Abstract

The invention discloses a method for producing a three-dimensional molded article from cellulose fibers, comprising the steps of:-providing a pulp molding composition;-molding a three-dimensional precursor structure from said composition wherein said structure comprises a dry content between 15-80wt%;-providing an aqueous suspension comprising microfibrillated cellulose and wet strength agent;-applying the aqueous suspension onto at least one face of said precursor structure to create a surface barrier layer on said structure; and-dewatering and drying said molded precursor structure under elevated temperature >150°C to a dry content of ≥88wt%, preferably ≥94wt%, more preferably ≥96% to achieve the threedimensional molded article.
