Title (EN) PROCESS FOR MAKING PAPER PRODUCTS COMPRISING NANOFILAMENTS
(FR) PROCÉDÉ DE FABRICATION DE PRODUITS DE PAPIER COMPRENANT DES NANOFILAMENTS
Abstract:
(EN) Processes for making absorbent paper webs comprising the steps of (a) providing a papermaking furnish comprising: from 45% to 90% of a refined softwood pulp fiber mixture comprising: from 20.0% to 88.5% of softwood pulp fiber, and from 0.05% to 5.0%> of a strengthening additive; and from 10% to 55% of a hardwood pulp fiber mixture comprising: from 9.9% to 54.9% of hardwood pulp fibers, and from 0.05% to 20.0% of cellulose nanofilaments; and (b) forming a wet fibrous web from said paper making furnish; (c) drying said web until said web contains not more than 10% by weight moisture.
(FR) L'invention concerne des procédés de fabrication de bandes de papier absorbant comprenant les étapes suivantes : (a) apport d'une pâte de fabrication de papier comprenant : de 45 % à 90 % d'un mélange de fibres de pâte de bois tendre raffinée comprenant : de 20,0 % à 88,5 % de fibres de pâte de bois tendre, et de 0,05 % à 5,0 % d'un additif de renfort ; et de 10 % à 55 % d'un mélange de fibres de pâte de bois dur comprenant : de 9,9 % à 54,9 % de fibres de pâte de bois dur, et de 0,05 % à 20,0 % de nanofilaments de cellulose; et (b) la formation d'une bande fibreuse humide à partir de ladite pâte de fabrication de papier ; (c) le séchage de ladite bande jusqu'à ce que ladite bande ne contienne pas plus de 10 % en poids d'humidité.
