A novel approach for determining the reactivity of dissolving pulp based on the COD method
ABSTRACT: A novel approach for determining the reactivity of dissolving pulp according to the chemical oxygen demand (COD) of water has been discussed. First, a sample of dissolving pulp was subjected to mercerization and xanthation in order to obtain dissolved cellulose fractions. Next, the fractions were digested with a testing solution as applied in COD procedures. Finally, the resulting liquid was rapidly tested by ultraviolet-visible spectrophotometry (UV-Vis). By quantifying the absorbance of Cr3+ at a wavelength of 600 nm, the reactivity of dissolving pulp was indirectly calculated. The results measured by this novel COD method correlated well with the most accepted Fock test results with less than 10% relative difference. Meanwhile, this newly developed COD method required less time-consuming procedures as compared to the Fock test.

Nanocellulose in Japan: An industrial perspective, TAPPI Journal April 2019
ABSTRACT: With the maturing of Japan’s economy, domestic demand for paper and paperboard is more likely to level off in the long term. Japanese paper companies are accelerating overseas production, especially in the emerging Asian markets, while strengthening competitiveness of domestic mills and developing new products. In Japan, we have always focused on emerging technologies and driving innovation in the pulp and paper industry. As a business definition, innovation does not equal innovative technology. Innovative technology can become innovation only when it is commercialized and used in industry.
