Abstract

Laboratory experiments on the production of chemical pulps from ringal (Arundinaria sp.) for production of writing and printing papers by sulphate process are described. The average fibre length of pulp was 1.01 mm and average fibre diameter was 11 microns. Easy bleaching pulps in satisfactory yields could be prepared under suitable conditions of digestion.

Abstract

Laboratory expeciments on the production of chemical pulps from Ecualyptus robusta for production of writing and printing papers by sulphate process are described. The average tiher length of the pulp was 0.90 mm and the average fibre diameter was 0.010 mm. Easy bleaching pulps in good yield and satisfactory strength properties could be prepared under suitable conditions of digestion.

Abstract

Systematic investigations were carried out on laboratory scale on three Nagaland grasses, viz., thatch (Imperata cylindrica), khagra (Neyraudia reynaudiana) and bhutang (Saccharum procerum) for finding the suitability of soda pulps prepared from them for production of writing and printing papers. It was found that except for khagra top portion, all three grasses were suitable. When pilot plants trial were carried out to confirm the laboratory trials, it was found that bhutang top portions also not suitable.
