摘要：

In the present work, the transient i.e. time-dependent behaviour of residual lignin in softwood kraft pulp was experimentally tested step-wise in an industrial two-stage oxygen-alkali delignification process. Tho behaviour was characterized by leaching the pulps and dividing the residual lignin into four different fractions representing the wash loss lignin, easily leachable, slowly leachable and stagnant fractions of residual lignin in pulps.
