Investigation and Comparison of Bagasse Soda Pulps Properties Bleached with Total Chlorine Free (TCF) and Elemental Chlorine Free (ECF) Stages

The objective of this research was accomplished on the effects of total chlorine free (TCF) and elemental chlorine free (ECF) bleaching on optical and mechanical properties of bagasse soda pulps. For this purpose, some unbleached bagasse soda pulps were randomly selected from Ahvaz Pars industry. Th...

Then these pulps were bleached with one, two and three P, OP, OPY, O(Ep)P, EHP and O(Ep)H bleaching stages by using oxygen(O) hydrogen peroxide(P), alkali extraction with hydrogen peroxide(Ep), sodium hypochlorite(H) and sodium dithionite(Y).
