My TAPPI Story: Naomi Gehling
J. H. Klungness, M. S. Sykes, Aziz Ahmed, Said AbuBakr--Significant paper strength loss occurs when never-dried bleached kraft pulps are dried prior to paper manufacture. This loss in strength is a problem for the use of dried market pulp and recycled papers. The objectives of this study were to investigate the effect of fiber loading on restoring the water retention value (WRV) to once-dried bleached chemical kraft hardwood pulp and to explore the possibility of preventing the loss in WRV resulting from drying by fiber loading never-dried pulp. We fiber-loaded pulps on a laboratory scale, prepared handsheets, and measured WRV and Canadian Standard Freeness (CSF). Our results show that fiber loading restores WRV and increases the CSF of once-dried bleached kraft hardwood pulp. Fiber loading prior to drying also prevents loss in WRV when the pulp is dried.
