ABSTRACT:
In the case of a process and an arrangement for pneumatic flase-twist spinning having at least one pneumatic false-twist nozzle arranged between a drafting roller device and a withdrawal device, it is provided that the reversing of the twist applied to the sliver by the false-twisting nozzle is at least partially prevented and that fiber ends are spread away from the sliver in the area having an at least reduced twist. In certain embodiments, it is provided that the sliver is only prestrengthened by means of the false-twist spinning and is finished by a subsequent spinning or twisting process.
