Abstract
The objective of this secondary fiber research was to investigate the use of fiber fractionation to increase the utilization of office recovered paper by upgrading the quality of the fiber and thus minimizing the negative effects of recycling. Mixed office waste was collected, pulped, and cleaned. Handsheets were formed, repulped, and reformed to obtain pulps representing four recycles. A portion of the pulp from each recycle was fractionated to obtain long and short fiber fractions. Fractionation was successful in upgrading the long fiber component. Kajaani fiber analysis showed that the long fraction contained a significant portion of higher-grade papermaking fiber. Strength indexes were substantially enhanced by fractionation.
