Abstract
The absolute density of plant fibres excludes all pores and lumen and therefore is a measure of the solid matter of the fibres. On the other hand the bulk density which is being discussed here includes all the solid matter and the pores of the fibres. In this work the apprent density of the fibre was measure by using the Archimedes principles which involves the immersion of a known weight of fibre into a solvent of lower density than the fibre. Toluene with a density of about 860 kg/m3 was choosen as a solvent. It was choosen because it is less carcinogenic compared to benzene which is commonly used as a solvent in density measurement of natural fibres. A tuft of fibre was weighed and recorded as Wfa. The fibre was then immersed in toluene which wetted the fibre and made to rest on the weighing pan submerged in the solvent and the weight of the immersed fibre was recorded as Wfs. The apparent density was the calculated using the equation below. All the measurements were taken at room temperature. The fibre samples were not oven dried prior to measurement.
