PULPING WITH ADDITIVES OF TYPHA DOMINGENSIS STEMS FROM SUDAN
Keywords:
Typha Domingensis, Southern cattail stem,, Papermaking, Fiber morphology, Chemical composition, Alkaline pulping with additivesAbstract
Soda-anthraquinone (soda-AQ) alkaline sulfite-anthraquinone (AS-AQ) and ASAM (alkaline sulfite anthraquinone-methanol) cooking of southern cattail whole stem and bark from Sudan was carried out under different conditions and pulps with acceptable to good screened yields and very good mechanical properties were attained. The southern cattail whole stems gave satisfactory mechanical properties with ASAM process with good yields while the bark was best pulped with the AS-AQwith acceptable yield, but good strength properties.
