Title
(EN) FIBROUS STRUCTURE PRODUCTS COMPRISING LAYERS EACH HAVING DIFFERENT LEVELS OF CELLULOSE NANOPARTICLES
(FR) PRODUITS À STRUCTURE FIBREUSE COMPRENANT DES COUCHES COMPRENANT CHACUNE DIFFÉRENTS NIVEAUX DE NANOPARTICULES DE CELLULOSE
Abstract
(EN)
A fibrous structure having at least two layers is disclosed. Each of the at least two layers has a mixture of structural fibers selected from the group consisting of softwood fibers, non-wood fibers, natural non-cellulosic fibers, man-made cellulosic or non-cellulosic fibers, hardwood fibers, recycled fibers, and mixtures thereof. Each of the at least two layers are disposed in a face-to-face relationship. A second layer of the at least two layers has from about 0.05 percent to about 20 percent by weight of the second layer of cellulose nanoparticles.
(FR)
L'invention concerne une structure fibreuse comprenant au moins deux couches. Chacune des au moins deux couches possède un mélange de fibres structurelles sélectionnées dans le groupe constitué de fibres de bois tendre, de fibres non ligneuses, de fibres non cellulosiques naturelles, de fibres cellulosiques ou non cellulosiques artificielles, de fibres de feuillus, de fibres recyclées et des mélanges de celles-ci. Chacune des au moins deux couches est disposée dans une relation face à face. Une seconde couche des au moins deux couches comprend d'environ 0,05 pour cent à environ 20 pour cent en poids de la seconde couche de nanoparticules de cellulose.
