Abstract: In an embodiment, the present invention provides a method for producing a structured microfilament non-woven, including: forming a non-woven by spinning microfilaments and/or composite filaments that can be split into microfilaments to form at least one fiber layer, stretching the at least one fiber layer, and laying the at least one fiber layer; thermally pre-bonding the non-woven; treating the thermally pre-bonded non-woven using a pressurized medium in order to break the thermal pre-bonding at least in part; and further applying a pressurized medium to the non-woven while the non-woven is resting on a structure-producing surface, so as to obtain a structured microfilament non-woven.
