Title
(EN) TISSUE PAPER WITH REDUCED FIBER AND METHODS OF MANUFACTURE
(FR) PAPIER OUATÉ À FIBRES RÉDUITES ET PROCÉDÉS DE FABRICATION
Abstract
(EN)
Tissue paper of the disclosure exhibits advantageous softness and bulk at a basis weight less than that of basis weights found in currently available commercial tissue products, while delivering adequate strength for machine runability and consumer usage. This tissue is a lightweight paper that comprises a fiber core with up to 60% mechanically fibrillated fibers and a retention or drainage aid such as a cationic polyacrylamide polymer that facilitates drainage, softness, and bulk. This approach can reduce the fiber content of tissue products significantly while delivering the desired strength and other critical properties.
(FR)
Le papier ouaté de l'invention présente une souplesse et un volume avantageux à un poids de base inférieur à celui des poids de base constatés dans des produits en papier ouaté commerciaux actuellement disponibles, tout en fournissant une résistance adéquate pour l'aptitude au roulage par machine et l'utilisation du consommateur. Ce papier ouaté est un papier léger qui comprend un cœur de fibre avec jusqu'à 60 % de fibres fibrillées mécaniquement et un adjuvant de rétention ou de drainage tel qu'un polymère polyacrylamide cationique qui facilite le drainage, la souplesse et le volume. Cette approche peut réduire significativement la teneur en fibres de produits en papier ouaté tout en délivrant la résistance souhaitée et d'autres propriétés critiques.
