Indigenous Cellulosic Raw Materials for the Production of Pulp, Paper and Board - Part XX - Chemical Pulps from Eupatorium odoratum Linn. (Assam-lota)

Laboratory experiments on the sulphate pulping of Eupatorium odoratum (Assam-lota) are described. Assam-lota is short-fibred. Taking into consideration the yields of bleached pulps obtained under conditions found best among those studied, the total quantities of chemicals required for digestion are high. The bleach requirement is very high. Assam-lota does not seem to be an economical fibrous raw material for the production of white writing and printing papers.
