Abstract
La présente invention concerne une nappe fibreuse et son procédé de préparation. La nappe fibreuse comporte une nappe de base comprenant une charge, éventuellement revêtue d'une couche de revêtement contenant du pigment. Selon l'invention, 5 à100 % de la charge dans la nappe de base est constitué de fibrilles cellulosiques ou lignocellulosiques avec des particules de diffusion de lumière déposées sur celles-ci. Les fibrilles cellulosiques ou lignocellulosiques revêtues constituent au plus environ 70 % du poids de la nappe de base. La nappe de base selon l'invention comprend plus de 20 % d'agents de rétention que ne contient une nappe ayant la même composition mais dans laquelle plus de 90 % de la charge est constitué de particules de charge connues en soi.
