Fiberboards from loblolly pine refiner groundwood: aspects of fiber morphology

Abstract

In tests with Pinus taeda L., most properties of wet formed hardboard were improved by using fiber refined from wood having short, slender tracheids with thin walls. A theoretical analysis suggested that the fibers fail in bending while under stress induced by the pressing operation. Sush bending failures improve conditions from hydrogen bonding, thus improving board properties. Tracheids having narrow diameters and thing walls flex easily and collapse readily. Short tracheids are more desirable than long tracheids because of a greater number of fiber crossings per unit weight in the pulp mat.
