Title
(EN) BICOMPONENT AND LONG FIBER PRODUCT DEFINITION
(FR) PROCEDES DE FABRICATION DE PRODUITS A FIBRES LONGUES COMPRENANT DEUX MATERIAUX
Abstract
(EN)
Numerous alternative methods of producing product definition in such thick, binderless wool packs (48) of long, single component, and particularly, bicomponent, glass fibers (16) are provided. The present methods are loosely grouped as those including a step which disturbs the fiber matrix, those including a step which adds an element to the fiber matrix, and those including a step of fusing fibers. The latter group of methods includes laser (94) and hot needle (90) fusing of fibers, while others include the addition of polymer fibers (96) and polymer material to long fibers (16) generally uniformly distributed in a binderless wool pack (48).
(FR)
L'invention concerne différents procédés de fabrication d'un produit se présentant sous la forme de bandes épaisses exemptes de liant (48) de fibres longues comprenant un seul matériau et, particulièrement, de fibres minérales (16) comprenant deux matériaux. Ces procédés se regroupent généralement d'après ceux qui comportent une étape de perturbation de la matrice en fibres, ceux qui comportent une étape d'apport d'un élément à la matrice en fibres ou ceux qui comportent une étape de fusion des fibres. Ce dernier groupe consiste à effectuer la fusion au laser (94) et la fusion thermique à l'aiguille (90) des fibres, tandis que d'autres consistent à effectuer l'apport de fibres polymères (96) et de matériau polymère à des fibres longues (16) généralement uniformément réparties dans une bande sans liant (48).
