Disclosed is a method for producing a fibrous web exclusively from cellulose fibers having a natural origin. Said method comprises the following steps: a dry fiber layer having a substantially regular thickness is formed from loose fibers having a low moisture content; said fiber layer is pressed and embossed to obtain a fibrous web and form an embossed pattern; the fibrous web is moistened by means of a water-latex mixture having a high water concentration (75 to 99 percent by weight of water); and the latex is precipitated in a drying process while the fibers are bonded inside and outside the fiber bond zones.
L'invention concerne un procédé pour réaliser une bande fibreuse exclusivement en fibre de cellulose d'origine naturelle, ce procédé comportant les opérations suivantes : former une couche fibreuse sèche d'épaisseur sensiblement homogène en fibres individuelles à faible humidité, presser et gaufrer la couche fibreuse en une bande fibreuse avec application d'un motif, humidifier cette bande fibreuse avec un mélange d'eau et de latex à teneur élevée en eau (75 à 99 % en poids) et précipiter le latex par séchage en liant les fibres à l'intérieur et à l'extérieur des zones composites fibreuses.
