Effect of refining of deinked pulp on the optical, physical and mechanical properties of paper

The effect of refining of recycled pulp on the optical, physical and mechanical properties of paper was investigated.The results showed that, except tear strength, all of mechanical strength of paper significantly increases by refining.While, by refining of recycled pulp the brightness increases but the opacity decreases.Also, caliper and roughness of paper decreases.Refining of recycled pulp result in increasing Porosity.
