Procedure for treating fibers and / or textile materials

Process for treating fibers and / or textile materials comprising the following steps: a) dissolution of two hydrophilic colloids in a solvent in which they are soluble and adding at least one asset to form a suspension of the asset in said solution, b) adjust the pH and / or dilute the previous suspension to cause coacervation of the colloids and their deposition on the asset that is encapsulated, c) increase the pH of the suspension and add a crosslinking agent to harden the microcapsules formed, d) cationize the microcapsules with a polymer or a cationic monomer, e) anchoring or fixing the microcapsules to the fibers and / or textile materials, f) drying the fibers and / or textile materials.
