Abstract : Five materials were applied to either a kraft pulp furnish or to a kraft paper and were removed by conventional removal processes. Uncontaminated kraft paper subjected to the same removal processes determined that the process, not the contaminant, was responsible for changes in sheet properties. Handsheet tensile properties, an indication of fiber bonding, and zero-span tensile tests, a measure of fiber strength, are reported. Aqueous polyethylene removal and deinking processes restored fiber bonding and strength almost to their initial levels. Wet strength removal, hot melt, and polyethylene solvent extractions resulted in fiber property reductions similar in magnitude to that of the recycled control. Asphalt dispersion caused the largest decrease in fiber properties. (Modified author abstract)
