The present invention concerns a method of optimization of the refining energy supplied by a refiner to a fiber composition during a refining operation, the refiner comprising at least two refining disks separated from each other by an adjustable gap. The invention also relates to a refining system adapted to the implementation of such a method.

A method for depositing, on a substrate, a composition of cellulosic fibers, includes preparing an aqueous suspension SA comprising at least cellulosic fibers, spraying, at a pressure no lower than 3 MPa, the aqueous suspension SA onto a substrate, wherein the spraying is carried out by means of a nozzle having a size between 0.05 mm and 3 mm, and obtaining a fibrous deposit DF on the substrate. The aqueous suspension SA includes at least 3% by weight of cellulosic fibers relative to the total weight of the aqueous suspension SA, and the aqueous suspension SA and the fibrous deposit DF have dry matter with identical composition.
