Abstract
La présente invention a pour objet un procédé de préparation de fibres végétales naturelles, dans le but de leur permettre de remplacer les fibres d'amiante, caractérisé en ce qu'on imprègne les fibres à l'aide d'une solution liquide de colle à bois, présentant une concentration suffisante pour qu'après séchage, les fibres puissent être broyées.
