Claims (14)

  1. Procédé de préparation d'une nappe fibreuse comprenant des fibres textiles longues, selon lequel on forme une matière première fibreuse en dispersant ces fibres dans un milieu formant véhicule non moussé, consistant essentiellement en eau et en un épaississant associatif, la teneur en épaississant dans la matière première fibreuse étant de 0,45 g à 22,0 g/kg (de 1 à 50 livres par tonne) de fibres par rapport au poids à sec des fibres, caractérisé en ce que l'épaississant associatif comprend un copolymère séquencé d'uréthanne dérivé d'oxyde d'éthylène ou un éther d'hydroxyéthylcellulose à chaîne latérale alkyle en C₁₀ à C₂₄, et on fournit l'a matière première fibreuse non moussé selon une consistance de 0,05 à 0,5 % en poids de fibres, à la toile métallique d'une machine de fabrication de papier afin de former une nappe fibreuse.

  6. Procédé selon l'une quelconque des revendications 1 à 5, caractérisé en ce que la nappe comprend exclusivement des fibres textiles longues.
  7. Procédé selon l'une quelconque des revendications 1 à 5, caractérisé en ce que la nappe comprend un mélange de fibres cellulosiques et de longues fibres textiles.
  8. Procédé selon la revendication 7, caractérisé en ce que les longues fibres textiles sont des fibres synthétiques.
  9. Procédé selon la revendication 7 ou 8, caractérisé en ce que le rapport des longues fibres textiles aux fibres cellulosiques est de 0,5 à 1.
