ABSTRACT:
A method of manufacturing a press felt, a press section, and a press felt. The press felt comprises a base structure (11), a batt fibre layer (12) being attached to a first, web-side surface (B) of the base structure. Further, the structure of the press felt is compacted by treating it with a polymer material at least on the side of the first felt surface (B). After the polymer treatment, the surface of the felt is ground smooth.
