    Description

    The results of this investigation showed that physical properties of sheets made from hardwood fiber are very dependent upon fiber morphology. Chemical variation of pulp fibers did not exhibit an influence on sheet strength. Of the morphological characteristics investigated, those contributing the most were fiber length, L/T ratio, and fibril angle. Hardwood fines (parenchyma cells) were detrimental to bursting and tensile strength. Vessel elements, in amounts found originally in typical hardwood furnishes, had no effect on tensile strength.
