3.1 Fiber Morphology of Bamboo
The bamboo fiber length was showed in Table 2. The table shows the value of morphology of four type of bamboo fiber such as Apus, Mayan, Petung and Sembilang based on the assessment criteria for wood pulp and paper raw materials7. The fiber length four types of bamboo belong to the long fibers class, range from 2.34 to 3.24 mm. The long fiber of the wood or non wood pulp has produced a high strength and high cellulose content. Apus bamboo diameter and fiber wall thickness is smaller than Petung, Mayan and Sembilang bamboo. Thinwalled fiber easily refined to produce pulp and paper sheet are more solid and better bursting strength and reduces the refining power to fibrillation compared with the thick-walled fiber. Conversely, thick-walled fiber will produce sheet that has high tear strength, but low tensile strength8.
