FIELD: manufacturing technology.
SUBSTANCE: method and device for producing non-woven materials are described. Method involves the following stages: a) providing a three-phase (gas-liquid-solid) suspension containing air, water, fibrous material and a surfactant; b) depositing the suspension on a moving mesh carrier to obtain a fibrous web on the carrier; c) removing aqueous residue of suspension through mesh carrier; d) pumping of water residue, substantially in horizontal direction through one or more vessels for separation of phases with provision of free space under pressure not above pressure; e) recycling an aqueous residue pumped at step d) to step a); f) preferably preliminary integration of fibrous web.
EFFECT: method and device for wet laying of non-woven materials are disclosed.
