Filamentous textile structures are produced from a quasi continuous planar nonwoven (1) by subjecting the nonwoven (1) to fluid-dynamic forces, namely in such a way that the nonwoven (1) is split up longitudinally into a plurality of parallel slivers (3) and the fiber structure of the nonwoven (1) is bonded in the slivers. For the treatment with fluid-dynamic forces, the nonwoven (1) is placed for example against a treatment template (10) which is structured in a strip-like manner by perforations (11) and elevations (12) and fine water, saturated steam or air jets (13) are directed against the nonwoven (1) and the template (10). The slivers produced during the treatment with the fluid-dynamic forces can be processed without any further treatment into a planar textile structures or they can be subjected to a further treatment prior to said processing in order to increase their strength. Said further treatment can preferably be performed without any application of additives (false twist, rubbing) or it is a further treatment which can be reversed after the production of the planar structure (treatment with glue). The slivers (3) have a relatively large volume and can therefore be weaved into covering fabrics with relatively low thread densities. They are suitable for example as weft yarns in fabrics for low-quality needs such as fabrics for disposable linens.
