFC slurry was measured using a zeta-potential analyzer (Nano ZS, Malvern Panalytical, Malvern, UK).…”

A multi-layer barrier coating technology was developed using nano-fibrillated cellulose (NFC) alongside a hydrophobic, paraffin-free biowax for manufacturing an eco-friendly functional packaging paper. Anionic NFC was prepared by isolating hardwood-bleached kraft pulp (Hw-BKP) using a micro-grinder, and cationic NFC was prepared by the quaternization reaction of the anionic NFC. Thereafter, a three-layer barrier-coated paper was manufactured using cationic and anionic NFCs and biowax. The air permeability and water vapor transmission rate (WVTR) of the three-layer barrier-coated paper were measured, and its coverage and coating layer structure were observed by scanning electron microscopy (SEM). The air permeability of the three-layer barrier-coated paper was more than 15,000 s and those WVTR was 67.1 g/m2/day. Its coverage and surface were considerably uniform and smooth. Thick and effective barrier coating layers were formed as indicated by SEM images. Therefore, it was concluded that a multi-layer barrier-coated paper with considerably high barrier properties could be produced using cationic and anionic NFCs with high gas barrier properties and biowax with high moisture barrier properties. Further, the structure could be used as a functional packaging paper with high barrier properties.
