In addition to the pre-hydrolysis kraft process, the dissolving pulp derived from woody materials is also commercially produced by the sulfite process (Sixta et al., 2013). Compared with the sulfite-based dissolving pulp, the kraft-based dissolving pulp has higher a-cellulose content but lower reactivity; on the other hand,the reactivity of hardwood kraft-based dissolving pulp is usuallylower than that of softwood kraft-based dissolving pulp (Ibarra et al., 2010; Strunk et al., 2011). In this sense, it would be desirable to enhance the accessibility and reactivity of hardwood kraft-based dissolving pulp.
