Pulping of Kenaf Bark - Soda Vs.sulphate

Abstract

Contrary to the long recognized superiority of wood sulphate pulps over wood soda pulps, it was observed that the yield and strength properties of soda and sulphate pulps from kenaf bark were approximately equivalent under identical cooking conditions. However,the two types of pulps differed in their response to bleaching. Soda pulp consumed higher bleaching chemical, but, showed lesser degradation than sulphate pulp, which is contrast consumed lesser bleaching chemical, but, showed considerable degradation under identical bleaching conditions.
