Abstract: Cellulose is a green and sustainable feedstock that can be used for manufacturing many bio-based products. Dissolving pulps, the main source of high-purity cellulose, have been extensively used in the production of cellulose-based products. The reactivity of dissolving pulp is a critical property because a high reactivity can decrease the production cost and environmental impact of application processes, in particular for the viscose rayon production. This review discusses the factors which affect the reactivity of dissolving pulp, including raw materials, manufacturing processes, drying and oxidation. Various methods to increase the reactivity of dissolving pulp are discussed, and they include mechanical treatment, enzymatic treatment, caustic extraction, ionic liquid extraction, acid treatment, ozone treatment, thermal degradation, and their combinations. Their advantages and disadvantages are compared and analyzed. Finally, the practical implications of effective methods to improve the reactivity and the future of dissolving pulp are discussed.Graphical Abstract:
