Zusammenfassung:A fabric structure used to make textured tissue or towel or nonwovens is disclosed. The structure provides for being permeable to air and water for enhanced dewatering as compared to an impermeable belt, comprising a sheet contact surface having a pattern including a series of raised land areas and corresponding depressions that impart a texture to the tissue or towel or nonwoven, and a series of voids that allow passage of both water and/or air from the fabric surface into and/or through the structure. The voids are only in the land area, in the depressions or in both land area and the depressions. A specific pattern of lands/depressions/voids may aid sheet transfer to the Yankee cylinder and consequently, uniform creping. The structure would cause minimum sheet rewet compared to a woven porous structure or a conventional press fabric. L'invention concerne une structure en tissu utilisée pour la fabrication de mouchoirs, serviettes ou non-tissés texturés, la structure étant perméable à lair et à leau, comportant une surface de contact avec la feuille dotée dun motif comprenant une série de zones planes surélevées et de creux correspondants prévue pour conférer une texture au mouchoir, à la serviette ou au non-tissé, et une série de perforations débouchantes prévues pour permettre le passage de leau et / ou de lair provenant de la surface du tissu dans et / ou à travers la structure.
