Investigation on the Physical, Anatomical and Fiber Biometrical Properties in the Kiwi Residues

In this research, some chips of kiwi residues (Actinidia Spp.) from the west of mazandaran in north of Iran were randomly chosen. The samples were prepared to measure fiber biometrical, physical and anatomical properties by using franklin and ASTM standard test methods respectively. The results showed that kiwi residues had semi-ring porous wood, and group vessels with spiral thickening. The parenchymas were longitudinal and axial. There were a lot of rays in cross-section. The average of the fiber diameter, ray thickness, fiber length, runkel coefficient, dry density, basic density, shrinkage and porosity were 172 m , 17.6 m , 1371m , 116.6, 0.668gr/cm3, 0.564 gr/cm3,15.7 % and 55.1% percent, respectively. The results indicated that kiwi residues properties were as suitable as the hard woods. The results also pointed out that the wood from kiwi residues can replace some or all of the raw material for production of pulp and paper, fiber board , particle board, and other wood composition boards in the wood and paper industries.
