The Study of Kraft Continuous Cooking of Knenaf
The paper studied the possibility of using the whole stalk kenaf as a raw material for producing high yield and good quality bleachable pulp. The stem of kenaf has two distinct parts: the bast and the core. which have markedly different chemical components and fiber morphology. In general, the length of bast fiber ranges from about 2-2.5mm, while that of the core varies from about 0.5-0.8mm, so it is important to achieve a balance of the bast fiber and the core during pulping. The study indicated that using the selected continuous cooking conditions, the properties of kenaf pulp approached to the hardwood pulp and would be easily bleached.
