Abstract

Method for manufacturing an outsole for a footwear article. Method for producing an outsole for a footwear article, comprising the following successive steps: supply E01 comprising the following substeps: supply E02 of at least one liquid composition comprising a water-soluble binder and a water-based solvent in which the binder is dissolved; supply E03 of a filler consisting of loose fibers and / or a powder, at least 5% by weight of the filler being of bio-based origin; supply E04 of a support having a deposition surface; formation E05 on the deposition surface of a composite layer consisting of a liquid composition and a filler, comprising the following substeps: spraying E06 on the deposition surface of a liquid composition; and spraying E07 on the deposition surface of a filler;the spray substep E07 of a filler being simultaneous with or subsequent to the spray substep E06 of the liquid composition; drying E08 of the composite layer and polymerization of the water-soluble polymer by evaporation of water at atmospheric pressure; and repetition E09 at least once of the formation E05 and drying E08 steps of a composite layer, and formation of a wear layer on the deposition surface.
