    Abstract: La invención se refiere a un método para elaborar un material de red no tejido compuesto que comprende extruir filamentos continuos desde un hilador, extraer los filamentos por una unidad de disminución de ranura en filamentos continuos delgados, formar una red de filamentos continuos no enlazados sin termoenlaces a medida que los filamentos se colocan, hidroenredar la red que comprende filamentos hidroenredados continuos junto con fibras cortas formadas de espuma o húmedas que comprenden fibras naturales y/o sintéticas o fibras cortadas para integrarse y enlazarse de manera mecánica y formar un material de red no tejido compuesto térmicamente no enlazado y se crea un ambiente húmedo en la formación y colocación de los filamentos continuos por las etapas de colocar los filamentos en una superficie ya húmeda, manteniendo el ancho de la salida de la unidad de disminución de ranura abierta por más de 65 mm y agregar líquido en la salida de la unidad de disminución de ranura.

    Abstract: Method of producing a paper having a three-dimensional pattern of alternating raised and recessed portions which has been provided in connection with impulse drying, at which the wet paper web (10) is passed through at least one press nip (12) comprising a rotatable roll (13) which is heated and that the paper web during the passage through the press nip is given a three-dimensional pattern of alternating raised and recessed portions either by means of a pattern wire, band or belt and/or by a pattern on the heated roll (13) and where the paper web (10) after said press nip (12) is led around an essential part of the periphery of the heated roll (13) in order to provide an additional drying of the paper web while this is still in contact with said three-dimensional pattern.
