Pulping characteristics of Populus triplo wood

Abstract

In this reseach, chemical, anatomical and pulping properties of 12 years old Populus.triplo of adapting plan and quantity properties of this tree from karaj research station were investigated.The average of fiber length ,diameter ,lumen and thickness of cell wall 1.27 mm ,31.88 um, 23.54 um and 4.22 um and cellulose ,lignin , Ext. and ash %53.74 , %22.87 , %1.8 and %1.5 were measured respectively.The yield and kappa number of pulps between 41.152% - 48% and 18.06 – 25.28 were measured.In 14% and 18% effective alcoholli, tearh index 9.307 mNm²/gr and 10.147 mNm²/gr were obtained.
