Investigation of processing parameters and properties of date palm fiber for the production of quality fiber boards

Abstract

The anatomic properties of date fiber and its suitability in the production of alternative material for structural engineering application in the construction industry were investigated. Sample preparation was conducted in accordance with TAPPI Standard T12 – OS – 75, which specifies that samples be grinded to a fine particle size to permeate 0.4mm screen and retained on a 0.6mm screen. The moisture, lignin, extractives, alpha cellulose, and ash content, fiber dimensions, and weight percentage of cross and Bevan cellulose were all investigated. Pulping operation was further carried out which resulted in the production of good quality pulps, and subsequent production of various grades of fiber boards. Testing was carried out at 200C and 65% relative humidity; the board samples were conditioned in this atmosphere for about 3 ½ hours before testing. Pulp yield was exceptionally high. The impact of sodium silicate and carboxyl methyl cellulose (CMC) yielded fiber boards which displayed good strength properties. The processing parameters obtained affirm that date fiber offer considerable potentials in the production of quality boards that offer alternatives to wood.
