Indigenous Cellulosic Raw Materials for the Production of Pulp, Paper and Board - Part X. - Writing and Printing Papers from Panni Grass (Vetiveria zizanioides)

Laboratory experiments on the chemical pulping of panni grass (Vetiveria zizanioides) by the soda process are described. Pilot plant experiments on the production of chemical pulps and writing and printing papers are also included. A sample of writing paper made from a mixture of 60% of panni grass pulp and 40% sabai grass pulp is appended. These experiments have shown that panni grass can be used for making chemical pulp and that writing and printing papers can be made from a furnish containing a mixture of panni grass pulp and a long-fibred pulp such as sabai grass pUlp.
