Abstract: The invention relates to a method for producing an absorbent fiber product, starting with a parent fiber product that comprises fibers that, on the one hand, lie at a statistical distance from one another and, on the other hand, make contact with one another at contact points. The method comprises treating the parent fiber product with a fluid medium in such a way that the fibers are at least partially wetted and the fluid medium is then rapidly evaporated by irradiation, so that the evaporation pressure generated by the evaporating fluid medium has a kinematic effect on the fibers, which increases the distance between them. In this way the risk of inadvertent, in particular, thermal damage to the fibers is eliminated. Furthermore, the intrinsic fiber structure is left unaffected, or is only affected in a controlled manner. This prevents the uncontrolled destruction of the fiber structure and a detrimental effect on the fiber product, for example, to its tear resistance when wet.

Abstract: A tissue sheet is made using a modified wet pressing process employing an integrally sealed air press. After initial formation and conventional vacuum dewatering, the wet web may be conformed to the surface contour of a relatively coarse fabric to give the web a textured surface.

The web may be dried to substantially preserve its three-dimensional, throughdried-like texture. The process provides a web having an exceptionally high degree of bulk and absorbency not expected in wet-pressed products.
