Title (EN) SIMPLIFIED PROCESS FOR MAKING THICK FIBROUS STRUCTURES
(FR) PROCEDE SIMPLIFIE PERMETTANT DE FABRIQUER DES STRUCTURES FIBREUSES EPAISSES
Abstract:
(EN) The invention relates to a process for making thick fibrous structures. More particularly, the invention relates to a simplified needle-forming process wherein loose fiber is accreted into a thick fibrous structure by repeatedly driving a multitude of felting needles into the loose fiber, the felting needles penetrating all the way through the fibrous material at the beginning of the process, and penetrating only part way through the fibrous material at the end of the process. The processes according to the invention eliminate one or more intermediate steps of forming coherent fibrous layers that were previously thought necessary in the prior art in order to form a thick fibrous structure.
(FR) L'invention a trait à un procédé servant à fabriquer des structures fibreuses épaisses. Plus particulièrement, l'invention a trait à un procédé simplifié de formage par aiguilles, dans lequel on agglomère des fibres déliées pour former une structure fibreuse épaisse en faisant passer de façon répétée une multitude d'aiguilles de feutrage à l'intérieur des fibres déliées. Les aiguilles de feutrage pénètrent de partout la matière fibreuse au début du procédé, et pénètrent seulement partiellement celle-ci à la fin du procédé. Les procédés de l'invention permettent d'éliminer une ou plusieurs étapes intermédiaires de formation de couches fibreuses cohérentes qui, dans les techniques existantes, sont nécessaires pour former une structure fibreuse épaisse.
