AI Technical Summary
Technical Problem
Existing textile production processes using spray technology are highly polluting, toxic, and environmentally unfriendly due to the use of polymers and solvents derived from hydrocarbons, requiring imported raw materials and generating significant waste.
Method used
A method utilizing bio-based fillers in powder and/or fiber form, a predominantly water-based solvent, and a water-soluble binder to produce textiles, minimizing waste and environmental impact while allowing local production and rapid, precise shaping.
Benefits of technology
The process significantly reduces environmental and ecological impact by using renewable materials, minimizing waste, and enabling local production with controlled thickness and shape, while maintaining textile quality and functionality.

Abstract
The invention relates to a method for producing a textile, the method comprising the following successive steps: - a provision step (E01) comprising the following sub-steps: o a provision sub-step (E02) of providing at least one liquid composition comprising an aqueous solvent and a binder comprising at least one polymer that is water-soluble and / or able to form a dispersion in water; o a provision sub-step (E03) of providing a filler consisting of loose fibers and / or a powder, at least 5% by weight of the filler being of biobased origin; o a provision sub-step (E04) of providing a support having a deposition surface; - a formation step (E05) of forming, on the deposition surface, a composite layer consisting of a liquid composition and a filler, the formation step (E05) comprising the following sub-steps: o a spraying sub-step (E06) of spraying a liquid composition onto the deposition surface; and o a spraying sub-step (E07) of spraying a filler onto the deposition surface; o the spraying sub-step (E07) of spraying a filler being simultaneous with or subsequent to the spraying sub-step (E06) of spraying the liquid composition; - a drying step (E08) of drying the composite layer resulting from the formation step (E05), solidifying the binder of the composite layer by evaporating water at atmospheric pressure and fixing the filler by means of the binder; - a repetition step (E09) of repeating, at least once, the step (E05) of forming and the step (E08) of drying a composite layer, and forming a textile on the deposition surface; and - a removal step (E13) of removing the textile from the deposition surface.
