Abstract

In the present research , the effect of utilizing a mixture of Birch with Hornbeam & Beech species (in the comparison with sample CMP( 75% Hornbeam 25% Beech) , on the mechanical and optical properties of papers produced within the domain of Freeness degree (CSF) of 300 ml and 85% yield has been reviewed . The CMP was prepared in accordance with 85% yield condition , different cooking times (30-120 min) , temperature of 170°C and white liquor ratio to chips in 7 to 1 & 20% Sulfide based on chips dry weight at 4 levels of 10, 20, 30 & 100% Birch mixed with Birch and Hornbeam species. After defibration and preparation of 60gm hand sheets, the optical and mechanical properties of that were assessed. The results indicated that by increasing the percentage rate of Birch , the quality of the manufactured paper was also increased and the best strength and optical properties were related to the 30 & 100% consumption rates of Birch in mixture with Beech and Hornbeam species.
