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

Integration of the relative rate of reaction over a period of time during the cooking cycle of wood to obtain a single number that can be used to determine the degree of cooking that has taken place. In the case of batch-type digesters, it is sometimes used to determine when the cook is finished and the time to "blow" the digester.  1, record 2, English, - H%20factor

[Chimie du procédé kraft] (...) En assignant de façon arbitraire une vitesse relative de réaction de 1 par 100°C, une méthode a été élaborée pour exprimer la durée de cuisson et la température sous forme d'une seule variable. Si on trace un diagramme de la vitesse relative de réaction en fonction de la durée de cuisson (exprimée en heures), l'aire comprise sous la courbe est caractérisée comme étant le facteur H. On peut appliquer le facteur H à la régulation de la cuisson, surtout lorsqu'on observe des variations de la température pendant l'opération.  1, record 2, French, - facteur%20H
