There is disclosed a novel cellulosic web and a method for its manufacture. The web is fabricated of fibrous material and is characterized by one of its surfaces being nubby. Such web is formed by the deposition of fibers from an aqueous slurry onto the surface of a multiplex forming fabric defining pockets in one surface thereof, under conditions of flow and rate of water removal that establish high shear fluid flow and result in the orientation of fibers and/or fiber segments at an angle with respect to the plane of the forming fabric. The resultant web has a high apparent bulk and good absorbency and strength properties.
Nouvelle bande cellulosique et méthode de fabrication. La bande est fabriquée d'un matériau fibreux dont l'une des surfaces est munie de boutons de fibre. Cette bande est formée par la déposition de fibres d'une boue aqueuse sur la surface d'une toile de formation multicouche définissant des pochettes sur une des surfaces, sous des conditions de débit et de vitesse de retrait d'eau qui établissent un courant élevé de rotation du fluide et entraînent l'orientation en angle des fibres et/ou des segments de fibre par rapport au plan de la toile de formation. La bande résultante présente une masse volumique apparente élevée et des caractéristiques de bonne capacité d'absorption et de solidité.
