Abstract

processo para a produção de um substrato compreendendo celulose regenerada e um substrato produzido em concordância com o processo. a presente invenção se refere a um processo para a produção de um substrato. em concordância com a presente invenção, o processo compreende as etapas de: - provisão de um substrato compreendendo fibras celulósicas; - adição de uma solução compreendendo fibras dissolvidas e/ou parcialmente dissolvidas para a superfície de substrato; - adição de uma solução de regeneração para a superfície do substrato de maneira que as fibras dissolvidas e/ou parcialmente dissolvidas se regeneram sobre a superfície do substrato; e - secagem do substrato. a presente invenção também se refere a um substrato produzido em concordância com o processo anteriormente descrito.A process for producing a substrate comprising regenerated cellulose and a substrate produced in accordance with the process. The present invention relates to a process for producing a substrate. In accordance with the present invention, the process comprises the steps of: providing a substrate comprising cellulosic fibers; adding a solution comprising dissolved and / or partially dissolved fibers to the substrate surface; adding a regeneration solution to the substrate surface such that dissolved and / or partially dissolved fibers regenerate on the substrate surface; and - drying the substrate. The present invention also relates to a substrate produced in accordance with the process described above.
