Abstract (en)
[origin: EP0391260A1] A fiber bundle (2) comprising a plurality of composite fibers spun out of a spinneret (1) is blown against a working net conveyor (4) by a drawing force of a high-speed air stream while the air stream is sucked and removed from below the net conveyor (4) to deposit the fiber bundle on the net conveyor (4) to form a web (5), and the web (5) is then heat-treated to develop crimps and the fibers thermally adhere together at their points of contact, thereby obtaining a nonwoven fabric, wherein the air stream is blown against the web (5) from below the net conveyor (4) for a time before the heat-treatment, with an intensity sufficient to make the web to float in such a manner that the bottom face of the web rise above the net conveyor (4) by 0.2 to 30 mm.
