Method for producing a sound-absorbing panel

Abstract

Method for producing of a sound-absorbing panel, including a step of preparing a predetermined amount of cellulose fibres and a step of immersing the cellulose fibres in a first water basin to form a cellulose pulp. The method then includes a step of preparing a predetermined amount of textile fibres and a step of mixing, in water, the cellulose pulp with the textile fibres to obtain a final pulp and a step of depositing the final pulp on a forming mould. The method then includes a step of pressing at least the final pulp in order to cause an at least partial removal of the water contained in the final pulp making a fibre mat and a step of drying the fibre mat so as to cause evaporation of the water remained in the fibre mat making a sound-absorbing panel.
