Abstract (en)

[origin: WO2017025271A1] Method for producing a structured microfilament nonwoven, in which microfilaments and/or composite filaments that are able to be split into microfilaments are spun to form at least one fibre layer, drafted and laid to form a nonwoven; the nonwoven is thermally preconsolidated; the thermally preconsolidated nonwoven is treated with a pressurized medium in order to at least partially break up the thermal preconsolidation; the nonwoven resting on a structuring surface is subjected again to a pressurized medium, whereby a structured microfilament nonwoven is obtained.
