A densifying agent is applied to fibers in order to improve the densification properties of the fibers. The fibers have hydrogen bonding functional groups. The densifying agent are denser than the fibers to which the densifying agent is applied. The densifying agent can be organic or inorganic. The improved densification properties are observed without the presence of particles bound to the fibers or in the presence of particles that are not bound to the fibers. Softening agents can also be applied to the fibers in order to soften the fibers and articles including such fibers. Softening agents may be selected from the group of densifying agents.

La présente invention concerne un agent densificateur que l'on applique aux fibres pour en améliorer les propriétés de densification. Ces fibres présentent des groupes fonctionnels liant l'hydrogène. L'agent densificateur est plus dense que les fibres auxquelles il est appliqué. Il peut être organique ou inorganique. On observe une amélioration des propriétés de densification en l'absence de particules liées aux fibres ou en présence de particules non liées aux fibres. Des agents adoucissants peuvent aussi être appliqués aux fibres pour adoucir ces dernières ainsi que les articles fabriqués avec celles-ci. On peut choisir les agents adoucissants dans le groupe des agents densificateurs.
