The cellulose reactivity is a key parameter in the viscose rayon production process. To increase the reactivity of hardwood kraft-based dissolving pulp, a combined mechanical refining and enzymatic treatment was applied based on the hypothesis that a mechanical pretreatment can enhance the subsequent enzymatic treatment efficiency. Compared with the control sample, increases in the fiber specific...
The capacity of dissolving pulp to react with carbon disulfide under the defined conditions, known as the “Fock reactivity,” is an important parameter in determining the processability, end-product quality, and environmental impact in downstream rayon production. This study was aimed at improving the reactivity of kraft-based dissolving pulp by mechanical treatments, such as grinding and PFI refining,...
