Title (EN) PARTICLE BINDING TO FIBERS
(FR) LIAISON DE PARTICULES A DES FIBRES
Abstract:
(EN) A binder is applied to particles (602) which are then combined with fibers (600) to bind the particles to the fibers (600). The particles (602) have functional sites for forming a hydrogen bond or a coordinate covalent bond. The fibers (600) have hydrogen bonding functional sites. The binder comprises binder molecules, the binder molecules having at least one functional group that is capable of forming a hydrogen bond with the fibers. A substantial portion of the particles (602) that are adhered to the fibers (600) may be adhered in particulate form by hydrogen bonds or coordinate covalent bonds to the binder, and the binder in turn may be adhered to the fibers (600) by hydrogen bonds. Fibers (600) containing particles (602) bound by this method are easily densified.
(FR) On applique un liant sur des particules (602) qui sont ensuite combinées avec des fibres (600) pour lier lesdites particules auxdites fibres (600). Les particules (602) présentent des sites fonctionnels destinés à former une laison hydrogène ou une liaison covalente de coordination. Les fibres (600) présentent des sites fonctionnels de liaison hydrogène. Le liant comprend des molécules de liaison présentant au moins un groupe fonctionnel pouvant former une liaison hydrogène avec les fibres. Une partie importante des particules (602) adhérant aux fibres (600) peuvent adhérer au liant sous une forme particulaire, par l'intermédiaire de liaisons hydrogène ou de liaisons covalentes de coordination, et le liant peut à son tour adhérer aux fibres (600) par l'intermédiaire de liaisons hydrogène. Les fibres (600) contenant des particules (602) liées selon cette méthode peuvent être facilement densifiées.
