An impulse-dried paper having a three-dimensional pattern of alternating raised and recessed portions which is given the paper in connection with the impulse drying.

An impulse-dried paper having a three-dimensional pattern of alternating raised and recessed portions which is conveyed to the paper in connection with the impulse drying.

The weighted average value of AOX released from the productions of the pulps used in the eco-labelled tissue product must not exceed 0,12 kg/ADT paper.

A papermaking machine (10) for making uncreped through air dried paper having a forming section (20), a press section (30), and a drying section (50) is disclosed.

Amounts as low as 0.05 % by weight of the oven dried paper forming the pulp can allow increases in machine speeds of about 5 % or more.
