Investigation the properties of radiata pine (pinus radiata) wood kraft pulp and paper

In this study, pulp and handsheets characteristics of radiata pine wood kraft pulp was evaluated. The ratiata pine wood was collected from Chamestan Noor Research Station. Average dry and basic specific gravity of wood were determined as 0.342 and 0.308 g/cm3 and average fiber (tracheid) dimension...
