The effect of CNF addition on the wet end process is analysed according to the type of pulp used for papermaking. According to the literature consulted, improvement in paper's overall properties after CNF addition depended not only on the type and amount of CNF applied, but also in the pulp's origin and treatment.

For decades, several dry-strength additives have been studied for various purposes in papermaking as promising alternatives to the mechanical treatments [,, 46, 47, 48]. Besides the extensive energy consumption of beating and refining, the treatments also make undesirable and irreversible changes in fiber structure [, 49, 50].
