The invention relates to a method for producing a structured fibrous mat, comprising the following steps: a) injecting a dispersion comprising polymer(s) and/or non-spherical particles in a suitable liquid into a reaction chamber (4) comprising at least an inlet (9) and an outlet (8), b) coagulating the dispersion into a continuous wet thread (6) in the reaction chamber by the introduction of a co-flowing coagulation liquid into the reaction chamber (4), c) separating the liquid (5) from the continuous wet thread (6) at the reaction chamber outlet (8), d) positioning the coagulated thread at the reaction chamber outlet between at least two attachment points on or into a solid, liquid or gas collector (7) thereby allowing for the generation of a weave at the reaction chamber outlet and controlling the geometry of the fibrous mat, and e) optionally, drying the produced mat.
A method for producing a structured fibrous mat, comprising the following steps:
The method according to claim 11, wherein the separation in step c) is achieved by pulling the thread out of the liquid, sucking, or blowing away the liquid at the reaction chamber outlet, such as a nozzle, using liquid absorbing material, controlling the wetting properties of the reaction chamber outlet, or by using electrostatics forces at said outlet.
