Abstract
AbstractEgyptian bagasse was pulped by the prehydrolysis‐sulphate process. The effects of depithing on certain chemical, physical and sub‐microscopic characteristics of the pulp, in particular its reactivity towards xanthation, were investigated. Depithing before and after prehydrolysis was compared. Pulps with a higher degree of chemical purity and higher degree of whiteness showed better reactivity towards xanthation. However, the most important factor affecting the reactivity was the accessibility of the cellulose hydroxyls to reactant molecules.
