Abstract

Un procédé permet de fabriquer une natte (24) fibreuse stockable et maniable composée de fibres de cellulose (1) et de fibres thermoplastiques (10), notamment de fibres de polyester, et/ou de fibres naturelles d'origine végétale, et contenant un liant duroplastique (5) à base de matières plastiques. Sous l'effet de la chaleur et de la pression, et par le durcissement du liant duroplastique (5) pendant une étape ultérieure du procédé, ladite natte fibreuse (24) peut être comprimée de façon à former des pièces indéformables présentant des propriétés uniformes sur toute leur section transversale. A cet effet, les fibres de cellulose (1) sont imprégnées avec une solution du liant duroplastique (5), de préférence une solution de résine phénolique, puis séchées; les fibres séchées de cellulose (6) sont mélangées à sec avec des fibres thermoplastiques (10), telles que fibres de polyester, et/ou des fibres naturelles d'origine végétale; un non-tissé (21) est formé avec le mélange de fibres de cellulose (6) et de fibres thermoplastiques (10) et/ou de fibres naturelles d'origine végétale et le non-tissé (21) est renforcé par des aiguilles dans une machine à aiguilles (23).
