DETERMINATION OF PAPER PRODUCTION CONDITIONS OF WILD CHERRY HEARTWOOD AND SAPWOOD

Sapwood and heartwood obtained from the same tree presents different characteristics in terms of paper manufacturing. In this study, paper pulp and handsheets were produced from Wild cherry (Cerasus avium (L.) Moench) sapwood, heartwood and both by using Kraft method. Based on previous studies, twelve cookings have been carried out with the parameters of 1/5 chip-liquor ratio, 170±2 °C cooking temperature, 60 minutes reaching time to maximum temperature, active alkali / sulfidity ratios as 20/26, 22/24, 24/22, 26/20, 80 minutes cooking time at the maximum temperature. It is concluded that general purpose paper can be manufactured from heartwood and sapwood of Wild cherry wood by using kraft pulping method. According to the results, optimum active alkali/sulfidity ratio were determined as 20/26.
