摘要

Chips from both mixed southern hardwoods and reed (Arundo donax) were pulped using a typical kraft process. Bleaching was carried out with a TCF sequence, and the bleached pulps were beaten in a PFI mill and tested for optical and physical properties. The air-dried reed chips required slightly more alkali than did the wet wood chips to reach a bleachable-grade Kappa number. Total and screened yields were moderately lower for the reed cooks. The brightness of the unbleached reed pulp was significantly higher than for the wood pulp. Bleachability for both pulps was similar. The bleached reed pulp was much easier to refine. Optical and physical properties for both beaten pulps were similar.
