| Abstract: | Mixed kraft pulp of E. tereticornis, B. aurandacea and P. roxumberghi in the ratio of 80: 15:05 was bleached by total chlorine free bleaching sequences (TCF). Various bleaching sequences like OZ, OQP, OQPP, OZQP, OQPZ and OZQPP were used to produce pulp of brightness of + 90 per cent. The effect of bleach chemicals on polysaccharide was also studied by determining the viscosity of finally bleached pulp. The bleaching sequences were also interchanged in order to observe the effect on brightness and pulp viscosity. |
