Title
(EN) FUNCTIONAL INSERT FOR NONWOVEN MATERIALS
(FR) INSERT FONCTIONNEL POUR MATÉRIAUX NON TISSÉS
Abstract
(EN)
The present teachings include a fibrous structure including one or more nonwoven layers comprising a fibrous web layer and one or more functional insert layers for providing additional properties to the material. The one or more of the nonwoven layers and one or more functional insert layers may be lapped together to form a vertically lapped structure. The present teachings also include a method of forming the fibrous structure.
(FR)
La présente invention concerne une structure fibreuse comprenant une ou plusieurs couches non tissées comprenant une couche de toile fibreuse et une ou plusieurs couches d'un insert fonctionnel pour fournir des propriétés supplémentaires au matériau. La ou les couches non tissées et une ou plusieurs couches de l'insert fonctionnel peuvent être rodées ensemble pour former une structure à chevauchement vertical. La présente invention concerne également un procédé de formation de la structure fibreuse.
