The Effect of ECF Bleaching on Optical and Mechanical Properties of Bagasse Soda Pulp

This study and it aim was accomplished on 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 with OD(Ep)P and OD(Ep)D stages by oxygen, chlorine diox...
