Chlorine Dioxide Bleaching Properties of Sugarcane Bagasse Pulp and Oil Palm Trunk Pulp

Abstract

Soda-AQ pulp made from sugarcane bagasse (SCB) and oil palm trunk (OPT) were bleached in element chlorine free (ECF) sequence. Bleached SCB and OPT pulp was achieve higher brightness than 85.0% ISO. Viscosity of SCB bleached pulp and OPT bleached pulp were achieved 18-27 cPs and 18-26 cPs. In 7.8% active chlorine dioxide addition, bleached SCB pulp was shown 88.7% ISO brightness and 20.4 cPs viscosity. And bleached OPT pulp was shown 88.5% ISO brightness and 18.8 cPs viscosity with 7.8% active chlorine dioxide addition.
