Abstract

The aim of this study was to investigate the effect of ECF bleaching on optical and mechanical properties of bagasse Soda pulp. For this purpose, some soda unbleached pulps were randomly selected from Pars mill. Then these pulps were bleached using OD(Ep)P and OD(Ep)D sequence. The hand sheets with 70 gr/m2 were prepared from soda unbleached and bleached from EH(control), OD(Ep)P and OD(Ep)D pulps. Then the optical and mechanical properties were measured according to TAPPI Standard test methods. The results showed that residual lignin and kappa number was decreased following above-mentioned of bleaching stages. The brightness, greenness and K/S ratio were increased in bleached bagasse Soda pulps. In different treatments, the brightness, opacity, absorbance coefficient, burst, breaking length, tensile, tear strength were determined to be increased in OD(Ep)P and OD(Ep)D as compared with EH (control) mill bleaching stages. In general, OD(Ep)P sequence was better, than OD(Ep)D and both were superior to EH (control) mill stage in majority of measured properties.
