A method is provided for producing a soft and silky air-laid fibrous product. After the forming of a product a two-directional stretching is affected thereby establishing a fine mosaic pattern of invisible lines. In said lines the covalent bonds are maintained whereas the hydrogene bonds are neutralized. Hereby a very soft and silky product is obtained having a good hand and feel.

L'invention concerne un procédé de production d'un produit fibreux doux et soyeux formé par voie sèche. Après avoir formé un produit de base, on procède à l'étirage bidirectionnel formant ainsi un motif mosaïqué fin de lignes invisibles. On maintient les liaisons covalentes dans ces lignes pendant que l'on neutralise les liaisons hydrogène. On obtient ainsi un produit soyeux et doux présentant un toucher agréable.
