Investigation of Optical and Mechanical Properties of Bleached Chemi-mechanical Pulps (CMP) with Oxygen, Hydrogen Peroxide and Sodium Dithionite Stages

This study and it aim was accomplished on the effect of TCF bleaching on optical and mechanical properties of CMP pulp. For this purpose, some unbleached CMP pulps were randomly selected from Mazandaran Wood and Paper Industries (MWPI). Then these pulps were bleached with two and three OP, OPY, PY a...
