چکیده | ||
Chemical and morphological characterization of different parts of banana plant (Musa paradisica) (peduncle, leaf stalk and pseudo stem) were carried out in order to assess their potentiality for chemical pulp. Each portion was tested for extractives, sodium hydroxide solubility, ash, lignin, cellulose and pentosan contents as well as their fiber length and width. These segmented parts were characterized as low amount of lignin (12.8–16.1%) and moderate amount of α- cellulose (31.6–43.3%) and relatively high amount of ash (7.6–19.1%), alkali solubility (32.4-51.4%) and water solubility. The morphological properties of the banana plant, in terms of fiber length and width were found to be a medium fiber with high slenderness ratio. Kraft process was applied for the three portions of banana plant to evaluate pulp properties. At the optimal pulping (Active alkali 22% for peduncle, 16% for leaf stalk and pseudo stem at 150 oC for 1 hour) pulp yields about 30.5–40.5% on oven dried (OD) raw material with kappa number from 16.9 to 26.1 were obtained when cooking was carried out for 1 hour. Mechanical properties of the unbleached pulp showed a high tensile, tear and burst index for pseudo stem. | ||
