Bamboo as Raw Materials for Dissolving Pulp with Environmental Friendly Technology for Rayon Fiber

Abstract Dissolving pulp raw material for rayon in Indonesia is wood. The limited availability of wood, nonwood is available in large numbers such as bamboo. Bamboo fibre has long fibre. A study for making of dissolving pulp of four types of bamboo such as Apus (Gigantochloa apus), Petung (Dendrocalamus asper), Mayan (Gigantochloa robusta) and Sembilang (Dendrocalamus giganteus). The pulping process is Pre-hydrolysed-Kraft and bleaching of pulp with environmental friendly technology (Elemental Chlorine Free and enzyme). Pulp bleaching yield between 94-97% is still high. Cellulose content bamboo dissolving pulp is higher than requirements Indonesian standard specification SNI (> 94%).
