Title
(EN) METHODS FOR THROUGH-FLUID BONDING NONWOVEN WEBS
(FR) PROCÉDÉS POUR LIAISON PAR FLUIDE DE BANDES NON TISSÉES
Abstract
(EN)
Methods for manufacturing through-fluid bonded continuous fiber nonwoven webs are provided. The method may include providing a through-fluid bonding oven. The through-fluid bonding oven may have a first porous member and a second moving member. An intermediate continuous fiber nonwoven web may be conveyed into the through-fluid bonding oven intermediate the first and second moving porous members. A first surface of the intermediate continuous fiber nonwoven web may be in face-to-face contact with the first porous member. A second surface of the intermediate continuous fiber nonwoven web may be in face-to-face contact with the second porous member. A heated fluid may be flowed through the first and second porous members and the intermediate continuous fiber nonwoven web to create a continuous fiber nonwoven web.

L'invention concerne des procédés pour fabriquer des bandes non tissées à fibres continues liées par fluide. Le procédé peut consister à fournir un four de liaison par fluide. Le four de liaison par fluide peut avoir un premier élément poreux et un second élément mobile. Une bande non-tissée intermédiaire à fibres continues peut être transportée dans le four de liaison par fluide intermédiaire entre les premier et second éléments poreux mobiles. Une première surface de la bande non-tissée intermédiaire à fibres continues peut être en contact face à face avec le premier élément poreux. Une seconde surface de la bande non-tissée intermédiaire à fibres continues peut être en contact face à face avec le second élément poreux. Un fluide chauffé peut être amené à s'écouler par les premier et second éléments poreux et par la bande non-tissée intermédiaire à fibres continues pour créer une bande non-tissée à fibres continues.
