Indigenous Cellulosic Raw Materials for the Production of Pulp, Paper and Board Part XI - Chemical Pulps from <I>Andropogon contortus</I>, Linn.(<I>Kusal</I> Grass)

Abstract

Laboratory experiments on the preparation of chemical pulps by the soda and sulphate processes from Andropogon contortus, Linn., syn. Heteropogon contortus (Linn.) Roem. and Schult. (kusal grass) are described. Higher quantities of chemicals are required for the production of pulps from this grass than from sabai grass (Eulaliopsis binata). The pulps from this grass are short-fibred and, therefore, may require to be used in admixture with a long-fibred pulp such as sabai grass or bamboo pulp for the production of writing and printing papers. The economic utilization of this grass for the manufacture of paper will depend upon the price at which it will be available at factory site.
