摘要

The invention relates to a dried market paper pulp manufactured from a raw material of wood chips, which is characterised in that the fibres therein are coloured by means of a colouring agent added to the fibres while they still are in a water suspension, but prior to final drying. The paper pulp is thereafter advantageously used for manufacturing high-quality, dry-formed tissue paper having a uniform colour.
