Abstract

a presente invenção refere-se a processo para a produção de um substrato revestido compreendendo fibras celulósicas, o processo compreendendo as etapas de: i) prover um primeiro substrato compre-endendo fibras celulósicas e tendo um teor seco de menos que 50%; ii) aplicar uma composição de revestimento ao primeiro substrato em uma quantidade de mais que 5 g/m2, calculada como peso seco da composição de revestimento, em que a composição de revestimento compreende: - celulose microfibrilada (mfc), e - opcionalmente um agente de retenção de água selecionado de carbóxi metil celulose (cmc), poliacrilamida aniônica (a-pam), poliacrilatos de sódio, deriva-dos de ácido poliacrílico, goma guar, alginato, mfc preparada de fibras carbóxi metiladas, mfc preparada de fibras oxidadas, mfc preparada de fibras funcionalizadas-cmc, e/ou combinações dos mesmos; e iii) retirar mecanicamente água do primeiro substrato. o presente processo provê um processo de revestimento eficiente em energia que pode ser realizado em linha.
