Kiri(Paulownia elongota)Wood as a Raw Material for Paper Production
The chemical,morphological and anatomical aspects of Kiri(Paulownia elongota)wood have been determined.The lignin,holocelluiose and α-cellulose contents in Kiri wood were comparable to those of some common non-wood and hardwood raw materials.Different chemical pulping procedures were applied to Kiri wood to evaluate its pulping potential.Paper strength properties and acidic group content bound to the cell wall were determined.The alkali solubility,water solubility and alcohol-benzene extractive content were higher than those from wood and most non-woods.The fiber length of 0.83 mm was observed,which is close to low end of the hardwoods but fiber diameter was very big,similar to that of softwoods.The pulpability of Kiri wood has also been studied.The pulp yield and viscosity were very low and the kappa numbers were high.The strength properties were comparable to those of some wood and non-wood pulps.
