CA 2279524

A process is disclosed for producing fibrous materials for the manufacture of cellulose, paper or wood materials by using at least one dicarboxylic acid dialkyl ester and/or a copolymer of polyester-polyether and/or fatty acid polyol monopolyester, dipolyester, tripolyester and or higher polyester. Fibrous materials with an improved quality and higher yield are thus produced.

Le procédé décrit sert à produire des matières fibreuses destinées à la fabrication de cellulose, de papier ou de matériaux en bois. On utilise à cet effet au moins un dialkylester d'acide dicarboxylique et/ou un copolymère polyester-polyéther et/ou monopolyester, dipolyester, tripolyester et/ou polyester supérieur de polyol d'acide gras. On produit ainsi avec un plus haut rendement des matières fibreuses de qualité améliorée.
