FIELD: metallurgy.
SUBSTANCE: present invention discloses composite nonwoven sheet material making method, involving continuous fibres extrusion from drawing-block, drawing fibres through slit drawing unit into thin continuous fibres, forming of web from loose continuous fibres without thermal connections during fibers laying, web spunlacing, including continuous spun fibres together with short fibers molded by wet or foam method, including natural and/or synthetic fibres or spun fibres, for integration and mechanical connection and forming of thermally unbound composite nonwoven sheet material, wherein creating wet environment during molding and stacking of continuous fibres on stages of fibres laying on already moistened surface, maintaining width of slit drawing unit outlet, opened for more than 65 mm, and liquid is added at slit drawing unit outlet.
EFFECT: production of material.
