During delignification, there is also a corresponding reduction in pulp viscosity.... If pulp viscosity is allowed to fall below a critical level, the pulp strength drops dramatically. Maintenance of pulp viscosity is the principal reason that the kraft cook must be terminated at a point where a substantial level of residual lignin remains with the fibers. A derivation termed the G-factor(exactly analogous to the H-factor) can be applied for viscosity reduction, i. e., combinations of time and temperature that give the same G-factor can be expected to produce pulp with the same viscosity. Since the G-factor increases more rapidly with temperature than the H-factor, it follows that higher cooking temperatures have a proportionally greater effect on viscosity reduction.  1, record 1, English, - G%2Dfactor
