KW - kabuk KW - Kraft yöntemi KW - Kabuk N2 - Generally bark has a negative effect pulp and paper properties. In this study, paper pulp and hand sheets were produced from Wild dogwood (Cornus australis L.) using Kraft method. The cooking have been different conditions, chip / solution ratio 1/5, cooking temperature 170±2 °C by taking constant. Kraft method with the Na2S/NaOH, 18/20, 18/15, 18/10, 18/5 performed. Samples were used with and without bark in order to identify the negative impacts of the bark on pulp and paper production. In addition, it has been investigated whether the time of reaching the maximum temperature of K2 cooking is reduced from 120 minutes to 90 minutes, and the time and energy saving can be made. For all of the mechanical properties that were measured and pulp yield, the bark had a negative effect. But, this effect had not significant on mechanical properties at 95% significant level. On the other hand the bark had a negative effect on brightness and positive effects on opacity. These effects had significant at 95% significant level.
