Problems solved by technology

However, other properties of the air-spun yarn are also adversely affected when the spinning pressure and / or spinning speed are changed, as a result, although the degree of hairiness is improved, but only at the same time that the yarn properties such as yarn stability are generally weakened do it without

Embodiment Construction

[0059] In air spinning machines such as figure 1 In the spinning station 1 shown, a fiber sliver 3 is fed to an air spinning nozzle 4 and spun there to form a yarn 2 . To this end, the fiber sliver 3 is first drafted by means of the drafting device 16 and then fed to the rotor spinning nozzle 4 via the inlet 5 . In the region of the air spinning nozzle 4 there is a blowing nozzle 18 which turns the outer fibers of the fiber sliver 3 around the fibers in the center of the fiber sliver 3 and thus forms the yarn 2 by means of the yarn former 17 . For this purpose, the spinning station 1 has a compressed air system 20 comprising a compressed air source 21 and a control device 22 .

[0060] The yarn 2 thus produced is then guided from the air spinning nozzle 4 through the yarn channel of the yarn former 17 to the outlet 7 in the outlet zone 6 to be subsequently wound. Also in the outlet area 6, after the outlet 7 in the yarn unwinding direction, there is an unwinding nozzle 8 thr...

Abstract

The invention relates to a spinning position, an air spinning machine and a method for producing the yarn. A spinning position for producing a yarn from a fed fiber band, having an air spinning nozzlewith an inlet opening for the fed fiber band and an outlet area with an outlet opening for the spun yarn is provided. In order to provide a spinning position, an air spinning machine and a method which allow for the yarn surface finish to be modified advantageously without the yarn properties deteriorating at the same time, while also avoiding expensive and complex modifications to the spinning position, there is provision for a navel to be arranged in the outlet area behind the outlet opening for modifying the surface finish of the spun yarn.

Description

technical field [0001] The invention relates to a spinning station and an air spinning machine for producing yarn from a supplied fiber sliver, with an air spinning nozzle having an inlet for the supplied fiber sliver and with an air spinning nozzle for the air spinning The exit area for the exit of the yarn. The invention also relates to a method for producing yarns with modified surface properties. Finally, the invention relates to the use of unwinding nozzles for modifying the surface properties of the rotor-spun yarn in the exit region of the rotor of the spinning station. Background technique [0002] Various designs of spinning stations and open-end spinning machines are known from the prior art and are also commonly used in addition to rotor spinning machines for the production of fiber materials, especially fiber slivers fed to the spinning station. Yarn machine. [0003] In air spinning, the draft sliver or fiber sliver is usually drafted according to the yarn ti...
